HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: To solve for x, substitute x=11 into the expression x+(44/2x): 11 + (44/(2*11)) 11 + (44/22) 11 + 2 = 13 Therefore, the correct answer is D. Choice A: 2.5 is incorrect as the calculation results in 13, not 2.5. Choice B: 33 and C: 55 are also incorrect as they do not align with the correct calculation of 13.

Correct Answer: A

Rationale: To solve 7 1/8 + 2 4/12, first convert 2 4/12 to an improper fraction: 2 4/12 = 2 + 1/3 = 2 1/3 = 7/3. Now, add 7 1/8 and 7/3 by finding a common denominator, which is 24. 7 1/8 = 57/8. Add 57/8 and 7/3 to get 183/24. Simplify 183/24 to 9 11/24, which is the correct answer (A). Choices B, C, D are incorrect as they do not match the calculated result.

Correct Answer: B

Rationale: To find the length of the room, we use the formula for the area of a rectangle: Area = Length x Width. Given that the area is 225 sq ft and the width is 15 ft, we can substitute these values into the formula: 225 = Length x 15. Solving for Length, we get Length = 225 / 15 = 15 feet. Therefore, the correct answer is B: 15 feet. Choice A (30 feet) is incorrect because it is twice the width and does not align with the given area. Choice C (25 feet) is incorrect because it does not satisfy the area requirement. Choice D (45 feet) is incorrect as it is not consistent with the given width and area.

Correct Answer: C

Rationale: The tenths place is the first digit to the right of the decimal point. In the number 743.25, the digit 2 is in the tenths place because it is the first digit to the right of the decimal point. Therefore, the correct answer is C. Explanation for why the other choices are incorrect: - A: 3 is in the units place, not the tenths place. - B: 4 is in the tenths place, not the tenths place. - D: 5 is in the hundredths place, not the tenths place.

Correct Answer: A

Rationale: To calculate the number of cakes needed, divide the total number of servings needed (70 students + 3 staff) by the number of servings per cake. Total servings needed = 70 + 3 = 73. 73 servings ÷ 24 servings per cake = 3 with a remainder of 1. Since we can't have a fraction of a cake, we need to round up to the nearest whole number. So, we need 4 cakes to ensure there are enough servings for everyone. Therefore, the correct answer is A: 4. Choice B (2) is incorrect because it doesn't provide enough servings for all students and staff members. Choice C (5) is incorrect as it would be an excessive amount of cakes. Choice D (3) is incorrect as it doesn't account for the remaining servings after dividing by 24.
