20% of 10a is b. What percent of 2b is a?

All I have so far is 1/2b=a or 2a=b. Answer and explanation would really help. Thanks!

2. y=4/x
y=x-3
3. y=root x
y=x-6
4. y=|x|

Let f(x) = ln x for all x>0, and let g(x) = x^2-4 for all real x.
Let H be the composition of f with g, that is H(x)= f(g(x)).
Let K be the composition of g withf, that is K(x)= g(f(x)).

A.) Find the domain of H.
B.) Find the range of H.
C.) Find the domain of K.
D.) Find the range of K.
E.) Find H'(7).

Any help/pointers you can give me will be much appreciated, I've been working on this one for a while for the past few nights and cant make anything of it mainly because of the ln that they threw in there.

In a literature class, 30% of students speak French, 35% speak German and 50% of students speak French or German. What is the proportion of students who a speak French and German and who speak French but not German?

Also, please note I'm not looking specifically for an answer, but some guidance on how something like this should be approached. Perhaps a Venn Diagram type of problem? Thanks! :)
