TEAS Test Math Questions

Correct Answer: A

Rationale: To convert liters to kiloliters, we divide by 1000 since 1 kiloliter is equal to 1000 liters. In this case, 147 liters divided by 1000 equals 0.147 kiloliters, so the correct answer is A. Choice B is 10 times the correct answer, choice C is 100 times the correct answer, and choice D is 1000 times the correct answer, making them incorrect.

Correct Answer: D

Rationale: To find the area of a circle, we use the formula A = πr^2, where r is the radius. Since the diameter is 16 cm, the radius is half of that, which is 8 cm. Plugging this into the formula, A = 3.14 * 8^2 = 3.14 * 64 = 200.96 cm^2. Therefore, the correct answer is D. Choice A: 25.12 - This is incorrect as it is much smaller than the correct answer. Choice B: 50.24 - This is incorrect as it is also smaller than the correct answer. Choice C: 100.48 - This is incorrect as it is still smaller than the correct answer.

Correct Answer: B

Rationale: To find the sum of 4 + 5 + 12 + 9, we add each number sequentially: 4 + 5 = 9 9 + 12 = 21 21 + 9 = 30 Therefore, the correct answer is B: 30. Option A (20), C (40), and D (50) are incorrect as they do not accurately reflect the sum of the given numbers.

Correct Answer: A

Rationale: To find the total distance Jayden rides, add the two distances: 5/8 + 3/4 = 10/16 + 12/16 = 22/16 = 1 6/16 = 1 3/8 miles. Therefore, choice A (1 3/8 miles) is the correct answer. Choices B, C, and D are incorrect because they do not accurately calculate the total distance Jayden rides based on the given distances.

Correct Answer: D

Rationale: To find the rate of change in height per month, we multiply the daily growth rate by the number of days in a month. 4.2 inches/day * 30 days = 126 inches/month. Therefore, the correct answer is D. Choice A is incorrect as it is the daily growth rate, not the monthly rate. Choice B is incorrect as it is the same as the daily growth rate, not the monthly rate. Choice C is incorrect as it is not the result of the correct calculation.
