dr calvin measured a piece of metal to be 0.00064. dr amos measured a piece to be 2.5 x 10^-5 of a meter thick if the docters combine pieces what would piece be

Question

fill in the blank

Answer 1

I am assuming that you are asking how long the two pieces will be if they are combined.  

 

First, write both numbers in the standard form.. The first one is already in the standard form.  The second one is in scientific notation, so we need to change it into standard form. 2.5 * 10 ^ -5 = 0.000025.

 

Add 0.000025 + 0.00064= 0.000665 in standard form.  In scientific notation it becomes 6.65 * 10^ -4

 

Now, you have an answer...
