(3, 3)
- C.
(2, 2)
- D.
(1, 1)
Correct Answer
A. (0, 0)Explanation

What is the least common denominator of 2/3 and 5/6?
- A.
3
- B.
18
- C.
6
- D.
12
Correct Answer
C. 6Explanation
The least common denominator is the smallest multiple that both denominators (3 and 6) can evenly divide into. In this case, the least common denominator is 6 because both 3 and 6 can evenly divide into 6. This means that if we convert 2/3 and 5/6 to fractions with a denominator of 6, we can compare them more easily.Rate this question:

- B.
1/9 And -1/9
- C.
1/9 And -9
- D.
1/9 And 9/1
Correct Answer
C. 1/9 And -9Explanation
If two lines are perpendicular, their slopes are negative reciprocals of each other. The slope of the first line is 1/9, and the slope of the second line is -9. Since -9 is the negative reciprocal of 1/9, these slopes satisfy the condition for perpendicular lines.Rate this question:

What is the median of 2, 4, 6, 8, 10, 12?
- A.
8
- B.
6 To 8

Correct Answer
C. 7Explanation
The median is the middle value when the numbers are arranged in ascending order. In this case, when the numbers 2, 4, 6, 8, 10, 12 are arranged in ascending order, the middle value is 8. However, since there is an even number of values, there are two middle values, which are 6 and 8. To find the median of the given numbers, we take the average of these two middle values, which is 7.Rate this question:
