Umm they are bonus questions for a reason, so you can look for them, not have someone else do them for you. Sorry I am a mom! For the 1st one you can look up the US Census report by doing a search you should find that one easy. Plus the number just reached a record and was all over the news as a hint!

Answer 4

why don't you start with Google.com and learn how to research and get some answers yourself? Answers.com is not a site to learn how to cheat on your homework. It's not fair to the rest of the class for you to have adults answering your questions and then you get all the bonus points.

Answer 5

well im pretty sure that the US population just recently breeched the 300 million mark
