It took 3 days to complete a work by 10 people.
<h3>What is Efficiency?</h3>
The efficiency is the output of the work which we divide by the work input and then express it in a percentage form.
Here, Efficiency of 1 person to complete a piece of work in 30 days is 1/30.
The number of days to complete the work = n days
Number of person to complete the work = p.
Now, according to question
Number of days to complete the work by 10 people = 30 / 10
= 3 days.
Thus, it took 3 days to complete a work by 10 people.

Answer:
30.25 pi
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
11 pi = 2 * pi *r
divide each side by 2 pi
11/2 = 2 ( pi) * r/ ( 2pi)
11/2 = r
We can find the area by
A = pi * r^2
= pi ( 11/2) ^2
= pi ( 121/4)
= pi ( 121/4)
= 30.25 pi
First, divide -5 on both sides:
(x + 7) < -2
Then subtract 7 on both sides:
x < -9
x < -9 is your final answer.
Answer: 4.2
Step-by-step explanation:
when you square root 18 you get 4.242. When rounded to the nearest tenth you get 4.2 since 4 is not nor is 5 and exceeds it.
