TEAS Exam Math Practice Questions
Question 1 of 5
Melissa is ordering fencing to enclose a square area of 5625 square feet. How many feet of fencing does she need?
Correct Answer: C
Rationale: To find the perimeter of the square, we first need to find the side length. Since the area of a square is side length squared (5625 = side length x side length), the side length is √5625 = 75 feet. The perimeter of a square is 4 times the side length, so 4 x 75 = 300 feet. Therefore, Melissa needs 300 feet of fencing. Summary: A) 75 feet - Incorrect. This is the side length, not the perimeter. B) 150 feet - Incorrect. This is half the perimeter. C) 300 feet - Correct. The perimeter of the square. D) 5,625 feet - Incorrect. This is the total area, not the perimeter.
Question 2 of 5
What is the result of (4.71 10^3) - (2.98 10^2)? Which of the following is the correct simplified expression?
Correct Answer: D
Rationale: To subtract numbers in scientific notation, we need to ensure the exponents are the same. First, convert 2.98 x 10^2 to 0.298 x 10^3. Then, subtract 4.71 x 10^3 - 0.298 x 10^3 = 4.412 x 10^3. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the correct result of the subtraction operation.
Question 3 of 5
Based on a favorable performance review at work, Matt receives a 3/20 increase in his hourly wage. If his original hourly wage is represented by w, which of the following represents his new wage?
Correct Answer: D
Rationale: To calculate Matt's new wage, we need to add the 3/20 increase to his original wage w. So, the new wage is w + 3/20w = 23/20w = 1.15w, which corresponds to choice D. Choice A is incorrect as it represents a decrease. Choice B is incorrect as it represents a smaller increase. Choice C is incorrect as it represents a larger increase than what Matt received.
Question 4 of 5
Adam is painting the outside of a 4-walled shed. The shed is 5 feet wide, 4 feet deep, and 7 feet high. Which of the following is the amount of paint Adam will need for the four walls?
Correct Answer: B
Rationale: Failed to generate a rationale after 5 retries.
Question 5 of 5
After taxes, a worker earned $15,036 in 7 months. What is the amount the worker earned in 2 months?
Correct Answer: B
Rationale: To find the amount earned in 2 months, divide the total earned in 7 months by 7 to get the monthly amount. $15,036 / 7 = $2,148 earned per month. Then, multiply this monthly amount by 2 to find the earnings in 2 months: $2,148 * 2 = $4,296. Therefore, choice B ($4,296) is correct. Choices A, C, and D are incorrect because they do not follow the correct calculation steps and do not result in the accurate amount earned in 2 months.
