-7(1 + 7n) = 36 - 6n
-7(1) - 7(7n) = 36 - 6n
-7 - 49n = 36 - 6n
<u>     +49n       +49n</u>
         -7 = 36 + 43n
<u>       -36   -36            </u>
        <u>-43</u> = <u>43n</u>
         43     43

lisabon 2012 [21]
<h3>Answer: C) incenter</h3>

========================================

Explanation:

If you were to intersect the angle bisectors (at least two of them), then you would locate the incenter. The incenter is the center of the incircle which is a circle where it is as large as possible, but does not spill over and outside the triangle. Therefore this circle fits snugly inside the triangle.

--------------

extra notes:

* The centroid is found by intersecting at least two median lines

* The circumcenter is found by intersecting at least two perpendicular bisector lines

* The orthocenter is found by intersecting at least two altitude lines

* The incenter is always inside the triangle; hence the "in" as part of the name. The centroid shares this property as well because the medians are completely contained within any triangle. The other two centers aren't always guaranteed to be inside the triangle.

* The red lines cut each angle of the triangle into two equal or congruent pieces.

Eva8 [605]

Answer:

  • 3/4 gallons

Step-by-step explanation:

Let the capacity of the bin is x gallons.

1/2 gallon is 2/3 of x

<u>Convert this into equation and solve for x:</u>

  • 1/2 = 2/3x
  • x = 1/2 : 2/3
  • x = 1/2 * 3/2
  • x = 3/4

3/4 gallons of water will fill the bin
