Answer:
Step-by-step explanation:
- The job can be completed by 7 people in 11 days
- The job is equivalent of 7*11 = 77 people*days
<u>After 3 days, job left:</u>
- (11 - 3)*7 = 56 people*days
This was completed by 7 - x people as x people left
<u>Time needed was 14 days, we have new equation:</u>
- 14(7 - x) = 56
- 7 - x = 4
- x = 7 - 4
- x = 3
As we found, 3 people left

Answer: 67</h2>
Step-by-step explanation: 6.7 x 10^1 = 67
It should be x < -10 because when you divide by a negative number the inequality sign flips.
Answer:
144 sq. ft.
Step-by-step explanation:
In order to find the area, we have to know the length of the sides.
Since the figure is a cube, the way that the volume was found was by multiplying one side length by itself two times.
s^3 = cube volume.
So, to find the length of one side, we have to find the cube root of the volume.
= 12
Now that we know the side length, we just need to multiply it by itself to find the area of the floor space.
12 * 12 = 144
Your LCM is 11880 , and your HCF is 36
