The correct answer is option C.
Answer:
B. 
Step-by-step explanation:
We are told that the smallest object visible with our eyes is similar to the width of a piece of hair, which is
meters wide.
Using an optical microscope, we can see items up to
meters wide.
To find the objects we can see with our eyes are how much larger than the objects we can see with an optical microscope, we can set an equation as:

Using the exponent rule of quotient
we will get,





Therefore, the objects we can see with our eyes are
times larger than the objects we can see with an optical microscope and option B is the correct choice.
Answer:
look down below
Step-by-step explanation:
We know that AB = DC, and BC = AD, ∠B = ∠D because they are given
So, ΔABC ≅ ΔCDA because of SAS congruency
21/50; 420/1000=42/100 simplify it and it is 21/50
Y = -2x+0
I don't think you need to add the 0 though.
