Answer:
99 ways
Step-by-step explanation:
Let's say the the 11 courses are labeled a, b, c, d, ect. The possible chances of A bieng combined with another 9 appetisers is 9. Then B is combined with 9 appetisers. The C is combined with 9 appetisers and so on and so on. Meaning of there are 9 appetisers you times it by 11 main courses it means there will be 99 ways to make two course mean with one appetiser and one main course.
I am not 100% sure this is correct but this is what I think.
Answer:
x=1
Step-by-step explanation:
Its x=1 because if we put the 1 as in x then it will be like 2(1)+3(4(1)-3)= 8-3(1)
2(1)+3(4(1)-3) is equal to 5
8-3(1) is equal to 5
5=5
so x is 1
Answer:
Step-by-step explanation:
21.7
Use the cosine function, which is the ratio (adjacent side) / (hypotenuse).
Here we have cos 37 degrees = adj / hyp = 17.3 / x, and so
x 1
------ = -------------------
17.3 cos 37 deg
Then the hypotenuse length, x, is 17.3 / 0.799 = 21.7
You mean five thousand and eight hundred? If so, then the answer is = 5800
