This is pretty much the worst problem I've seen this week. It's not quite a homework, but I think it fits requirements of homework-like problems. I spent 15 minutes on it and couldn't come up with any way to solve it and yet I need to know how to solve similar problems for tomorrow, and I don't want to spend day on working out just one problem. Here's a problem: Nine hundred students were asked whether they thought their school should have a dress code. A circle graph was constructed to show the results. The central angles for two of the three sectors are shown in the diagram. What is the number of students who felt that school should have no dress code? Then there's a cirle that shows: 25 degrees - Partial dress code 95 deg. - Full dress code X deg. - No dress Code Thanks, and please don't provide me with a clear answer but rather hint or way of doing,.
