Answer:
Length=11.18 ft
Width=2.236 ft
Step-by-step explanation:
Step 1
Express the dimensions of the rectangular flower Bed as shown;
length=x
width=1/5 of the length=1/5×x=(1/5)x
Step 2
Express the formula for calculating area;
A=L×W
where;
L=length of the flower bed
W=width of the flower bed
In our case;
A=25 ft²
L=x
W=1/5x
replacing;
(1/5x)×x=25
(1/5) x²=25
x²=25×5=125
√x²=√125 ft²
x=11.18 ft
Length=11.18 ft
Width=(1/5)×11.18=2.236 ft
Answer:
(A) $500,000
Step-by-step explanation:
Given formula for finding the cost ( in dollars ) to remove p percent of a certain pollutant,
If P = 90,
If P = 80,
∵ 900000 - 400000 = 500000,
Hence, it will cost $500,000 more to remove 90% of the pollutant from the pond than it would cost to remove 80% of the pollutant,
Option '(A)' is correct.
I wrote it down and it would be too difficult to type but i hope this helps
