Answer:
It would take 10 days for 2 people working for 5 hours a day to fix a road.
Step-by-step explanation:
Given:
Let the number of people be denoted by 'p'.
Let the number of hours be denoted by 'h'.
Let the number of days be denoted by 'd'.
Solution:
Now given:
Case 1:
It take 10 people working 2 hours a day 5 days.
so we can say that;
![p_1=10](https://tex.z-dn.net/?f=p_1%3D10)
![h_2=2](https://tex.z-dn.net/?f=h_2%3D2)
![d_2=5](https://tex.z-dn.net/?f=d_2%3D5)
Now we can say that.
Job Completed can be calculated by multiplying number of people with number of hours and number of days.
So we can say that;
Job Completed = ![p_1\times h_1 \times d_1 =10\times 2\times 5 =100](https://tex.z-dn.net/?f=p_1%5Ctimes%20h_1%20%5Ctimes%20d_1%20%3D10%5Ctimes%202%5Ctimes%205%20%3D100)
Case 2:
We need to find the how many days will it take 2 people working 5 hours a day to fix a road.
So we can say that;
![p_2=2](https://tex.z-dn.net/?f=p_2%3D2)
![h_2=5](https://tex.z-dn.net/?f=h_2%3D5)
![d_2=?](https://tex.z-dn.net/?f=d_2%3D%3F)
Now we know that;
Job Completed = ![p_1\times h_1 \times d_2 =2\times 5\times d_2 =10d_2](https://tex.z-dn.net/?f=p_1%5Ctimes%20h_1%20%5Ctimes%20d_2%20%3D2%5Ctimes%205%5Ctimes%20d_2%20%3D10d_2)
Now we know that Job completed would be the same so we can say that;
![10d_2=100](https://tex.z-dn.net/?f=10d_2%3D100)
Dividing both side by 10 we get;
![\frac{10d_2}{10}=\frac{100}{10}\\\\d_2=10\ days](https://tex.z-dn.net/?f=%5Cfrac%7B10d_2%7D%7B10%7D%3D%5Cfrac%7B100%7D%7B10%7D%5C%5C%5C%5Cd_2%3D10%5C%20days)
Hence we can say that It would take 10 days for 2 people working for 5 hours a day to fix a road.
Answer:
185 cents
Step-by-step explanation:
11 inches -------------> cost 55 cents

<span>C) r= d/2
that's the answer</span>
In a 45 45 90 triangle, the length of each leg = hypotenuse / sq root (2)
each leg = (24 / 1.4142)
each leg = 16.971
Area of a triangle = (base * altitude) / 2
Area of a triangle = (16.971 * 16.971) / 2
Area = 144.007
Depende on situation but no not always the same as y and x
