Angles 7, 6, 3, 2 are all vertical angles, which mean they are congruent (equal)
so if angle 7 is 115° so are 6, 3, and 2
so the measure of angle 2 is 115°
Answer:
The ranking of the top three teams could occur in 720 ways.
Step-by-step explanation:
The order in which the teams are ranked is important, that is, for example, Oilers, Flames and Canucks is a different outcome of Oilers, Canucks and Flames. This means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
![P_{(n,x)} = \frac{n!}{(n-x)!}](https://tex.z-dn.net/?f=P_%7B%28n%2Cx%29%7D%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n-x%29%21%7D)
In how many ways could the ranking of the top three teams occur?
Three teams from a set of 10. So
![T = P_{(10,3)} = \frac{10!}{7!} = 720](https://tex.z-dn.net/?f=T%20%3D%20P_%7B%2810%2C3%29%7D%20%3D%20%5Cfrac%7B10%21%7D%7B7%21%7D%20%3D%20720)
The ranking of the top three teams could occur in 720 ways.
If you multiply out the answers, which is easier, then you can find the correct answer.
The factors need to multiply together to create the original problem, so it's just a matter of plug and chug.
The answer is B.
Answer:
3619.11 cubic inches
Step-by-step explanation:
volume of a cylinder is ![V=\pi r^2h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2h)
diameter is 16 in, so radius (r) is 8 in
plug in values:
cubic inches
