If $1=Rs. 102.50 and £ 1=Rs, 140, how many dollars equals to £5?

$6.83= £5

Step-by-step explanation:

As £ 1=Rs 140

So, £5 = Rs 140 x 5

£5 = Rs 700 ...(i)

Now, Rs. 102.50 = $ 1

So, Rs. 1 = $ (1/102.5)

Therefore, Rs. 700 = $ (1/102.5)x 700 = $6.83

By using equation (i)

£5 = $6.83

Hence, there are $6.83= £5

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.
