Question

Which of the following is a quantity that could be represented by the number 2*10^-3

A.
the diameter (in meters) of an atom
B.
the time it takes (in minutes) to blink
C.
the occupancy limit of a pizza restaurant
D.
the annual salary of a high school math teacher

Answer 1

what do you think the answer is?

Answer 2

i would say D

Answer 3

No, the number is very small...10^-3 means 1/1000 or as a decimal .001

So 2 x 10^-3 = 2 x 1/1000 = 2/1000 or .002

That is not the salary for a teacher.

.002 is a number a drop bigger than 0, so to say.

So whats the correct answer?

Answer 4

A

Answer 5

is that correct?

Answer 6

I would say B. I think the diameter of an atom is way smaller than 2/1000 of a metr. If I am correct, the diameter of an atom is about a million times smaller than the thickest piece of hair on your head. So I would say, B.
