Answer:what is the unit
Step-by-step explanation:
They aren't necessarily equal because, for example, 3/2 = 1 remainder 1 and 5/4 = 1 remainder 1 aren't equal because it takes 2 x 1 = 2 + 1 = 3 while 4 x 1 = 4 + 1 = 5. They are the same quotient and remainer, except they aren't used to check if it multiplys back to the same divended.
You can simply use a calculator (or a piece of paper and pencil!) for this equation, which is nice since it’s easy once you know how :)
To find a percentage of a number, we’ll need to multiply.
12.4% x 57.5 = 7.13
Therefore 12.4 percent of 57.5 is equal to 7.13.
Hope this helps you! :)
Substitute 136.5 for y.
![136.5=\frac{x(191-x)}{60}](https://tex.z-dn.net/?f=136.5%3D%5Cfrac%7Bx%28191-x%29%7D%7B60%7D)
![8190=x(191-x)](https://tex.z-dn.net/?f=8190%3Dx%28191-x%29)
![8190=191x-x^{2}](https://tex.z-dn.net/?f=8190%3D191x-x%5E%7B2%7D)
![x^{2} -191x+8190=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-191x%2B8190%3D0)
Compare this equation with ![ax^{2} +bx+c=0](https://tex.z-dn.net/?f=ax%5E%7B2%7D%20%2Bbx%2Bc%3D0)
a = 1, b = - 191, c = 8190
or
or
![x=\frac{191-\sqrt{191^{2}-4(1)(8190) } }{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B191-%5Csqrt%7B191%5E%7B2%7D-4%281%29%288190%29%20%7D%20%7D%7B2%7D)
or
![x=\frac{191-\sqrt{36481-32760 } }{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B191-%5Csqrt%7B36481-32760%20%7D%20%7D%7B2%7D)
or
![x=\frac{191-\sqrt{3721 } }{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B191-%5Csqrt%7B3721%20%7D%20%7D%7B2%7D)
or
![x=\frac{191-61}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B191-61%7D%7B2%7D)
or
![x=\frac{130}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B130%7D%7B2%7D)
x = 126 or x = 65
Hence, the points on the curve are (65, 136.5) and (126, 136.5).
The width of the air space is the distance between these points.
Width = ![\sqrt{(x_{2}- x_{1})^{2} +( y_{2}- y_{1}) ^{2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B2%7D-%20x_%7B1%7D%29%5E%7B2%7D%20%2B%28%20y_%7B2%7D-%20y_%7B1%7D%29%20%5E%7B2%7D)
= ![\sqrt{(126- 65)^{2} +(136.5-136.5) ^{2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28126-%2065%29%5E%7B2%7D%20%2B%28136.5-136.5%29%20%5E%7B2%7D)
= 126 - 65
= 61
Hence, width of the air space is 61m.
