Practice Math TEAS TEST

Correct Answer: B

Rationale: The correct answer is B: 1 meter. This is the best estimate for the average width of a doorway because standard doorways typically range from 0.8 to 0.9 meters wide, and rounding up to 1 meter provides a reasonable estimate. Choice A (0.5 meters) is too small for a standard doorway. Choice C (10 meters) is too large and unrealistic for a doorway. Choice D (3 meters) is wider than the typical doorway width, making it an inaccurate estimate. Therefore, B is the most appropriate estimate based on common door sizes.

Correct Answer: A

Rationale: The correct answer is A because to find the least common multiple (LCM) of two numbers, you need to list all the multiples of each number and then identify the smallest common multiple. This method ensures that you consider all possible common multiples and select the smallest one. Explanation for other choices: B: Listing factors and finding the largest common factor would result in the greatest common divisor, not the least common multiple. C: Dividing the largest number by the smallest does not give the LCM; it may give a different value altogether. D: Multiplying the two numbers together gives the product of the numbers, not the LCM.

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: D

Rationale: To find the cost of 1 syringe, divide $660 by 55 (55 syringes in a box) = $12 per syringe. To find the cost of 4 syringes, multiply $12 by 4 = $48. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not correctly calculate the cost based on the given information.
