Math HESI A2 Practice Test - Nurselytic

Correct Answer: A

Rationale: The correct subtraction is 12.02 - 9.99 = 2.03.
Therefore, the correct answer is A.
Choice B, 2.21, is incorrect as it does not result from the given subtraction.
Choice C, 3.17, is also incorrect.
Choice D, 7.97, is incorrect as well. Thus, A is the only correct answer.

Correct Answer: A

Rationale:
To calculate the rate of calories burned per mile, divide the total calories burned by the total miles run: 2276 · 21.4 ≈ 106.4 calories per mile. The correct answer is A.
Choice B, C, and D are incorrect as they do not match the correct calculation result.
Therefore, they can be eliminated. It is essential to divide the total calories burned by the total miles run to determine the rate of calories burned per mile accurately.

Correct Answer: D

Rationale:
To calculate 75% of 80, you multiply 0.75 by 80, which equals 60.
Therefore, the correct answer is 60.

Choices A, B, and C are incorrect because they do not represent 75% of 80.
Choice A (35) is close to 50% of 80,
Choice B (45) is close to 56.25% of 80, and
Choice C (70) exceeds 80.

Correct Answer: A

Rationale:
To produce 24 eggs in 24 hours, 4 times the number of chickens needed to produce 6 eggs is required. Since it takes 2 chickens to produce 6 eggs, 8 chickens are needed to produce 24 eggs in the same time frame.
Choice B, 12 chickens, is incorrect because it doesn't consider the proportionality between chickens and eggs.
Choice C, 18 chickens, is incorrect as it overestimates the number of chickens needed.
Choice D, 6 chickens, is incorrect as it doesn't account for the increased number of eggs required.

Correct Answer: B

Rationale: Since each syringe holds 3ml of liquid, to measure 15ml of liquid, you would need to divide 15ml by 3ml/syringe. This calculation gives you 5 syringes needed to measure 15ml of liquid.
Choice A (3 syringes) is incorrect because 3 syringes would only hold 9ml of liquid, not 15ml.
Choice C (7 syringes) and
Choice D (9 syringes) are incorrect as they would result in an excess amount of liquid, which is not needed.
