Math HESI A2 Practice Test

Correct Answer: C

Rationale: To find the total words typed in 20 minutes, multiply words per minute by minutes: 45 words/minute x 20 minutes = 900 words. Thus, the correct answer is C (900 words). A is incorrect as it miscalculates the total. B is incorrect as it underestimates the total. D is incorrect as it duplicates option A.

Correct Answer: A

Rationale: To find the distance traveled, we first calculate the time elapsed from 1:45 PM to 3:15 PM, which is 1.5 hours. Next, we multiply the speed of 65 mph by the time of 1.5 hours to get the distance traveled, which equals 97.5 miles. Therefore, the correct answer is A: 97.5 miles. Choice B (100 miles) is incorrect because the calculation does not result in 100 miles. Choice C (95 miles) is incorrect as it is less than the correct distance. Choice D (105 miles) is incorrect as it is greater than the correct distance calculated.

Correct Answer: D

Rationale: To convert kilograms to grams, we need to multiply by 1000 since there are 1000 grams in a kilogram. So, 8 kilograms x 1000 = 8000 grams. Therefore, the correct answer is D: 8000 grams. Choice A (80000 grams) is incorrect as it incorrectly multiplies by 100 instead of 1000. Choice B (800 grams) is incorrect as it is the result if we ignore the conversion factor. Choice C (80000 grams) is a duplication of choice A.

Correct Answer: A

Rationale: To subtract 9.99 from 12.02, we need to align the decimal points. 12.02 minus 9.99 equals 2.03. So, the correct answer is A. Choice B, 2.21, is the result of adding the numbers. Choice C, 3.17, is the result of adding 9.99 and 2.03. Choice D, 7.97, is the result of subtracting 12.02 from 9.99.

Correct Answer: A

Rationale: To divide 5 3/4 by 1/2, we convert 5 3/4 to an improper fraction as 23/4. Then, we divide 23/4 by 1/2, which is equivalent to multiplying by the reciprocal of 1/2, which is 2. Therefore, 23/4 * 2 = 46/4 = 11 1/2. The correct answer is A. Other choices are incorrect as they do not result from the correct calculation process.
