(x/100-1)(x/100+1)=kx^2-1
(x/100-1)(x/100+1)=(x/100)^2 - 1^2 because it's a difference of squares ( (a-b)(a+b) = a^2-ab+ab-b^2 = a^2 - b^2):
(x/100)^2 - 1^2=kx^2 - 1
(x/100)^2 - 1=kx^2 - 1
(x/100)^2=kx^2
(x^2)/(100^2)=kx^2
1/(100^2)=k
1/10000=k
k=0.0001
Answer:
The width of the yard is approximately 6 feet.
Step-by-step explanation:
1 cubic yard = 27 cubic feet. Then we must find the number of cubic yards.
So we know for 1 cubic yard = $98
And for "x" cubic yard = $58.07
1/x =98/58.07
x = 0.5925
After we figure this out we need to convert this into cubic feet
1 cubic yard = 27 cubic feet
0.5925 cubic yard = x cubic feet
1/0.5925= 27/x
x = 15 .99 cubic feet
So,
width x height x length = 16 cubic feet
w x 8 x (1/3) = 16
w = 48/8 = 6 feet
So:
The answer is:
The width of the yard is approximately 6 feet.
