Two beauticians, lydia and jackie, are working on your hair. lydia can complete the work in 2 hours, while jackie can complete the work in 1 hour. how many hours do the beauticians take if they work together?

a. one half
b. three halvess
c. two thirds
d. four thirds

Option C.

Step-by-step explanation:

Two beauticians Lydia and Jackie are working on your hair.

Lydia takes the time to complete the work = 2 hours

Per hour work done by Lydia = 1/2

Jackie complete the  work = 1 hour

In one hour total work done by both Jackie and Lydia together =

therefore, time taken by both to complete the work will be = =

Option C. two thirds is the correct option.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
