TEAS Math Questions Questions
Question 1 of 5
Complete the following equation: x + x * x - x / x = ?
Correct Answer: B
Rationale:
To solve the equation x + x * x - x / x, follow the order of operations (PEMDAS/BODMAS). First, perform the multiplication: x * x = x^2.
Then, perform the division: x / x = 1. Substituting these back into the equation gives x + x^2 - 1.
Therefore, the equation simplifies to x + x^2 - 1. By evaluating this further, the final result is 3.
Choices A, C, and D are incorrect because they do not correctly apply the order of operations to solve the equation.
Question 2 of 5
What is the range in the number of flights made per month by the flight attendant?
Correct Answer: C
Rationale: The range is calculated by finding the difference between the highest and lowest values. In this case, the highest number of flights made per month is 32, and the lowest is 3.
Therefore, the range is 32 - 3 = 29.
Choice C, '29', is the correct answer.
Choice A, '20',
Choice B, '25', and
Choice D, '32', are incorrect as they are individual data points and do not represent the range, which is a measure of spread between the highest and lowest values.
Question 3 of 5
If 3/4 of students at a university major in nursing and 1/3 of those students complete the program, how many will complete the program if 100 students are in the incoming class?
Correct Answer: C
Rationale: Out of the 100 students, 3/4 (75 students) major in nursing. Since 1/3 of those students complete the program, 1/3 * 75 = 25 students will complete the program.
Therefore, 25 students out of the 100 incoming class will complete the program, making choice C (15) the correct answer.
Choices A, B, and D are incorrect as they do not reflect the correct calculation based on the given information.
Question 4 of 5
A person drives 300 miles at 60 mph, then another 200 miles at 80 mph, with a 30-minute break. How long does the trip take?
Correct Answer: C
Rationale:
To find the total time, we calculate the time taken for each segment: 300 miles at 60 mph = 300 miles · 60 mph = 5 hours; 200 miles at 80 mph = 200 miles · 80 mph = 2.5 hours. Adding these gives 5 hours + 2.5 hours = 7.5 hours. Converting the 30-minute break to hours (30 minutes · 60 = 0.5 hours), the total time taken is 7.5 hours + 0.5 hours = 8 hours.
Therefore, the correct answer is not among the given choices. The rationale provided in the original question is incorrect as it does not account for the break time and has a calculation error in adding the individual times.
Question 5 of 5
A charter bus driver drove at an average speed of 65 mph for 305 miles. If he stops at a gas station for 15 minutes, then drives another 162 miles at 80 mph, how long will it have been since he began the trip?
Correct Answer: C
Rationale:
To calculate the total time, first find the time for the first leg of the trip: 305 miles / 65 mph = 4.69 hours.
Then, add the time for the second leg: 162 miles / 80 mph = 2.025 hours. Next, add the 15-minute stop in hours (15 minutes = 0.25 hours). Finally, add the times together: 4.69 hours + 2.025 hours + 0.25 hours = 6.965 hours, which rounds to 6.69 hours.
Therefore, the correct answer is 6.69 hours.
Choice A is incorrect because it does not account for the total driving time correctly.
Choice B is incorrect as it does not include the time for the gas station stop.
Choice D is wrong as it miscalculates the total time taken for the trip.
