Elly poured 1/10 gallon of water into an empty bottle. now is 1/2 full. how many cups of water does a full bottle hold?

3.2 cups.

Step-by-step explanation:

There are 16 cups in one gallon.

16 ÷ 10 = 1.6

Are 1.6 cups in 1/10 of a gallon. If the bottle is half full, that means we need to double this number(basically adding the two haves) to get the whole.

1.6 x 2 = 3.2

There is your answer. Let me know if you need anymore help!

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
