Answer:
It will take 3.6 hours to wax a car if they work together.
Step-by-step explanation:
Calvin one hour work = 
Alvin one hour work = 
To find out how much they can do together per hour,
We have to add
and 
= 
=
--------------(1)
They can do
of the job per hour.
If "t" is the time taken to finish the job together, then one hour work
------------------------(2)
Now we have to find the value of "t" by setting the expression (1) and (2) equal.

It can solve by flipping the equation;

t = 3.6 hours
It will take 3.6 hours to wax a car if they work together.
Step-by-step explanation:
the second answer.
they are parallel and congruent (same length).
simply because both points were translated by adding the same number of units to x. so, they have the same length, and point in the same direction.
Answer:
I think the answer is 3/8 bight i might be wrong.
Step-by-step explanation:
3/4*1/2=3/8
All I did was multiply the two fractions.
The answer is, 402m.
Explanation)
A = pi(r)^2
A = pi(8.5)^2
A = 113
//
A = x^2
A = 17^2
A = 289
Now add these two values (289 & 113) together and you'd get 402.
Hopefully, I helped you out!
