TEAS 7 Math Practice Test

Correct Answer: C

Rationale: Rationale: To find a reasonable estimate, divide the total distance by the number of days. 1480 miles / 5 days = 296 miles/day. The closest option is 300 miles/day (Choice C). This is the correct answer as it is the most accurate estimate of the daily distance. Choices A, B, and D are incorrect as they are either too low or too high compared to the calculated estimate, making them unreasonable choices.

Correct Answer: C

Rationale: The correct answer is C because it asks for the greatest percentage of a specific group among the staff at Hospital X and Hospital Y. This is a broader group compared to the other choices, making it more likely to have a higher percentage. Choices A, B, and D are specific to Hospital X or Y only, limiting the pool of individuals being considered and reducing the likelihood of having the highest percentage. Choice C considers the combined staff of two hospitals, increasing the pool of individuals and making it more probable to have a higher percentage of doctors among the staff.

Correct Answer: C

Rationale: To solve the equation 3(x + 4) = 18 for x, first distribute the 3: 3x + 12 = 18. Then, isolate x by subtracting 12 from both sides: 3x = 6. Finally, divide by 3 to find x = 2. Therefore, the correct answer is x = 6. Choice A is incorrect because x = 2, not 6. Choice B is incorrect because x = 4, not 6. Choice D is incorrect because x = 8, not 6.

Correct Answer: A

Rationale: The correct answer is A: Shifts = (2)(5) + 4. 1. Nurse Cameron worked 5 shifts in week 1. 2. In week 2, she worked twice as many shifts as in week 1, which is 2 * 5 = 10 shifts. 3. In week 3, she added 4 shifts to the number of shifts worked in week 2, which is 10 + 4 = 14 shifts. 4. Therefore, the equation describing the number of shifts Nurse Cameron worked in week 3 is (2)(5) + 4 = 10 + 4 = 14 shifts. Summary of incorrect choices: B: Shifts = (4)(5) + 2 - Incorrect because it does not account for the doubling of shifts in week 2 and the addition of 4 shifts in week 3. C: Shifts = 5 + 2 + 4 - Incorrect as it

Correct Answer: B

Rationale: The correct answer is B: 1 centimeter. The average length of a human eyelash is around 1 centimeter. This length is suitable for protecting the eyes from debris and dust particles while allowing them to function properly. Choice A, 1 nanometer, is far too small for an eyelash. Choice C, 1 meter, and choice D, 1 kilometer, are both significantly longer than the actual length of a human eyelash, making them unrealistic and incorrect options.
