HESI A2 Quizlet Math Questions

Question 1 of 5

If 3 books cost $4, how much will 6 books cost?

Correct Answer: A

Rationale: To find the cost of 6 books, we can use the proportion method. Since 3 books cost $4, 1 book costs $4/3. To find the cost of 6 books, we multiply the cost of 1 book by 6, which gives $8. Therefore, the correct answer is A: $8. The other choices are incorrect because they do not follow the logical calculation based on the initial cost of 3 books and the concept of proportionality.

Question 2 of 5

Sarah had 1 quart of milk. How many ounces of milk is that?

Correct Answer: C

Rationale: To convert quarts to ounces, we know that 1 quart equals 32 ounces. This is because 1 quart = 32 fluid ounces. So, when Sarah has 1 quart of milk, she has 32 ounces. Therefore, the correct answer is C: 32 ounces. A: 16 ounces - Incorrect. 1 pint is equal to 16 ounces, not 1 quart. B: 24 ounces - Incorrect. There is no direct conversion relationship between quarts and 24 ounces. D: 48 ounces - Incorrect. 1 gallon is equivalent to 128 ounces, not 1 quart.

Question 3 of 5

If a person wants to plant 65,536 trees so that the number of rows equals the number of trees in each row, how many trees should they plant in each row?

Correct Answer: D

Rationale: To find the number of trees in each row: 1. Take the square root of the total number of trees: √65,536 = 256. 2. Since the number of rows equals the number of trees in each row, the correct answer is 256 (D). Choice A, 1684, is incorrect as it is not a factor of 65,536. Choice B, 1268, and Choice C, 668, are also incorrect as they do not satisfy the condition of having an equal number of rows and trees in each row.

Question 4 of 5

A honeycomb cell has six equal sides, each measuring 8mm. What is its perimeter?

Correct Answer: C

Rationale: To find the perimeter of the honeycomb cell, we add the lengths of all six sides, which are 8mm each. Perimeter = 6 * 8mm = 48mm. Choice C (48mm) is correct. Other choices are incorrect because they do not account for the total length of all sides. Option A (32mm) would be the perimeter of a square with sides of 8mm. Option B (40mm) and Option D (56mm) are not the correct total length of all six sides.

Question 5 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.
