Iran 8kilometers in 20 minutes that cost me $10 how many miles would it be if cost is $30

14.91288  miles

Step-by-step explanation:

We can use a proportion to solve this problem.  Put the distance over the cost.  We want our answer in miles so we need to convert 8 kilometers to miles.   1 km = .621371 miles

8 km * .621371 miles/ 1 km = 4.971 miles

4 .971 miles          x miles

=

10 dollars               30 dollars

Using cross products

4.971 * 30 = 10x

149.1288= 10 x

Divide by 10 on each side

149.1288/10= 10/10 x

14.91288 =x

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
