Math HESI A2 Practice Test

Correct Answer: B

Rationale: To convert pints to ounces, we know that 1 pint is equal to 16 ounces. Therefore, 8 1/4 pints can be calculated as 8 x 16 + 4 = 132 ounces. This is why choice B (132 oz) is correct. Choices A, C, and D are incorrect because they do not accurately represent the conversion of pints to ounces in this scenario.

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.

Correct Answer: D

Rationale: To convert quarts to ounces, we know that 1 quart equals 32 ounces. Therefore, 3 quarts would equal 3 x 32 = 96 ounces. This makes answer choice D (96 ounces) the correct option. Choice A (64 ounces) is incorrect because it miscalculates the conversion. Choice B (32 ounces) is incorrect as it represents 1 quart, not 3 quarts. Choice C (48 ounces) is also incorrect as it is an intermediate value between the correct answer and the incorrect answer A.

Correct Answer: C

Rationale: To calculate the surface area of the rectangular box, you need to find the area of each face. The box has 6 faces, and each face's area is 40*30cm=1200cm². Therefore, the total surface area is 6*1200cm²=7200cm²=0.72m². Since one sheet covers 0.5m², you need 0.72m²/0.5m²=1.2 sheets of cardboard, which is equivalent to 1.2m². This is why option C, 1.2 sq m, is the correct answer. Option A (0.3 sq m), B (0.6 sq m), and D (1.8 sq m) are incorrect as they do not align with the correct calculation of the surface area of the rectangular box.

Correct Answer: D

Rationale: To find 50% of 120, you multiply 120 by 0.50 (which represents 50%). So, 120 x 0.50 = 60. Therefore, the correct answer is D. Choice A (50) is incorrect because it represents the percentage value, not the result of the calculation. Choice B (50) is a duplicate of Choice A. Choice C (70) is incorrect as it is not the result of finding 50% of 120.
