yes what about him if you want i can get him over here to help

disco619 · Answer

Im still figuring it out. But I do know that...
$$\frac{ 2 }{ 3 } \times RW \neq RU$$

anonymous · Answer

So Kendra is correct.

disco619 · Answer

Yea

anonymous · Answer

Whats the reasoning?

anonymous · Answer

http://www.wolframalpha.com/ this is a good math website try itit will come in handy later

for you Nick

anonymous · Answer

that website made no sense. at all

disco619 · Answer

I will not tell you the reason according to the Question but I can tell you this...

|dw:1386530426402:dw|

$$\frac{ 2 }{ 3 } \times 4 = 10$$
$$\frac{ 8 }{ 3 } = 10$$
$$2.66666 = 10$$
$$2.66666 \neq 10$$
It is not anywhere equal to 10

disco619 · Answer

You know what, you should ask someone else about this question as Im out of practice and a mistake would be fatal for you.
@ranga Can you do this?

@Hello_Im_Nick  Ranga is helping someone, he should be here in 3-5 mins...

anonymous · Answer

Thank you...

anonymous · Answer

@ranga  Do you know how to do this?

ranga · Answer

The line connecting the vertex to the midpoint of the opposite side is called a median. Here, QT, RU and SV are the medians. The three medians of a triangle intersect at a point called the centroid. W is the centroid. The centroid divides the median into two segments in the ratio 2:1. RW = 2WU. 
Or, RW = 2/3RU and not the other way around.    2/3RW is not RU as stated by Jordan because RU is longer than RW and therefore RU cannot be a fraction (2/3) of RW.

ranga · Answer

For the second part, 
QW = 2/3QT
we need to find QT
multiply both sides by 3
3QW = 2QT
divide both sides by 2
3/2QW = QT
QT = 3/2QW
QW = 27
QT =3/2 * 27 = 81/2 = 40.5 
QT = 40.5 inches.
