Suppose that 13 inches of wire cost 39 cent how much would 8 inches cost

24 cent

Step-by-step explanation:

If 13 inches of wire cost 39 cent.

We have to calculate how much 1 inch of wire would cost first, before determining the cost of 8 inches of wire.

If 13 inches of wire costs 39cents, Then 1 inch of wire would cost 3 cent.

That is 39/13, which gives 3.

If 1 inch of wire cost 3 cents. Two inches of wire would cost 6 cents we 3 inches of wire costs 9 cents.

To get the cost of 8 inches of wire, we therefore multiply 8 by 3, which gives 24.

8 inches of wire costs 24 cents.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
