HESI A2 Quizlet Math

Correct Answer: A

Rationale: To determine the money left after shopping, subtract the total expenses ($101.85 + $21.90 + $42.66 = $166.41) from the initial cash amount ($200.00). Thus, $200.00 - $166.41 = $33.59 left. Choice A is correct. Choices B, C, and D are incorrect as they do not reflect the accurate remaining amount after subtracting the total expenses from the initial cash.

Correct Answer: D

Rationale: To calculate the percentage decrease, we use the formula: (Original Price - New Price) / Original Price * 100%. In this case, it would be (200 - 150) / 200 * 100% = 50 / 200 * 100% = 25%. Therefore, the correct answer is D (25%). Option A (5%), B (10%), and C (20%) are incorrect as they do not accurately represent the 25% decrease in price.

Correct Answer: A

Rationale: 125% can be written as 125/100, which simplifies to 5/4 by dividing both numerator and denominator by the greatest common divisor (25). This is the correct fraction representation of 125%. Choice B (1/8) is incorrect as it represents 12.5%. Choice C (5/2) is incorrect as it represents 250%. Choice D (25/2) is incorrect as it represents 1250%.

Correct Answer: A

Rationale: To convert milliliters to liters, you divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 5000 milliliters divided by 1000 equals 5 liters. Choice A is correct as it accurately converts 5000 milliliters into liters. Choices B, C, and D are incorrect as they do not correctly convert the given milliliters to liters.

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.
