HESI A2 Math Practice Test 2023

Correct Answer: C

Rationale: To find the total number of pages in the book, we multiply the number of chapters by the number of pages per chapter: 2 chapters/day * 6 pages/chapter = 12 pages/day. To finish 798 pages, we divide 798 pages by 12 pages/day, giving 66.5 days. Therefore, the correct answer is C: 66.5 days. Choice A (133 days) is incorrect because it assumes the man reads 1 chapter per day instead of 2. Choice B (399 days) is incorrect as it overestimates the number of days needed by assuming the man reads only 1 page per day. Choice D (75 days) is incorrect because it underestimates the time needed by assuming the man reads 3 chapters per day instead of 2.

Correct Answer: B

Rationale: To convert from kilograms to grams, you multiply by 1000 since 1 kilogram is equal to 1000 grams. So, 6 kilograms x 1000 = 6000 grams. Therefore, the correct answer is B: 6000 grams. Choice A (600 grams) is incorrect because it doesn't account for the conversion factor of 1000 between kilograms and grams. Choice C (600 grams) is also incorrect as it doesn't reflect the correct conversion. Choice D (60,000 grams) is incorrect as it misinterprets the conversion factor and multiplies incorrectly.

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: A

Rationale: To convert yards to inches, you need to know that 1 yard is equal to 36 inches. Therefore, 1.5 yards is 1.5 x 36 = 54 inches. The correct answer is A (54 inches). Choice B (60 inches) is incorrect because it does not accurately convert 1.5 yards to inches. Choices C (72 inches) and D (84 inches) are also incorrect as they do not reflect the correct conversion.

Correct Answer: D

Rationale: The correct answer is D: 64cm^2. To find the area of a rectangle, you multiply the length by the width. In this case, 5cm x 8cm = 40cm^2. Therefore, the bandage covers an area of 40cm^2. The other choices are incorrect because A (10cm) and B (13cm) are not calculations of the area, and C (40cm^2) is the result of multiplying the dimensions incorrectly. Hence, the correct answer is D as it accurately represents the area covered by the bandage.
