Darla can do a job in eight hours while Lonnie can do the same job in six hours. Both Darla and Lonnie work three hours on the job. How much of the job is left to be finished

Look below ⏬

Step-by-step explanation:

Darla 8h

Lonnie 6h

They both worked 3 hours now

subtract

8-3=5

6-3=3

Darla have 5 hours to finish

and...

Lonnie has 3 hours to finish

all together is 8 hours in all

Step-by-step explanation:

Time/work completed so far

Darla 3/8

Lonnie 3/6 = 1/2

Add together to get completed work so far to determine what's left.

1/2 = 4/8 to create common denominators

3/8 + 4/8 = 7/8 completed so therefore has 1/8 of the job remaining between the two of them.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
