TEAS Test Practice Math

1. What is the square root of 1296?

A. 24
B. 36
C. 31
D. 12

Correct answer: B

Rationale: The square root of 1296 is 36 because 36 multiplied by 36 equals 1296. Therefore, the correct answer is 36. Choices A, C, and D are incorrect. A (24) is not the square root of 1296 because 24 multiplied by 24 is 576, not 1296. C (31) is also incorrect as 31 multiplied by 31 is 961, not 1296. D (12) is not the square root of 1296 as 12 multiplied by 12 equals 144, not 1296.

2. Which of the following sentences has correct pronoun-antecedent agreement?

A. The storm, which included three days of rain, was very strong, and it left half the city flooded.
B. Each of the cars needs to be examined for damage by a mechanic; they may need repairs.
C. The number of people who had to evacuate hasn’t been confirmed, but it is small.
D. Many people were able to take advantage of shelters, where they were kept safe from the storm.

Correct answer: C

Rationale: Sentence C correctly maintains the pronoun-antecedent agreement. In this sentence, the antecedent is 'number of people,' and the pronoun 'it' is used to refer back to this antecedent. The singular pronoun 'it' matches the singular antecedent 'number,' making the sentence grammatically correct. Choice A is incorrect because it uses the plural pronoun 'they' to refer back to the singular antecedent 'storm.' Choice B is incorrect as it uses the plural pronoun 'they' to refer back to the singular antecedent 'each of the cars.' Choice D is incorrect because it uses the singular pronoun 'he or she' to refer back to the plural antecedent 'many people.' This creates a lack of agreement between the pronoun and its antecedent.

3. Which of the following structures in the body is responsible for protecting the lungs and heart?

A. Rib cage
B. Pelvis
C. Femur
D. Vertebral column

Correct answer: A

Rationale: The rib cage is the correct answer. It plays a crucial role in protecting vital organs like the lungs and heart. The rib cage forms a protective barrier around these organs, shielding them from external trauma or injuries. It acts as a sturdy cage, offering structural support and safeguarding the delicate tissues and structures of the lungs and heart. The pelvis, femur, and vertebral column do not directly protect the lungs and heart; instead, they have other important functions in the body, such as supporting the body's weight, enabling movement, and protecting the spinal cord.

4. Which of the following describes an experiment?

A. The final math grades for a group of students passing through each year of elementary school are examined.
B. The health trends of smokers in a small random sample are examined.
C. Citizens in a local community are surveyed to determine concerns related to the next election.
D. The effects of a new drug are tested on a group of participants.

Correct answer: D

Rationale: Option D describes an experiment because it involves testing the effects of a new drug on a group of participants. In an experiment, researchers intentionally manipulate an independent variable (in this case, the new drug) to observe its effects on a dependent variable (the participants' health outcomes). This method allows for establishing cause-and-effect relationships between variables, which is a key characteristic of experimental research design. Choices A, B, and C do not represent experiments. Choice A involves observational analysis of math grades, choice B involves observational analysis of health trends, and choice C involves a survey, none of which involve manipulating variables to establish cause-and-effect relationships.

5. What property of a wave determines the loudness of sound when heard by the human ear?

A. Frequency
B. Amplitude
C. Wavelength
D. Velocity

Correct answer: B

Rationale: The amplitude of a wave determines the loudness of sound when heard by the human ear. The greater the amplitude of a sound wave, the louder the sound will be perceived. Frequency (Choice A) refers to the number of wave cycles in a given time period. Wavelength (Choice C) is the distance between two corresponding points on a wave. Velocity (Choice D) is the speed at which the wave travels and does not directly affect the loudness of sound perceived by the human ear.
