HESI A2 Math Questions

Question 1 of 5

A school has 500 students, and 60% of them are girls. How many girls are there in the school?

Correct Answer: B

Rationale: To find the number of girls in the school, we first calculate 60% of 500 students: 60/100 * 500 = 0.6 * 500 = 300 girls. Therefore, the correct answer is B: 300 girls. Choice A (250 girls) is incorrect as it represents 50%, not 60%. Choices C (200 girls) and D (350 girls) are also incorrect as they do not reflect the correct calculation of 60% of the total students.

Question 2 of 5

A marathon runner completes 21.6 miles and burns 2,274 calories. What is the rate of calories burned per mile?

Correct Answer: A

Rationale: To find the rate of calories burned per mile, divide the total calories burned by the total distance covered. In this case, 2,274 calories ÷ 21.6 miles = 105.28 calories per mile (rounded to two decimal places), which matches option A. This calculation is based on the fundamental concept of division, where the total calories are distributed evenly over the total distance. Choices B, C, and D are incorrect as they do not match the calculated rate. This question tests basic division skills and understanding of calculating rates.

Question 3 of 5

In a bowling team consisting of 34 members, with 18 being male, if 4 females leave the team, what percent of the remaining members are male?

Correct Answer: B

Rationale: To find the percentage of remaining members who are male after 4 females leave, we first calculate the remaining total members: 34 - 4 = 30. Since 18 members are male, the percentage of males in the remaining team is (18 / 30) * 100% = 60%. Choice B is correct. Choice A (50%) is incorrect because there are more than 50% males in the remaining team. Choice C (70%) is incorrect as it overestimates the percentage of males after 4 females leave. Choice D (55%) is incorrect because the correct percentage is 60%, not 55%.

Question 4 of 5

An artist sells paintings at $5.50 each. She has 7 stands and pays $35 per stand. What is her profit if she sells an average of 11 paintings per stand?

Correct Answer: B

Rationale: To calculate the profit: 1. Cost per stand = $35 2. Total cost for 7 stands = $35 * 7 = $245 3. Revenue from selling 11 paintings per stand = $5.50 * 11 = $60.50 per stand 4. Total revenue for 7 stands = $60.50 * 7 = $423.50 5. Profit = Total revenue - Total cost = $423.50 - $245 = $178.50 Summary: A: $245 - Incorrect. This is the total cost of the stands, not the profit. B: $178.50 - Correct. Calculated as total revenue minus total cost. C: $175 - Incorrect. Not considering the revenue generated from selling paintings. D: $423.50 - Incorrect. This is the total revenue, not the profit.

Question 5 of 5

A nurse administers 150mg of medication every 4 hours. How many milligrams will the patient receive in 24 hours?

Correct Answer: D

Rationale: To calculate the total medication received in 24 hours, we first find out how many doses will be given in 24 hours. Since a dose of 150mg is given every 4 hours, there will be 6 doses in 24 hours (24 hours / 4 hours per dose = 6 doses). Multiplying 150mg by 6 doses gives us 900mg, which is the correct answer (D). Choices A, B, and C are incorrect because they do not take into account the frequency of doses within the 24-hour period.
