The area of the blue outer ring is given by the area of the entire circular archery less the area of the inner pink circle.

The area of a circle is given by

Area=\pi r^2, where r= \frac{d}{2}, r is the radius, d is the diameter.

Therefore, the area of the outer blue ring is given by:

Area=\pi\left( \frac{24}{2} \right)^2-\pi\left( \frac{6}{2} \right)^2 \\  \\ =\pi(12^2-3^2)=\pi(144-9) \\  \\ =135\pi\ in^2

6(x-5) = 5(x+5)
Mariana [72]

Part 1:

6(x-5) = 5(x+5) (x = 55)

4y + 2 (-3 + 2y) = 1-y (x = 7/9)

Part 2:

4(a-6) = 8a - (4a-24) (No Solution)

4(2x-8) = 8(x-8) (No Solution)

2(3x-3) = -6x-6 (Identity (x = 0))

Tigers:-

f(t)  = 7(1 + 0.1)^2   where t = number of years

Eagle 

g(t)  =  15 + 2t

  number of eagles = 15 + 10(2) = 35

C when the number of tigers = number eagles the 2 functions will be equal;-

f(t) = g(t)  that is:-

7* 1.1^t  = 15 + 2t

solve for t
