HESI A2 Math Questions
Question 1 of 5
A marathon runner completes 21.4 miles and burns 2276 calories. What is her rate of calories burned per mile?
Correct Answer: B
Rationale:
To find the rate of calories burned per mile, divide the total calories burned by the total miles run. In this case, 2276 calories · 21.4 miles = 106.4 calories per mile.
Therefore, the correct answer is B.
Choice A (106.3) is incorrect because it is slightly lower than the calculated value.
Choice C (106.355) is incorrect as it is a more precise value than the calculation result.
Choice D (106.36) is also incorrect as it is a more precise value than the calculated answer.
Question 2 of 5
What is the result of adding 6 3/4 + 8 1/6?
Correct Answer: A
Rationale:
To add mixed numbers, first convert them to improper fractions. 6 3/4 = 27/4 and 8 1/6 = 49/6. Finding a common denominator, we get 27/4 + 49/6 = 81/12 + 98/12 = 179/12 = 14 & 11/12.
Therefore, the correct answer is A.
Choice B is incorrect as it does not simplify to the correct result.
Choice C is in fraction form and not in mixed number form, making it incorrect.
Choice D is not the correct sum of the given mixed numbers, so it is also incorrect.
Question 3 of 5
If Randy sells 8 times as many vacuum cleaners as Janice, and Janice sells 690 vacuum cleaners per year, on average, how many does Randy sell each month?
Correct Answer: B
Rationale: If Janice sells 690 vacuum cleaners per year, Randy sells 8 times that amount, which is 690 x 8 = 5,520 vacuum cleaners per year.
To find out how many Randy sells each month, you divide 5,520 by 12 (months), which equals 460 vacuum cleaners per month.
Therefore, Randy sells 5,520 vacuum cleaners per year divided by 12 months, which equals 460 vacuum cleaners per month.
Choices A, C, and D are incorrect as they do not reflect the correct calculation based on the information provided.
Question 4 of 5
A family uses 12 gallons of water every day. How many gallons do they use in a non-leap year?
Correct Answer: B
Rationale:
To determine the total gallons the family uses in a non-leap year, you have to multiply the daily consumption by the number of days in a non-leap year. So, 12 gallons/day x 365 days = 4,380 gallons used per year.
Therefore, the correct answer is B.
Choice A is incorrect as it provides an inaccurate total by not considering the total days in a year.
Choice C is incorrect as it offers a lower value due to not multiplying the daily usage by the total days in a year.
Choice D is incorrect as it doesn't accurately calculate the total gallons used in a non-leap year.
Question 5 of 5
If a recipe calls for 2 cups of sugar and you want to make half of the recipe, how many cups of sugar do you need?
Correct Answer: A
Rationale:
To make half of the recipe that calls for 2 cups of sugar, you would need 1 cup of sugar.
Choice A is correct because half of 2 cups is 1 cup.
Choice B (1.5 cups) is incorrect as it is three-quarters of the original amount, not half.
Choice C (2 cups) is the amount required for the full recipe, not for half.
Choice D (0.5 cups) is half of 1 cup, not half of 2 cups.
