TEAS 7 Math Practice Test

Correct Answer: B

Rationale: To calculate the number of tanks Robert needs, we divide the total distance by the car's mileage per tank: 1800 miles / 30 miles per gallon = 60 gallons needed. Since his tank holds 12 gallons, we divide the total gallons needed by the gallons per tank: 60 gallons / 12 gallons per tank = 5 tanks. Therefore, the correct answer is B: 5 tanks. Choice A (3 tanks) is incorrect because it doesn't consider the total distance. Choices C (30 tanks) and D (60 tanks) are incorrect as they grossly overestimate the number of tanks needed.

Correct Answer: A

Rationale: To find the number of respondents who use smartphones for email, we multiply the percentage (60%) by the total number of respondents (5,000). 60% of 5,000 = 0.60 * 5,000 = 3,000 respondents. Therefore, choice A (3,000 respondents) is the correct answer. Choices B, C, and D are incorrect because they do not reflect the correct calculation based on the given percentage and total number of respondents.

Correct Answer: B

Rationale: The correct answer is B (25). To find the range, subtract the smallest value from the largest value in a set of data. Given the options, 32 (largest) minus 7 (smallest) equals 25. Therefore, the range in the number of flights the flight attendant made is 25. Option A (20) is incorrect as it is smaller than the actual range. Option C (29) and D (32) are incorrect because they are larger than the actual range, making them invalid choices.

Correct Answer: B

Rationale: Correct Answer: B ($48,443) Rationale: To find the total price of Veronica's new car, add the base price ($40,210) to the cost of the surround sound system ($3,015) and the maintenance package ($5,218). Therefore, $40,210 + $3,015 + $5,218 = $48,443. Summary of other choices: A: $50,210 - Incorrect as it only includes the base price of the car. C: $43,225 - Incorrect as it only includes the base price and the maintenance package. D: $40,210 - Incorrect as it only includes the base price of the car.

Correct Answer: D

Rationale: The product of two even integers and one odd integer will always be an even integer. This is because multiplying any number of even integers together results in an even number, and multiplying any number of odd integers together also results in an odd number. Therefore, the product could not be 3.75 (odd), 9 (odd), or 16.2 (even non-integer). The only possible option is 24, as it is an even integer and can be obtained by multiplying two even integers and one odd integer together.
