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.

Solve using the pathagorean theorem​
seropon [69]

Answer:

2 sqrt(13)

Step-by-step explanation:

We can find the hypotenuse using the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

4^2 + 6^2 = c^2

16+36 = c^2

52 = c^2

Taking the square root of each side

sqrt (52) = c

sqrt(4*13) = c

2 sqrt(13) = c

There is a bag filled with 4 blue and 5 red marbles.
gavmur [86]

1) first pick red 5/9 blue 4/9


2) second pick when red has been picked red now becomes 4/8, blue stays 4/8


2) Second pick when blue has been picked blue now becomes 3/8, red stays 5/8


Mind you, you only need both different colours so:

first pick red 5/9 x sec pick blue 4/8 = 20/72

and first pick blue 4/9 x sec pick red 5/8 = 20/72

add both up 20/72 + 20/72 = 40/72 = 5/9

The sum of the measures of angle LMN and angle NMP is 180 degrees
Vaselesa [24]

Answer:

angle LMN is 153 degrees.

Step-by-step explanation:

180 = 15g + 18 +3g; combine like terms

180 = 18g + 18; subtract 18 on both sides

162 = 18g; divide 18 on both sides

g = 9

plug in: 15(9) + 18 = 153
