ANSWER

\boxed { r = \frac{Q}{8 {s}^{2} } }

EXPLANATION

The given equation is;

Q=8rs^2

We want to solve this equation for r.



This means that we need to isolate r, so that it will be on one side of the equation, while all other variables and constants are also on the other side.


Let us divide both sides of the equation by

8 {s}^{2}

to obtain,


\frac{Q}{8 {s}^{2} } = \frac{8rs^2}{8 {s}^{2} }



We cancel out the common factors to obtain,



\frac{Q}{8 {s}^{2} } =r
Or

r = \frac{Q}{8 {s}^{2} }

A grid is 10 squares high and 10 squares wide. The distance between each grid square is 3 feet. The triangular viewing area of c
meriva

Answer:

1) 8

2) 450 ft^2

Step-by-step explanation:

Each triangle takes half a square worth of space, so if you add up 2 triangles for 1 square that is 1/4 of the area, multiply that by 4 and you get 8 cameras.

The left over space in the store is the same amount of space as all the cameras space added together since each camera takes up half a square. That way 4 cameras(each 112.5 ft^2 each) equals 1/2 of the room which added together is 450 ft^2, the other half would be the left over space, 450 ft^2.
