Arc length = rθ [r = radius of the circle, θ = central angle in radians] ⇒
2π = 8*θ ⇒ θ = 2π/8 = π/4
Multiply 14 times 91 then divide by 14 times 5.
1274/70= $18.20
I assume you want to mathematically represent the above
Answer and explanation:
If Diego collected x kg of recycling and Lin collected 2/5 more than what Diego collected, then it would be represented mathematically thus:
Diego = x
Lin = x +2/5 of x= x+2/5x
if Lin biked x km and Diego biked 3/10km less than Lin, then we would represent this thus:
Lin=x
Diego= x-3/10 of x= x-3/10x
If Diego reads for x minutes and Lin reads 4/7 of what Diego read, then mathematically we represent this thus:
Diego=x
Lin =4/7 of x = 4/7x
