HESI A2 Math Questions
Question 1 of 5
A farmer buys 3 bags of feed weighing 50 kilograms each. How much feed does he have in total?
Correct Answer: B
Rationale: To find the total feed weight, we multiply the weight of one bag by the number of bags. 50 kg x 3 bags = 150 kg. Therefore, the correct answer is B (150 kilograms). Option A (100 kg) is incorrect as it represents the weight of 2 bags only. Option C (200 kg) and Option D (250 kg) are incorrect as they miscalculate the total weight by either adding or multiplying the weights incorrectly.
Question 2 of 5
If Andy runs five times as long as Jake, and Jake runs 24.5 miles each week, how many miles does Andy run in a day?
Correct Answer: A
Rationale: To find Andy's daily mileage, we first calculate Jake's daily mileage: 24.5 miles / 7 days = 3.5 miles/day. Since Andy runs five times as much, he runs 3.5 * 5 = 17.5 miles/day. Therefore, the correct answer is A. Choice B (17.7) is incorrect because it is not the result of the calculation in this scenario. Choice C (16.5) is incorrect as it does not account for Andy running five times as much as Jake. Choice D (18.2) is incorrect because it does not align with the correct calculation based on the information provided.
Question 3 of 5
If Larry can wash 50 cars in 20 minutes, how many minutes will it take him to wash 80 cars?
Correct Answer: B
Rationale: To find the time to wash 80 cars, we use the formula: Time = (Number of cars * Time taken for 1 car)/(Number of cars washed in that time). Time = (80 * 20)/(50) = 32 minutes. Choice B is correct. Choice A is incorrect as it assumes the time taken is constant. Choice C and D are incorrect as they do not consider the increase in the number of cars to be washed.
Question 4 of 5
In a bar graph showing the number of patients admitted to the ER each day for a week, how do you determine the day with the highest number of admissions?
Correct Answer: A
Rationale: To determine the day with the highest number of admissions in a bar graph, you need to find the tallest bar. The height of each bar represents the number of admissions for a specific day. By identifying the tallest bar, you can easily pinpoint the day with the highest number of admissions. Comparing bar heights (choice B) may be time-consuming and unnecessary. Calculating the average number of admissions per day (choice C) provides an overall view but doesn't directly identify the day with the highest admissions. Subtracting the lowest from the highest number of admissions (choice D) is not needed as the focus is on identifying the highest day, not the range.
Question 5 of 5
A nurse works in a neonatal unit where infants' weights are measured in grams. What is the equivalent of 1,500 grams in pounds?
Correct Answer: A
Rationale: To convert grams to pounds, divide the weight in grams by 453.592 (1 pound is approximately equal to 453.592 grams). Therefore, to convert 1,500 grams to pounds, you would do 1500 / 453.592 = 3.30693393, which rounds down to 3.3 pounds (Answer A). The other choices are incorrect as they do not provide the accurate conversion from grams to pounds. Answer A is the correct choice as it is the result of the precise calculation.
