Answer:

248

Step-by-step explanation:

A car rental company rented out 8 cars in its first month.

The number of cars it rented doubled each month.

The given situation forms G.P.

a = first term = 8

r = common ratio = 2

Formula of sum of first nth term in G.P. = S_n=\frac{a(1-r^n}{1-r}

Now we are supposed to find total number of cars the company rented out for the first 5 months.

Substitute n = 5

S_5=\frac{8(1-2^5)}{1-2}

S_5=248

Hence the total number of cars the company rented out for the first 5 months is 248.

kramer

Answer:

Figure 1:

Area: 30m^2

Perimeter: 23.6m

Area: 98.8km^2

Perimeter:56.5km

Perimeter: 6+5.8+6+5.8=23.6m

Figure 2:

Area:

7.6x13 = 98.8km^2

Perimeter:7.6+15+20+13.9=56.5km
