Louisiana Purchase

In 1803, the U.S. purchased the land from the Mississippi River to the Rocky Mountains from Napoleon for $15 million. Jefferson was interested in the territory because it would give the U.S. the Mississippi River and New Orleans (both were valuable for trade and shipping) and also room to expand. Napoleon wanted to sell because he needed money for his European campaigns and because a rebellion against the French in Haiti had soured him on the idea of New World colonies. The Constitution did not give the federal government the power to buy land, so Jefferson used loose construction to justify the purchase.

Law of Gravity Explanation (=Newton's law of universal gravitation)

Law of gravity affects motion *As one or both objects masses increase, the more gravitational force is exerted between them* (because if F = G(m₁*m₂/r²), when m's increase, the numerator increases, increasing the overall number G is multiplied by, so F (gravitational force) increases). *As the distance between 2 objects increases, the force of gravity is lessened exponentially.* (because if F = G(m₁*m₂/r²), when r (=distance) increases, the denominator increases and is squared, decreasing the overall number G is multiplied by very quickly, so F (gravitational force) decreases).

Closure

"Closure is a property of operations. Number sets are closed under addition and multiplication, but not under subtraction or division. This means that you can add any two whole numbers and the result will be a whole number. But you can't subtract any two whole numbers and be guaranteed that the result will be a whole number (it might be a negative number, which is not a whole number). This term will probably not appear on the Praxis test but is included here for completeness of mathematical topics."

Concave

"Concave describes an object with a hollowed out or cut out portion—a part of the object has been "caved" in. The opposite of a concave polygon is a convex polygon. <img src=""pastem9enkn.png"" />"

Convex

"Convex describes an object such as a polygon that is not concave. All vertices of a convex polygon are less than 180-degrees in measure: <img src=""pastecrexir.png"" /> The opposite of convex is concave."

Deductive Reasoning

"Deductive reasoning is a form of logic starting with statements of fact and drawing logical conclusions. If the laws of logic are followed from the statements of fact, the conclusions are true. It often helps to draw logic circles when working with deductive reasoning. Inductive reasoning is making sufficient observations that conclusions can be formed. A trick to remember the difference: Deductive reasoning = Drawing logical conclusions from factual statements Inductive reasoning = I-witness (eye-witness) observations    "

Density

"Density is the measure of how compact the material is inside an object. Density is measured in terms of the mass per unit volume.

This term will probably not appear on the Praxis test but is included here for completeness of mathematical topics."

Discounts

"Discounts are usually written as percentages. A discount is an amount by which the purchase price is reduced. Be careful when working with discount problems because the answer may be the discount percentage, an amount of money discounted, the sales price after the discount, or the original sales price. Discount amount is the original sales price multiplied by the percentage of discount. The discounted price is the difference of the original price and the discount amount. <img src=""pastez1nm88.jpg"" />"

Discrete Data

Division of Whole Numbers

"Division of whole numbers is the inverse of multiply and is repeated subtraction. We divide to find how many groups of a number (the divisor) can be created from another number (the dividend). The symbol ÷ is used to signify division; it means "divided by." The algorithm for division Is: Divide the divisor into the digit in the largest place value of the dividend, multiply, subtract, bring down the next digit, and divide again. <img src=""pastexskq85.png"" />"

Probability

"Probability is the ratio of how likely a specific event is to happen when compared to all possibilities of events that might happen. Probability is most often written as a fraction, but it may also be written as a decimal or a percentage. The numerator of the fraction tells how many possibilities of a specific event, the denominator tells how many total possibilities. For example, in a deck of face cards, the probability of drawing a heart is 13 out of 52 (13 hearts in a deck of 52 face cards). That is written as 13/52 but simplified to 1/4.    The three types of probabilities are classical, empirical, and subjective. "

Other examples of quantitative variables are heights, weights, and body temperatures. <img src=""pasteo0hvqs.png"" /> This term will probably not appear on the Praxis test but is included here for completeness of mathematical topics."

Reduce a Fraction

"Reducing a fraction is the same as simplifying a fraction. The term "reduce" is seldom used in mathematics today. To simplify a fraction, expand the numerator and denominator into prime factorizations. "Cancel" any ones such as 3/3 or 5/5. Then multiply straight across those numbers that are left. True story: When I did my student teaching 40 years ago, I was teaching how to add fractions and I used the term "reduce" a fraction. After the lesson, my cooperating teacher took me aside and told me to use "simplify" instead -- he said, "Jolene, only women reduce. Fractions simplify." "

Roman Numerals

"Roman numerals and the Roman number system are similar to the Arabic number system used in the United States. The Roman number system is based on 10 so it is decimal, but it does not have place value. Letters are used to represent various numbers (Roman number names). The rule with Roman numbers is to write the numbers in descending order (from greatest to smallest). The exception to this rule is if a smaller number comes before a larger number, we subtract that smaller number from the larger number.   I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1,000 "

Sales Tax

"Sales Tax is written in percentages (which are converted to decimal to computer sales tax). The final purchase price of an item = marked price + (sales tax times marked price). Using FP for final price, MP for marked price, and ST for sales tax, the algebraic equations is: FP = MP + (ST × MP) If you know two of those three amounts, you can use basic algebra to find the missing number. Remember to state the sales tax as a percentage in application problems. "

Scientific Notation

"Scientific Notation is a way to write very large or very small numbers using powers of 10. To convert a number into scientific notation, move the decimal point so the resulting number is between 1 and 10. Then state the power of 10. Because we use a Base 10 number system, an easy way to know what power of 10 is needed, the exponent indicates the number of decimal places the decimal point was moved. The exponent is negative if the decimal point was moved to the right; the exponent is positive if the decimal point was moved to the left. 1234.5 <img src=""pastexurkr0.jpg"" /> 1.2345 × 103"

"A line graph is a statistical graph showing the data points connected by line segments. A line graph is used to visualize trends in the data. The graphic below is a line graph showing two trend lines. <img src=""pastet1aa0g.png"" />"

Line Segment

"A line segment is a portion of a line with two endpoints. The line segment is named by the two endpoints. The symbol for a line segment is a line segment placed above the two endpoint letters: <img src=""pastewodbmg.png"" />"

Line (geometry) -- How is a line named?

"A line is an infinite collection of collinear points. A line has no width or depth—it has only one dimension: length. A line is named with a lowercase letter or by two points on the line. The symbol for a line is a double headed arrow. Thus, the line below is line l,  or <img src=""pasterfgrge.png"" /> <img src=""paste9jxvzp.jpg"" /> "

Literal Equation

"A literal equation is an equation made up of only known, measurable quantities. A literal equation is the same as a formula. With a literal equation, you are not solving for an unknown quantity that varies. Instead, you are manipulating the letters/variables in the equation to a different form to substitute values in it. This term will probably not appear on the Praxis test but is included here for completeness of mathematical topics. "

Logic Diagram

"A logic diagram is a visual way to determine the truth or logic of statements. A truth table may also be used. With a logic diagram, use circles to show relationships. For example:  (1) ALL cats have tails. (2) SOME cats are black. (3) Goldy is a cat. ALL means the circle is completely inside another circle. SOME means the circle is partially inside another circle. NONE means the circles are completely separate. <img src=""pastefezadz.png"" /> From the logic diagram above, we see that Goldy definitely has a tail but may or may not be black. "

Mixed Number

"A mixed number is a whole number and a proper fraction combined. Mixed numbers may also be called mixed fractions. <img src=""paste65g730.jpg"" /> This graphic shows two whole pizzas and a fraction of 3 pieces out of 4  <img src=""pasteey5lnj.jpg"" /> 2 3/4 "

Monomial

"A monomial is a polynomial with a single term. A term contains a coefficient with possibly one or more variables all multiplied. Neither a term nor a monomial has any addition or subtraction. Here are samples of four monomials:<div> </div><div style=""font-style:italic; font-size: 1.3em; font-family:cambria;"">3        3x        3x2       x5 </div>"

"A net is a two-dimensional representation of a three-dimensional object. If a net is cut out, it can be put together to form the three-dimensional object it represents. <img src=""pastega8pp2.png"" /> "

