HESI A2 Quizlet Math

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.

Correct Answer: A

Rationale: To find the total cost of the comics, multiply $2.65 by 3, which equals $7.95. To determine the change, subtract the total cost from the amount paid: $20 - $7.95 = $12.05. Therefore, Robert received $12.05 in change. Option B is incorrect because it miscalculates the change. Option C is incorrect as it only accounts for one comic's cost. Option D is incorrect as it does not consider the total cost of all three comics.

Correct Answer: A

Rationale: The correct answer is A: 32,000 ounces in a ton. There are 16 ounces in a pound, and 2,000 pounds in a ton. Therefore, to find the number of ounces in a ton, you multiply 16 (ounces per pound) by 2,000 (pounds in a ton), resulting in 32,000 ounces. Choice B (30,000 ounces) is incorrect because it does not account for the correct conversion factor between pounds and ounces in a ton. Choice C (35,000 ounces) and Choice D (40,000 ounces) are also incorrect as they similarly do not follow the correct conversion logic.

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.

Correct Answer: A

Rationale: To find the product of 44.44 and 55.55, you multiply the two numbers: 44.44 * 55.55 = 2,468.64 Therefore, the correct answer is A. Choice B is incorrect as it is a round number and not the precise result of the multiplication. Choice C is incorrect because it does not match the result of the calculation. Choice D is also incorrect as it is not the exact product of the given numbers.
