Answer takes the sign of the bigger number

Circumference of a circle

C = π d

Improper Fractions to Mixed Numbers

Large number on top, Divide: 18/7 = 7√18 = 2 R4 or 2 4/7

Area of a square/rectangle

Cost with tax

Multiply % by price, add answer back to price; 6% sales tax on $13.00 = $13.00 x .06 = .78; $13.78

sales tax

Multiply % by price; 7% sales tax on $8.00 = $8.00 x .07 = .56

Down Payment

Multiply cost by % of down payment; 20% down payment on $300.00 = $60

Adding fractions with different denominators

Must rewrite with common denominator. 1/2 + 2/3 Lowest common denominator is 6. (2x3 = 6 for denominator, 1x3=3 for numerator) 1/2 = 3/6 (3x2 = 6 for the denominator, 2x2 = 4 for the numerator) 2/3 = 4/6 3/6 + 4/6 = 7/6 = (1 1/6)

slope

Rise over run

Order of fractions

Smallest bottom number is the largest fraction

perimeter

The distance around a figure, add all sides

Greatest Common Factor (GCF)

The largest factor that two or more numbers have in common; used to find denominators; GCF of 8 & 12 is 4

Square root

a number that when multiplied by itself equals a given number: square root of 49 = 7

Mixed fraction

a whole number and a fraction. Example 1 1/2

Adding fractions with common denominators

add the numerators, denominators stay the same

Pythagorean Theorem - Right Triangles

a²+b²=c²

Distance between two points

d = √(x₁-x₂)² + (y₁-y₂)²

How do you convert a mixed number to an improper fraction?

multiply the denominator by the whole number then add the answer to the numerator; 4 3/7 = 31/7
