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:
20 I think I hope it is correct
Answer:
48.4 hours
Step-by-step explanation:
Time = Distance/Rate
Answer:
6 and -6
Absolute value mans the distance a number is away from 0.
Answer: ( 2, -6 )
Step-by-step explanation:
rewrite y= (x-6)(x+2) in the form y=ax^2+bx+c
Y=(x-6)(x+2)
(x-6)(x+2): x^2-4x-12
y=x^2-4x-12
the parabola params are :
a=1, b= -4, c=-12
x^v=-(-4)/ 2*1
x^v=2
y^v=-16
