First we have to see in both cases what is the cost of one ticket
in the fist case 12.5/5=2.5
in the second case 20.16/8=2.52
therefore 5 tickets for 12.5 is the better deal
When a circle's diameter is 1, its circumference is π.
If m ACD = 30 => m DCB = 60.
In triangle ACD:



AC^{2}+CB^{2}=AB^{2} => AB=

=32.
=> P=16+32+

=48 +

.
They won 20/30, so 100 / 30 = 3.3, then times by 20 = 66.66.
Hope this helps.
Answer:
The answer is 5/6, or .833, 3 repeated.
Step-by-step explanation:
The 4 is only one side of the die, or 1/6 if the surface of the die. So the other part that is left is the other 5/6 of the surface.
