HESI A2 Quizlet Math Questions

Question 1 of 5

How many grams are in 4 kilograms?

Correct Answer: A

Rationale: To convert kilograms to grams, you need to multiply the number of kilograms by 1000, as there are 1000 grams in 1 kilogram. Therefore, 4 kilograms x 1000 = 4000 grams, which is the correct answer (A). Choices B, C, and D are incorrect because they do not correctly convert 4 kilograms to grams.

Question 2 of 5

When a die is rolled, what is the probability of rolling an odd number?

Correct Answer: D

Rationale: The correct answer is D (50%). A die has 6 sides with numbers 1 to 6. There are 3 odd numbers (1, 3, 5) out of the total 6 numbers. Therefore, the probability of rolling an odd number is 3/6, which simplifies to 1/2 or 50%. Choice A (16.67%) is incorrect because it represents the probability of rolling a specific odd number (1 out of 6 options) rather than any odd number. Choice B (33.33%) is incorrect as it assumes the die has only 3 sides, each representing an odd number. Choice C (75%) is incorrect as it represents the probability of rolling an odd number as if there are only odd numbers on the die.

Question 3 of 5

A rancher has a herd of different-colored horses in his corral. Ten of the horses are black, six are brown, eight are two-color horses, and three are all white. What percentage of the horses are brown? (Round to the nearest whole number if necessary).

Correct Answer: B

Rationale: To find the percentage of brown horses, we need to calculate the total number of horses first. Total = 10 (black) + 6 (brown) + 8 (two-color) + 3 (white) = 27 horses. Next, calculate the percentage of brown horses: (6 brown horses / 27 total horses) x 100% = 22.22%. Since we need to round to the nearest whole number, the percentage of brown horses is 22%, which is closest to choice B (20%). Therefore, the correct answer is B. Explanation for other choices: A: 15% - Incorrect because the percentage of brown horses is closer to 22%. C: 25% - Incorrect because the percentage of brown horses is not as high as 25%. D: 30% - Incorrect because the percentage of brown horses is lower than 30%.

Question 4 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.

Question 5 of 5

How many feet are in 3 yards?

Correct Answer: B

Rationale: To convert yards to feet, we know that 1 yard is equal to 3 feet. Therefore, to find out how many feet are in 3 yards, we multiply 3 (yards) by 3 (feet per yard), which equals 9 feet. So, the correct answer is B: 9 feet. A: 18 feet - Incorrect, as it doubles the correct answer. C: 12 feet - Incorrect, as it is derived from multiplying 3 yards by 4 feet instead of 3 feet. D: 27 feet - Incorrect, as it multiplies 3 yards by 9 feet, which is incorrect conversion.
