*WILL MARK BRAINLIEST* simplify the irrational number square root of 45, then estimate it to two decimal places.

3 which is approx 6.71

Step-by-step explanation:

= · = 3

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

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
