We simply need to find a common denominator. The common denominator between the two (LCM/Least common multiple for denominator) is 24.

Now, we multiply the numerators also. We have our new numbers: 2 8/24 for October, 12/24 for November, and 3 9/24 for December. Now, we have to add them together. 2 8/24 + 12/24 = 2 20/24

Now, add the December value to the combined October/November values.

2 20/24 + 3 9/24 = 5 29/24

Now, we need to simplify the fraction.

6 9/24

Answer: 6 3/8 inches of rain occured in the three months.

Which complex number has a distance of (squareroot) of 17)) from the origin on the complex plane?
-BARSIC- [3]

Answer:

4-i

Step-by-step explanation:

The distance of a complex number

z=a+bi

from the origin is given by:

|z|=\sqrt{(a-0)^2+(b-0)^2}

|z|=\sqrt{a^2+b^2}

The length of  2+15i is;

=\sqrt{2^2+15^2}

=\sqrt{4+225}

=\sqrt{229}

The length of  17+i is;

=\sqrt{17^2+1^2}

=\sqrt{289+1}

=\sqrt{290}

The length of  20-3i is;

=\sqrt{20^2+3^2}

=\sqrt{400+9}

=\sqrt{409}

The length of  4-i is;

=\sqrt{4^2+1^2}

=\sqrt{16+1}

=\sqrt{17}

The correct choice is D
