Jimmy can oil the lanes in a bowling alley in eight hours. perry can oil the same lanes in nine hours. how long would it take them if they worked together?

It would take or 4.24 hours 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.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
