Mind helping me out on one of these problems? If 10,000 microns=1 cent. and 100,000,000 angstrom units=1 cent. how many angstrom units equal 1 micron? Answers: A. 0.00000000000000001 or something, but you know it is wrong B) 0.0001 C) 10,000 D) 100,000 E) 1,000,000,000,000 At first, I chose B) because I divided microns by angstroms. So how do you solve this kind of problem?? These are usually the problems that I have difficulty on. I know I'm dumb. xD Hey if anyone here has the BlueBook then can you turn to page 337. I have a question on #6. I got the right answer the first time because: Since all triangles are .5bh and the base is all the same (radius line seg. OX), then all you would need to consider is the height right? Please answer this: Do you find all triangles' area from the equation 1/2bh?? Does it apply to any type of triangle? You find the height from the vertex of a corner of a triangle correct? and it has to be perpendicular to the base? Thanks a lot guys!
