Answer:
It would take
or <u>4.24 hours</u> to oil the lanes if they work together.
Step-by-step explanation:
Given:
Time to oil the lanes by Jimmy alone = 8 hours
Time to oil the lanes by Perry alone = 9 hours
Now, let the time taken by both working together be 'x' hours.
Part of the work done in 1 hour by Jimmy alone = 
Part of the work done in 1 hour by Perry alone = 
Part of the work done in 1 hour by Jimmy+Perry together = 
Now, total work in 1 hour is given as:

Therefore, it would take
or 4.24 hours to oil the lanes if they work together.
Answer:
B. (−17, 4)
Step-by-step explanation:
We can write the equation of a circle in the form
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x + 17)^2 + (y − 4)^2 = 23
(x - -17)^2 + (y − 4)^2 = ( sqrt (23))^2
The center is (-17,4) and the radius is (sqrt(23)
Answer:
37.5
Step-by-step explanation:
so 24 miles per hour
15 miles
15/24
= 0.625 hours
60 x 0.625 = 37.5
It took 37 and 1/2 minutes
