TEAS Test Sample Math Questions Questions
Question 1 of 5
What is the domain for the function f(x)=2x+5?
Correct Answer: A
Rationale: The domain of a function represents all possible input values that the function can accept. In this case, the function f(x)=2x+5 is a linear function, and linear functions have a domain of all real numbers. This means that any real number can be substituted for x in the function f(x)=2x+5, making choice A, 'All real numbers,' the correct domain for this function. Choices B, C, and D, restrict the domain unnecessarily by limiting the values of x to specific subsets of real numbers, which does not accurately reflect the nature of the given function.
Question 2 of 5
What is the value of the sum of 0.75 and 0.625?
Correct Answer: B
Rationale: In this math question from the TEAS Test Sample, the correct answer is B) 1.375. To find the sum of 0.75 and 0.625, you simply add the two numbers together. When you add 0.75 and 0.625, you get 1.375. Option A) 0.875 is incorrect because it is the sum of 0.75 and 0.125, not 0.625 as given in the question. Option C) 1.625 is incorrect because it is the sum of 1.0 and 0.625, not 0.75 as provided. Option D) 0.125 is incorrect as it is the difference between 0.75 and 0.625, not the sum. Educationally, this question tests your ability to perform basic arithmetic operations involving decimals. Understanding how to add decimals is a fundamental math skill that is essential for various real-life applications, including budgeting, shopping, and calculating measurements. Practicing these types of questions can help improve your math fluency and problem-solving skills.
Question 3 of 5
What is the product of two irrational numbers?
Correct Answer: C
Rationale: The correct answer is C: 'Irrational or rational.' When you multiply two irrational numbers, the result can be either irrational or rational. For example, multiplying the square root of 2 (√2) by itself results in the rational number 2. This shows that the product of two irrational numbers can lead to a rational result. Choices A, B, and D are incorrect because the product of two irrational numbers is not limited to being irrational; it can also be rational.
Question 4 of 5
A closet is filled with red, blue, and green shirts. If 2/5 of the shirts are green and 1/3 are red, what fraction of the shirts are blue?
Correct Answer: C
Rationale: To find the fraction of blue shirts, subtract the fractions of green and red shirts from 1. Green shirts are 2/5 and red shirts are 1/3, which sum up to 11/15. Therefore, blue shirts would be 1 - 11/15 = 4/15. So, the correct answer is 4/15. Choice A (4/15) is incorrect as it represents the overall fraction of green shirts. Choice B (1/5) is incorrect as it does not account for the fractions of green and red shirts. Choice D (1/2) is incorrect as it does not consider the given fractions of green and red shirts.
Question 5 of 5
Shawna buys 5.0 gallons of paint. If she uses 2.5 gallons of it on the first day, how much does she have left?
Correct Answer: B
Rationale: To find the remaining paint, subtract the amount used from the total gallons bought. 5.0 - 2.5 = 2.5 gallons. Therefore, Shawna has 2.5 gallons of paint left after using 2.5 gallons on the first day. Choices A, C, and D are incorrect because they do not accurately represent the amount of paint left after using 2.5 gallons.
