8) If 15 balls cost Rs 225 then the cost of 8 balls is​

The cost of 8 balls is Rs $ 120.

Step-by-step explanation:

Given that 15 balls cost Rs $ 225, to determine the cost of 8 balls it is necessary to perform the following mathematical calculation:

(225/15) x 8 = X

15 x 8 = X

120 = X

Thus, the cost of 8 balls is Rs $ 120.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
