V/LW=H , you have to isolate the h so you must divide both sides by LW

Convert 2 1/5 to an<br> improper fraction.

DochEvi [55]

Answer: 11/5

Step-by-step explanation:

you would do (2) times (5) to get 10.

then you'd add 1+10 to get 11.

write this new number as the numerator... 11/5.

The centroid of a triangle is at (8, 7). One vertex of the triangle is at (0, 1). What is the midpoint of the side opposite this

RideAnS [48]

Answer:

(12,10)

Step-by-step explanation:

Let the midpoint of the side opposite this vertex have coordinates B(a,b)

We have the centroid at C(8,7) and the vertex of the triangle at A(0,1).

The centroid divides AB internally in the ratio 2:1

We use the formula:

$(\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})$

where m:n=2:1 is the ratio of internal division.

We substitute the coordinates of A and B and the ratio to get:

$(\frac{2a+1*0}{2+1},\frac{2b+1*1}{2+1})$

This should simplify and give us the centroid.

$(\frac{2a}{3},\frac{2b+1}{3})=(8,7)$

This implies that:

$\frac{2a}{3}=8,\frac{2b+1}{3}=7$

We solve for a and b

$2a=24,2b+1=21$

$a=12,b=10$

Therefore the midpoint of the side opposite this vertex is (12,10)

This is a poorly imported question, but if QR=12 and RS=19, that means R is in between Q and S. And two parts = a whole segment because of a certain rule. Meaning
QS = 31
