Well the centroid is the point that connects the median of a side with the opposite vertex. This means that each line is split i half. Notice that line HG is split in half by point K. that means that each of the segments that K splits is equal. so we know
HK = KG

and we know
HK = 3x
KG = x + 8

since
HK = KG then
3x = x + 8
2x = 8
x = 4

now we have x. we know that the each line that runs from a midpoint to a vertex is seperated by the centroid. the 2 line segments are a 2:1 ratio. so
2*JL = 1LG

we know
JL = x + 3

so
2 * (4 + 3) = LG
LG = 14

Quan is inviting 3 friends to a party. Each friend wants 8 cookies and each box has 6 cookies.How many boxes should Quan get?
Anastasy [175]
First, figure out how many total cookies you need. You do this by multiplying the number of friends times the number of cookies each friend will get.

8 x 3 = 24

Then, you take the number of cookies and divide it by the number in each box to find the number of boxes you need.

24/6 = 4

Quan should get 4 boxes.

What is 6.9 as a fraction or a mixed number
love history [14]
If you're looking for a fraction:
Think of it this way, the 9 is in the 10th place. The 6 is in front of the decimal. So, it's 69/10. The 10 takes the place of the 9, the "/" is the decimal moved to the right one space.

Or 

If you're looking for a mixed number:
You basically split the above fraction "69/10" up into two separate pieces. So, it's
6 9/10.

I certain brand of coffee comes into sizes a 10.5 ounce package cost $3.24 I 30.6 ounce package cost $9.88 find the unit price f
Fofino [41]
Unit price: divide each coffee's total cost by the total package weight.
First Coffee= $3.24 ÷ 10.5 oz= $0.3085 per oz= $0.31 per oz rounded

Second Coffee= $9.88 <span>÷ </span>30.6 oz= $0.3228 per oz
= $0.32 per oz rounded
 
ANSWER: The first coffee is a better buy at only $0.31 cents per ounce.  The second coffee has a higher price per ounce, so it is not a better buy.
Hope this helps!  :)
