TEAS Test Math Questions Questions
Question 1 of 5
What is the perimeter of a square with a side length of 6 cm?
Correct Answer: A
Rationale: The perimeter of a square is calculated by multiplying the side length by 4 since all sides are equal. In this case, the side length is 6 cm, so the perimeter is 4 * 6 = 24 cm.
Therefore, choice A, 24 cm, is the correct answer.
Choices B, C, and D are incorrect because they do not reflect the correct calculation for the perimeter of a square.
Question 2 of 5
Simplify the expression 3x - 5x + 2.
Correct Answer: D
Rationale: When simplifying the expression 3x - 5x + 2, start by combining like terms. -5x is subtracted from 3x to give -2x. Adding 2 at the end gives the simplified expression -2x.
Therefore, the correct answer is -2x.
Choice A, -2x + 2, incorrectly adds 2 at the end.
Choice B, -8x, incorrectly combines the coefficients of x without considering the constant term.
Choice C, 2x + 2, incorrectly adds the coefficients of x without simplifying.
Question 3 of 5
What is the mode of the data set: 2, 3, 3, 4, 4, 4, 5?
Correct Answer: C
Rationale: The mode of a data set is the value that appears most frequently. In this data set (2, 3, 3, 4, 4, 4, 5), the number 4 appears three times, which is more frequent than any other number in the set.
Therefore, the correct answer is 4.
Choice A (2), B (3), and D (5) do not appear as frequently as 4 in the data set, so they are not the mode.
Question 4 of 5
If a tree grows an average of 4.2 inches in a day, what is the rate of change in its height per month? Assume a month is 30 days.
Correct Answer: D
Rationale: The tree grows at an average rate of 4.2 inches per day.
To find the rate of change per month, multiply the daily growth rate by the number of days in a month (30 days):
4.2 inches/day 30 days = 126 inches per month.
Therefore, the rate of change in the tree's height is 126 inches per month, making option D the correct answer. Option A is incorrect because it miscalculates the rate based on daily growth. Option B is incorrect as it doesn't account for the total days in a month. Option C is incorrect as it overestimates the monthly growth rate.
Question 5 of 5
A piece of wood that is 7 1/2 feet long has 3 1/4 feet cut off. How many feet of wood remain?
Correct Answer: A
Rationale:
To find the remaining length of wood, you need to subtract 3 1/4 feet from 7 1/2 feet. When you subtract the fractions, 7 1/2 - 3 1/4, you get 15/2 - 13/4 = 30/4 - 13/4 = 17/4 = 4 1/4 feet.
Therefore, the correct answer is 4 1/4 feet.
Choice B (4 1/2 feet) is incorrect because the subtraction result is not 1/2.
Choice C (3 1/2 feet) is incorrect as it does not match the correct result of 4 1/4 feet.
Choice D (3 3/4 feet) is also incorrect as it does not align with the correct answer obtained from the subtraction of fractions.
