Asmall diagram in a textbook is 3 cm x 4 cm. the teacher takes the textbook to the copier to enlarge the diagram. if the teacher hits 150% in the copier, what are the new dimensions of the diagram after being copied?

4.5 cm x 6 cm

Step-by-step explanation:

Notice that the 150% enlargement can be written as a fraction:

That gives us a clue about what value to multiply each side of the textbook by  in order to obtain the new enlarged dimensions.

Therefore, the side which is 3 cm now becomes:

and the side which is 4 cm now becomes:

answer: t=3

step-by-step explanation:

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
