TEAS Test Sample Math Questions Questions
Question 1 of 5
The phone bill is calculated each month using the equation y = 50x. The cost of the phone bill per month is represented by y and x represents the gigabytes of data used that month. What is the value and interpretation of the slope of this equation?
Correct Answer: D
Rationale: The slope of the equation y = 50x represents the rate of change in cost (y) per unit change in data usage (x). In this case, the slope is 50 dollars per gigabyte. This means that for every additional gigabyte of data used, the cost of the phone bill increases by $50. Explanation for other choices: A: 75 dollars per day - Incorrect. The equation does not involve time (days). B: 75 gigabytes per day - Incorrect. The slope represents cost per gigabyte, not gigabytes per day. C: 50 dollars per day - Incorrect. The slope is not based on a daily rate.
Question 2 of 5
Divide 4/3 by 9/13 and reduce the fraction.
Correct Answer: A
Rationale: To divide fractions, we multiply the first fraction by the reciprocal of the second. So, (4/3) ÷ (9/13) = (4/3) x (13/9) = 52/27. The correct answer is A, 52/27, as it follows the correct procedure of dividing fractions. The other choices are incorrect because they do not result from the proper operation of dividing fractions.
Question 3 of 5
Mom's car drove 72 miles in 90 minutes. How fast did she drive in feet per second?
Correct Answer: B
Rationale: To calculate speed in feet per second, we need to convert miles to feet and minutes to seconds. 72 miles = 72 * 5280 feet. 90 minutes = 90 * 60 seconds. Speed = distance / time. So, speed = (72 * 5280) / (90 * 60) = 48.9 feet per second. Therefore, choice B is correct. Choice A is too slow, choice C is extremely slow, and choice D is too fast when compared to the calculated speed.

The equation does not involve time (days). B: 75 gigabytes per day - Incorrect. The slope represents cost per gigabyte, not gigabytes per day. C: 50 dollars per day - Incorrect. The slope is not based on a daily rate.