Number Line

"A number line is a straight line where each point of that line corresponds to a real number. A line is made up of an infinite number of points and there are an infinite amount of real numbers. Usually the line is marked off to show the integers, including zero. A number line is generally written as a horizontal line. <img src=""pasteoetkwm.png"" />"

Number Squared

"A number squared is the same as the number times itself. The exponent of 2 is often called squared because the area of a square is the side times itself. n2 = n squared = n × n"

"A polygon is a two-dimensional shape drawn on a plane. A regular polygon is where all sides and all angles of the polygon have the same measure. <img src=""pastem4ndua.png"" />"

Polynomial (terms; degrees; types)

"A polynomial is an algebraic expression with one or more terms. A polynomial cannot have a variable in the denominator (which is a negative exponent). A polynomial with one term is called a monomial; two terms, a binomial; and three terms, a trinomial. The term with the highest exponent (sum) determines the degree of the polynomial. <img src=""pasteerhr6y.jpg"" />"

Prism

"A prism is a three-dimensional object with two bases of the same figure. The side faces of a prism are quadrilaterals. Prisms are named according to their bases. As such, if the two bases are triangles, it is a triangular prism. If the two bases are hexagons, it is a hexagonal prism. <div> </div><div style=""font-style:italic; font-size: 1.3em; font-family:cambria;"">V = area of base × height</div>"

Proportions (How to Solve)

"A proportion is when two ratios are equivalent: <img src=""paste4snc75.png"" /> When two ratios are equivalent, the cross products are equal. Thus, to solve a proportion, cross multiply the two numbers that are diagonal from each other, and then divide by the number diagonal from the unknown. <img src=""pastewj9gxm.png"" /> "

Protractor

"A protractor is a geometry tool used to measure angles. Place one ray of the angle along the zero edge of the protractor. The other ray of the angle points to the number of degrees that are in the angle. <img src=""pastev1xnd2.png"" />"

Pyramid (geometry)

"A pyramid (in geometry) is a three-dimensional object. The base of the pyramid is a polygon. Line segments connect the base of the pyramid to a single point, called the apex. Each base edge and the apex form a triangle -- thus all faces of a pyramid (except the base) are triangular. <img src=""pastexr4d5j.png"" />   <img src=""pastei5rbce.png"" />"

Quadratic Equation (definition & five ways to solve)

"A quadratic equation is a second-degree polynomial equation (the exponent on the leading term is a 2). There are many ways to solve a quadratic equation, but the five most common ways are: 1. Factor and set each factor equal to 0 2. If there is no x-term, solve for x2 and apply the square root method. 3. Graph the equation (as a parabola) and determine the solutions where the parabola crosses the x-axis 4. Complete the square 5. Use the quadratic formula This term will probably not appear on the Praxis test but is included here for completeness of mathematical topics. "

Quadrilateral

"A quadrilateral is a polygon with four sides (and four vertices). Other names for a quadrilateral are a quadrangle and a tetragon. The interior angles of a quadrilateral add to 360◦.

Radius

"A radius is a line segment that goes from the center of a circle to any point on the circumference of the circle. The measure of the radius is half the diameter. Often, the term radius is also used to denote the measure of the radius line segment. <img src=""pasteqjplvi.png"" />"

Ray (geometry)

"A ray is often mistakenly called a half line. A ray is part of a line that has an endpoint but goes infinitely in a straight line from that endpoint. Two rays that have the same endpoint form an angle. A ray is named by its endpoint and any other point on the ray. The symbol for a ray is a small ray (single headed arrow). <img src=""pasteqch7ya.png"" />"

Reciprocal

"A reciprocal is a fraction where the numerator and denominator have been switched. Multiplying any fraction by its reciprocal results in an answer of 1. As such, a reciprocal is called a multiplicative inverse. NOTE: Since there is no rule on how to divide fractions, but because multiplication is the inverse of division and a reciprocal is the inverse of a fraction, you can divide fractions by multiplying by the reciprocal of the divisor. Hence, the inverse of an inverse results in the same answer as if you had divided. "

Relationships (data pairs)

"A relationship is simply a set of ordered pairs. If the set of ordered pairs has only one y-value for any x-value, this relationship is a function. If the set of ordered pairs has only one y-value for any one x-value, it is a function with a one-to-one correspondence. This term will probably not appear on the Praxis test but is included here for completeness of mathematical topics."

Rhombus (Definition, perimeter, & area)

"A rhombus is a two-dimensional quadrilateral where all four sides are the same length. Thus, a square is a specialized rhombus.    <img src=""pastewevixu.png"" /><div> </div><div style=""font-style:italic; font-size: 1.3em; font-family:cambria;"">P = 4s</div><div style=""font-style:italic; font-size: 1.3em; font-family:cambria;"">A = bh </div>"

"A right triangle is a triangle in which one angle is a right angle. The right angle is usually marked with a small square: <img src=""paste4dlk9j.png"" />"

Scatter Plot

"A scatter plot is a graph showing a collection of two-coordinate points. The points are not connected with line segments, but the points may demonstrate a trend. A technique called the "line of best fit" determines a line through the points where about half of the points are above the line and about half the points are below the line. This line of best fit visually demonstrates a trend. <img src=""pastenavbm4.png"" />"

Sets

"A set is a collection of objects. The objects in a set can be numbers, expressions, and other mathematical objects. Georg(e) Cantor developed set theory in the late 1800's. Common operations on sets include intersection, union, complements, and Cartesian products. Other concepts include the Universal set, Null set, members or elements, and sub-sets. Sets in mathematics include the set of integers (Z), rational numbers (Q), primes (P), real numbers (R), natural numbers (N), etc. This term will probably not appear on the Praxis test but is included here for completeness of mathematical topics. "

Simulation

"A simulation is a game, computer program, or device that approximates a real-life event. Simulations are used when actual events are dangerous or impractical to duplicate. Examples of simulations are driving teaching machines, dissection of frogs, and chemical experiments. Simulations are used in statistics to approximate results from a real-life event. This term will probably not appear on the Praxis test but is included here for completeness of mathematical topics."

Sphere (definition, volume & surface area)

"A sphere is a three-dimensional, perfectly round shape. Sphere is from the Greek word for "ball." <img src=""pasteenjykf.png"" /> <img src=""paste6krvua.png"" /> Technically, in mathematics, a sphere only includes the "surface" and not the interior. "

Table (of Data)

"A table is used to display the information in an organized manner. A table usually has column headings -- each record is in a row of the data table. <img src=""paste9ycib5.png"" /> <a href=""http://earthquake.usgs.gov/regional/neic/"">http://earthquake.usgs.gov/regional/neic/</a>"

Transversal

"A transversal is a line that crosses two or more other lines. A transversal of two lines forms eight angles that are often used in geometrical problems (see: vertical angles, adjacent angles, corresponding angles, interior angles, and exterior angles). <img src=""pastepuu9z8.png"" />"

What is a Tree Diagram? What is it used for?

"A tree diagram is a graphic organizer that lists all possibilities of a sequence of events in a systematic way. A tree diagram is used in determining probability - it is a way to calculate the total possible outcomes and view each possible scenario. <img src=""pastebn9e6n.png"" />"

Trend

"A trend is the general direction data tends to move. From a line graph, a trend can be obvious when the line is going in an up or down pattern. Example: In the stock market, when stocks are trending down, it is called a bear market. When stocks are trending up, it is called a bull market. (A mnemonic to remember which is which: A bear has claws that curve downward and a bull has horns which curve upward.) <img src=""pasteaiankc.png"" />"

Trinomial

"A trinomial is an algebraic expression with exactly 3 terms Example:  3x2 + 2x - 1"

Vertex

Decimal System Place Value

"A number in standard form is marked into groups of three digits. Each of these groups is called a period. Within each group, the place values are always the 100's place, the 10's place, and the 1's place. Decimal numbers simply extend the place values to the right and use "ths" to identify the places (e.g. 100 millionths place). There is not a oneths place. <img src=""paste6wllx9.png"" />"

Dependent Variable

"A dependent variable is one that depends on another variable (independent variable) for its value. In an equation with two variables, you can choose any value you want for one of them (the independent variable), but once that value is chosen, the dependent variable has limited values in order for the equation to be true. Dependent and independent variables are often interchangeable - in an equation with an x-variable and a y-variable; it doesn't matter which variable you choose a value for, but that sets the value of the other variable. This term will probably not appear on the Praxis test but is included here for completeness of mathematical topics."

