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.

False.
The dilation factor can be 1 or less in magnitude. If it is 1, the size remains unchanged. If it is less than 1, the image is smaller.
Answer:
2.43 (units)
Step-by-step explanation:
Circumference of a circle is defined by C=2pi*r
Solving that equation for r --> 5.5 = 2* 3.14 * r
r=0.88 unit
Area of a circle = A= pi * r^2
Solve this equation by plugging in the r we just found. A = 3.14 * (0.88^2)
Answer: 2.43 units
