Ala make 19 cookies in 30 min and Jane make 30 in 45 min so what is total cookies made by both in 1.5 he

See explanation

Step-by-step explanation:

The last part of your question isn't well written but let me rewrite based on what I think should be there.

Ala make 19 cookies in 30 min and Jane make 30 in 45 min so what is total cookies made by both in 1.5 hour?

Since Ala makes 19 cookies in 30 minutes. The number of cookies made in 1.5 hours will be:

= 19 × 1.5hours/30 minutes

= 19 × 90min/30min

= 19 × 3

= 57 cookies

Jane make 30 in 45 min. The number of cookies made in 1.5 hours will be:

= 30 × 1.5hours/45minutes

= 30 × 90minutes/45minutes

= 30 × 2

= 60 cookies

The total cookies made by both will then be:

= 57 + 60

= 117 cookies

Note that 1.5 hours = 1.5 × 60 minutes = 90 minutes

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