Common Factors

"All counting numbers (except 1) have at least two factors. Common factors are those factors that are in common with two or more numbers. For example,    The factors of 6 are 1, 2, 3, and 6    The factors of 9 are 1, 3, and 9    The common factors of 6 and 9 are 1 and 3 "

Common Multiples

"All counting numbers have an infinite number of multiples. Common multiples are those multiples that are in common with two or more numbers. For example,     The multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18, etc.     The multiples of 3 are 3, 6, 9, 12, 15, 18, etc.     The common multiples of 2 and 3 are 6, 12, 18, etc. "

Arithmetic Sequence

"An arithmetic sequence is an ordered list of numbers where each number is formed by adding a constant number to the previous number. An example of an arithmetic sequence is: 3, 6, 9, 12, 15, 18, etc. where each number is formed by adding 3 to the previous number. An arithmetic sequence may be written algebraically as  an = an-1 + k Do not confuse this with an arithmetic series where numbers are not is a list but form an addition problem. An example of an arithmetic series is 3 + 6 + 9 + 12 + ... "

Equilateral Triangle

"An equilateral triangle is one where all three legs (sides) are of equal measure. An equilateral triangle is also equiangular, which all three angles are of equal measure (60°). In diagrams representing triangles (and other geometric figures), "tick" marks along the sides are used to denote sides of equivalent lengths: <img src=""pastezot6cz.png"" />"

Exponent

"An exponent is a symbol to indicate a shortcut of multiplication by the same number. The exponent signifies the base is multiplied by itself (not by the exponent) the exponent number of times.

Scale on Bar or Line Graph

"Bar graphs and line graphs will often have a symbol on the vertical axis to indicate that some numbers have been left out. Be aware of these "broken scales" when analyzing graphs. The break in the scale is used when one or more of the bars/lines are significantly out of range of the other bars/lines. These broken scales can visually give a wrong impression. In the bar graph below, the red bar looks about twice the size of the green bar; whereas, the red bar is actually six or seven times the size of the green bar! <img src=""pastevduqsu.png"" />"

Multiplying by Powers of 10

"Because we use a Base 10 number system, each place value is 10 times the place value to its right. As such, multiplying by powers of 10 is simply a matter of moving the decimal point to the right (one place for each power of 10).   Example:   123.456 × 102 = 123.456 × 100 = 12345.6 In this example, we were multiplying by 10 to the power of 2, which is a 1 followed by 2 zeroes, so we merely move the decimal point 2 places to the right. "

Sum of Interior Angles

Quartiles

"In statistics, quartiles are three points that divide a set of ordered data into four equal groups. The first quartile, also called the lower quartile, splits off the lower 25% of the data. It is denoted by Q1 The second quartile, also called the median, splits the data in half. It is denoted by Q2 The third quartile, also called the upper quartile, splits off the higher 25% of the data. It is denoted by Q3 This term will probably not appear on the Praxis test but is included here for completeness of mathematical topics. "

Sample (statistics)

"In statistics, often the population is too large to test everything in the population. Instead, a subset of the population is tested. This subset is called a sample. An entire college class is offered at most large universities to explain the best way to sample a representative subset of the population without introducing bias. This term will probably not appear on the Praxis test but is included here for completeness of mathematical topics."

Comparing Decimal Numbers

Square Root of a Number

"The square root of a number is the value when multiplied by itself makes the number. A number's square root is always smaller than half of the number. The symbol for square root is called a radical sign. There is an index of 2 on the radical sign, but an index of 2 is rarely written -- it is understood to be 2 if not written. Finding a square root is the inverse of squaring a number. Although -6 times -6 also makes 36, we always use the positive square root (also called the principal square root). <img src=""pastejysnds.png"" />"

"The term standard deviation is used in statistics to describe how much the results deviate (differ) from the mean (average). A small standard deviation indicates that most of the data values are close to the mean. A large standard deviation indicates that the data have a large range of values. This term will probably not appear on the Praxis test but is included here for completeness of mathematical topics. "

Legs of a Triangle

"The legs of a triangle are the sides of the triangle. In a right triangle, the legs are usually labeled "a" and "b". The legs are the two shorter sides of a right triangle. The legs of a right triangle are perpendicular to each other.     <img src=""pasted1v_n8.png"" />"

Percentages, the three types of problems

"There are three types of percentage problems depending on what value is missing in the equation: What number is 15% of 45? <img src=""pastexurkr0.jpg"" />   x = (0.15) ∙ (45) What percent of 45 is 15?     <img src=""pastexurkr0.jpg"" />  45 ∙ x = 15  or 45x = 15 15% of what number is 45?  <img src=""pastexurkr0.jpg"" />  (0.15) ∙ x = 45 or 0.15x=45 "

Interest

"There are basically two kinds of interest: simple and compound. Simple interest is paid on the principal amount only. Compound interest is paid on the principal amount plus accrued interest. The formula to find simple interest is I = prt where p is the principal, r is the interest rate, and t is the time period.    The formula to find compound interest is A = p(1 + r)n where p is the principal, r is the interest rate, and n is the number of interest periods. "

Percentages, Solving

"There are two ways to solve a percentage problem. To solve percentages using the percent proportion, use the means-extreme property of proportions (cross multiply). The percent proportion can be written as: <img src=""pasteh2sohc.png"" /> The second way to solve a percentage problem is with simple algebra: Write the percentage as an algebraic equation where "what number" → variable (x),   is → =,   and of → multiply. Then solve the equation. "

Evaluate Algebraic Expressions

"To evaluate an algebraic expression, substitute the given values for each variable into the expression, and then follow the order of operations (PEMDAS) to simplify the expression. 1. Perform the operations inside a parenthesis first 2. Then follow rules for exponents 3. Then multiplication and division, from left to right 4. Then addition and subtraction, from left to right"

Simplifying Square Roots

"To simplify square roots, take out the square root of any perfect squares that are factors inside the radicand. Perhaps the easiest way to do this is the factor the number inside the radicand so it is obvious which factors can be taken out. Example: Simplify <img src=""pastenr9prq.png"" /> <img src=""paste2w8pyb.png"" />"

Solving Percentages (using the algebraic equations)

"To solve percentages using algebra, write the problem as an algebraic statement where what number <img src=""pasteeimgot.jpg"" /> variable (x) is <img src=""paste_ubim_.jpg"" /> = of <img src=""pasteiboybt.jpg"" /> multiply What number is 15% of 45? <img src=""paste_vyywq.jpg"" />   x = (0.15) ∙ (45) What percent of 45 is 15?     <img src=""pasteey5lnj.jpg"" />  45 • x = 15  or 45x = 15 15% of what number is 45?  <img src=""pasteuwfwqh.jpg"" />  (0.15) • x = 45  or 0.15x=45 "

Solving Percentages (using the Percent Proportion)

"To solve percentages using the percent proportion, use the means-extreme property of proportions (cross multiply). The percent proportion can be written as:    <img src=""pasteh2sohc.png"" /> "

Writing Algebraic Expressions (from English statements)

"To write an algebraic expression from an English statement, we convert each word or phrase to the equivalent algebraic symbol. For example, "of" means to multiply, "per" means to divide, "total" means addition, and "is" means equals. Other flashcards contain ALL common words that can be converted to algebra. Here's an example:  The sum of two numbers is 16. One of the numbers is twice the other number.    x + y = 16     x = 2y"

Adjacent Angles

"Two angles are adjacent angles if they share a common vertex, they share a common side, AND they do not share any interior points. In other words two angles that are side-by-side are adjacent. <img src=""pastequlmnb.png"" />"

Intersecting Lines

"Two lines on the same plane that share a single point are said to be intersecting lines.   <img src=""pastevfekmv.jpg"" />"

Bimodal Distribution

"When a list of numbers has TWO numbers that appear the most, this distribution of numbers in the list is called a bimodal distribution. For example, this list is a bimodal distribution with 3 and 7 as the two modes: <img src=""pastem841zv.jpg"" /> "

Corresponding Angles

"When a transversal line crosses two other lines, it forms eight angles that are often used in geometrical problems. Corresponding angles are angles that are in the same position on each of the lines. In the figure below, Angle 2 corresponds to Angle 6. <img src=""pasteucky2t.png"" />"

Vertical Angles

"When two lines intersect, they form four angles. The two angles opposite each other are called vertical angles. Vertical angles are always the same measure. In the drawing below, Angle 1 and Angle 3 are vertical angles. Angle 2 and Angle 4 are vertical angles. <img src=""paste1g3y38.png"" />"

Words that Signal Addition

"• add • sum • increase • total • rise • plus • grow • added to • more than • increased by • gain <img src=""pasteanxscw.jpg"" />"

Words that Signal Division

"• divide • divided by • quotient • per • ratio • half <img src=""pasteanxscw.jpg"" />"

Although his criticisms of the Church led to the Reformation, he opposed violence and condemned Martin Luther. He wrote The Praise of Folly and translated the New Testament from Greek to Latin.

