@Eyad would you help me?

Answer 4

a) should be the other way around, so Kendra is correct

It should be RW = 2/3*RU


This is because the medians meet at a point which cuts each median into two parts that are 2:1 in ratio (ie one part is double the other)

Answer 5

1a) In this triangle, the 3 perpendicular bisectors cross themselves @ the point W. So, you can write that :

(1) : UW = (1/3)RU

(2) : VW = (1/3)VS

(3) : TW = (1/3)TQ


You can see that :

RW = RU - UW, but according to the equation (1) : UW = RU/3

RW = RU - (1/3)RU

RW = (3/3)RU - (1/3)RU

RW = [(3 - 1)/3]RU

RW = (2/3)RU

(2/3)RW = (2/3)(2/3)RU

(2/3)RW = (4/9)RU

So we can say that the Jordan's comment is wrong. Kendra disagrees. I'm not agree with Jordan.


1b) You can see that :

QW = QT - TW, but according to the equation (3) : TW = (1/3)TQ

QW = QT - (1/3)TQ

QW = (3/3)QT - (1/3)TQ

QW = (3/3)QT - (1/3)QT

QW = [(3 - 1)/3]QT

QW = [2/3]QT

[2/3]QT = QW

QT = (3/2)QW, if QW = 27 inches

QT = (3/2) * 27

QT = 81/2 (inches)

Answer 6

Woah.. @thank YOu

Answer 7

Yw @Trexy :D

Answer 8

thanks @Eyad and @jim_thompson5910

Answer 9

yw

Answer 10

so Kendra is Correct right?

Answer 11

yes

Answer 12

Part B is 81/2 or 40.5

Answer 13

that's correct

Answer 14

you can verify by taking 2/3 of QT = 40.5 to get QW = 27

Answer 15

because its asking for Round to the nearest tenth if necessary. so for the part B it will be 40.5?

Answer 16

yes

Answer 17

thank you

Answer 18

sure thing
