TEAS Practice Math Test Questions
Question 1 of 5
What is the number of students who said their favorite color is blue if 35% of 100 students chose blue as their favorite color?
Correct Answer: A
Rationale:
To find the number of students who said their favorite color is blue, we calculate 35% of 100, which is (35/100) * 100 = 35.
Therefore, 35 students said their favorite color is blue.
Choice B is incorrect because it represents the percentage of students who chose red.
Choice C is incorrect as it represents the percentage of students who chose green.
Choice D is incorrect as it represents the percentage of students who chose yellow.
Question 2 of 5
The number of vacuum cleaners sold by a company per month during Year 1 is listed below: 18, 42, 29, 40, 24, 17, 29, 44, 19, 33, 46, 39. Which of the following is true?
Correct Answer: D
Rationale: The mean number of vacuum cleaners sold per month is 31.7, the mode is 29, the median is 31, and the range is 29. The mode being equal to the range is the correct statement. Option A is incorrect because the mean (31.7) is greater than the median (31). Option B is incorrect as the mode (29) is not greater than the median (31). Option C is incorrect since the mode (29) is not less than the mean, median, or range.
Question 3 of 5
Jeremy put a heavy chalk mark on the tire of his bicycle. His bike tire is 27 inches in diameter. When he rolled the bike, the chalk left marks on the sidewalk. Which expression can be used to best determine the distance, in inches, the bike rolled from the first mark to the fourth mark?
Correct Answer: A
Rationale: The distance traveled by the bike in one complete roll of the tire is equal to the circumference, which can be calculated using the formula C = πd, where d is the diameter. Given that the diameter of the bike tire is 27 inches, the circumference is obtained by multiplying the diameter by π. As the tire rolls from the first mark to the fourth mark, it completes three full rotations (one complete roll plus two more).
Therefore, the total distance rolled is 3 times the circumference, which results in 3(27π).
Choice A is correct.
Choice B is incorrect as it incorrectly multiplies the diameter by 4π instead of multiplying the circumference by 4.
Choices C and D are incorrect as they involve dividing the diameter by a number, which is not applicable in this context.
Question 4 of 5
A farmer had about 150 bags of potatoes on his trailer. Each bag contained from 23 to 27 pounds of potatoes. What is the best estimate of the total number of pounds of potatoes on the farmer's trailer?
Correct Answer: B
Rationale:
To estimate the total number of pounds of potatoes on the farmer's trailer, we can use the average weight of a bag of potatoes. The average weight is calculated by adding the minimum and maximum weights of the bags and dividing by 2: (23 + 27) / 2 = 25 pounds. Next, multiply the average weight by the total number of bags: 25 pounds/bag * 150 bags = 3,750 pounds.
Therefore, the best estimate of the total number of pounds of potatoes on the farmer's trailer is 3,750 pounds.
Choice A (3,000 pounds) is too low as it underestimates the total weight.
Choice C (4,100 pounds) and
Choice D (5,000 pounds) are too high as they overestimate the total weight.
Question 5 of 5
Which of the following describes a proportional relationship?
Correct Answer: A
Rationale: A proportional relationship is one in which two quantities vary directly with each other. In choice A, the amount deposited per month is directly proportional to the initial deposit. The relationship can be represented as y = 125x + 150, where x is the number of months and y is the total amount in the account.
Choices B and C involve additional fixed amounts or variable costs that do not maintain a constant ratio, making them non-proportional relationships.
Choice D refers to a constant speed of driving, which is not a proportional relationship as it does not involve varying quantities that change in direct proportion.
