Water/Wastewater Treatment:
A wastewater treatment operator uses the formula:
A = 8.34 FC
to determine the amount of Chlorine (A) to add to a basin. The flow through the basin is Fand the concentration of Chlorine to water is C
If F=1,800 and C=7,500,000 what is A?
(Round your answer to the nearest tenth.)

Solution:

Given that,

A wastewater treatment operator uses the formula:

Where,

A = amount of chlorine to add to basin

The flow through the basin is Fand the concentration of Chlorine to water is C

From given,

F = 1800

C = 7, 500, 000

To find: A

Thus amount of Chlorine (A) to add to a basin is 112590000000

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

the answer is 99.
