TEAS Math Practice Test Questions

Question 1 of 5

A scientist is trying to determine how much poison will kill a rat the fastest. Which of the following statements is an example of an appropriate hypothesis?

Correct Answer: C

Rationale: The correct answer is C because it presents a clear and testable hypothesis that directly links the amount of poison given to the speed of rat death. It follows the format of an appropriate hypothesis by stating a cause-and-effect relationship that can be tested through experimentation. A is incorrect because it lacks a specific hypothesis and does not propose a clear relationship between the amount of poison and rat death. B is incorrect as it poses a question rather than a hypothesis, and it does not establish a direct connection between the variables. D is incorrect because it is a general statement about poison and rats without proposing a specific hypothesis to test.

Question 2 of 5

What is 15% of 200?

Correct Answer: A

Rationale: To find 15% of 200, you multiply 200 by 0.15 (which is the decimal equivalent of 15%). 200 * 0.15 = 30. Therefore, the correct answer is A (30). Option B (20) is incorrect because it represents 10% of 200. Option C (25) is incorrect as it is not the result of calculating 15% of 200. Option D (40) is incorrect as it is the result of multiplying 20% by 200.

Question 3 of 5

What are all the factors of 12?

Correct Answer: D

Rationale: The factors of a number are the integers that can divide the number without leaving a remainder. To find the factors of 12, we start with 1 and check each integer up to 12. 1, 2, 3, 4, 6, and 12 are all factors of 12 because they divide evenly into 12. Choice D is correct because it lists all the factors of 12. Choices A, B, and C include numbers that are not factors of 12, making them incorrect.

Question 4 of 5

Your measurement of the width of a door is 36 inches. The actual width of the door is 35.75 inches. What is the relative error in your measurement?

Correct Answer: A

Rationale: To calculate relative error, we use the formula: (|Measured Value - Actual Value| / Actual Value) x 100%. In this case, the calculation is: (|36 - 35.75| / 35.75) x 100% = (0.25 / 35.75) x 100% ≈ 0.70%. Therefore, the correct answer is A (0.70%). Choice B (0.01%) is too small, choice C (0.99%) and choice D (0.10%) are too large compared to the calculated relative error of 0.70%.

Question 5 of 5

What is the perimeter of a rectangle with a length of 7 cm and a width of 3 cm?

Correct Answer: D

Rationale: To find the perimeter of a rectangle, we add the lengths of all four sides. For this rectangle with a length of 7 cm and width of 3 cm, the perimeter formula is P = 2(length + width). Substituting in the values, we get P = 2(7 + 3) = 2(10) = 20 cm. Therefore, the correct answer is D (20 cm). Option A (21 cm) is incorrect as it exceeds the sum of the length and width. Option B (10 cm) is incorrect as it only accounts for one side. Option C (14 cm) is incorrect as it doesn't consider all four sides.
