HESI A2 Math Practice Exam Questions
Question 1 of 5
Convert 45 kg to pounds.
Correct Answer: D
Rationale:
To convert kilograms to pounds, you multiply the weight in kilograms by 2.20462.
Therefore, to convert 45 kg to pounds, you would perform the calculation: 45 kg * 2.20462 = 99.2079 pounds. Rounding to the nearest whole number, the answer is approximately 110 pounds.
Choice A (10 pounds) is incorrect as it is too low.
Choice B (100 pounds) and
Choice C (1,000 pounds) are also incorrect as they are too high. The correct conversion is closest to
Choice D (110 pounds).
Question 2 of 5
A worker's schedule is written in military time, and shows their shift is from 1500 to 0100. When will they get off work?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
In the time required to serve 43 customers, a server breaks 2 glasses and slips 5 times. The next day, the same server breaks 10 glasses. How many customers did she serve?
Correct Answer: C
Rationale: In the first scenario, for 43 customers served, the server broke 2 glasses and slipped 5 times. This means for each customer served, the server broke 2/43 glasses and slipped 5/43 times. The information about breaking 10 glasses the next day is irrelevant to the number of customers served.
Therefore, to find out the total number of customers served, we calculate 43 customers * (2 glasses/customer + 5 slips/customer) = 86.
Choice A, 25, is incorrect as it does not consider the total number of glasses broken or slips.
Choice B, 43, is incorrect because it only considers the initial number of customers.
Choice D, 215, is incorrect as it miscalculates the relationship between customers, glasses broken, and slips.
Question 4 of 5
Evaluate the following expression: -x + y + xy, when x = 4 and y = 2.
Correct Answer: B
Rationale:
To evaluate the expression, substitute x = 4 and y = 2 into the expression: -4 + 2 + 4*2. Calculate each term: -4 + 2 = -2, then 4*2 = 8. Adding these results gives -2 + 8 = 6.
Therefore, the correct answer is 6.
Choice A (2) is incorrect as it does not consider all terms in the expression.
Choice C (12) is incorrect as it miscalculates the result by failing to account for the negative sign.
Choice D (8) is incorrect as it doesn't consider the negative value of the first term in the expression.
Question 5 of 5
What is the result of adding 9.43 and 11.3?
Correct Answer: A
Rationale: The correct answer is A: 20.73.
To calculate the sum of 9.43 and 11.3, you simply add the two numbers together.
Therefore, 9.43 + 11.3 equals 20.73.
Choice B (21.3) is incorrect because it represents the sum of rounding the numbers up.
Choice C (22) and choice D (19.5) are also incorrect as they do not accurately reflect the sum of the provided numbers.
