<p>Mind helping me out on one of these problems?</p>

<p>If 10,000 microns=1 cent. and 100,000,000 angstrom units=1 cent.
how many angstrom units equal 1 micron?</p>

<p>Answers:
A. 0.00000000000000001 or something, but you know it is wrong</p>

<p>B) 0.0001</p>

<p>C) 10,000</p>

<p>D) 100,000</p>

<p>E) 1,000,000,000,000</p>

<p>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</p>

<p>Hey if anyone here has the BB 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?</p>

<p>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? </p>

<p>Thanks a lot guys!</p>

<p>the answer is C: 10,000</p>

<p>since you know each equation equals 1 cent, set 10,000 microns equal to 100,000,000 angstroms. divide both sides by 10,000 to get 1 micron=10,000 angstroms.</p>

<p>hope this helps!</p>

<p>Oh ok, I guess I got mixed up with which one to convert. So basically you can set anything equal to something if they are equal to the same thing o_0</p>
