HESI A2 Math Practice Test 2023

Correct Answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, to convert 5 kilograms to grams, you would do: 5 kg x 1000 = 5000 grams. Choice C (5,000 grams) is the correct answer. Choice A (50,000 grams) and choice D (50,000 grams) are incorrect because they do not correctly convert the kilograms to grams. Choice B (500 grams) is incorrect because it represents the grams equivalent of 0.5 kilograms, not 5 kilograms.

Correct Answer: C

Rationale: To find the volume of a cone, we use the formula V = (1/3)πr^2h. Plugging in the values, V = (1/3)π(5)^2(12) = 100π ≈ 314.16 cu cm. Therefore, the correct answer is C (150 cu cm), as it is the closest option to the calculated volume. Option A is too small, B is slightly larger, and D is too large compared to the actual volume.

Correct Answer: D

Rationale: To solve for x in the equation 4x - 8 = 16, we first isolate x by adding 8 to both sides, yielding 4x = 24. Then, divide both sides by 4 to find x = 6. This is the correct answer because it satisfies the original equation. Choice A and B are the same and incorrect. Choice C is incorrect as it does not solve the equation correctly.

Correct Answer: A

Rationale: To determine the distance traveled by the train, we use the formula Distance = Speed x Time. Given the speed of 65 mph and time of 1.5 hours, we calculate 65 mph x 1.5 hours = 97.5 miles. Therefore, the correct answer is A: 97.5 miles. Option B, 100 miles, is incorrect as it does not match the calculated result. Options C and D, 98 miles and 95 miles, respectively, are also incorrect as they do not align with the calculated distance based on the given speed and time.

Correct Answer: B

Rationale: To convert kilograms to pounds, you multiply by 2.2. In this case, 75 kg x 2.2 = 165 pounds. Therefore, the correct answer is B: 150 pounds. Choice A is incorrect as it is less than the actual conversion. Choices C and D are also incorrect as they are significantly lower than the correct conversion.
