Step-by-step explanation:
Answer:
40
Step-by-step explanation:
Ratio of cars to total:
32:80
so we can make another ratio with x
x:100
now make them fractions and cross-multiply
32/80 = x/100
32(100) = 80x
80x = 3200
x = 40
The sum of the angles of 4-sided shapes is 360°
To find the missing angle, you can do this:
x + 92° + 47° + 82° = 360° Add 92, 47, and 82 together
x + 221° = 360° Subtract 221 on both sides to get "x" by itself
x + 221° - 221° = 360° - 221°
x = 139° Your answer is the 4th option
I'm pretty sure it is 72.42237223 ( that's before rounding)
3:4 = 3/4
3/4 = 3 divided by 4
3 divided by 4 = 0.75
0.75 = 75%
C. 75%
