Greeley [361]

Answer:

  13.25 ft

Step-by-step explanation:

Let w represent the width of the window. Then w-5 represents the length, and the perimeter is ...

  P = 2(L+W)

  43 = 2((w-5) +w) = 4w -10

  53/4 = w = 13.25 . . . feet

The width of the window is 13.25 ft.

I need help with math the question is
velikii [3]

Answer:

P=2(S-lw)/h

Step-by-step explanation:

we have that

The formula for the surface area of the enclosed space is

S=lw+0.5Ph

Solve for P

That means ------> isolate the variable P

Subtract lw both sides

S-lw=lw+0.5Ph-lw

S-lw=0.5Ph

Multiply by 2 both sides

2(S-lw)=(2)0.5Ph

2(S-lw)=Ph

Divide by h both sides

2(S-lw)/h=Ph/h

2(S-lw)/h=P

Rewrite

P=2(S-lw)/h

option 1.2: customer 1 withdraws 2 $20 bills AND customer 2 withdraws 4 $10 bills

Case 2: customer 1 withdraws 4 $10 bills

option 2.1:  customer 1 withdraws 4 $10 bills AND customer 2 withdraws 2 $20 bills

option 2.2: customer 1 withdraws 4 $10 bills AND customer 2 withdraws 4 $10 bills

options 1.1, 1.2, 2.1 and 2.2 give us a total of four ways for the customers to retrieve thier money.
