(4/9)² ÷ ( 1/3 + 2/9 – ½) this is an order of operation with exponet problem
please show work and explain how you got the answer

When using the order of operations to solve the problem, then the final answer will be

Step-by-step explanation:

÷

Following the order of operations, the first thing we have to do is add 1/3 to 2/9 and then subtract that sum by 1/2.

÷

÷

Next, we solve the exponent on 4/9 by multiplying 4/9 with itself.

÷

Lastly, we divide 16/81 by 1/18.

÷ =

Since this number can not be simplified into a smaller fraction, then the answer will stay as it is.

So, your final answer will be

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
