Answer:
I think 3
Step-by-step explanation:
I'm not totally for sure about it though. sorry :(
You would divide 27/6.75.
You'd get 4, so 4 people went.
To check you would do 4x6.75 and your get the total of 27$
8/14 , 12/21, 16/28, 20/35
7? Is seems that the 4 is being added with +2 when it got bigger so I’m thinking the 5 would be the same thing +2 equals 7..that’s what I’m thinking
Answer:
3003
Step-by-step explanation:
The number of differents menus containing 10 main courses that the restaurant can make if it has 15 main courses from which to chose is calculated through the combination: 15C10. The formula of the combination is: nCr = n! / ((r!) x(n - r)!)
Where r=10 and n=15
Substituting the values to the equation: 15C10 = 15! / (10!)x(10 - 5)! = 3003
Then there are 3003 different menus that a restaurant can makeif it has 15 main courses from which to choose.
