It show the planets shrunken down ten times and the atom magnified ten times. Everything lines up the same! My husband saw it on Discovery or something and has been trying to find a copy for years. Maybe that isn't the exact title, but you may have an idea of what I'm looking for. Thanks

Apparently you need to let e^x = u
Then solve it as a quadratic using the quadratic formula
But I can't see how!

Problem 1:
Orange Thirst is 15% orange juice and Quencho is 5% orange juice. how many liters of each should be mixed together in order to get 100 L of a mixture that is 12% orange juice?

Problem 2: A motorboat took 4 hours to make a trip downstream with a 6-mph current. The return trip against the same current took 5 hours. Find the speed of the boat in still water. (Use distance=rate x time)

Thanks. Don't solve it. Just need the equations. :)

I understand what the following question is trying to say, but I'm not sure how to explain it.

You are helping a friend move furniture. The friend asks you to stand inside the back of a pickup truck to hold a piano because there is no rope available to tie it to the truck. Explain why you should refuse this request. Your answer should show that you understand the reasoning used by Galileo and Newton.

Words such as inertia, mass, etc. should be used. Please help me explain this. Thanks :)

What are the chances of seeing two shooting stars at exactly the same time traveling right next to each other in the same exact direction, appearing at the same time and disappearing at the same time? The chances of this happening seems slim to me, and it happened to have happened after asking G-d for a sign, i don't care whether you believe me or not, but just tell me, is it likely?
