Practice Math TEAS TEST

Correct Answer: B

Rationale: To find 31% of 426, you multiply 426 by 0.31. So, 426 * 0.31 = 132.06. Therefore, the correct answer is B: 132.06. Option A (425.69) is close but incorrect. Options C (13.7) and D (0.07) are significantly lower than the actual result, indicating they are incorrect.

Correct Answer: B

Rationale: The independent variable is the one that is manipulated or changed by the researcher in an experiment. In this scenario, the number of credit hours a student takes is the variable that is being controlled or changed to observe its effect on other variables such as tuition, access fees, and student loans. The amount of credit hours is not dependent on any other variable in this context, making it the independent variable. In contrast, the amount of tuition, access fees, and student loans are dependent on the number of credit hours taken by the student, making them dependent variables. Therefore, the correct answer is B: Number of credit hours. Choices A, C, and D are incorrect as they are all dependent variables that are influenced by the number of credit hours taken by the student.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Friend 1 eats half, leaving half for the other 3 friends. 2. The remaining half is divided equally among the 3 friends. 3. So, each friend gets 1/3 of the remaining half. 4. 1/3 represents the portion each of the other 3 friends receives, making choice A the correct answer. Summary: - Incorrect choices B, C, and D are not correct as they do not accurately represent the portion each of the other three friends would receive after one friend eats half of the pizza.

Correct Answer: A

Rationale: The correct answer is A: 1000 mL. This is because there are 1000 milliliters in a liter based on the metric system conversion. 1 liter is equal to 1000 milliliters. Therefore, to convert liters to milliliters, you simply multiply the number of liters by 1000. Choice B: 100 mL is incorrect because it is not the standard conversion factor for liters to milliliters. Choice C: 10 mL is incorrect as it is too small of a quantity to be equivalent to a liter. Choice D: 1 mL is incorrect as it is significantly less than a liter.

Correct Answer: A

Rationale: The correct answer is A: 9.0 inches. To calculate the total rainfall for May, June, and July, we add up the rainfall values for these months on the graph. May has 3 inches, June has 2.5 inches, and July has 3.5 inches. Adding these values together gives us 3 + 2.5 + 3.5 = 9.0 inches. Therefore, the correct total rainfall for these months is 9.0 inches. Choice B (8.4 inches) is incorrect because it does not match the sum of the rainfall values for May, June, and July. Choice C (7.5 inches) is also incorrect as it is lower than the actual total. Choice D (10.5 inches) is incorrect as it is higher than the actual total calculated from the graph.
