TEAS Practice Test Math Questions
Question 1 of 5
Which of the following is the most likely weight of a pencil?
Correct Answer: D
Rationale: In the TEAS Practice Test Math question asking for the most likely weight of a pencil, the correct answer is D) 25 g. This is the correct choice because grams (g) are the standard unit of measurement for small objects like a pencil. In the context of weight, grams are used to measure lightweight items accurately. Option A) 25 kg is incorrect because kilograms are used for much larger and heavier items, like a person or a large sack of potatoes. Option B) 25 cm is incorrect because centimeters are a unit of length, not weight. Option C) 25 mg is incorrect as milligrams are used for very small and light items, such as medication dosage or fine powders. Educationally, understanding units of measurement is crucial for practical applications in math and science. Students need to grasp the appropriate unit for measuring weight to ensure accuracy and precision in calculations. This question helps reinforce the concept of selecting the correct unit based on the object being measured, enhancing students' critical thinking and problem-solving skills.
Question 2 of 5
What is the area of the largest circle that can fit entirely inside a rectangle that measures 8 centimeters by 10 centimeters?
Correct Answer: C
Rationale: The largest circle that can fit inside the rectangle would have a diameter of 8 cm, which means the radius is half of the diameter, thus 4 cm. The area of a circle is calculated using the formula A = πr², where r is the radius. Substituting the radius value into the formula, the area of the circle is π(4)² = 16π cm². Therefore, the correct answer is 16π cm². Choice A (18π cm²), B (10π cm²), and D (8π cm²) are incorrect because they do not represent the area of the largest circle that fits inside the given rectangle.
Question 3 of 5
A consumer makes a $400 down payment on a television that costs $1,570. Which of the following is the number of months it will take to pay off the television with monthly payments of $100?
Correct Answer: A
Rationale: After the $400 down payment, the remaining balance is $1,170. With monthly payments of $100, it will take 12 months to pay off the remaining balance. Therefore, the correct answer is 12 months. Choice B (16) is incorrect as it exceeds the required timeframe. Choice C (15) is incorrect as it is close but still one month over the correct timeframe. Choice D (11) is incorrect as it underestimates the time needed to pay off the remaining balance.
Question 4 of 5
Which of the following statements demonstrates a negative correlation between two variables?
Correct Answer: C
Rationale: The correct answer is C. This statement demonstrates a negative correlation between two variables as it indicates that as tennis balls age, their bounce tends to decrease. In a negative correlation, as one variable increases, the other tends to decrease. Choices A, B, and D do not illustrate a negative correlation. Choice A describes a positive correlation, as playing baseball more is associated with having more hits. Choice B does not show a correlation but a general observation. Choice D also does not demonstrate a correlation; it simply states that older cars tend to have higher mileage, without implying a relationship between age and mileage.
Question 5 of 5
The hypotenuse (side C) of a triangle is 13 inches long. Which of the following pairs of measurements could be correct for the lengths of the other two sides of the triangle? (Note: A² + B² = C²)
Correct Answer: A
Rationale: The correct answer is A. Using the Pythagorean theorem (A² + B² = C²), we substitute the values: 5² + 12² = 13². This simplifies to 25 + 144 = 169, which is true. Therefore, 5 inches and 12 inches could be the lengths of the other two sides. Choices B, C, and D do not satisfy the Pythagorean theorem, making them incorrect options.
