Answer:

The answer to your question is 23.42 ft

Step-by-step explanation:

Data

base = 6 ft

height = 4 ft

Process

1.- Calculate the length of the rectangle. Only consider the base and the left and right sides.

Length = 6 + 4 + 4

Length = 14 ft

2.- Calculate the Perimeter of the semicircle

Formula

Perimeter = 2πr/2 = πr

-Calculate the radius

radius = 6/2 = 3 ft

-Find the perimeter

Perimeter = 2(3.14)(3)/2

-Result

Perimeter = 9.42 ft

3.- Calculate the perimeter of the window

Perimeter = 14 + 9.42

                 = 23.42 ft

Zina [86]

Answer: 6,987,000 pounds fo CO₂ per kWh.

Step-by-step explanation: <u>Quilowatt</u>-<u>hour</u> <u>(kWh)</u> is a unit of energy that measures the amount of energy expended in 1 hour.

The AC uses 850 Watts, which in kW is 850,000 kW

If you leave the AC on for 6 hours, it will consume

850,000(6) = 5,100,000 kWh

Eletricity produces 1.37 pounds of CO₂ per kWh, then in 5,100,000 kWh:

1.37 \frac{pounds}{kWh}.(5,100,000kWh) = 6,987,000 pounds

If you open a window for 6 hours, you would keep 6,987,000 pounds of CO₂ for entering the atmosphere.
