If a crew of 4 workers complete the job in 10 hours, how long will it take 5 workers to complete the same job? plz show your work.

It will take 8 hours for the 5 workers to complete the same job.

Step-by-step explanation:

The amount of work done is the same for both crews.

Work = time * workers

Work = 10 * 4      

Work = time * 5

Set the two equal

10 * 4 = time * 5

Divide each side of the equation by 5

10*4/5 = time *5/5

8 = time

step-by-step explanation:

see if this :

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
