D I believe because if you look at point B it is (3,3) but dilated to (9,9) and 9/3=3. Which also means that the side lengths will be 3 times the original triangle’s side lengths
Pi r^2 h
Divide 10 by 2 to get the radius.
pi 5^2 9
pi 25 9
225 pi is the answer
1, because the two lines on the side hit eachother,
so those arent paralell but the top and bottom are paralell because they dont touch
We have been given that there are 125 people and three door prizes.
In the first part we need to figure out how many ways can three door prizes of $50 each be distributed?
Since there are total 125 people and there are three identical door prices, therefore, we need to use combinations for this part.
Hence, the required number of ways are:
![_{3}^{125}\textrm{C}=\frac{125!}{122!3!}=\frac{125*124*123}{1*2*3}=317750](https://tex.z-dn.net/?f=_%7B3%7D%5E%7B125%7D%5Ctextrm%7BC%7D%3D%5Cfrac%7B125%21%7D%7B122%213%21%7D%3D%5Cfrac%7B125%2A124%2A123%7D%7B1%2A2%2A3%7D%3D317750)
In the next part, we need to figure out how many ways can door prizes of $5,000, $500 and $50 be distributed?
Since we have total 125 people and there are three prices of different values, therefore, the required number of ways can be figured out by using permutations.
![_{3}^{125}\textrm{P}=\frac{125!}{122!}=125*124*123=1906500](https://tex.z-dn.net/?f=_%7B3%7D%5E%7B125%7D%5Ctextrm%7BP%7D%3D%5Cfrac%7B125%21%7D%7B122%21%7D%3D125%2A124%2A123%3D1906500)
It's a very simple question if you can get your head around the decimals, you could do this using the bus stop method which you can find if you Google.
I have worked out the answer for you;
58.59 / 9.3 = 6.3
I hope this helps, if you are looking for an easier way to solve this issue then let me know! There are others ways too!
