A. Divide number of people in the shop by total people walking by:
66/125 = 0.528 = 0.53
B. Divide people who bought something by total people walking by:
21/125 = 0.168 = 0.17
d. 66 -21 = 45 people don’t buy anything.
45/66 = 0.68
1, 3, 5, 7, 15, 21, 35, 105 these are the factors of 105.
The sum of the prime factors is 3+5+7=15
Not sure why they put the x bit
ok so know this:
AGE=HGB=CHG=FHD
and
AGH=EGB=CHF=GHD
and
AGE+AGH=180
11.
AGE=FHD=30
12.
AGH=CHF=150
13.
CHF=BGE=110
14.
CHG+HGA=180
CHG+120=180
CHG=60
15.
BHG=3x=AGE=CHG=FHD
not sure, but if we did use the fact that BGH+DHG=180 and BGH=3x and DHG=2x+50 then BHG=78 degrees
16.
GHD=2x+50=CHF=EGB=AGH, if we use facts above then GHD=102 degrees
Answer:
E; 8x9 is equal to 72 which estimated is 70
Assuming these are the angles for the inside of the triangle:
c=2
Step-by-step:
108+42+15c=180
150+15c=180
15c=30
c=2
