Hey there!
Answer:
CD = 3.
Step-by-step explanation:
Since the triangles are similar, we can set up a ratio to determine the other side-lengths:

Cross multiply:

Distribute the '6':

Combine like terms and simplify:


Therefore, the length of CD is 3.
Answer:
3.3 gallons
Step-by-step explanation:
(2 3/4)/x = (3 1/3)/4
(11/4)/x = (10/3)/4 (cross multiplication)
(11/4)*(4/1)=44/4=11
11/(10/3) = ( 11/1 ) * (3/10) = 33/10 = 3.3 gallons
