TEAS MATH

*What is the missing number in the sequence: 4, 6, 10, 18, ___, 66.* 54 34 45 22

*34* Double the number that is added to the previous number. So, 4+2=6, 6+4=10, 10+8=18, 18+16=34, and 34+32=66.

*Multiply 2 1/7×3 2/3.* 1 1/3 7 6/7 1 32/45 4/7

*7 6/7* 2 1/7 × 3 2/3 = 15/7 × 11/3 = 165/21 = 7 18/21 = 7 6/7.

What does 68% equal? .0068 .68 6.8 6800

.68 68% = 68/100. To express as a fraction, move the decimal two places to the left, .68.

Convert 250 centimeters to kilometers. 2.50 km 0.025 km 0.250 km 0.0025 km

0.0025 km 1 kilometer is equal to 100,000 centimeters. 250/10000 = .0025.

The following items were purchased at the grocery store. What was the average price paid for the items? $0.34 $1.38 $0.55 $0.93

*$0.93* .6 Calculate the average price as [(3.5 × 2) + (0.3 × 5) + (1.25 × 3) + (0.45 × 6) ]/((2 + 5 + 3 + 6) ) = 0.93.

*Restaurant customers tip their server only 8 percent for poor service. If their tip was $3.70, how much was their bill?* $44.60 $40.15 $50.45 $46.25

*$46.25* Rationale: The total amount of the bill is: 3.70/x = 8/100; 370 = 8x; x = $46.25.

*A pasta salad was chilled in the refrigerator at 35° F overnight for 9 hours. The temperature of the pasta dish dropped from 86° F to 38° F. What was the average rate of cooling per hour?* (5.3°)/hr (0.532°)/hr (5.15°)/hr (4.8°)/hr

*(5.3°)/hr* The average rate of cooling is: ((86º - 38º))/9 hrs; (48º)/9 = 5.33º F per hour.

*If Leonard bought 2 packs of batteries for x amount of dollars, how many packs of batteries could he purchase for $5.00 at the same rate?* 10x 2x 10/x 2/x

*10/x* Solved: First set the relationship up and solve for the number of packs: x/2=5/packs; x(packs) = 10; packs = 10/x.

*Enrique weighs 5 pounds more than twice Brendan's weight. If their total weight is 225 pounds, how much does Enrique weigh?* 125 pounds 152 pounds 165 pounds 115 pounds

*152* Solved: Enrique is 5lbs more than twice Brendan weight = E= 2B+5 The total weight is 225....E+B=225 Plug in and Solve for B......(2B+5) + B= 225 B=73.33 Plug in the 73.33 and Solve for E E+(73.33)=225 E=152

*What does (4x - y) + (-10 + y) equal if x = 3 and y = 4?* 2 -2 22 14

*2* Plugging in x and y, you get (4(3) - 4) + (-10 + 4), which is 8 + (-6), or 8 - 6 = 2.

*If Sara can read 15 pages in 10 minutes, how long will it take her to read 45 pages?* 40 minutes 30 minutes 50 minutes 20 minutes

*30 minutes* Solve: 15pgs = 10mins so.........45pg= x mins 15pg/10min 45pg/x min Cross multiply........45(10)=450 Divide by 15...... 450/15=30

*Find (27/9) × (√(25) × 2).* 12 90 45 30

*30* Remember the order of operations: (27/9) = 3 and (√(25) × 2) = 10; 3 × 10 = 30.

*Loral received all her grades for the semester (in parentheses) along with the weight for each grade, shown below. What is her final grade?* *Weight* *45% = 3 tests (80%, 75%, 92%)* *25% = final (88%)* *15% = paper (91%)* *15% = 2 oral quizzes each worth 25 points (22, 19)* 85 88 86 79

*85* Calculate the weighted average of the 3 tests: ((80+75+92))/3 = 82.3; Calculate the average of the 2 oral quizzes: (22/25) ×100 = 88 and (19/25) × 100 = 76, so (88 + 76)/2 = 82. Multiply each grade by their weight, and then add them all up to determine the final grade: (82 × .45) + (88 × .25) + (91 × .15) + (82 × .15) = 85.

*Choose the algebraic expression that best represents the following situation: Jeral's test score (J) was 5 points higher than half of Kara's test score (K).* J = 2K - 5 K = 1/2 J - 5 K = (J - 1/2) - 5 J = 1/2 K + 5

*J = 1/2 K + 5* Jeral test score is *5 point more* (that means to add) than half (1/2) of kara's

*Which of the following is an improper fraction?* 2/3 1 3/5 5/2 2.50

5/2 An improper fraction is one whose numerator is greater than the denominator.
