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.
1/4th of Mai’s height is equal to 2/5th of Jon’s height
Let 'x' represent Mai's height and 'y' represent Jon's height.
Therefore, 1/4th of "x" should be equal to 2/5th of "y". This gives us the following equation :
(1/4)x = (2/5)y
multiply both sides by 4/y
x/y = 4*(2/5)
x/y = 8/5
x:y = 8:5
The ratio of Mai's s height to Jon's height is 8 to 5