Niccolo Machiavelli

(1469 CE - 1527 CE) A Florentine historian and political theorist. He wrote "The Prince" in 1513. It was a handbook for politicians about how governments most effectively work, not necessarily how the should morally work. It described how politicians should gain and maintain power. Believed that the government should be feared.

Michelangelo di Lodovico Buonarroti Simoni

(1475 CE - 1564 CE) An Italian sculptor, painter, poet, engineer, and architect. Famous works include the mural on the ceiling of the Sistine Chapel, and the sculpture of the biblical character David.

Sir Thomas More

(1478 CE-1535 CE) Renaissance humanist and chancellor of England. H was executed by Henry VIII for his refusal to acknowledge his king publicly as Supreme Head of the Church Clergy of England. He believed that the basic problems of society were caused by greed. Law should exalt mercy above justice. Citizens who live by reason will live a nearly perfect life. He also wrote Utopia.

Jacques Cartier

(1491 CE -1557 CE) A French explorer who explored the St. Lawrence River and laid claim to the region for France.

The Renaissance

(14th Century CE - 17th Century CE) "Renaissance" literally means "rebirth." It refers especially to the rebirth of learning that began in Italy in the fourteenth century, spread to the north, including England, by the sixteenth century, and ended in the north in the mid-seventeenth century (earlier in Italy). During this period, there was an enormous renewal of interest in Ancient Greek and Latin Art, literature, and philosophy, It was also a time of great scientific inquiry, the rise of individualism, extensive geographical exploration, and the rise of secular values.

Industrial Revolution

(1733 CE - 1840's CE) Social and economic change that began in England in with the construction of the Cotton Mill in 1733. The industrial geography of England changed significantly and later diffused to other parts of western Europe. In this period of rapid socioeconomic change, machines replaced human labor and new sources of inanimate energy were tapped. Coal was the leading energy source fueling the industrial revolution in England's textile-focused industrial explosion. Men, women, and child worked up to 14-hour work days, which would eventually lead to Unions and Child Labor Laws.

American Revolution

(1775 - 1783) The American Revolution was a political upheaval that took place between 1765 and 1783 during which rebel colonists in the Thirteen American Colonies rejected the British monarchy and aristocracy, overthrew the authority of Great Britain, and founded the United States of America.

Issued the Declaration of Sentiments which declared men and women to be equal and demanded the right to vote for women. Co-founded the National Women's Suffrage Association with Susan B. Anthony in 1869.

World War 1

(1914-1918) First time all European Countries are engulfed in one war (Italy, Austria-Hungry, and Germany, against France, Russia, Great Britain) as a result of Industrial Revolution, scramble for Africa, and alliance systems. At least 20 million people died. The assignation of Archduke Ferdinand was the breaking point. The war ended the Empire system throughout the world.

Great Depression

(1929-1939) The dramatic decline in the world's economy due to the United State's stock market crash of 1929, the overproduction of goods from World War I, and decline in the need for raw materials from non industrialized nations. Results in millions of people losing their jobs as banks and businesses closed around the world. Many people were reduced to homelessness, and had to rely on government sponsored soup kitchens to eat. World trade also declined as many countries imposed protective tariffs in an attempt to restore their economies.

Cold War

(1945-1991) The period after the Second World War marked by rivalry and tension between the two nuclear superpowers, the United States and the communist government of the Soviet Union. The Cold War ended when the Soviet government collapsed in 1991.

mixture

*seems like a chemical reaction but IS NOT* *NO CHEMICAL CHANGE* material that can *be separated by PHYSICAL MEANS into TWO OR MORE substances* 2 Types of mixtures: *solution*: homogeneous (even throughout) mixture where 1 substance is evenly dissolved into the other (i.e. salt water/saline solution: salt evenly distrib. throughout the water) *suspension*: small particles are kept dispersed throughout the mixture by agitation only (agitation = molecular motion in the surrounding medium) (i.e. muddy water in river - churning of water in river keeps mud mixed into the water, but if water was still, would separate due to gravity) *if separates due to simply gravity when agitation ends, it was a suspension*

Valence electrons are important because

*they are involved in chemical bonding, either being transferred or shared* -they give atoms their properties because of how they are transferred or shared -they can be shared, gained or lost -There are some atoms - the noble gases - that have valence electrons that don't change, but most atoms have valence electrons that change. -they are the electrons in the outer shell of an atom.

What causes waves?

*wind stirs the ocean's surfaces over great distances* wind pushes on water particles as waves get closer to land don't have enough room to rotate, so build up higher and higher shallow water means wave cannot rotate down (not enough room) so it builds up into a taller wave *do not confuse with TIDES, which are controlled by the moon*

Negative and Positive Multiplication/Division Rules

+ times + = + Ex: 2 * 3 = 6 + times - = - Ex: 2 * -3 = -6 - times - = - Ex: -2 * -3 = 6 *Remember by: If a good thing happens to a good person, that's good If a good thing happens to a bad person, thats bad If a bad thing happens to a bad person, that's good

*Test Tips: Translating Word Problems into Equations*

1.) Last sentence of word problem = what the question is asking you to find out/what you actually need to solve (Begin with the end in mind) 2.) What do I wish I knew? What would you want to ask if you could ask the test makers to clarify? This could be a variable, like "x" you need to find. 3.) How can I work backwards to find this info? *Approximating can sometimes save time on multiple choice questions.* *Ex:* Tom is at a plant nursery where he spends a total of $41.92. Ferns are $5.24, avocado trees are $3.56, gardenias are $7.13 and succulents are $4.05. He buys a total of 8 of one type of plant. What plant does he buy? Can estimate to guess: Ferns: 8 x $5 = $40 Succulents: 8 x $4=$32 ^^ Already know the answer is ferns because others would be either more than or less than $40. *Ex2:* How much do 11 ferns cost? (fill in the blank) Do TEN x (price), then add one more, because it is much faster to do that mental math. 10 x $5.24 = $52.40 + $5.24 = $57.64

Common Equivalents 1/2 = 0.5 = 50% 1/3 = 0.33 1/3 = 33 1/3% 2/3 = 0.66 2/3 = 66 2/3% 1/4 = 0.25 = 25% 3/4 = 0.75 = 75% 1/5 = 0.2 = 20% 2/5 = 0.4 = 40% 3/5 = 0.6 = 60% 4/5 = 0.8 = 80% 1/6 = 0.16 2/3 = 16 2/3% 5/6 = 0.83 1/3 = 83 1/3% 1/8 = 0.125 = 12.5% 3/8 = 0.375 = 37.5% 5/8 = 0.625 = 62.5% 7/8 = 0.875 = 87.5% 1 = 1.0 = 100% 2 = 2.0 = 200% 3 1/2 = 3.5 = 350%

Decimal Number Subtraction

Decimal numbers are subtracted exactly the same as whole numbers: line up the numbers by place value and subtract each place value from the right to the left. When the decimal numbers are lined up by place value properly, the decimal points in each number are also lined up. Any number without a decimal point is lined up so the ones place is right before the decimal point (there is an understood decimal point after the ones place). It may help to write zeros in empty places to facilitate subtraction.

Estimation

Estimation is a mathematical process of finding an approximate value of a variable, expression, or operation. The most common way to find an estimate is to round off the numbers in the problem to numbers that are easy to calculate and then find the answer to the rounded problem. The symbol for an estimated or approximate answer is ≈. For example:   287 + 321 + 878 ≈ 300 + 300 + 900 = 1,500

Even Numbers

Even numbers are integers that are evenly divisible by two (2). Zero is an even number.

