The expression b/c=b/c is an example of a(n)?

bc=cb

It is an example of commutative property.

Step-by-step explanation:

The given expression

By cross multiplying we can write given expression as

  a+b=b+a

We can write commutative property in multiplication

        ab=ba

Therefore, by using commutative property  then we get

         bc=cb

Hence, the given expression is an example of commutative property.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
