Let's assume length of the room as y
so the width of the room = y - 5
Area
y * (y - 5) = 750
Answer:
y = 5
Step-by-step explanation:
This is a multi-step equation, so you can solve for the variable 'y' by using a series of steps:
1. Combine like terms:
-4y - 3 = 5 - 3y + 6 -19 or -4y - 3 = -3y - 8
2. Isolate the variable using inverse (opposite operations):
Add 8 to both sides: -4y - 3 + 8 = -3y - 8 + 8 or -4y + 5 = -3y
Add -4y to both sides: -4y + 5 + 4y = -3y + 4y
3. Solve for 'y'
5 = y
There is no graph to determine
So first, let us say that the inner circle is circle B and the outer circle is circle A. The area of circle A minus the area of circle B gives you the area between them. So, the area of circle A is 14²π = 196π. The circle B's area is 6²π = 36π. Hence, the area is 160π between both of them. Now, the area of the outer circle as we found is 196π, so the probability that I would choose a point between the outer and inner circle is 160π/196π = 40/49.
