I really need help with number 12

Usimov [2.4K]

Answer:

7.8125 gallons

Step-by-step explanation:

Because 5 gallons would cover 1600 square-foot wall so 1 gallon would cover:

1600 / 5 = 320 square-foot wall.

Which relationship has a domain of real numbers?

babunello [35]

Answer:Domain: all x-values that are to be used (independent values).

Step-by-step explanation:The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range. Domain: all x-values that are to be used (independent values).
