Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
What is the least common multiple (LCM) of 4 and 6?
Correct Answer: A
Rationale:
To find the least common multiple (LCM) of 4 and 6, we need to determine the smallest number that is a multiple of both 4 and 6. The multiples of 4 are: 4, 8, 12, 16, 20, 24, ... The multiples of 6 are: 6, 12, 18, 24, ... The least common multiple is the smallest number that appears in both lists. In this case, the least common multiple of 4 and 6 is 12, not 24.
Therefore, the correct answer is 24.
Choice B (12) is actually the least common multiple of 4 and 3, not 4 and 6.
Choices C (6) and D (3) are not multiples of both 4 and 6, so they are incorrect.
Question 3 of 5
If y = 4 and x = 3, solve y x³
Correct Answer: B
Rationale: With y = 4 and x = 3, the expression is y x³. Substituting the values, we get 4 3³ = 4 27 = 108.
Therefore, the correct answer is 108. Option A (-108) is incorrect because the negative sign is not part of the result. Option C (27) is incorrect as it only represents x³ without considering the value of y. Option D (4) is incorrect as it represents the initial value of y, not the result of y x³.
Question 4 of 5
What is 28% of 100?
Correct Answer: A
Rationale: The correct answer is A: 28.
To find 28% of 100, you multiply 0.28 (the decimal equivalent of 28%) by 100. This calculation results in 28.
Therefore, 28% of 100 is 28.
Choice B, 20, is incorrect as it represents 20% of 100.
Choice C, 25, is incorrect as it represents 25% of 100.
Choice D, 30, is incorrect as it represents 30% of 100.
Question 5 of 5
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.
