Answer:

180 ft

Step-by-step explanation:

We are working to find the perimeter here. Let x represent the length of the room.

We know that the formula to find the perimeter of something is 2L + 2W = P. Here, we know the required perimeter and the width of the room.

Our equation is now: 2x + 2(70) = 500

Now we have to find x, we'll start by multiplying 70 by 2.

2x + 140 = 500

Now we can solve for x:

Subtract 140 from both sides

2x = 360

x = 180

The length of this room is 180 ft.

2(180) + 140 = 500

360 + 140 = 500

Enter the finite geometric series from its given description, and then enter its sum.
Mama L [17]

Answer:

a_n= 4(-5)^{(n-1)}

-10416

Step-by-step explanation:

a = 4

r = -5

geometric series:  a_n=ar^{(n-1)} = 4(-5)^{(n-1)}

Determine which term = -12500:

a_n=-12500

4(-5)^{(n-1)}=-12500

(-5)^{(n-1)} = -3125

(5)^{(n-1)} = 3125

(n-1)ln(5) = ln(3125)

n-1 = ln(3125)/ln(5) = 5

n = 5 + 1 = 6

a_6=-12500

Using geometric sum series formula: S_n=\frac{a(1-r^n)}{1-r}

Therefore, S_6=\frac{4(1-(-5)^6)}{1-(-5)} =\frac{-62496}{6} =-10416
