TEAS Math Practice Test

1. If Mom's car drove 72 miles in 90 minutes, how fast did she drive in feet per second?

A. 0.8 feet per second
B. 48.9 feet per second
C. 0.009 feet per second
D. 70.4 feet per second

Correct answer: D

Rationale: To convert miles per hour to feet per second, first convert time to hours: 90 minutes = 1.5 hours. Then, calculate the speed in miles per hour: 72 miles in 1.5 hours = 48 mph. Finally, convert mph to feet per second using the conversion factor 1 mph = 1.47 feet per second: 48 mph * 1.47 = 70.4 feet per second. Therefore, the correct answer is 70.4 feet per second. Choices A, B, and C are incorrect because they do not reflect the correct conversion from miles per hour to feet per second.

2. After graduating from Proviso East High School in 1966, he later went on to study law at Triton Junior College. Which of these sentences, if any, should begin a new paragraph?

A. There should be no new paragraph.
B. After graduating from Proviso East High School in 1966, he later went on to study law at Triton Junior College.
C. While studying at Triton, Hampton joined and became a leader of the National Association for the Advancement of Colored People (NAACP).
D. As a result of his leadership, the NAACP gained more than 500 members.

Correct answer: B

Rationale: The sentence 'After graduating from Proviso East High School in 1966, he later went on to study law at Triton Junior College' marks a shift in the narrative as it introduces a new stage in the individual's journey. This change in focus warrants starting a new paragraph to clearly separate different events or developments in the person's life. Choices C and D are related to Hampton's actions during or after his time at Triton College but do not necessitate a new paragraph. Choice A is incorrect because the sentence provided is a suitable candidate for starting a new paragraph due to the change in the main topic it introduces.

3. What mnemonic helps in recalling metric conversions?

A. King Hector Died By Drinking Chocolate Milk
B. Kittens Have Delighted By Dancing Cool Moves
C. Memorize Your Units Well
D. Convert These Every Time

Correct answer: A

Rationale: The mnemonic 'King Hector Died By Drinking Chocolate Milk' aids in recalling metric prefixes in order: kilo-, hecto-, deca-, base (meter, liter, gram), deci-, centi-, milli-. Choice B does not provide a relevant mnemonic for metric conversions. Choices C and D do not offer a helpful phrase for remembering metric prefixes, making them incorrect.

4. Which of the following hormones is responsible for regulating blood sugar levels?

A. Insulin
B. Adrenaline
C. Cortisol
D. Melatonin

Correct answer: A

Rationale: Insulin is the hormone responsible for regulating blood sugar levels by facilitating the uptake of glucose into cells. Insulin helps lower blood sugar levels by promoting the storage of glucose in the liver, muscle, and fat cells. Adrenaline, cortisol, and melatonin do not directly regulate blood sugar levels. Adrenaline is involved in the fight-or-flight response, cortisol is a stress hormone that affects metabolism, immune response, and anti-inflammatory actions, while melatonin regulates sleep-wake cycles.

5. What is a quotient?

A. The result of dividing two numbers
B. The result of multiplying two numbers
C. The number left after subtraction
D. The number remaining after a division

Correct answer: A

Rationale: A quotient is the result of dividing one number by another. Choice A is correct because it accurately defines a quotient as the outcome of a division operation. Choice B is incorrect because it describes the result of multiplying two numbers, not dividing them. Choice C is incorrect because it refers to the remainder of a subtraction operation, not a division. Choice D is incorrect because it mentions the number remaining after a division, which is typically referred to as the remainder and not the quotient.
