Answer:
6720 ways different
Step-by-step explanation:
In this case, we must calculate the different ways using the permutation formula:
nPr = n! / (n - r)!
where n is the total number of people and r would come being the group of person that you want to put together the groups, therefore n = 8 and r = 5
replacing:
8P5 = 8! / (8 - 5)!
8P5 = 6720
That is to say that there are 6720 ways different winning groups are possible
So hmmm check the picture below
now
![\bf V=\pi 9^2\cdot \cfrac{1}{4}\implies V=\cfrac{81\pi }{4} \\\\\\ \textit{there are }27ft^3\ in\ 1yd^3\textit{ thus, let's convert them to }yd^3 \\\\\\ \cfrac{\frac{81\pi }{4}}{27}\iff \cfrac{\frac{81\pi }{4}}{\frac{27}{1}}\implies \cfrac{81\pi }{4}\cdot \cfrac{1}{27}\implies \boxed{\cfrac{3\pi }{4}}](https://tex.z-dn.net/?f=%5Cbf%20V%3D%5Cpi%209%5E2%5Ccdot%20%5Ccfrac%7B1%7D%7B4%7D%5Cimplies%20V%3D%5Ccfrac%7B81%5Cpi%20%7D%7B4%7D%0A%5C%5C%5C%5C%5C%5C%0A%5Ctextit%7Bthere%20are%20%7D27ft%5E3%5C%20in%5C%201yd%5E3%5Ctextit%7B%20thus%2C%20let%27s%20convert%20them%20to%20%7Dyd%5E3%0A%5C%5C%5C%5C%5C%5C%0A%5Ccfrac%7B%5Cfrac%7B81%5Cpi%20%7D%7B4%7D%7D%7B27%7D%5Ciff%20%5Ccfrac%7B%5Cfrac%7B81%5Cpi%20%7D%7B4%7D%7D%7B%5Cfrac%7B27%7D%7B1%7D%7D%5Cimplies%20%5Ccfrac%7B81%5Cpi%20%7D%7B4%7D%5Ccdot%20%5Ccfrac%7B1%7D%7B27%7D%5Cimplies%20%5Cboxed%7B%5Ccfrac%7B3%5Cpi%20%7D%7B4%7D%7D)
now, that's how many yard³ are there for that slab, now, how much is the cost?
well, each yd³ costs $40, thus
49.3:6=8.21
-48
1.3
-1.2
0.1
Answer:
you domb if you dont know the answer B

Step-by-step explanation:
3 + 4x + 2 + 2x + 2x
5 + 4x + 2x + 2x
5 + 8x
8x + 4 - 3 - x
7x + 4 - 3
7x + 1
