2 The Skoblickis are building a new home. The scale
yanalaym [24]

The actual width of the room is 20 ft and the actual length of the room is 15 ft

Since on the scale, 2 in : 5 ft and the width of the room on the drawing is 8 in.

Let the actual width of the room is w.

The ratio of the drawing to actual width is   8 in : w

So, 2 in : 5 ft = 8 in : w

2 in/5 ft = 8 in/w

So, w = 8 in × 5 ft/2 in

w = 4 × 5 ft

w = 20 ft

Also, the length of the room on the drawing on the drawing is 6 in.

Let the actual length of the room is L.

The ratio of the drawing to actual length is   6 in : L

So, 2 in : 5 ft = 6 in : L

2 in/5 ft = 6 in/L

So, L = 6 in × 5 ft/2 in

L = 3 × 5 ft

L = 15 ft

So, the actual width of the room is 20 ft and the actual length of the room is 15 ft.

The amount​ (in megawatts) of energy generated in a country from wind power can be modeled by the function ​W(t)equalsw0​(1.90​)
Ad libitum [116K]

Answer with Step-by-step explanation:

We are given that

W(t)=W_0(1.90)^t

Where t corresponds to the year 2000=0

a.W(0)=2540MW

Substitute the values

2540\times 10^6=W_0(1.90)^0=W_0

W_0=2540MW

b.In  2004

t=4

W(4)=2540(1.90)^4

W(4)=33101.534 MW

c.In 2013

t=13

W(13)=2540(1.9)^{13}=10.68\times 10^6MW
