3 × ( p + 4m ) + 8 and 3p + 4 × ( 3m + 2 ) are the equivalent expressions.
Triangle FOD is an isosceles with base FD.
FD = 2 · 4 = 8
FD = CB
Arc CB = 56°
Arc ED = 1/2 Arc FD = 1/2 Arc CB
Arc ED = 56° : 2
Answer:
Arc ED = 28°
Answer:
1750 tickets
Step-by-step explanation:
100 x 14 is 1400, so 125 x 14 will be the answer. 125 x 14 = 1,750. The answer is 1,750 tickets.
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.
