I=prt
20=p X .05 X 5
20 = p X .25
20/.25 = p
80 = p

Answer:
sum of an exterior angle is 360
2x+56+85+57+4x=360
6x+198=360
6x=360-198
6x=162
x=162/6
x=27
Answer:
6,000:3
Step-by-step explanation:
Answer:
Part A: Data summary is given in the table
Part B: out of the total 100 students, 15 students do not like either tennis or track
= 0.15
0.15 × = 15%
Part C:
Total no. of students that dislike track = 60
Total no. of students that dislike tennis = 40
According to the survey results, more people dislike track.
the horizontal tangent line mean y'=0
8 - 2x = 0
x = 4
