Change in the amount of water in the bathtub after -48.75 gallons. Negative sign means water get reduce by 48.75 gallons in bathtub.
<h3><u>Solution:</u></h3>
Given that
A clogged bathtub drains at a constant rate.
The amount of water in the bathtub changes by –3.75 gallons in one hour.
Need to determine change in the amount of water in the bathtub after 13 hour.
Change in amount of water in bathtub in one hour = -3.75 gallons
As given that clogged bathtub drains at a constant rate, so
Change in amount of water in bathtub in 13 hours = 13 x Change in amount of water in bathtub in 1 hours
=> Change in amount of water in bathtub in 13 hours = 13 x ( -3.75 ) = -48.75 gallons
Hence change in the amount of water in the bathtub after -48.75 gallons. Negative sign means water get reduce by 48.75 gallons in bathtub.
Answer: the Russell family used their sprinkler for 40 hours.
the Gonzalez family used their sprinkler for 20 hours.
Step-by-step explanation:
Let x represent the number of hours for which the Russell family used their sprinkler.
Let y represent the number of hours for which the Gonzalez family used their sprinkler.
The families used their sprinklers for a combined total of 60 hours. It means that
x + y = 60
The water output rate for the Russell family's sprinkler was 35L per hour. The water output rate for the Gonzalez family's sprinkler was 40L per hour. The total water output of both families was 2200L. It means that
35x + 40y = 2200- - - - - - - - - - --1
Substituting x = 60 - y into equation 1, it becomes.
35(60 - y) + 40y = 2200
2100 - 35y + 40y = 2200
- 35y + 40y = 2200 - 2100
5y = 100
y = 100/5
y = 20
x = 60 - y = 60 - 20
x = 40
