TEAS Test Sample Math Questions

Correct Answer: D

Rationale: To write 0.80 as a percent, you multiply it by 100. So, 0.80 * 100 = 80%. Therefore, the correct answer is D. Choice A (40%) is incorrect because 0.80 is not equivalent to 40%. Choice B (125%) is incorrect as 0.80 is less than 100%. Choice C (90%) is incorrect because 0.80 is not equal to 90%.

Correct Answer: A

Rationale: To divide fractions, we multiply the first fraction by the reciprocal of the second. So, (4/3) ÷ (9/13) = (4/3) x (13/9) = 52/27. The correct answer is A, 52/27, as it follows the correct procedure of dividing fractions. The other choices are incorrect because they do not result from the proper operation of dividing fractions.

Correct Answer: D

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: A

Rationale: The correct answer is A: All real numbers. The function f(x)=2x+5 is a linear function, which means it is defined for all real numbers. There are no restrictions on the input x, so the domain includes all real numbers. Choices B, C, and D are incorrect because they impose restrictions on the domain that are not present in the given function. Choice B limits x to be greater than or equal to 0, choice C limits x to be strictly greater than 0, and choice D limits x to be less than or equal to 0, all of which are not accurate for the function f(x)=2x+5.

Correct Answer: B

Rationale: To find the sum of 0.75 and 0.625, you add the two numbers together: 0.75 + 0.625 = 1.375. Therefore, the correct answer is B. Choice A (0.875) is incorrect because it is the sum of 0.75 and 0.125. Choice C (1.625) is incorrect because it is the sum of 0.75 and 0.875. Choice D (0.125) is incorrect as it is the sum of 0.75 and -0.625.
