Darts are thrown at a circular board. If a dart hits the board, what is the probability that it will land on the center circle. **10 is from the center to the edge.
A)1/25
B)1/4
C)1/5
D)3/5

1/25

Step-by-step explanation:

Calculate the area of the centre circle (pi*2^2) and then calculate the area of the whole circle (pi*10^2) and then divide pi*4 by pi*100 which gives you 4/100=1/25

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
