Math HESI A2 Practice Test Questions
Question 1 of 5
A farmer has 240 acres under cultivation at the cost of $188.99 per acre. If he averages a yield of 60 bushels per acre, what profit is expected if the price per bushel is $5.67?
Correct Answer: A
Rationale: To calculate the profit, we first find the total cost of cultivation: 240 acres * $188.99/acre = $45,357.60. Then, we find the total revenue from selling the yield: 240 acres * 60 bushels/acre * $5.67/bushel = $81,648. Finally, we subtract the cost from the revenue to get the profit: $81,648 - $45,357.60 = $36,290.40. Therefore, the correct answer is A. Choice B is incorrect because it miscalculates the profit by not subtracting the cost from the revenue. Choice C is incorrect as it overestimates the profit. Choice D is incorrect as it is not the accurate profit value based on the given information.
Question 2 of 5
Solve for x: 2x - 7 = 9.
Correct Answer: C
Rationale: To solve for x, add 7 to both sides of the equation: 2x - 7 + 7 = 9 + 7. This simplifies to 2x = 16. Then, divide by 2 on both sides to get x = 8. This is the correct answer (C) because it correctly follows the principles of algebra. Choices A, B, and D are incorrect as they do not yield the correct solution when substituted back into the original equation.
Question 3 of 5
A syringe holds 3ml of liquid. How many syringes are needed to measure 15ml of liquid?
Correct Answer: B
Rationale: To measure 15ml of liquid using a syringe that holds 3ml, you would need to divide 15ml by 3ml to determine the number of syringes needed. 15ml ÷ 3ml = 5 syringes. Therefore, the correct answer is B: 5 syringes. Choice A (3 syringes) is too few, choice C (7 syringes) and choice D (9 syringes) are too many based on the calculation.
Question 4 of 5
Which number system is commonly used in the United States?
Correct Answer: B
Rationale: The correct answer is B: Decimal. The decimal number system is commonly used in the United States because it is based on powers of 10, making it easy for people to understand and use in everyday life, such as in currency, measurements, and calculations. Tertiary and Napoleonic number systems are not commonly used in the United States. Binary is a base-2 number system, which is used in computer science but not as widely used in everyday life in the US.
Question 5 of 5
How many liters are in 2500 milliliters?
Correct Answer: A
Rationale: To convert milliliters to liters, we divide by 1000 since 1 liter = 1000 milliliters. So, 2500 milliliters ÷ 1000 = 2.5 liters. Therefore, the correct answer is A: 2.5 liters. Explanation for other choices: B: 1.5 liters - Incorrect, obtained by incorrect division. C: 3.5 liters - Incorrect, obtained by adding instead of dividing. D: 0.25 liters - Incorrect, obtained by misplaced decimal point.
