HESI A2 Math Practice

Correct Answer: B

Rationale: To find the total number of shipping labels needed per day, we multiply the number of boxes by the number of labels per box: 9 boxes x 3 labels = 27 labels. This is why choice B (27 labels) is correct. Choice A (24 labels) results from multiplying the boxes by labels incorrectly. Choice C (20 labels) and choice D (30 labels) are both too low and too high respectively, indicating an incorrect understanding of the calculation required.

Correct Answer: A

Rationale: The correct answer is A: 1/6. There is only one face showing a 5 on a six-sided die, so the favorable outcome is 1. The total number of possible outcomes when rolling a six-sided die is 6. Therefore, the probability of rolling a 5 is 1/6. Choice B (1/4) is incorrect because there is only one face showing a 5 out of 6 possible outcomes, not 4. Choice C (1/2) is incorrect as it represents the probability of rolling an even number on a six-sided die, not specifically a 5. Choice D (1/3) is incorrect as it does not accurately represent the probability of rolling a 5 on a six-sided die.

Correct Answer: B

Rationale: To convert grams to kilograms, we need to divide by 1000 since there are 1000 grams in 1 kilogram. Therefore, 2000 grams divided by 1000 equals 2 kilograms. Choice B is correct. Choices A, C, and D are incorrect as they do not accurately convert 2000 grams to kilograms. A (20 kg) is 10 times the correct answer, C (5 kg) is incorrect as it is half the correct answer, and D (10 kg) is also incorrect as it is 5 times the correct answer.

Correct Answer: A

Rationale: To express 0.025 as a ratio, we need to convert it to a fraction first. 0.025 as a fraction is 25/1000. Simplifying this gives us 1/40. Therefore, the correct ratio is 1:40. Choice A is correct as it represents the simplified form of 0.025 as a ratio. Choices B, C, and D are incorrect as they do not represent the equivalent simplified ratio of 0.025.

Correct Answer: B

Rationale: To solve for x in the equation 3x + 9 = 0, first, subtract 9 from both sides to isolate 3x. This gives you 3x = -9. Next, divide both sides by 3 to solve for x, which results in x = -3. Therefore, the correct answer is B. Choice A is incorrect as it does not account for the correct arithmetic operations. Choice C is incorrect because it does not yield a solution that satisfies the equation. Choice D is incorrect as it does not follow the correct steps to solve for x.
