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.

Answer:
HL Theorem
Step-by-step explanation:
Both triangles are right, as indicated by the right angles. Two other pairs of sides are marked congruent, one of them being the hypotenuse, the other a leg.
The theorem requires right triangles, congruent hypotenuses, and a congruent pair of legs. The triangle satisfies all three conditions.
Answer:
Step-by-step explanation:
Let y represent the number of yellow sweatshirts sold. Then the total revenue is ...
$11.95(25 -y) +$12.50(y) = $304.25
$0.55y +$298.75 = $304.25 . . . simplify
$0.55y = $5.50 . . . . . . subtract $298.75
y = 10 . . . . . . . . . . divide by $0.55
25-y = 15 . . . . the number of white sweatshirts sold
10 yellow and 15 white sweatshirts were sold.