Factoring Polynomials

Factoring Polynomials 1. Factor out any common factors in all terms. 2. If the polynomial has four terms, factor it by grouping. 3. If it is a binomial, look for a difference of squares, a sum of cubes, or a difference of cubes. (Note that a sum of squares cannot be factored.) 4. If it is a trinomial and the coefficient of the x² term = 1, un-FOIL to factor. 5. If it is a trinomial and the coefficient of the x² term is not 1, use the AC method to factor.

Central Tendency Measures

Measures of Central Tendency are statistical measures such as mean, median, and mode. Data has a tendency to cluster or center on certain values. The term "average" is also used to indicate measures of central tendency; as such, the mean, median, and mode are ALL averages.

Multiple of an Integer n

Multiples of integers are formed when the integer, n, is successively multiplied by the whole numbers. As such, the multiples of the integer 3 are 0, 3, 6, 9, 12, 15, etc. The way the "multiple of an integer n" is written in algebra is kn where "k" is a whole number.

Odds (Statistical)

Odds and probability are related concepts. With probability, you compare the number of favorable outcomes to the total possible number of outcomes. With odds, you compare the number of favorable outcomes to the number of remaining (unfavorable) outcomes. If you have a box with 2 red balls and 3 blue balls, the probability of randomly picking a red ball is 2 out of 5 or 2/5. The odds of randomly picking a red ball are 2 for and 3 against, or 2:3

Ordinal Numbers

Ordinal numbers, unlike cardinal numbers that indicate a quantity, are numbers that indicate order or rank. Ordinal numbers are 1st, 2nd, 3rd, 4th, 5th, etc., unlike cardinal numbers that indicate a quantity, are numbers that indicate order or rank. Ordinal numbers are 1st, 2nd, 3rd, 4th, 5th, etc.

Perimeter (Definition)

Perimeter is the measure of the distance around a polygon     (peri = around, meter = measure)

Positive Integers

Positive integers are those integers greater than zero. Positive integers appear to the right of zero on a number line. The positive sign is understood if it isn't written. Negative integers are the opposite of the positive integers. The number zero is neither positive nor negative.

Regrouping

Regrouping is the modern term that should be used instead of "carrying" and "borrowing." Children are now taught to add and subtract by keeping place value in mind. When we need to carry or borrow, we now teach students to re-group units into 10s or 10s into units.

Simultaneous Equations (definition and 3 ways to solve)

Simultaneous Equations are two or more equations with multiple variables. These are often called systems of equations. A solution gives values for the variables that are true for all equations in the system. There are many ways to solve a system of equations. Three ways discussed in beginning algebra are:<div>  1. Elimination (sometimes called adding) 2. Substitution 3. Graphing Another method presented in intermediate/advance algebra is the use of matrices.</div>

Through conquest and assimilation it came to dominate Southern and Western Europe, Asia Minor, North Africa, and parts of Northern and Eastern Europe. Ancient Roman society has contributed to modern government, law, politics, engineering, art, literature, and society. It achieved impressive technological and architectural feats, such as the construction of an extensive system of aqueducts and roads, as well as large monuments, palaces, and public facilities.

Ancient Greece

A civilization that lasted from the 8th/6th century BCE to 600 AD. Immediately following this period was the beginning of the Early Middle Ages and the Byzantine Era.

War of 1812

A war between the U.S. and Great Britain caused by American outrage over the impressment of American sailors by the British, the British seizure of American ships, and British aid to the Indians attacking the Americans on the western frontier. Also, a war against Britain gave the U.S. an excuse to seize the British northwest posts and to annex Florida from Britain's ally Spain, and possibly even to seize Canada from Britain. The War Hawks (young westerners led by Henry Clay and John C. Calhoun) argued for war in Congress. The war involved several sea battles and frontier skirmishes. U.S. troops led by Andrew Jackson seized Florida and at one point the British managed to invade and burn Washington, D.C. The Treaty of Ghent (December 1814) restored the status quo and required the U.S. to give back Florida. Two weeks later, Andrew Jackson's troops defeated the British at the Battle of New Orleans, not knowing that a peace treaty had already been signed. The war strengthened American nationalism and encouraged the growth of industry.

Rule of Threes *to solve Ratio/Proportion Problems*

Every proportion is made up of *4 numbers* (2 numerators and 2 denominators) If word problem gives you 3 out of the 4 numbers in a proportion problem, you can cross multiply and solve for the 4th (missing) number. (When you cross multiply a fraction/ration, equation should be linear, no longer fractions - see example) Ex: Margery is pouring orange juice for the kids in her class. She pours 3 cups every 2 minutes (Margery is super slow at pouring juice). How long will it take her to fill up 24 cups of juice? 3 cups/2 mins = 24 cups/x minutes *cross multiply to get:* 3x = 24*2 3x=48 x=16 It will take Margery 16 minutes to pour 24 cups of juice. (Get it together, Margery!) *TRICKY QUESTION!!*: If the question said: "Margary *poured* (as opposed to pourS) 3 cups *in* 2 mins....how long will it take for her to *finish* filling all 24 cups for her class?" then you would have to subtract out the 3 cups she ALREADY filled!! 24 cups total - 2 cups already filled = 21 cups left to fill 3 cups/2 mins = 21 cups/x minutes *cross multiply to get:* 3x = 21*2 3x=42 x=14 *BE VERY CAREFUL ABOUT THIS TRICK!*

How much louder is a 120-decibel sound than a 100-decibel sound?

One hundred times louder. One hundred (100) on the decibel scale is 10^10 (ten to the 10th power = 1,000,000,000) and 120 is 10^12 (ten to the 12th power = 100,000,000,000). So a sound that is 120 is 10^12, or 100 times louder than a sound that is 10^10. The decibel scale *goes up by a power of ten for every ten (10) decibels*, so 160 would be 10^16 and 40 would be 10^4.

English System of Measurement

The English System of Measurement is also called the Customary System of Measurement (or the Common System of Measurement). This is the primary measurement system used in the United States. Length = inch, foot, yard, rod, mile, etc. Weight = ounce, pound, Ton, etc. Volume = liquid ounces, cup, pint, quart, gallon, etc.

Median

The median is used in statistics to describe one of three measures of central tendency. To find the median, list all the data values in numerical order. The median is the middle data value. If there is an even number of values, find the mean (or average) of the middle two values. Medians are used instead of means when there are outliers in the list of values that would distort the average. A mnemonic used to remember this term is to think of the median in the center of a freeway. A statistical median is in the center of the data values.

Slope of a Line

The slope of a line is an algebraic concept used to graph linear equations. In the equation y = mx + b, the variable m represents the slope of the line. Slope is calculated by dividing the change in the y-coordinate (the rise) by the change in the x-coordinate (the run). Parallel lines have equivalent slopes. Perpendicular lines have slopes that are negative and reciprocal of each other. To graph a line when the slope and the y-intercept are known, plot the y-intercept and then use the slope to count UP and OVER to find another point on the line.

Addition of Integers

The RULE for adding integers is:<div>    If the signs are the same, add the absolute values of the numbers and give the result their same sign. If the signs are different, subtract the absolute values of the numbers and give them the same sign as the number with the larger absolute value. </div>

Division of Integers

The RULE for dividing integers is: If the signs are the same, divide the absolute values of the numbers and give the result a positive sign. If the signs are different, divide the absolute values of the numbers and give the result a negative sign.

What are tides?

