Answer:
The money he makes mowing lawn can be represented by a linear function.
The function can be represented in the slope-intercept form.
the equation of the function is y=500+10x
where
y=amount of money he has earned by mowing lawns.
x=number of lawn mowing clients he has.
Step-by-step explanation:
It can be represented by a linear function (straight line) because the <em>additional</em> amounts are proportional to the number of clients he has.
The equation is
y=500+10x
where
y=amount of money he has
x=number of lawn mowing client he has.
ANSWER
C. 35 men
EXPLANATION
Let m represent the number of men needed and d represent the number of days.
From the question,the number of men needed varies inversely to the time needed to complete the project.
We can write the inverse variation equation.

where k is the constant of variation.
When m=28, d =90.
We substitute these values into the variation equation to determine the value of k.



Now the equation becomes:

When d=72,


Therefore he needs to have 35 men working.
Answer:

Then the answer is C
Step-by-step explanation:
1) Set a linear equation

2) Cross multiply

3) Multiple the right side

4) Divide both side by 2

5) Solving the linear equation

The answer is (C)
Answer:
5 minutes.
Step-by-step explanation:
We have been given that a bank finds that the average number of people waiting in line during lunch hour is 10. On average, during this period, 2 people per minute leave the bank after receiving service.
We will use flow time formula to solve our given problem.


Therefore, on average bank customers wait in line for 5 minutes.
