TEAS Math Practice Test

Correct Answer: B

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: A

Rationale: To find what number 20 is equal to 40% of, you divide 20 by 0.40 (40%). This gives 50, which is choice A. The correct answer is A because 20 is indeed 40% of 50. Choices B, C, and D are incorrect because 20 is not 40% of 8, 200, or 5000 respectively.

Correct Answer: C

Rationale: The correct answer is C: x = y^2. This equation does not represent a function because it fails the vertical line test, where any vertical line intersects the graph at more than one point. In this case, for each x value, there are two corresponding y values (positive and negative square roots), violating the definition of a function where each input can only have one unique output. Choices A, B, and D all represent functions as each x value corresponds to only one y value, satisfying the function criteria.

Correct Answer: B

Rationale: To convert miles to kilometers, we use the conversion factor: 1 mile = 1.60934 kilometers. Therefore, 4.67 miles is equal to 4.67 * 1.60934 = 7.504 km. Rounding to three significant digits gives us 7.51 km, which is the correct answer (B). Choice A (7.514 km) is incorrect as it has been rounded to four significant digits. Choice C (2.90 km) and choice D (2.902 km) are incorrect as they are much smaller values due to incorrect calculations or rounding.

Correct Answer: A

Rationale: To divide 52 by 27, we get 1 with a remainder of 25. Then, when we divide 51 by 27, we get 1 with a remainder of 24. Therefore, the correct answer is A: 52/27, as it represents the result of the division without simplification. Choices B, C, and D are incorrect as they do not accurately represent the division results obtained.
