Answer:
Option C is correct
76 feet
Step-by-step explanation:
Area of square(A) is given by:
![A =s^2](https://tex.z-dn.net/?f=A%20%3Ds%5E2)
where, s is the side of the square.
As per the statement:
A square ceiling has an area of 360 square feet.
⇒A = 360 square feet.
then;
![s^2 = 360](https://tex.z-dn.net/?f=s%5E2%20%3D%20360)
⇒![s = \sqrt{360} =18.973666](https://tex.z-dn.net/?f=s%20%3D%20%5Csqrt%7B360%7D%20%3D18.973666)
Perimeter(P) of square is given by:
![P = 4s](https://tex.z-dn.net/?f=P%20%3D%204s)
then;
![P = 4 \cdot 18.973666 = 75.894664 \approx 76 ft](https://tex.z-dn.net/?f=P%20%3D%204%20%5Ccdot%2018.973666%20%3D%2075.894664%20%5Capprox%2076%20ft)
Therefore, 76 feet molding does he need.
Your equation for number one is 600,788,188/760,507,625 = x/100
After cross multiplying you will get 760,507,625x = 60,078,818,800
Then you will divide by <span>760,507,625 to isolate the varible to get 78.99 = x.
Your equation in number two is 80/143 = x/100 because when you subtract 143 by 63 you get 80, the amount of males in the room. Then you cross multiply to get, 143x = 8000. Then you would divide both sides by 143 to isolate the varible to get 55%</span>

Step-by-step explanation:
Answer:
4 km per hour and 6 km per hour.
Step-by-step explanation:
The combined running rate = 30/3 = 10 km/h.
If one runner's speed = x then the other one's speed is x+2 km/h.
So x + x + 2 = 10
2x = 8
x = 4
So one runs at 4 km/h and the other at 6 km/h.
