Area of each piece of paper is
![8\frac{1}{2}\times11=\frac{17}{2}\times11=\frac{187}{2}](https://tex.z-dn.net/?f=8%5Cfrac%7B1%7D%7B2%7D%5Ctimes11%3D%5Cfrac%7B17%7D%7B2%7D%5Ctimes11%3D%5Cfrac%7B187%7D%7B2%7D)
Greatest number of possible piece of paper is
Answer:
c ≥ 10 dozen
Step-by-step explanation:
Victor wants to have at least 10 dozen cookies for the bake sale.
In layman terms it can be understood as that Victor wants either 10 dozen cookies or more than that such as 11, 12, 13, 50 , 100 whatever number is greater than 10.
Let the no. of dozen of cookies wanted by him is c
according to condition
if victor wants either 10 dozen cookies
it can be represented mathematically as
c = 10 dozen (1)
_____________________________________
If victor wants no. of dozens of cookies greater than 10 .
it can be written as
c >10 dozen (2) (">" is symbol for greater than . expression simply means value of x should be greater than 10)
______________________________________________
now combining equation one and two, we have
c ≥ 10 dozen . It can means that x can take value starting from 10 to any no greater than..
They can be derived by using calculus(integration to be precise)
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
![= \frac{circumference }{diameter}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7Bcircumference%20%7D%7Bdiameter%7D%20)
(its how pi is defined)
so that gives circumference
to get area , you use integration
![of an elemental ring of radius r and thickness dr and integrate it](https://tex.z-dn.net/?f=of%20an%20elemental%20ring%20of%20radius%20r%20and%20thickness%20dr%20and%20integrate%20it)
![A= \int\limits^0_r {2 \pi r} \, dr](https://tex.z-dn.net/?f=%20A%3D%20%5Cint%5Climits%5E0_r%20%7B2%20%5Cpi%20r%7D%20%5C%2C%20dr%20)
that gives the area.
if you don't know calculus yet ,dont worry, just remember the formulae.
Answer: y = 1/2x
Step-by-step explanation: I looked at the graph to find this. Look at the points (0,2) and (2,3). You will get 1/2 because you move up by 1 and move along the x-axis 2 places. I hope this helps, have a nice day.