World War 2

World War II was a major global conflict that lasted from 1939-1945. WWII was between Allied (USSR, US, UK, China, France, ...) and Axis (Germany, Japan, Italy, and affiliates) powers, and spanned across every continent (except Antarctica) at some point. WWII began on September 1, 1939 when Nazi Germany (a.k.a. the Third Reich) invaded Poland. Japan, as well, was invading other territories in Southwest Asia. At the zenith of the war, Germany had control over much of Central Europe, and was sending Jews, Poles, homosexuals, and other "inadequate" people to concentration and extermination camps (see "The Holocaust"). WWII also introduced new styles of warfare, including widespread air strikes and tank warfare, both of which were undeniably dominated by Germany. However, Germany's resources began to run short as Allied forces began to capture and liberate the concentration camps. Eventually, the Third Reich, along with Japan and Italy, collapsed. As a result of WWI and WWII, the UN was made, along with the establishment of Israel.

begin as huge clouds of dust and particles, called nebulas. all the particles in the nebulas are exerting gravitational force on all the other particles in the nebula over a long period of time, maybe millions of years, the gas and dust are pulled together, gravitationally, into the middle of the nebula *(this is called the nebula contracting)*, where they collide with each other and this collision ignites a huge nuclear (fusion) reaction. The nuclear reaction *a fusion reaction* creates a protostar, which eventually becomes a star After protostar is created, converts materials into denser and denser materials through fusion --getting denser and denser, and eventually converts into adult star

magnetism

can cause changes in motion *Outer Core of the Earth is *liquid molten metal* and as the Earth spins, the flow of the molten metal builds up a magnetic field around the Earth* Causes the Aurora Borealis because the Earth's magnetic field catches ions and particles coming into Earth's atmosphere and brings them down at the Earth's poles. The glowing lights are caused by charged particles (ions) coming down at the North Pole. Is also why a compass points North

Solar system

everything that surrounds a star all of the bodies that are orbiting that star are held in their paths by centrifugal force the balance between inertia and gravity in makes it want to continue in a straight line on into infinity gravity makes it want to go directly into the sun inertia vs gravity is like a tetherball. gravity is like the rope, the inertia is like hitting the ball and the sun is the pole

What is the prevailing theory on how the earth formed?

formed from the dust and gas that existed in the solar nebula, the gas and dust from which was pulled together by gravity. That gas and dust banged together in the center and ignited a large nuclear reaction, which created a protostar, which would eventually become a star, our sun. Little whirlpools of gas and dust also formed inside the nebula, further away from the center, these became the planets. This happened about 4.5 billion years ago. There was no life on Earth until about 3.8 billion years ago.

Absolute Value

Absolute value is the value portion of a number without a sign. Absolute values are also described as the distance on a number line from 0. Zero is the only number that is its own absolute value (because zero is neither positive nor negative).    See the flashcard on the "Properties of Absolute Value." <div> </div>

Approximating Square Roots

Approximating square roots means to find the approximate value of a number's square root. We find approximate square roots by comparing the number to perfect square numbers where the square roots are known.<div> </div><div>For example, to find the approximate square root of 51, use the fact that 7 x 7 = 49 and 8 x 8 = 64. Since 51 is between the perfect squares of 49 and 64 (but closer to 49 than 64), the approximate square root of 51 is between 7 and 8 (but closer to 7 than 8). The approximate square root of 51 is 7.1 or 7.2</div>

Multiples

A *multiple* is the product of the number and the counting numbers (1-9) any quantity and an integer. Multiples may be found by counting by the number. A calculator may also be used to find multiples - enter the quantity, hit the plus sign, enter the quantity again, and then hit the equal symbol. Then keep hitting the equal symbol to see successive multiples. Example: Find Multiples of 23: 23 + 23 = 46, = 69, = 92, = 115, etc. 23 x 1, 23 x 2, 23 x 3, 23 x 4, 23 x 5, etc.

Input and output are represented by parallelograms. Other symbols are used in more complex flow charts.

Frequency Distribution

A frequency distribution is an organized way to display the results from an experiment. Frequency distribution tables are often used in probability for situations that do not use sample spaces (a set listing ALL possible outcomes in an experiment).  The three types of probabilities are classical, empirical, and subjective. The probability for situations that use a frequency distribution is called Empirical Probability or Relative Frequency Probability. Classical probability uses a list of ALL possible outcomes. Subjective probability is based on a person's knowledge of the situation (an educated guess).

equilibrium

A condition in which all influences/forces acting on an object cancel each other out, so that a static or balanced situation results. -object is at rest -object is in state of uniform motion (constant speed/constant distance) -no *resultant force* (aka "net force") on the object (no one force stronger than any other and able to pull object) *acceleration = 0* ex: man doing a headstand - he is pushing his body up with an equal amount of muscle force that gravity is pulling his body down ex2: string with a weight tied to the end. Gravity pulls string down while the string pulls the weight up. These two forces are equal and opposite to each other. Together, they cancel each other out. The weight is "at rest" with no net forces acting on it.

A mixed number indicates the whole amounts and the parts (a fraction). For each whole number, there are a complete number of parts (for example, if the parts are measured in thirds, each whole has three thirds). To convert a mixed number to an improper fraction, multiply the whole number by how many parts are in a whole, and then add the remaining parts. For example, 6 2/3 means there are 6 whole amounts of 3/3 (6 x 3 = 18) so there are 18/3. Adding the remaining 2/3 results in a total of 20/3 in 6 2/3.

Why do compasses point north?

Earth behaves like a giant bar magnet with one pole up in the Arctic (near the north pole) and another pole down in Antarctica (near the south pole). Needle in compass is being attracted something near Earth's north pole. Since unlike poles attract, the thing your compass is being attracted to must be a magnetic south pole. In other words, the thing we call Earth's magnetic north pole is actually the south pole of the magnet inside Earth. That's quite a confusing idea, but it'll make sense if you always remember that unlike poles attract.

How can electricity be generated and used to power a lightbulb?

Elec. generated when something spins a generator. >magnet inside the generator rotates, causes electrons to build up, builds a charge on the coil in the generator > electrons want to "ground out" (aka bond with other atoms) > when given a path along a good conductor such as copper wire, electrons will follow wire > put light bulb along wire, in lightbulb put filament made of very resistant metal like tungsten. (Resistant means electrons really have to push to get through it which creates lots of friction, which turns to heat and makes the wire glow, which creates light) > then electrons go back out on the neutral wire to ground out *when filament heats up and starts glowing, converts electrical energy to light energy*

The ground pushes against him and the skateboard to propel him forward. ex3: Person sitting in a chair. Action force: Gravity pulling person down so doesn't float into air. Reaction force: person in the chair is exerting force of their mass onto the Earth, and the chair, which is applying an upward force on the person to keep them from falling through to the ground. ex4: ballon that is not tied - let go of balloon, air goes one way, the balloon flies the other way

The Sieve of Eratosthenes is a technique to teach young children about prime numbers. A paper is numbered from 2-100. Circle 2 because it is prime. Then count every 2 numbers and cross them off (cross off the multiples of 2). The next number after 2 that is not crossed off is 3, circle it. Count every 3 numbers (multiples of 3) and cross them off. The next number after 3 that is not crossed off is 5, circle it. Count the multiples of 5 and cross them off.... This process continues for the entire chart. All crossed-off numbers are composite; the prime numbers are circled.

Why is the ocean salty?

The ocean does not have drainage. Rivers, streams, etc. all feed INTO the oceans, bringing salt with them. But only way water LEAVES the ocean is by evaporation, which leaves the salt behind. Therefore, the ocean has no way to get rid of the salt

Solving Linear Equations

To solve a linear equation, isolate the variable. Apply the addition principle of equality (add the same number to both sides of the equation), and then apply the multiplication principle of equality (multiply the same number to both sides of the equation).

How is the *doppler effect* used to track weather systems?

Using a *doppler radar* -an inaudible sound/radio wave big enough to interact with clouds and other atmospheric objects is sent out -wave hit clouds/objects and bounce back to the receiver -if the sound wave comes back with exactly the same frequency, the cloud is not moving -if comes back with a *higher* frequency, cloud is moving *towards receiver* if comes back with a *lower* frequency, cloud is moving *away from receiver* -Based on the amount of the change in frequency (doppler shift), the speed of the object can be determined -computers in the doppler radar convert Doppler shift data about the reflected radio waves into pictures showing wind speeds and direction.

