Afilter has been designed to have a run length of 48 hr while operating at a filtration rate of 12 m/h. the design backwash rate is 40 m/h, backwash duration is 15 min, and filter-to-waste duration is 10 min. the plant operators decided to clean the filters more thoroughly and they backwash at a rate of 55 m/h for 25 min. as a result, ripening takes longer and the filter-to-waste duration is 50 min. calculate the ufrv, ubwv, ufwv, and recovery (a) as designed and (b) as operated. what is the percent increase in the volume of treated water lost as waste backwash water and filter-to-waste water?

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
