    Answer:

    A. The answer is 165.85.                                                                                        B. The best answer is 1.435 ·103 because while they both are really small for a rail road track that one is bigger. the final answer for that is 147.805mm.

    Step-by-step explanation:

    (3.9 x 10³³) / 1  =  X / (2.45 x 10⁵)  .

    Solve that proportion for ‘ X ‘ in the usual way.

    If you can’t remember how to solve a proportion, then  

    THAT’s what you have to go look up.  It’s much more

    important to you right now than how much energy the  

    sun is putting out.

    7.4 x 10⁴ mm is the same size as about 243 feet !

    If the tracks on a DVD were that far apart, there would not be  

    room for very many tracks on a DVD.  That’s not reasonable.

    If the tracks are  7.4 x 10⁻⁴ mm apart, then there are about  

    34,000 tracks in a stripe that’s 1-inch wide.  I have no idea

    how they do this, but it’s certainly more reasonable than the  

    other choice.                                                                                                                      Hope this helps! Can you please give me Brainleist?
