Answer:
1 ornament per 3 hours
in 15 hours she will have 7.5 of them done
If you are making 4 billion a second do 4,000,000,000 x 60 = 240,000,000,000
Then times that by 10 which equals. 2,400,000,000,000
Is the answer for the second one
6,000,000,000 x 60 x 60 x 2 = 1,296,000,000,000,000
Therefore the probability that the angle measure are supplementary are:120,60
That would be A.
This is called the Contrapositive :-
If A implies B then Not B implies Not A.
