7out of 20 students got full marks on their test what angle would you use for this on a pie chart

7/20 times 360  (360 is the full degrees in a pie chart)

there are 18 20's in 360.  

7 times 18 is 126

or

2520/20  = 126

So, you'd use a 126 degree angle.    

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
