Find the smallest positive integer x such that, if the rightmost digit of x is moved to the leftmost position (for example, x = 1234 would change to 4123) the new number is exactly equal to 2x.

Note: an infinite number of integers have this property. I just want the first one.

OK, here's the experiment.

You have two cups of water. One has green (just food coloring, no effect), salty, cold water and the other cup has hot red (food coloring) water. You put a little slip of paper on top of the green colored cup and you flip the red colored cup on top of it upside down quickly. Now, you have the green on the bottom and the red upside down on the top with a card separating them both. You take the card out, and what happens? You would think they would mix, but instead they stay right where they are? I need two questions answered...

1. Why did the hot red water stay on the top and not mix with the green water? (Hint: has to do with solids, liquids and gases)

2. Why did the green, salty, cold water stay on the bottom? (Hint: Has to do with chemical changes)

If you can help me, it would be greatly appreciated, because I am very confused. Thanks so much!!!!!

Using the formula, A=P[1+(r/h)]^(nt), let r = 10%, p=1, n=1 and give the coordinates (t,a) for the points where t=0,1,2,3,4. Round your answer to the hundreth's place.

what are the coordinates?

Can you please show me the steps to get the answer??

What is the pressure of a mixture of helium, nitrogen, and oxygen if their partial pressures are 60 mm Hg 150 mmHg and 120 mmHg.

My teacher gave us this equation:
Ptotal=P1+P2+p3

600+150+102+150=1002

so then would you divide 1002 by four to get the partial pressure of al the gases?
