The common denominator of these fractions will be 12. So Ann worked 306/12 hours, Mary worked 244/12 hours, and John worked 123 hours, meaning they have worked 673/12 hours together.
Answer:
4
Step-by-step explanation:
C, it is a many-to-one function since it is symmetric about the line x=0.75.
For instance f(0.5) = f(1) meaning the x-values 1 and 0.5 both map onto the same y-value.
Answer:
33%
Step-by-step explanation:
If you add all them together you get 24 right? Then do 8/24 then you get 0.3333333
