Answer:
15.75 ft²
Step-by-step explanation:
6" is 0.5 ft, so the dimensions in feet are 4.5 ft by 3.5 ft. The area is the product of these dimensions:
A = (4.5 ft)(3.5 ft) = 15.75 ft²
Answer:
Intensity

In physics, intensity of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy.
I'm not sure but I think it is the first one
There is 100% in 1 since this is three parts of 1 we will have to divide 100 by 4 then multiply it by 3.
After you do all the math you will get 0.75.
You can convert this to a percent by just removing the point and the zero and adding a percent at the end.
The answer is going to be 75%
The answer is A, developed nations make up about 20 percent of population yet consume 75 percent of sources.
