On a scale drawing of a submarine, each 0.5 cm represents 3 m on the actual submarine. what length on the submarine is represented by 3 cm on the drawing?

The length of the actual submarine is 18 m.

Step-by-step explanation:

Here, the conversion ratio is

0.5 cm represents 3 m on actual submarine.

also, 3 m  = 3 x 100 cm  = 300 cm

or, the ratio of Drawing : Actual   =  0.5 : 300

Now, Here drawing = 3 cm

let the actual length of the submarine = k cm

By the RATIO of PROPORTIONALITY:

or, k = 1800 cm  = 18 m

Hence, the length of the actual submarine is 18 m.

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
