Answer:
220 color combinations are possible.
Step-by-step explanation:
A combination is a way of selecting members from a grouping, such that the order of selection does not matter.
in our case we have 3-combinations of a set of 12 elements:
C(12, 3) = 12!/(3! (12-3)!)
C(12, 3) = 12!/(3! 9!)
C(12, 3) = (10*11*12)/(2*3)
C(12, 3) = 220 color combinations are possible.

The answer to this question would be 11 :)
Answer:
-30
Step-by-step explanation:
Substituting values of a and b in equation
3(-5)+2(-6)-3
-15-12-3
-15-15
-30
Answer:
Step-by-step explanation:
cos(20°) = (14/2)/x
x = 7/cos(20°) ≈ 7.45
I'm pretty sure it should be the 45. or A
