HESI A2 Math Practice Test 2023

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.

Correct Answer: D

Rationale: To convert ounces to pounds, we know that 1 pound is equal to 16 ounces. Therefore, to find how many pounds are in 144 ounces, we divide 144 by 16, which equals 9 pounds. The correct answer is D. Incorrect Answers: A: 12 pounds - Incorrect because 144 ounces is not equivalent to 12 pounds. B: 10 pounds - Incorrect, as 144 ounces do not convert to 10 pounds. C: 8 pounds - Incorrect, as 144 ounces do not equate to 8 pounds.

Correct Answer: B

Rationale: To subtract 14.5 - 7.25, align the decimals and perform subtraction. Starting from the right, subtract 5 from 0 (borrow 1 from 4), giving 5. Then, subtract 2 from 4, giving 2. The correct answer is 7.25. Other choices are incorrect because they do not match the result obtained from the subtraction process. Choice A and C are too small, while choice D is too large.

Correct Answer: A

Rationale: The correct answer is A: 5.3 hours. To calculate the total time taken, add the time taken for each set of 6 miles: 1 hour + 1.2 hours + 1.5 hours + 1.6 hours = 5.3 hours. This is the total time taken by the female to complete the 24-mile course. Choice B (4.5 hours) is incorrect because it does not account for the increasing time taken for each set of 6 miles. Choice C (6 hours) is incorrect as it assumes each set of 6 miles took the same amount of time, which is not the case. Choice D (7 hours) is incorrect as it overestimates the total time taken.

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.
