length of the rectangular field equals 87
Answer:
x = -9
Step-by-step explanation:
let the number = x
So x ÷ -3 = x + 12
Mulitply both sides by -3: x = -3x -36
Add 3x to both sides: 4x = -36
Divide both sides by 4: x = -9
68 miles to 42.5's percent of decrease is: 37.5%
Using proportions. 68 miles - 42.5 = 25.5
25.5 x
------ = -----
68 100
Cross multiply:
25.5 x 100 = 2550
68 multiply x = 68x
2550 divided by 68 = 37.5
x = 37.5%
Answer:
Step-by-step explanation:
If this was an entire circle, the area could be found by using
Area = pi * r^2 where r = 9
To take the central angle into account, use this formula
Area = 120/360 * pi * r^2
Area = 1/3 * pi * 9^2
Area = 27 pi
area = 84.78 cm^2 which isn't there.
