Math Practice TEAS Test

Correct Answer: A

Rationale: The correct answer is A: Inches are larger. This is because one inch is equivalent to 2.54 centimeters. Therefore, when comparing the two units, inches are larger in size. Centimeters are smaller units of measurement compared to inches. Choice B is incorrect as centimeters are smaller. Choice C is incorrect because they are not the same size. Choice D is incorrect as the relationship between inches and centimeters is fixed with 1 inch being larger than 1 centimeter.

Correct Answer: A

Rationale: The correct answer is A: Ranges. Histograms display continuous data in intervals or ranges, showing the frequency of data points within each range. This is a key feature that distinguishes histograms from bar graphs, which depict discrete categories. Ranges are crucial in histograms to visualize the distribution of data across different intervals, allowing for a better understanding of the data's spread and frequency distribution. Choices B, C, and D are incorrect as bar graphs also utilize categories, labels, and percentages in their presentation of data, respectively.

Correct Answer: B

Rationale: To simplify the expression, we follow the order of operations (PEMDAS/BODMAS). First, we calculate the multiplication and division from left to right: 6 + 7 = 13, 13 - 4 = 9, 9 * 2 = 18. So, the correct answer is 18. Choice A is incorrect because it is the result of multiplying all the numbers together. Choice C is incorrect as it is the result of adding all the numbers together. Choice D is incorrect as it is the result of adding the first two numbers and then multiplying by the last two numbers.

Correct Answer: A

Rationale: The correct answer is A: Inches are larger. This is because one inch is equivalent to 2.54 centimeters. Therefore, when comparing the two units, inches are larger in size. Centimeters are smaller units of measurement compared to inches. Choice B is incorrect as centimeters are smaller. Choice C is incorrect because they are not the same size. Choice D is incorrect as the relationship between inches and centimeters is fixed with 1 inch being larger than 1 centimeter.

Correct Answer: B

Rationale: To find the total height when stacked, we add the heights of the two bookcases. 32.75 inches + 17.25 inches = 50 inches Therefore, the correct answer is B (50 inches). Explanation for incorrect choices: A: 49.5 inches is incorrect because the heights are added, not averaged. C: 48 inches is incorrect as it's less than the sum of the two heights. D: 51 inches is incorrect as it's greater than the sum of the two heights.
