HESI A2 Math Practice Questions

Question 1 of 5

What is the temperature in Celsius when it is 98.6 degrees Fahrenheit?

Correct Answer: B

Rationale:
To convert 98.6 degrees Fahrenheit to Celsius, you can use the formula (98.6 - 32) 5/9. By solving this equation, the temperature is calculated to be 37°C.
Therefore, the correct answer is B, 37 Celsius.
Choice A, 35 Celsius, is incorrect because it is not the outcome of the conversion formula.
Choice C, 38 Celsius, is incorrect as well, as it does not match the correct conversion result.
Choice D, 36.5 Celsius, is also incorrect as it does not correspond to the accurate conversion from 98.6 degrees Fahrenheit.

Question 2 of 5

A woman received a bottle of perfume as a present. The bottle contains 3/4 oz of perfume. How many milliliters is this?

Correct Answer: B

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Question 3 of 5

How many kilograms are in 2000 grams?

Correct Answer: B

Rationale:
To convert grams to kilograms, you need to divide by 1000 since there are 1000 grams in a kilogram.
Therefore, 2000 grams is equal to 2 kilograms (2000 grams · 1000 = 2 kilograms). The correct answer is B: 2 kilograms.
Choice A, 20 kilograms, is incorrect because multiplying by 10 (not dividing by 1000) would give that result.
Choice C, 5 kilograms, and
Choice D, 10 kilograms, are also incorrect as they do not correctly convert grams to kilograms.

Question 4 of 5

A worker in a warehouse ships 9 boxes each day. If every box must contain 3 shipping labels, how many shipping labels does the worker need each day?

Correct Answer: B

Rationale:
To find the total number of shipping labels needed, multiply the number of boxes by the labels per box: 9 boxes * 3 labels per box = 27 labels.
Therefore, the worker needs 27 shipping labels each day.
Choice A, 24 labels, is incorrect because it results from multiplying 9 boxes by 3 labels without calculating the correct total.
Choice C, 20 labels, is incorrect as it underestimates the total number of labels needed.
Choice D, 30 labels, is incorrect as it overestimates the total by multiplying incorrectly.

Question 5 of 5

Solve for x: x + 44 / 2x = 11.

Correct Answer: A

Rationale:
To solve the equation x + 44 / 2x = 11, first, divide 44 by 2x to simplify it to x + 22/x = 11. Multiply through by x to clear the fraction, resulting in x^2 + 22 = 11x. Rearrange the terms to get x^2 - 11x + 22 = 0. Factor the quadratic equation to (x - 11)(x - 2) = 0.
Therefore, x = 11 or x = 2. However, x cannot be 2 as it would make the denominator zero. Hence, x = 13. The correct answer is 13.
Choice B (33) is incorrect as it is not a solution to the equation.
Choice C (55) is incorrect as it is not a solution to the equation.
Choice D (2.5) is incorrect as it is not a whole number and does not satisfy the equation.
