HESI A2 Quizlet Math

1. If Mr. Johnson gives half of his pay to his family, $250 to his landlord, and has exactly 3/7 of his pay left over, how much pay does he receive?

Correct answer: B

Rationale: Let Mr. Johnson's pay be represented as x. After giving half of his pay to his family, he has x/2 left. Subtracting $250 paid to his landlord, he has x/2 - $250 remaining. Given that this remaining amount is 3/7 of his original pay, the equation becomes x/2 - $250 = 3x/7. Solving this equation shows that x = $3,500. Therefore, Mr. Johnson receives $3,500. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the given conditions in the question.

2. What is the meaning of Collusion?

Correct answer: B

Rationale: The correct answer is B: 'Conspiracy.' Collusion refers to a secret agreement or conspiracy, often for deceitful or illegal purposes. Choice A, 'Cooperation,' is incorrect as collusion implies a deceptive or dishonest agreement, not a genuine cooperation. Choice C, 'Separation,' is incorrect as it denotes the opposite of collusion, which involves working together secretly. Choice D, 'Rejection,' is unrelated to collusion, which involves secret cooperation for deceptive purposes.

3. If bacteria are placed in a strong solution of salt water, they will shrink as water moves out of the bacteria. What is this process called?

Correct answer: C

Rationale: Osmosis is the process by which water molecules move across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. In this case, when bacteria are placed in a strong solution of salt water, the high concentration of solutes outside the bacteria causes water to move out of the bacteria, leading to shrinkage. This process is known as osmosis. Dehydration synthesis (Choice A) is a process where molecules combine by removing water. Hydrolysis (Choice B) is the breakdown of molecules by the addition of water. Isotonic transport (Choice D) does not accurately describe the specific movement of water in or out of bacterial cells in a hypertonic solution.

4. Why doesn’t a raindrop accelerate as it approaches the ground?

Correct answer: B

Rationale: The correct answer is B. As a raindrop falls, it experiences air resistance which counteracts the gravitational force pulling it down. This balancing of forces prevents the raindrop from accelerating further as it approaches the ground. Choice A is incorrect because while gravity is pulling the raindrop down, air resistance opposes this force. Choice C is incorrect as the mass of the raindrop remains constant during its fall. Choice D is incorrect because objects in motion may decelerate due to various factors, but in this case, the focus is on why the raindrop doesn't accelerate.

5. Choose the meaning of the word "laceration" in the following sentence: "The accident left her with a painful laceration."

Correct answer: B

Rationale: In the sentence, "laceration" is referring to a deep cut or tear in the skin. It is often associated with injuries that are caused by sharp objects or trauma. Therefore, the most appropriate meaning of "laceration" in this context is a cut.
