HELP I HAVE TO FINISH IN 2 HOURS shannon and sarah are mowing a field. shannon can finish mowing by herself in 2 hours. sarah can finish in 4 hours. how long will it take them to mow the field together?

1h 20m

Step-by-step explanation:

Let the total amount of work be x.

Shannon:

2h = x

1h = x

So basically Shannon does  x work per hour.

Sarah:

4h = x

1h = x

So basically Sarah does x work per hour.

Together:

1h = x + x

    = x + x

    = x

Amount of time spent = x ÷ x

                                     = x × x

                                     = h

                                     = 1h

                                     = 1h 20m

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
