A dollar bill is 15.5 cm long. If 7 trillion dollar bills were laid end to end around the earth's equator, how many times would they encircle the planet? Radius of planet = 6,378 km.

I keep trying it but I always end up at the number of bills, and the way I'm working it would just give me that answer and then back to the circumference. Can someone tell me how to set this up?

On a lab I should have gotten 7.8 * 10^7 but I got 1.2 *10^6. Do I have to look at the number preceding the power or just see if the power that it is raised to is within 1?

EG - I know that if I would have gotten say 8.0 * 10^7 that would be within a power of 10 but is 1.2 too little? Am I over thinking this way too much?

Why or why not? What do you think really crashed? Maybe it was an aircraft secretly made for the army?
What's your opinion?

My parents' friends come to stay at our house during the day to take a nap sometimes. She will usually clean up for them or cook them a delicious dinner. Well, her husband is a witch or whatever. No one eats her food usually cuz we suspect she is doing something. One time we found a square of dirt under the chair in the living room. In the dirt were panties and magnet ABCs. We just threw it away cuz it was weird and we didn't know who did it. (There was usually a lot of people at the house all the time) I just think she is doing something evil in the house. I can't do anything to keep her away but what do I do to get rid of this? Oh yeah one time she sent me some posole to eat one time and there was some plastic thing in it. I mean she is weird. The last time I saw her, she gave me an evil evil look. It may sound paranoid and think what you want, but I would like some help. You can email me(display name on here @yahoo.com) if you don't want to post on here. Only serious people pleez.
