Answer:
9.44 inches
Step-by-step explanation:
In order to find the average rainfall, setting up a proportion, or equivalent ratios, would be the easiest way to find the measurement. Given that 23.6 inches represents 250% of the average:
, where 'x' represents the average rainfall
cross-multiply: 250x = (23.6)(100) or 250x = 2360
divide: 250x/250 = 2360/250
x = 9.44 inches
The answer is 40 percent .
There's a total of 25 students .
10 of them are boys
10/25 = .4
.4=40%
Answer:
Step-by-step explanation:
1: The first equivalent fraction for 3 / 21 is 1/7.
2: The second equavalent fraction is 2/14.
8x+15 = 2x+39
8x =2x+24
6x = 24
x = 24/6 = 4
angle 4 = 2(4) +39 = 8+39 = 47
angle 6 = angle 4
angle 6 = 47 degrees
1-5/8=3/8
If he had 5/8 leftover, then he used 3/8.
