14. A
17. B
18. D
Im not sure about the others though.
#1) Arrange the numbers from least to greatest.
#2) If there is a odd amount of numbers the middle number is your answer.
but if there is a even amount of numbers, take those two middle numbers, add them, then divide them by two. Then you got your answer.
its sqrt(5) since sqrt(5) isn't a whole number(its like 2.23)
Answer:
67.5 degrees
Step-by-step explanation:
The angle between the 6 and the 9 = 90 degrees.
WE can say that the hour hand is ' 3/4 of 5 minutes' past the 6.
5 minutes is equivalent to 360 / 12 = 30 degrees.
Thus the angle between the 6 and the hour hand
= 30 * 3/4
= 22.5 degrees.
The required angle is 90 - 22.5
= 67.5 degrees.
Answer:
c
Step-by-step explanation:


add -x to both sides

multiply both sides by -1/2


the equations don't have the same slope so they aren't parallel
The solpes product doesn't equal -1 so they aren't perpendicular
