TEAS Math Questions

Correct Answer: B

Rationale: Step 1: Calculate the number of boys in the class. 60% of 30 students = 0.6 * 30 = 18 boys. Step 2: Calculate the number of girls in the class. Since there are 30 students in total, and 18 are boys, there must be 30 - 18 = 12 girls. Therefore, the correct answer is B: 12 girls. Other choices are incorrect because they do not align with the given percentages and total number of students.

Correct Answer: C

Rationale: The correct answer is C: 6 hours. To calculate the total time taken, we first find the time taken for the first leg of the journey: 300 miles at 60 mph = 300/60 = 5 hours. Then, for the second leg: 200 miles at 80 mph = 200/80 = 2.5 hours. Adding these two times gives us 5 + 2.5 = 7.5 hours. Since there was a 30-minute break during the trip, we subtract this break time from the total, giving us 7.5 - 0.5 = 7 hours. Therefore, the correct answer is 6 hours. Choice A (5.5 hours) is incorrect because it does not account for the break time. Choice B (7 hours) is incorrect because it does not consider the total time with the break. Choice D (4.5 hours) is incorrect as it does not accurately calculate the total time

Correct Answer: B

Rationale: To solve the expression, follow the order of operations (PEMDAS). First, multiply 2 by 8 to get 16. Then, add -3 and 16 to get 13. Finally, add 3 to 13 to get 16. Therefore, the correct answer is 13. Choice A (11) is incorrect because it does not account for the correct order of operations. Choice C (28) is incorrect as it only considers the addition of -3 and 3. Choice D (80) is incorrect as it wrongly multiplies 2 by 8 before adding -3.

Correct Answer: C

Rationale: To find how many questions the student answered correctly: 1. Calculate 85% of 50: 0.85 * 50 = 42.5 2. Since the student can't answer half a question, round down to the nearest whole number: 42 Therefore, the student answered 42 questions correctly. Option C is correct. Incorrect options: A: 40 questions - Too low, as the student scored above 40. B: 42 questions - Close but not rounded correctly. D: 45 questions - Too high, as the student's score was 85%.

Correct Answer: C

Rationale: To calculate the total time, first find the time for the first segment: 305 miles / 65 mph = 4.69 hours. Then, add the 15-minute stop: 15 minutes / 60 = 0.25 hours. Next, find the time for the second segment: 162 miles / 80 mph = 2.025 hours. Add up all the times: 4.69 + 0.25 + 2.025 = 6.965 hours. Since this is closest to 6.69 hours (choice C), that is the correct answer. Choices A, B, and D are incorrect because they do not accurately represent the total time elapsed since the trip began.
