Answer:
Step-by-step explanation:
Let r represent the radius of the circle (in cm) and
let C represent the circumference of the circle (in cm).
First solve the equation for 'r' using circumference formula
Circumference of circle formula is
Solve for r, divide both sides by 2pi
the function g determines the radius of the circle in cm
So we replace 'r' with g(C), where C is the circumference
For this case, the first thing we are going to do is define variables.
We have then:
x: number of hours it takes Homer to finish work alone.
They worked together for 3 hours until Homer had to go home:
Mike finished the job working by himself in an additional 5 hours:
From here, we must clear the value of x.
We then have to multiply both sides by x (x-1):
Rewriting we have:
The solutions to the equation are:
Answer:
it has taken Homer to fix the deck himself about:
x2 = 11.75 hours
