HESI A2 Quizlet Math Questions

Question 1 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.

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

81:X::9:27. Find X.

Correct Answer: B

Rationale: To find X, we can see that 81 is the square of 9 and 27 is the cube of 3. Therefore, X should be the cube root of 81, which is 3. Hence, the correct answer is B. Choice A is incorrect because 3 is the cube root of 27, not 81. Choice C is incorrect as 21 is not a perfect cube of any number. Choice D is incorrect because 9 is the cube itself, not the cube root.

Question 4 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 5 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.
