HESI A2 Math Practice Test 2023

Correct Answer: B

Rationale: To find 80% of 55, you multiply 55 by 0.8 (which is the decimal equivalent of 80%). So, 55 * 0.8 = 44. Therefore, the correct answer is B (44). Choice A (40) is incorrect as it represents 80% of 50, not 55. Choices C (39) and D (45) are also incorrect calculations.

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: A

Rationale: To determine the largest fraction, we need to find a common denominator. In this case, we can convert all fractions to have a denominator of 56. 3/7 = 24/56 3/6 = 28/56 3/9 = 21/56 3/8 = 21/56 Comparing the numerators, 28/56 is the largest, so the correct answer is 3/6 or option B. Option A (3/7) is incorrect as it is smaller than 3/6 when both are converted to a common denominator. Options C and D are also incorrect as they are smaller than option B.

Correct Answer: B

Rationale: To find the perimeter of the table, we add the lengths of all four sides. Since opposite sides are equal, we have two pairs of sides with lengths 75cm and 50cm each. Therefore, the perimeter is 2(75cm) + 2(50cm) = 150cm. Choice A is incorrect because it only considers one pair of sides. Choice C is incorrect as it adds all sides together without considering the pairs. Choice D is incorrect as it only considers one side length.
