HESI A2 Math Practice Test 2024

Correct Answer: C

Rationale: To find the perimeter of the kite, we add up all the sides. Top base = 20cm Bottom base = 30cm Two equal side lengths = 15cm each Perimeter = 20 + 30 + 15 + 15 = 80cm Therefore, the correct answer is C (70cm). Choice A (55cm) is incorrect as it does not consider all the sides of the kite. Choice B (65cm) is incorrect as it does not account for the top and bottom bases. Choice D (80cm) is incorrect as it miscalculates the perimeter by not adding the side lengths correctly.

Correct Answer: A

Rationale: To find the value of x, we can use the concept of proportional relationships. The ratio x:15 is equal to 120:225. To solve for x, we can set up a proportion equation: x/15 = 120/225. Cross multiply to get x = 15 * 120 / 225 = 8. Therefore, the correct answer is A: x=8. Summary: - Choice A is correct because it was derived from setting up and solving the proportion equation correctly. - Choices B, C, and D are incorrect because they do not match the solution obtained through the proportion equation.

Correct Answer: B

Rationale: To change a percentage to a decimal, you divide by 100. In this case, 0.03% divided by 100 equals 0.0003. Therefore, the correct answer is B. Choice A (0.03) is the original percentage value without conversion. Choice C (0.3) is 10 times the correct answer. Choice D (0.003) is 10 times smaller than the correct answer.

Correct Answer: A

Rationale: To find x in the proportion 6:10=24:x, we first calculate the ratio of the given numbers, 6/10=24/x. Simplifying, we get 0.6=24/x. Cross multiplying, we get x=24/0.6=40. Therefore, the correct answer is A. Choice B is incorrect as it does not satisfy the proportion. Choice C is incorrect as it is too large compared to the correct answer. Choice D is incorrect as it is too small compared to the correct answer.

Correct Answer: B

Rationale: The military time 15:17:52 is equivalent to 3:17:52 PM in regular time. To convert from military time to regular time, we subtract 12 from the hour if it is greater than 12 to get the PM time. Therefore, 15 - 12 = 3, indicating it's in the afternoon. The correct answer is B (3:17 PM). Choice A (2:17 PM) is incorrect because 15 is greater than 12, so it would be in the afternoon. Choice C (5:17 AM) is incorrect because 15 is in the afternoon, not morning. Choice D (9:17 AM) is incorrect because 15 is in the afternoon, not morning.