When the Moon is at its farthest distance from Earth

neap tides

When the Sun and the Moon are perpendicular to each other (in relation to the Earth) -happens during the First Quarter Moon or Third Quarter Moon -then high tides are not as high as they normally would be. This is because despite its greater distance, the Sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the Moon's pull. (Because the Earth rotates, the places of high/low tides will change as the Earth spins. Every 24 hours, a place will have 2 high tides and 2 low tides) http://www.moonconnection.com/tides.phtml

Solving Algebraic Word Problems (involving commissions)

When we think of sales commissions, we often think of car sales. Thus, it is appropriate that the formula for commission is C = ar, where C = commission earned, a = amount of sale, and r = commission rate. Example: Juana sells cars on a 3% commission rate. She just sold a car for $23,500. What was her commission? C = ar C = 23500(.03) C = $705

*Test Tip* Fraction Number Lines (Ruler)

When working with fractional number line, like a ruler, where you have to measure between point A and point B, don't do the complicated calculations, just count the number of 1/8ths or 1/16th between the points. Count the number of increments in each inch, that number is the denominator. Then count how many of those increments is between points A and B. That number is your numerator. Simplify if you can. Ex: 11/16th Ex2: 2/8ths = 1/4

Why do the boiling and freezing points of water change at different altitudes?

because of (atmospheric) pressure (at sea level, boiling: 212°F, freezing: 32°F) If you go *up* 10,000 ft in altitude, you have 10,000 *less feet of atmosphere pushing down on you*, so water might boil at 210°F, for example

Why can UV rays be damaging to us while longer wavelengths like radio waves pass right through us with no damage done?

because shorter wavelengths with higher frequency are more likely to collide with our other molecules (skin molecules, etc.) when these collisions happen, damage is done to our molecules radio waves are long enough to go between our other molecules without colliding with them

Why can't you hear in space?

calories in food are actually kilocalories. 1 kilocalorie = 1000 calories real calories measure energy (capacity to do work)

Why do certain areas experience more earthquake damage than others?

can depend on how hard the ground is -when goes through softer material, earthquake increases amplitude (goes up and down harder) and causes more damage Ex: San Francisco earthquake was worse along the shore line because ground there was more sediment and sandy in-fill (harder ground allows waves to pass through)

Energy

capacity to do work measured in calories (calories in food are actually kilocalories, which are 1000 of what physicists call calories)

How are tides created?

caused by the gravitational pull of the moon and sun on the Earth the moon has a stronger gravitational pull on the Earth than the Sun (because it's so much closer) Earth bends a little towards the moon because of this. Even the solid parts of the Earth do this, but of course, the liquid parts can really bend toward the moon because able to move more. So the oceans rise up towards the moon on the side that the moon is on AND on the other side, because there is LESS gravitational pull on that side, so those liquid parts are rising up AWAY from the moon. Two high areas and two low areas http://www.moonconnection.com/tides.phtml

Why do different bodies of water have different levels of salinity?

depends on how water enters/leaves the body of water bodies of water with drainage such as streams or rivers are much less salty because when the water leaves the body of water, it takes the salt with it bodies of water without drainage have no way to get rid of salt. water flows IN with salt, but can only EXIT by evaporation, when water evaporates, it leaves the salt behind, so water gets more and more salty This is also why the ocean is salty

Seasons are caused by

the Earth's tilt on its axis, the tilt itself does not change, the Earth tilts toward the right, so the top of the Earth is the right most point, if you were looking at it in a picture. Even though the tilt itself does not change, which part of the Earth is closest to the Sun changes based on where the Earth is in its orbit. (see picture) As the Earth revolves around the Sun, the tilt causes different hemispheres to receive more direct exposure at different times in its orbit (=diff times of the year)

Properties of Number System Operations

"Properties of Number System Operations <img src=""pastehp_zce.png"" />"

Decimal Number Division

"Division is not defined for decimal numbers. In order to divide by a decimal number, we change that divisor into a whole number: First multiply each number by powers of 10 - multiply by whatever is necessary to make the divisor a whole number. Then divide as you would with whole numbers. Wherever the decimal point is in the dividend, it floats directly up to that position in the quotient (answer). <img src=""pastex0nanh.png"" />"

Ordering Whole Numbers

"When you are asked to order whole numbers, write them above one another with the place values lined up. Then, starting from the *left*, look for the largest value. For example, if you are asked to order: 5,139 986,733 3,950 77,922 Write them above each other with the place values lined up as you would if you were going to add the numbers. Looking at the place values from left to right, the largest number is 986,733. The next largest number is 77,922. Both the first and third numbers start in the same place value but 5 is larger than 3 so 5,139 is larger than 3,950

Division of Fractions & Mixed Numbers

*Division of Fractions & Mixed Numbers: is not defined.* As such, we use the properties of our number system to *change the division problem into a multiplication problem*, which *is* defined. (see pic) -Change mixed numbers to improper fractions. -Change whole numbers to improper fractions with a "1" on the denominator. -Write the two fractions horizontally beside each other. -Write the reciprocal of the divisor (flip the second fraction upside down) and change the operation to multiplication. Expand each numerator and each denominator into a prime factorization. "Cancel" any ones such as 3/3 or 5/5. Multiply what is left straight across. A reciprocal is the inverse of a fraction. Multiplication is the inverse of division. The inverse of an inverse is the same as the original problem. As such, multiplication of a reciprocal is the same as dividing by the original divisor. *Remember on test, if answers are in fraction form, correct answer will always be reduced* *Do NOT need common denominators* *Answer should be MORE than the original factors* (ex: ½ ÷ ¼= 4/2 = 2) <--2 is more than 1/2 or 1/4*

Equivalent Fractions

*Equivalent fractions* are fractions which simplify to the same simple fraction When two fractions are equivalent, their cross products are equal (see picture) If have a variable, cross multiply to solve. (Each side will now be a linear equation, no longer in fraction form. See example) ex: x/9 = 12/54 54x= (9)(12) 54x= 108 (54x)÷54 = 108÷54 x=2 *Remember on test, if answers are in fraction form, correct answer will always be reduced*

LCM

*Lowest Common Multiple (LCM)* of two or more numbers is the smallest number that is a multiple of all the numbers. One way to find the LCM is to count by each of the numbers and find the first number that is a multiple of all. For example, find the LCM of 9, 12, and 18 Then make a Venn Diagram with all the factors, the shared factors in the center. Lastly, multiply all the numbers together. This is the LCM. (see pic) example LCM word problem: One day, Edward and his friends had lunch while sitting at tables of 15. Another day, they had lunch at tables of 10. What is the *smallest number of people that could be in the group?* (30 people)

Simplifying Fractions

*Simplifying fractions* is sometimes (incorrectly) called reducing a fraction. Expand the numerator and denominator into prime factorizations (see pic). "Cancel" any ones such as 3/3 or 5/5. Then multiply straight across those numbers that are left. The resulting (simplified) fraction is equivalent to the original fraction but is in simplified form. *Remember on test, if answers are in fraction form, correct answer will always be reduced*

First 10 Square Numbers

1, 4, 9, 16, 25, 36, 49, 64, 81, 100

Divisibility Rules

2= Even numbers (ending in 0, 2, 4, 6, and 8) 3 = If repeated sums of the digits result in 3, 6, or 9 4 = If the last two digits are divisible by 4 5 = If the last digit is 0 or 5 6 = If the number is divisible by both 2 and 3 8 = If the last three digits are divisible by 8 9 = If repeated sums of the digits result in 9 10 = If the last digit is 0

Which equation shows the commutative property of addition? 2+3 = 4+1 8+1 = 1+8 7+2 = 9

8+1 = 1+ 8 move numbers around and they mean the same thing *THINK COMMUTE = move The property that says that two or more numbers can be added or multiplied in any order without changing the result.

Decimal Number Addition

Decimal numbers are added exactly the same as whole numbers: line up the numbers by place value and add each place value from the right to the left. When the decimal numbers are lined up by place value properly, the decimal points in each number are also lined up. Any number without a decimal point is lined up so the ones place is right before the decimal point (there is an understood decimal point after the one's place). It may help to write zeros in empty places to facilitate addition.

Decimal Number Multiplication

Decimal numbers are multiplied by temporarily ignoring the decimal point. Multiply the two numbers as though they were whole numbers. In the final product, place the decimal point to signify the number of decimal places in both numbers of the original problem. For example:  2.3 (one decimal place) x 1.456 (three decimal places) is the same as 23 x 1456 with the answer having four decimal places (1 + 3 from the original problem) Technically, decimal numbers are multiplied by powers of 10 in order to make them whole numbers before multiplication. Then the answer (product) is divided by that same power of 10.

