The answer is 6.601, and therefore, the second option.
<u></u>There are two way sof doing this question:
<em><u>1st solution is : </u></em>
<em> </em><u><em>6/15 = 2/</em></u><u /><em><u>5</u>
</em>because 6/15 is divisible by 3 and it is done by this form :
3 X 2 = 6
and
3 X 5 = 15
<em><u>2nd solution is:
</u></em><u></u>6/15 = 2/?
here we suppose that the missing value is <em>x:
</em> 6/15 = 2/x
you shift the denominators and then multiply them by the their numerators:
6 * x = 15 * 2
6x = 30
now you divide 6 on both sides:
<em> </em>6x/6 = 30/6
<em><u>x = 5</u></em><em>
</em>
Simply put 10 in all of the boxes. There are 5 boxes. And all those boxes equal 50, right? So for every box, there's 10 students. 10 multiplied by 5 is equal to 50.
8 and 4 are corresponding angles
Remember your prefixes! They help a lot, because there is a formula for this particular problem. Nonagon refers to a shape with 9 sides.
The number of triangles a polygon has is represented by the formula:
(n-2)
Where "n" is the number of sides. If you ever forget what you subtract "n" by think of a triangle. It has 3 sides, so it is only logical that you should only have 1 triangle (subtract by 2). So, what is the sum of the interior angles of a triangle, 180°. So the formula looks like this:
Sum of Interior Angles = 180°(n-2)
180°(9-2)
180°(7) = 1260° is the sum of interior angles for a nonagon!
