Iam in 6th grade not high school. but here is my question.
which is not determined by the type and arrangement of atoms in a mineral?
a.
its position on a hillside
b.
thermal properties
c.
electrical properties
d.
magnetic properties

I don't believe this question is a math question but I believe the answer is A.

Hope this is the answer and next time, post a question likes this in science.  This seems like a science question.

Which would not be determined by the type and arrangement of atoms in a mineral?

Let's go through this, and see which one works.

a) Its position on the hillside.
I believe that your answer is (A) because it doesn't really matter where on a hill you find it, it depends on its properties.

b) Thermal properties.
This isn't the answer because you need to know its thermal properties to determine what mineral it is.

c) Electrical properties.
This is one of the ways that you can figure out what type of mineral it is, so this factor is important, therefore making it an incorrect answer.

d) Magnetic Properties
This is another way that you can find out what type of mineral it is, making this factor important, so this is also an incorrect answer.

Your answer is A) Its position on a hillside.
