HESI A2 Practice Test Math

Correct Answer: A

Rationale: To calculate the nurse's earnings for the week, we first find her total hours worked: 2(12 hours) + 2(8 hours) = 40 hours. Then, multiply her hourly rate of $22 by the total hours worked: $22/hour x 40 hours = $880. Therefore, the nurse earned $880 for the week. The correct answer is A ($960) because it is the only amount greater than $880, which is the actual amount earned. Choices B, C, and D are incorrect as they are higher or lower than the calculated amount of $880.

Correct Answer: C

Rationale: To find x, we can use the property of proportionality. The given equation can be rewritten as 120/x = 40/0.5. Simplifying, we get 120/x = 80. Cross multiplying gives 120 = 80x. Dividing both sides by 80, we find x = 120/80 = 1. Therefore, the correct answer is C. Choice A (60) is incorrect because the calculation does not yield the correct value of x. Choice B (0) is incorrect as dividing by 0 is undefined. Choice D (25) is incorrect as it does not match the calculation for x in the given equation.

Correct Answer: D

Rationale: To determine if a number is divisible by another, it must leave no remainder when divided. 7 is a prime number and can only be divided by 1 and itself (7). So, choices A and B are incorrect. Since 7 is a prime number, it is only divisible by numbers that are factors of 7 (1, 7) or itself. Therefore, choice C is also incorrect. The correct answer is D because 7 can be evenly divided by 2, 3, and 7 without any remainder, making it divisible by these numbers.

Correct Answer: A

Rationale: To calculate the total grams of carbohydrates in the product, you multiply the number of servings by the grams of carbohydrates per serving. In this case, 4 servings x 8 grams/serving = 32 grams of carbohydrates. Therefore, the correct answer is A. Explanation for other choices: B: 4 servings x 8 grams/serving does not equal 28 grams. C: 4 servings x 8 grams/serving does not equal 24 grams. D: 4 servings x 8 grams/serving does not equal 20 grams.

Correct Answer: A

Rationale: To find the number of floors, divide the total height of the building (150 feet) by the height of each floor (12 feet). 150 ÷ 12 = 12.5. Since we cannot have a fraction of a floor, we must round down to the nearest whole number, which is 13. Therefore, the correct answer is A: 13 floors. The other choices are incorrect because they do not accurately represent the result of dividing the total height by the height of each floor.
