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: A

Rationale: To subtract mixed numbers, first convert them to improper fractions. 12 1/8 = 97/8 and 9 1/2 = 19/2. Then, subtract the fractions: 97/8 - 19/2 = 97/8 - 38/8 = 59/8. Finally, convert the result back to a mixed number: 59/8 = 7 3/8. Therefore, the correct answer is A: 2 5/8. Choices B, C, and D are incorrect because they do not match the result of the subtraction calculation.

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.

Correct Answer: A

Rationale: To solve the equation 5x + 10 = 20, first subtract 10 from both sides to isolate the variable: 5x = 10. Then, divide by 5 on both sides to solve for x: x = 2. Therefore, the correct answer is A (4) because x = 2 satisfies the original equation. Choices B, C, and D are incorrect as they do not yield a solution that satisfies the equation.

Correct Answer: A

Rationale: To divide mixed numbers, convert them to improper fractions. 4 7/8 = (8*4 + 7)/8 = 39/8 and 1 1/6 = (6*1 + 1)/6 = 7/6. Then divide 39/8 by 7/6: (39/8) ÷ (7/6) = (39/8) * (6/7) = 234/56 = 4 5/28 (Choice A). The other choices are incorrect because they do not yield the correct result when following the correct steps for dividing mixed numbers.
