The number of ways or different menus containing 10 main courses that the restaurant can make out of the 15 main courses is calculated through the combination.
15C10
This is read as "combination of 15 taken 10" which can be calculated through the equation,
nCr = n! / ((r!) x(n - r)!)
In this item, n is equal to 15 and r is equal to 10.
Substituting the known values to the equation above,
15C10 = 15! / (10!)x(10 - 5)! = 3003
Thus, there are 3003 different menus that the restaurant can choose from.
Answer:
The surface area of the cube is 648.96 sq in.
Step-by-step explanation:
This problem is made a lot easier by the fact that it's a cube.
So we first calculate the area of one of the faces. The length of the side of the side is 10.4 inches, and <em>10.4 * 10.4 = 100.16.</em>
There are six faces, so we multiply the area of 1 face by 6. <em>100.16 * 6 = 648.96. </em>
Therefore, the surface area of the cube is 648.96 sq inches.

Answer:
The answer is about 10 hours. The recomened amount of sleep for school aged children between the ages of 6-13 years old is 9-11 hours of sleep per night.
16x – 30 - (<span>14x – 6) = 0
16x - 30 - 14x + 6 =0
2x - 24 =0
2x = 24
x = 12</span>
Well I would just do 8,304,088 + 90,000. So, that would equal 8,394,088 in all. Hope this helped!
