Answer:
i will only answer 11 and 4
Step-by-step explanation:
4: 23 i know its not the whole thing
11:45 its not the full thing
First, we convert it into a unit like this
20 workers × 30 days = 600 units work
After leaving the 5 workers, we have 35 days to complete the work.
In 35 days only 15 workers will do the work.
So the work completed in 35 days by 15 workers = 35 ×15 =525 units
Remaining unit = 600 -525 =75 units
This unit would do by 5 workers in (75/5) = 15 days.
So after 15 days, 5 workers should leave the job.

Answer:
2.5 cm
Step-by-step explanation:
Rectangle A L x W = 40
Rectangle B L * W = 1/2 (40)
8 * W = 20
W = 2.5 cm
I would think the value would be .2 cause if you had 100 tosses you would expect 60 value for heads and -40 value for tails. giving you 20/100
