Identify the mapping abc to edc
-reflection
- rotation
-glide reflection
-translation

 Second option is correct.

Step-by-step explanation:

Since we have given that

Δ ABC is mapping to Δ EDC.

According to figure:

Point of rotation is 'C' as C point wont change after rotation.

When there is a rotation 180° clockwise through the point of rotation 'C'.

When we rotate 180° clockwise :

A goes to E and B goes to B.

So, Δ ABC ⇒ Δ EDC

Hence, Second option is correct.

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
