TEAS 7 Math Practice Test

1. Simplify the following expression: 5 x 3 ÷ 9 x 4

Correct answer: A

Rationale: To simplify the expression 5 x 3 ÷ 9 x 4, first perform the multiplications and divisions from left to right: 5 x 3 = 15 and 9 x 4 = 36. So, the expression becomes 15 ÷ 36. When dividing fractions, multiply the first fraction by the reciprocal of the second fraction. Hence, 15 ÷ 36 = 15/36. To simplify the fraction further, find the greatest common divisor, which is 3. Divide both the numerator and denominator by 3 to get the final result: 15/36 = 5/12. Therefore, the correct answer is A. Choices B, C, and D are incorrect because they do not represent the correct simplification of the given expression.

2. In the sentence, 'The receptionist explained that we would be the next to see the doctor,' which of the following is the complete predicate?

Correct answer: A

Rationale: The complete predicate is 'explained that we would be the next to see the doctor.' In a sentence, the complete predicate includes the main verb (explained) and all the words that complete its meaning (that we would be the next to see the doctor). Choices B, C, and D do not constitute the complete predicate as they do not include the main verb 'explained' and all associated words that complete its meaning.

3. What is the valve that prevents blood from flowing back from the left ventricle into the left atrium?

Correct answer: B

Rationale: The correct answer is the Mitral valve. The mitral valve is located between the left atrium and the left ventricle of the heart. Its function is to prevent the backflow of blood from the left ventricle into the left atrium during ventricular contraction. Choice A, the Tricuspid valve, is incorrect as it is located between the right atrium and right ventricle. Choice C, the Aortic valve, and Choice D, the Pulmonic valve, are also incorrect as they are involved in the circulation of blood leaving the heart rather than preventing backflow within the atria and ventricles.

4. What can one reasonably conclude from the final comment of this passage?

Correct answer: D

Rationale: The final comment in the passage indicates that Mr. Utterson intends to keep searching for Mr. Hyde, showing his determination. The passage describes how Mr. Utterson is troubled by questions about Hyde, engaging not just his intellect but also his imagination. Despite the lack of information obtained from Lanyon, Mr. Utterson continues to ponder the problem late into the night, suggesting his commitment to uncovering the mystery. Choices A, B, and C are incorrect because there is no indication in the passage that the speaker is considering a name change, experiencing an identity crisis, or mistakenly looking for the wrong person. The passage focuses on Mr. Utterson's persistent search for Hyde, emphasizing his unwavering resolve.

5. A person wakes up with a fever. The body begins its response to locate the origin of the problem and fix it. What type of feedback mechanism is this?

Correct answer: B

Rationale: This scenario describes a negative feedback mechanism. When the body detects a fever, it initiates responses to lower the temperature back to normal levels. Negative feedback mechanisms work to counteract changes and maintain homeostasis in the body. Choice A ('Equal') is incorrect as feedback mechanisms aim to restore balance, not maintain an equal state. Choice C ('Neutral') is incorrect as it does not describe the corrective nature of negative feedback. Choice D ('Positive') is incorrect as it would amplify the fever rather than regulate it.
