Answer: the sprinkling rate of the butler family's sprinkler is 40L per hour
the sprinkling rate of the Clark family's sprinkler is 20L per hour
Step-by-step explanation:
Let x represent the sprinkling rate of the butler family's sprinkler.
Let y represent the sprinkling rate of the Clark family's sprinkler.
The butler family's sprinklers was used for 40 hours. The Clark family's sprinkler was used for 30 hours. There was a combined total output of 2200L of water. This means that
40x + 30y = 2200 - - - - - - - - - - -1
if the sum of the two rates was 60l per hour, it means that
x + y = 60
Substituting x = 60 - y into equation 1, it becomes
40(60 - y) + 30y = 2200
2400 - 40y + 30y = 2200
- 40y + 30y = 2200 - 2400
- 10y = - 200
y = - 200/ - 10
y = 20
Substituting y = 20 into x = 60 - y, it becomes
x = 60 - 20 = 40
The linear function from the table is given by y = 16x.
<h3>
Linear function</h3>
A linear function is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope of the line) and b is the y intercept.
Let y represent the number of tickets sold within x hours.
From the table, using the point (2, 64) and (18, 576):
The linear function from the table is given by y = 16x.

The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle.
If a circle has a diameter of 4, its circumference is 3.14*4=12.56.
If you know the radius, the diameter is twice as large.
Answer:
x = 18
Step-by-step explanation:
The smaller triangle (the one with sides 80 and 60) is similar to the larger one (meaning that the ratio of the sides should be the same).
The ratio is 4:3:
27 + 60 = 87
87/3 = 29
29*4 = 116
2x + 80 = 116
2x = 36
x = 18
