TEAS Practice Test Math

1. Which of the following is the correct decimal placement for the product of 1.6 * 0.93?

A. 14.88
B. 0.1488
C. 1.488
D. 0.001488

Correct answer: C

Rationale: To find the product of 1.6 * 0.93, you multiply these two numbers to get 1.488. Therefore, the correct decimal placement for the product is 1.488. Choice A, 14.88, is incorrect as it incorrectly places the decimal two spots to the right. Choice B, 0.1488, is incorrect as it incorrectly places the decimal one spot to the right. Choice D, 0.001488, is incorrect as it incorrectly places the decimal three spots to the right.

2. Which of the following options correctly orders the numbers below from least to greatest? 235.971, 145.884, -271.906, -193.823

A. -271.906, -193.823, 145.884, 235.971
B. -271.906, 235.971, -193.823, 145.884
C. 145.884, -193.823, 235.971, -271.906
D. -193.823, -271.906, 145.884, 235.971

Correct answer: A

Rationale: To correctly order the numbers from least to greatest, we start with the smallest number, which is -271.906, followed by -193.823, 145.884, and finally 235.971. Therefore, the correct order is -271.906, -193.823, 145.884, 235.971. Choice A is correct. Choice B is incorrect as it incorrectly places 235.971 before -193.823. Choice C is incorrect as it starts with the largest number, 145.884. Choice D is incorrect as it starts with -193.823, which is not the smallest number in the list.

3. Which of the following is important to do while writing the first draft of a research paper?

A. Listen to soothing music to create a relaxed writing environment.
B. Write the conclusion before writing the rest of the research paper.
C. Write the introduction, the body, and the conclusion of the project.
D. Check to ensure that all citations are accurate.

Correct answer: C

Rationale: When writing the first draft of a research paper, it is crucial to include the complete structure, which consists of the introduction, body, and conclusion. This approach helps in organizing your thoughts and ideas cohesively, ensuring that your paper flows logically. Choice A is not directly related to the drafting process. Choice B suggests an incorrect sequence by proposing to write the conclusion first, which should actually be crafted after the body of the paper. Choice D is important but typically done during the editing and revision stages rather than in the initial draft.

4. With which of the following statements would the author most likely agree?

A. There is no real mystery about the Bermuda Triangle because most events have reasonable explanations.
B. Researchers are wrong to expand the focus of the Triangle to the Azores, as this increases the likelihood of accidents.
C. The official statement of 'causes or reasons unknown' in the loss of the Navy planes was a deliberate concealment from the Navy.
D. Reducing the legends about the mysteries of the Bermuda Triangle will help to reduce the number of reported accidents or shipping losses in the region.

Correct answer: D

Rationale: The author would most likely agree with the statement that reducing the legends about the mysteries of the Bermuda Triangle will help to reduce the number of reported accidents or shipping losses in the region. This aligns with the perspective that many events in the Bermuda Triangle can be explained logically and that dispelling myths and legends can lead to a more accurate understanding of the phenomena occurring in the area. Choice A is incorrect because the author acknowledges that the Bermuda Triangle has sparked interest due to unexplained events. Choice B is incorrect as expanding the focus of the Triangle to the Azores is not associated with an increase in accidents, according to the author. Choice C is incorrect as the author does not suggest a deliberate concealment but rather points towards logical explanations for the events in the Bermuda Triangle.

5. What is the 'lock-and-key' model?

A. Protein folding
B. Enzyme-substrate interaction
C. Muscle contraction
D. Blood clotting

Correct answer: B

Rationale: The 'lock-and-key' model describes the specificity of the interaction between enzymes and their substrates. In this model, the enzyme's active site acts like a lock that can only be opened by the specific substrate molecule, which serves as the key. This specific binding ensures that enzymes catalyze particular reactions and do not interact with other molecules indiscriminately. Protein folding (option A) is the process by which a protein attains its functional three-dimensional structure but is not directly related to the lock-and-key model. Muscle contraction (option C) and blood clotting (option D) are complex biological processes but are not directly associated with the lock-and-key model of enzyme-substrate interaction.
