TEAS Test Math Questions Questions
Question 1 of 5
Solve |x| = 10.
Correct Answer: A
Rationale: The absolute value of x is equal to 10 when x is either -10 or 10.
Therefore, the correct answer is A.
Choices B, C, and D are incorrect because they do not satisfy the equation |x| = 10. For choice B, -11 and 11 do not satisfy the condition.
Choices C and D also do not provide solutions that meet the equation's requirement.
Question 2 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 3 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 4 of 5
What is the difference between two negative numbers?
Correct Answer: B
Rationale: The correct answer is B: 'Positive number.' When you subtract one negative number from another negative number, the result can be a positive number. For example, the difference between -5 and -3 is 2, which is a positive number.
Choice A, 'Negative number,' is incorrect because the result of subtracting two negative numbers can be positive.
Choice C, 'Zero,' is incorrect because the difference between two negative numbers is not always zero.
Choice D, 'Not enough information,' is incorrect because there is enough information to determine that the difference between two negative numbers can be a positive number.
Question 5 of 5
How much hydrochloric acid (HCl) is necessary to make 2.5 liters of a 5:1 solution of water (in liters) to HCl (in grams)?
Correct Answer: C
Rationale:
To create a 5:1 solution in 2.5 liters, 0.5 liters are needed for HCl, which translates to 5 grams. The correct answer is 5 grams, as this amount corresponds to the 5:1 ratio specified in the solution.
Choices A, B, and D are incorrect because they do not align with the 5:1 ratio and the volume of the solution.
