HESI A2 Quizlet Math Questions

Question 1 of 5

If the elephant weighed 3 tons, how many pounds did it weigh?

Correct Answer: A

Rationale: To convert tons to pounds, you multiply the weight in tons by 2000 (since 1 ton = 2000 pounds). Therefore, 3 tons x 2000 = 6000 pounds. Choice A (6000 pounds) is correct. Choices B, C, and D are incorrect because they do not correctly convert 3 tons to pounds. B (5000 pounds) is too low, C (3000 pounds) is even lower, and D (7000 pounds) is too high.

Question 2 of 5

A honeycomb cell has six equal sides, each measuring 8mm. What is its perimeter?

Correct Answer: C

Rationale: To find the perimeter of the honeycomb cell, we add the lengths of all six sides, which are 8mm each. Perimeter = 6 * 8mm = 48mm. Choice C (48mm) is correct. Other choices are incorrect because they do not account for the total length of all sides. Option A (32mm) would be the perimeter of a square with sides of 8mm. Option B (40mm) and Option D (56mm) are not the correct total length of all six sides.

Question 3 of 5

81:X::9:27. Find X.

Correct Answer: B

Rationale: To find X, we can see that 81 is the square of 9 and 27 is the cube of 3. Therefore, X should be the cube root of 81, which is 3. Hence, the correct answer is B. Choice A is incorrect because 3 is the cube root of 27, not 81. Choice C is incorrect as 21 is not a perfect cube of any number. Choice D is incorrect because 9 is the cube itself, not the cube root.

Question 4 of 5

An IV drip delivers medication at a rate of 40 drops per minute. Each drop contains 0.05 milliliters of the medication. How many milliliters of medication are delivered in one hour?

Correct Answer: D

Rationale: To calculate the amount of medication delivered in one hour, first find the amount delivered in one minute: 40 drops/min * 0.05 mL/drop = 2 mL/min. Then, multiply by the number of minutes in an hour: 2 mL/min * 60 min = 120 mL. Therefore, the correct answer is D (120 milliliters). Summary: A: Incorrect. Not enough medication delivered. B: Incorrect. Not enough medication delivered. C: Incorrect. Too low of an amount delivered.

Question 5 of 5

How many meters are in 5 kilometers?

Correct Answer: B

Rationale: The correct answer is B: 5000. To convert kilometers to meters, you need to multiply by 1000 since there are 1000 meters in a kilometer. So, 5 kilometers x 1000 = 5000 meters. Choice A (1000) is the number of meters in 1 kilometer, not 5. Choice C (10000) is the result of multiplying 10 kilometers by 1000. Choice D (500) is incorrect as it is not the correct conversion from kilometers to meters.
