HESI A2 Math Questions
Question 1 of 5
A farmer buys 3 bags of feed weighing 50 kilograms each. How much feed does he have in total?
Correct Answer: B
Rationale: To find the total feed weight, we multiply the weight of one bag by the number of bags. 50 kg x 3 bags = 150 kg. Therefore, the correct answer is B (150 kilograms). Option A (100 kg) is incorrect as it represents the weight of 2 bags only. Option C (200 kg) and Option D (250 kg) are incorrect as they miscalculate the total weight by either adding or multiplying the weights incorrectly.
Question 2 of 5
What is the area of a rectangular room with a length of 12 meters and a width of 10 meters?
Correct Answer: A
Rationale: To find the area of a rectangle, you multiply its length by its width. In this case, the length is 12 meters and the width is 10 meters. So, Area = Length x Width = 12m x 10m = 120 square meters. Choice A is correct as it correctly calculates the area. Choices B, C, and D are incorrect as they do not correctly calculate the area based on the given dimensions.
Question 3 of 5
What is the greatest common factor (GCF) of 12 and 18?
Correct Answer: C
Rationale: To find the GCF of 12 and 18, list the factors of each: 12: 1, 2, 3, 4, 6, 12; 18: 1, 2, 3, 6, 9, 18. The common factors are 1, 2, 3, and 6. The greatest common factor is the largest number that both 12 and 18 can be divided by without remainder, which is 6. Choice A (2) and B (3) are factors, but not the greatest common factor. Choice D (9) is a factor of 18 but not 12, so it cannot be the GCF.
Question 4 of 5
If Larry can wash 50 cars in 20 minutes, how many minutes will it take him to wash 80 cars?
Correct Answer: B
Rationale: To find the time to wash 80 cars, we use the formula: Time = (Number of cars * Time taken for 1 car)/(Number of cars washed in that time). Time = (80 * 20)/(50) = 32 minutes. Choice B is correct. Choice A is incorrect as it assumes the time taken is constant. Choice C and D are incorrect as they do not consider the increase in the number of cars to be washed.
Question 5 of 5
What is the perimeter of a square with a side length of 5 meters?
Correct Answer: B
Rationale: To find the perimeter of a square, you add up all the sides. Since a square has four equal sides, the perimeter is the side length multiplied by 4. In this case, the side length is 5 meters, so the perimeter would be 5 * 4 = 20 meters. Therefore, choice B (20 meters) is correct. Choice A (15 meters) is incorrect because it is the result of adding the side length once instead of multiplying by 4. Choice C (25 meters) and choice D (30 meters) are incorrect as they are the results of adding or multiplying incorrectly.
