18

6

12

3

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.

9. Which number is to the left of -3 on the number line?

0

-1

3

-4

The number to the left of -3 on the number line is -4. This is because -4 is a smaller number than -3 and is located to the left of -3 on the number line.

Explanation

The number to the left of -3 on the number line is -4. This is because -4 is a smaller number than -3 and is located to the left of -3 on the number line.

10. What is the coordinate of the origin?

(3, 3)

(2, 2)

(1, 1)

(0, 0)

The coordinate of the origin is (0, 0) because the origin is defined as the point where the x-axis and y-axis intersect, and at this point, both x and y coordinates are zero.

11. What is 1/4 + 1/2?

8-Mar

2-Feb

4-Mar

6-Feb

The given question asks for the sum of 1/4 and 1/2. To find the answer, we need to find a common denominator, which in this case is 4. When we convert 1/2 to have a denominator of 4, it becomes 2/4. Now, we can add 1/4 and 2/4, which gives us a total of 3/4. Therefore, the correct answer is 4-Mar.

13. If two lines are perpendicular, what could their slopes be?

1/9 And -1/9

1/9 And -9

1/9 And 9/1

-1/9 And -9

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.

Explanation

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.

14. What is the complement of a 41 degree acute angle?

131 Degrees

4 Degrees

41 Degrees

49 Degrees

The complement of an acute angle is the angle that, when added to the given angle, equals 90 degrees. Since the given angle is 41 degrees, the complement can be found by subtracting 41 from 90, which equals 49 degrees. Therefore, the correct answer is 49 degrees.

Explanation

The complement of an acute angle is the angle that, when added to the given angle, equals 90 degrees. Since the given angle is 41 degrees, the complement can be found by subtracting 41 from 90, which equals 49 degrees. Therefore, the correct answer is 49 degrees.

15. What is the median of 2, 4, 6, 8, 10, 12?

6 To 8

7

6

8

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.

Explanation

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.
