Estimation Station #1

For the following questions, give an estimate that is within 10% of the correct answer. Aside from "million", "billion", and so forth, please use numerals only in your answer.
E.g., the population of earth could be accepted as 8 billion or 7800000000.
Due to the lack of punctuation in type-ins, 7.8 billion wouldn't work.
