Answer:
1
Step-by-step explanation:
Let us consider the case of 3 numbers: x, y, and z.
Then x/x+y+z + y/x+y+z + z/x+y+z = x+y+z/x+y+z = 1
The same works also for any quantity of numbers.
You should draw a picture to visualize the problem easier.
The circumference of inner circle = 44 ft
That means the radius of the inner circle:
2*pi*r = 44
r = 44/(2pi) = 22/pi
Using the picture you hopefully drew, we see that the radius of the outer circle:
22/pi + 2
To figure out the circumference of the outer circle:
2pi*(22/pi + 2) = 44 + 4pi
So how much bigger is the the circumference of the outer circle than the inner circle?
44 + 4pi - 44 = 4pi
It is 4pi bigger or 4 * (3.14) = 12.56 feet
Since you don't provide the coordinates of the point W, I will help you in a general form anyway. In the Figure below is represented the segment that matches this problem. We have two endpoints U and V. So, by using the midpoint formula we may solve this problem:
![Midpoint=W=W(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2})=W(x_{3}, y_{3}) \\ \\ where:\\ \ U=U(x_{1}, y_{1}) \ and \ V=V(x_{2}, y_{2}) \\ \\ and: \\ x_{3}=\frac{x_{1}+x_{2}}{2} \\ y_{3}=\frac{y_{1}+y_{2}}{2}](https://tex.z-dn.net/?f=%20Midpoint%3DW%3DW%28%5Cfrac%7Bx_%7B1%7D%2Bx_%7B2%7D%7D%7B2%7D%2C%20%5Cfrac%7By_%7B1%7D%2By_%7B2%7D%7D%7B2%7D%29%3DW%28x_%7B3%7D%2C%20y_%7B3%7D%29%20%5C%5C%20%5C%5C%20where%3A%5C%5C%20%5C%20U%3DU%28x_%7B1%7D%2C%20y_%7B1%7D%29%20%5C%20and%20%5C%20V%3DV%28x_%7B2%7D%2C%20y_%7B2%7D%29%20%5C%5C%20%5C%5C%20and%3A%20%5C%5C%20x_%7B3%7D%3D%5Cfrac%7Bx_%7B1%7D%2Bx_%7B2%7D%7D%7B2%7D%20%5C%5C%20y_%7B3%7D%3D%5Cfrac%7By_%7B1%7D%2By_%7B2%7D%7D%7B2%7D%20)
Therefore:
![x_{2}=2x_{3}-x_{1} \\ y_{2}=2y_{3}-y_{1}](https://tex.z-dn.net/?f=%20x_%7B2%7D%3D2x_%7B3%7D-x_%7B1%7D%20%5C%5C%20y_%7B2%7D%3D2y_%7B3%7D-y_%7B1%7D%20)
So we know
but we also must know ![x_{1} \ and \ y_{1}](https://tex.z-dn.net/?f=x_%7B1%7D%20%5C%20and%20%5C%20y_%7B1%7D)
Finally, knowing the points U and W we can find the endpoint V.
Basically there are 3 addition properties and they are associative property, identity property, and commutative property.
Commutative property is just changing the order of the addends. Example: 26+19+34+21= 21+34+19+26
Identity Property is just adding a 0 to the number that doesnt change anything. Example: 26+19+34+21 +0 = 100
Associative property is just changing the grouping of the addends. Example: (26+19) + (34+21)
I know these properties may be complicated i know inhate them too haha but i hope i helped :) if you want you can search up the distributive property too but its with multiplication and addition combined and its harder but i think these are the 3 main properties.
