the problem states that r=.5

That may work, let me see if I get it right.

Don't get mad at him or her just because you are frustrated with your math. Its not that your being ignored. People may not know how to do your problems.

Thank you so much! It worked! I gave you best response.

Also @amistre64 helped you as much as he could on the last problem without giving you the answer. Which is the same thing I did here.

anonymous · Answer

No, he's being a little nuisance because instead of just saying in his head, "Oh, I don't know how to do that", he went out of his way to reply and say he doesn't know how.

Sleepyjess, seriously don't get all dramatic. I did get frustrated and it's not my fault if the mod couldn't make sense.
