A 5 kW solor energy system can collect 9000 kWh of energy per year. In Arizona, electricity cost eleven cents per kilowatt hour.
Licemer1 [7]

Answer:

19338 kWh

Step-by-step explanation:

In Arizona, electricity cost eleven cents per kilowatt-hour.

The average home uses 66 million BTU per year i.e. 66000000 BTU per year.

Now, it is given in the question that 1 BTU is equivalent to 0.000293 kWh.

So, the average home uses (66000000 × 0.000293) = 19338 kWh per year.

Therefore, the number of kilowatt-hours used per year will be 19338. (Answer)

A trapezoid is broken into 2 triangles and 1 rectangle. The triangles both have a base of 2 meters and a height of 5 meters. The
Lemur [1.5K]

Answer:

Part 1) The trapezoid has an area of  20\ m^2

Part 2) The kite has an area of  21\ m^2    

Part 3) The area of the trapezoid is less than the area of the kite

Step-by-step explanation:

Part 1

Find the area of trapezoid

we know that

The area of trapezoid is equal to the area of two congruent triangles plus the area of a rectangle

so

A=2[\frac{1}{2} (2)(5)]+(2)(5)

A=10+10=20\ m^2    

Part 2

Find the area of the kite

we know that

The area of the kite is equal to the area of two congruent triangles

so

A=2[\frac{1}{2} (7)(3)]=21\ m^2

Part 3

Compare the areas

The trapezoid has an area of  20\ m^2

The kite has an area of  21\ m^2  

so

20\ m^2< 21\ m^2

therefore

The area of the trapezoid is less than the area of the kite
