Science & Mathematics - 4 January 2007

Hi there, some time ago I worked on alcohol separations by Carbowax 1500 packed GC using FID and N2 as carrier. The alcohols are methyl, ethyl and 1-butyl. Somebody told me that there's an equation that relates the %mole to the %area, obviously there's an equation for each alcohol. And I'm going mad trying to find them. So the question is: can you tell me the equations, for god's sake?

Please help me...!!!!!!

please help finding these answers to these questions.

1. What unusual result occurs when writing the repeating decimal 7.9 (the 9 has a - on top of it) as a fraction in lowest terms?

2.Beth Roberts and her construction crew are adding a recreation room to a house. They have used a tape measure to determine if two walls are at right angles to each other. Their measurements of the sides of the triangle in the corner between the two walls are 10 in., 10 in., and 13.4 in. Do the walls meet at a right angle? Explain your answer.

3. Write a trinomial that represents the area of the rectangle. The rectangle cannot be typed so here is how the rectangle looks like: the Height if the Rectangle is 2√7 and the width(wide) is 5√7

4. What is the smallest integer of x that will give positive values for the length and the width of the rectangle? the Height if the Rectangle is 2√7 and the width(wide) is 5√7

please write the number down so I can tell which answer is to what number.

thank you

USING AN INDIRECT PROOF: prove that there cannot be a triangle in which the trisectors of an angle also trisect the opposite side.

I do not know how to do this. Can someone show me how? And I mean show. Not just give me the answer because I want to learn.
