HESI A2 Quizlet Math Questions
Question 1 of 5
What percentage of her income is left after Mary spent 15%?
Correct Answer: B
Rationale: To find the percentage of income left after spending 15%, you subtract 15% from 100% (total income percentage). So, 100% - 15% = 85% left. Therefore, choice B (85%) is correct. Choices A, C, and D are incorrect as they do not accurately represent the remaining percentage of income after spending.
Question 2 of 5
What is the result of multiplying 226 by 55.3?
Correct Answer: B
Rationale: To find the product of 226 and 55.3, multiply the two numbers together: 226 * 55.3 = 12,541.8 The correct answer is B (12,541.8) because this is the accurate result of the multiplication. Choice A (12,500) is incorrect as it is a rounded-down approximation. Choice C (12,600) is incorrect as it is a rounded-up approximation. Choice D (12,450) is incorrect as it is a result of rounding down the actual product.
Question 3 of 5
Convert 5 3/4 to a decimal. Round to the nearest tenth.
Correct Answer: C
Rationale: To convert 5 3/4 to a decimal, we first convert the mixed number to an improper fraction: 5 3/4 = (4*5 + 3)/4 = 23/4. Then, divide the numerator by the denominator to get the decimal: 23 ÷ 4 = 5.75. When rounded to the nearest tenth, 5.75 becomes 5.8. Therefore, the correct answer is C (5.8). Choices A (5.75) and B (5.7) are incorrect as they do not account for rounding to the nearest tenth. Choice D (6) is incorrect as it is the closest whole number approximation, but does not accurately represent 5 3/4 as a decimal rounded to the nearest tenth.
Question 4 of 5
In a survey, 120 people were asked if they could swim. If 85% said they could, how many people could swim?
Correct Answer: B
Rationale: To find the number of people who can swim, multiply the total number of people surveyed by the percentage that can swim. In this case, 120 x 0.85 = 102. Choice B is correct. Choice A is too low as it doesn't account for the 85%. Choice C is too high. Choice D is also too low.
Question 5 of 5
Joe makes $20 an hour and Tim makes $30 an hour. How many more hours than Tim must Joe work to earn the same amount that Tim makes in 4 hours?
Correct Answer: B
Rationale: To earn the same amount as Tim in 4 hours, Joe needs to work 4 hours and earn $30/hr x 4 hrs = $120. Joe earns $20/hr, so $120 ÷ $20/hr = 6 hours for Joe to earn the same as Tim. To find how many more hours Joe must work than Tim, we subtract the hours Tim works from Joe's hours: 6 hrs - 4 hrs = 2 hours. Therefore, the correct answer is B: 2 hours. Choices A, C, and D are incorrect because they do not accurately calculate the additional hours Joe needs to work compared to Tim to earn the same amount in 4 hours.
