Samantha is trying to complete the free throw wellness challenge. in order to earn her chip, she needs to hit 13 out of 20 free throws on the basketball court her last three attempts were 12 out of 20, 10 out of 20, and 9 out of 20 how far is her average free throw percentage from the needed free throw percentage to earn the chip? (round to the nearest whole number)

21 % below what she needs

Step-by-step explanation:

She had hit 12, 10 and 9

This averages to

(12+10+9)/3 = 31/3 =10 1/3

She needs 13

Percentage = (needed-actual)/needed * 100%

                    = (13-10 1/3) / 13 * 100%

                    = (2 2/3) /13 * 100%

                    =.205128205 * 100%

                   =20.5128205%

To the nearest whole number

                      21 %

She is 21 % below what she needs

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