Fractions (Definition, Meaning, and Parts)

A *fraction* represents equal-sized parts of a whole. The top number of a fraction is called the *numerator* because it is the number of parts. The *denominator* is a denominate number (measurement of size) telling how many of the equal-sized parts are in the whole. The line between the numerator and denominator indicates division and is called a *vinculum* Note that the parts MUST be equal-sized. The parts are usually indicated by coloring them or shading them *Remember on test, if answers are in fraction form, correct answer will always be reduced*

Prime Factorization

A *prime factorization* of a number is a list of all prime factors that multiply together to make that number. A factor tree is often used to find the prime factorization of a number. The prime factorization can be written as the product of individual factors or exponents can be used to write the product of repeated prime factors. Ex: 120 = 2 x 2 x 2 x 3 x 5 This can also be written as 120 = 23 x 3 x 5

Ratios (Definition & three ways to write)

A *ratio* is a FIXED relationship between 2 quantities, or in other words, are a comparison of 2 numbers using division. The most common ratios we see are fractions. Write a ratio using a fraction bar, a colon, or the word "to": 3:2 3/2 3 to 2 When we *set two ratios equal to each other,* we say these 2 ratios/fractions are *proportionate.* The comparison between the numerators and the denominators is *the same fixed relationship*. ex: 1/2 = 2/4 "One half is equal to two fourths." ="One half is proportionate to two fourths."

Factor Tree

A factor tree is a method used to find a number's prime factorization. Start by splitting the number into any two factors that multiply to make that number. Then split each of those two factors into two factors each. Keep splitting each "branch" of the factor tree until you reach a prime number, which cannot be split into factors. The final prime numbers at the end of each "branch" of the factor tree are the prime factorization of the number. See pic for factor tree which shows that the prime factorization of 120 = 2 x 2 x 2 x 3 x 5

Whole Number Place Value

A number in standard form is marked into groups of three digits using commas. Each of these groups is called a period. Within each group, the place values are always the 100's place, the 10's place, and the 1's place (from left to right). Understanding place value is key to understanding our number system. Decimal numbers simply extend the place values to the right and use "ths" to identify the places (e.g. 100 millionths place).

Rectangular Solid (Definition, volume, and surface area)

A rectangular solid (also known as a cuboid) is a three-dimensional solid where *all angles are right angles* and *opposite faces are equal.* A rectangular solid is also informally called a rectangular box. V = Lwh SA = 2wh + 2hL + 2wL

diameter

A straight line passing from side to side through the center of a circle or sphere. It is radius * 2 d=2r

Proportions (Definition)

A true statement that two ratios or fractions are equal. If have a variable, cross multiply to solve. (Each side will now be a linear equation, no longer in fraction form. See example) ex: x/9 = 12/54 54x= (9)(12) 54x= 108 (54x)÷54 = 108÷54 x=2 Every proportion is made up of 4 numbers. When we *set two ratios equal to each other,* we say these 2 ratios/fractions are *proportionate.* The comparison between the numerators and the denominators is *the same fixed relationship*. ex: 1/2 = 2/4 "One half is equal to two fourths." ="One half is proportionate to two fourths."

Irrational Numbers

All real numbers except the rational numbers; -numbers that are square roots of non-perfect square numbers -non-terminating, non-repeating decimal s (like pi - just keeps going no end) -most well-known irrational number is pi (π) which is approximately equal to 22/7 or 3.14 The opposite of Irrational numbers are the rational numbers - ALL real numbers are either rational or irrational.

Improper Fraction & Mixed Numbers (Definition)

An *improper fraction* has a numerator larger than (or equal to) the denominator and indicates a fraction that is equal to one or more than one whole An improper fraction can be changed into a whole number or a mixed number by dividing the denominator into the numerator. A mixed number is the sum of a non-zero integer and a proper fraction. *Remember on test, if answers are in fraction form, correct answer will always be reduced* *Improper fractions: denominator might not be most simplified one - make into mixed number THEN SIMPLIFY FURTHER*

Rational Numbers

Any number that can be represented as the RATIO of two INTEGERS (integers are the counting numbers, their negatives, and zero (..., -3, -2, -1, 0, 1, 2, 3 ...).) -integers (because every integer is the ratio of the integer over 1. ex: 2 = 2/1) -fractions -decimals that end (like 12.5) or repeat the same numbers over and over (like 23.666666) -percentages **Square roots of non-perfect squares can NOT be expressed as the fraction of two integers, so they IRrational numbers* All real numbers are either rational or irrational. Sets in mathematics include the set of integers (Z), rational numbers (Q), primes (P), real numbers (R), natural numbers (N), whole numbers (W), etc.

Converting Percentages to Decimals & Fractions

Change a percent to a decimal by moving the decimal point two places to the left and removing the percent sign: 14% = 0.14 Change a percent to a fraction by writing the percent as a fraction over 100 and simplifying: 14% = 14/100, which simplifies to 7/50 *Remember: per = divided by; cent = 100* *On test, all fractions must be in most simplified version*

Classify Numbers in Real Number System

Classify Numbers in Real Number System Sets in mathematics include the set of integers (Z), rational numbers (Q), primes (P), real numbers (R), natural numbers (N), whole numbers (W), etc.

solve multi-step mathematical and real-world problems using division of rational numbers DIVIDING FRACTIONS

Flip the 2nd fraction upside down, then multiply straight across, then simplify answer *If numerator and denominator are both divisible by the 2nd number, can just divide across* ex: (2/3) ÷ (3/4) = (2/3) * (4/3) = (2*4) / (3*3) = (8/9) cannot divide 2 by 3, so cannot divide across in this problem ex2: 2/3 ÷ 5 Make the whole number into fraction: = 2/3 ÷ 5/1 INVERT the 2nd fraction: =2/3 * 1/5 MULTIPLY ACROSS: =(2*1)/(3*5) =2/15 cannot divide 2 by 5, so cannot divide across in this problem ex3: 3 ÷ 1/4 INVERT the 2nd Fraction: = 3/1 ÷ 1/4 Multiply across: =3/1 * 4/1 = (3*4)/(1*1) =12/1 SIMPLIFY = 12 ex4: 8/10 ÷ 2/5 = ? INVERT the 2nd Fraction: =8/10 * 5/2 = ? Multiply across: (8*5)/(10*2) = ? Simplify (40) / (20) = ? 4/2 =2 On this one, the numerator and denominator are both divisible by the 2nd number, so could also just divide across 8/10 ÷ 2/5 = (8÷2)/(10÷5) = 4/2 = 2 (*When you flip the 2nd fraction upside down, it is called the RECIPROCAL of the 2nd fraction, or INVERTING the 2nd fraction) ♫ "Dividing fractions, as easy as pie, Flip the second fraction, then multiply. And don't forget to simplify!" ♫

Imaginary Numbers

Imaginary Numbers are numbers that contain the imaginary number "i", which is the square root of negative one: Note that if the discriminant portion of the quadratic equation is negative, the function or quadratic equation has no real solutions.

solve multi-step mathematical and real-world problems using addition of rational numbers ADDING FRACTIONS

Step 1: Find common denominator -multiply each fraction (both top and bottom) by the denominator of the other fraction - we can do this because any fraction with the same number on the top and bottom is equal to 1, so we are really just multiplying by 1 (look at picture to understand better) Step 2: Add numerators (tops), put the answer over the denominator Step 3: Simplify the fraction (if needed) ex: ¼ + ¼= 2/4 ex2: 1/3 + 1/6 = (6/6) (1/3) + (3/3)(1/6) = (6/18) + (3/18) = 9/18 =1/2

GCF

The *Greatest Common Factor* (GCF) of two or more numbers is the *largest number that is a factor of all the numbers.* One way to find the GCF is to write the prime factorization of each of the numbers. Then make a Venn Diagram with all the factors, the shared factors in the center. Lastly, multiply all the numbers in the middle of the Venn diagram together. (see pic) example GCF word problem: Mei is a dental sales representative who wants to distribute 16 brochures and 10 pamphlets to local dental offices. She wants to deliver *the same combination* of brochures and pamphlets *to each* office, *without having any materials left over.* What is the *greatest number* of dental offices Mei can distribute materials to?
