TEAS Practice Math Test
1. A rectangular solid box has a square base with a side length of 5 feet and a height of h feet. If the volume of the box is 200 cubic feet, which of the following equations can be used to find h?
- A. 5h = 200
- B. 5h² = 200
- C. 25h = 200
- D. h = 200 ÷ 5
Correct answer: C
Rationale: The volume formula for a rectangular solid is V = l × w × h. In this case, the length and width are both 5 feet. Substituting the values into the formula gives V = 5 × 5 × h = 25h = 200. Therefore, h = 200 ÷ 25 = 8. Option A is incorrect because the product of length, width, and height is not directly equal to the volume. Option B is incorrect as squaring the height is not part of the volume formula. Option D is incorrect as it oversimplifies the relationship between height and volume, not considering the base dimensions.
2. Which of the following describes a visual tool that a writer uses to diagram ideas around a central concept?
- A. Bar graph
- B. Citation
- C. Revision
- D. Mind map
Correct answer: D
Rationale: A mind map is a visual tool commonly used by writers to diagram ideas around a central concept. It helps in brainstorming and organizing thoughts by visually representing the relationships between different ideas. Choice A, a bar graph, is a graphical representation of data typically used to compare quantities. Choice B, a citation, is a reference to a source used in writing to give credit. Choice C, revision, refers to the act of reviewing, editing, and improving written work.
3. The phone bill is calculated each month using the equation C = 50 + 75D. The cost of the phone bill per month is represented by C, and D represents the gigabytes of data used that month. What is the value and interpretation of the slope of this equation?
- A. 75 dollars per gigabyte
- B. 75 gigabytes per day
- C. 50 dollars per day
- D. 50 dollars per gigabyte
Correct answer: A
Rationale: The slope of the equation C = 50 + 75D is 75. This means that for each additional gigabyte used (represented by D), the cost (represented by C) increases by 75 dollars. Therefore, the correct interpretation of the slope is that it is 75 dollars per gigabyte. Choice B, 75 gigabytes per day, is incorrect as the slope does not represent the rate of data usage per day. Choice C, 50 dollars per day, is incorrect as it does not reflect the relationship between gigabytes used and the cost. Choice D, 50 dollars per gigabyte, is incorrect as it does not match the slope value of 75 in the equation.
4. The patella, commonly known as the kneecap, is an example of a:
- A. Sesamoid bone
- B. Long bone
- C. Short bone
- D. Irregular bone
Correct answer: A
Rationale: The patella, also known as the kneecap, is an example of a sesamoid bone. Sesamoid bones develop within tendons, such as the patellar tendon in this case. The patella is embedded in the tendon of the quadriceps muscle, enhancing the mechanical advantage of the muscle and protecting the knee joint. Long bones, like the femur, are characterized by their elongated shape with growth plates at the ends. Short bones, such as those in the wrist and ankle, are cube-shaped bones. Irregular bones, like vertebrae, do not fit into the other bone shape categories due to their unique shapes and functions.
5. Which sentence uses the pronoun 'they' correctly?
- A. They is going to the park later today.
- B. Sarah and John said they would come to the party.
- C. The teacher said they needs to finish the report.
- D. They enjoys reading books in their free time.
Correct answer: B
Rationale: A. "They" should be used with "are," not "is." B. Correct use of "they" for multiple people (Sarah and John). C. "They" should not be paired with "needs." D. "They" should be used with "enjoy," not "enjoys."
