Answer:

  A.  x = 2 and BQ = 27

Step-by-step explanation:

The key to this problem is the fact that the centroid divides the median into segments in the ratio 2 : 1.

  BM : MQ = 2 : 1

  BM = 2·MQ

  9x = 2(5x -1) . . . . . substitute the given expressions

  9x = 10x -2 . . . . . . eliminate parentheses

  0 = x -2 . . . . . . . . . subtract 9x

  2 = x . . . . . . . . . . . .add 2

BQ = BM + MQ = 9(2) +5(2) -1

BQ = 27

karen's hobby is chemistry. for one experiment she used 3 liters of water and 3 empty beakers she poured 0.7 L into the frist be
Burka [1]

By subtracting the water poured into the first two beakers from the available water we conclude that the water left for the third beaker is 0.9 liters.

<h3>How to find the water left for the third beaker</h3>

In this question we know that Karen has 3 liters of water and poured 0.7 liters into the <em>first</em> beaker, 1.4 liters into the <em>second</em> beaker and we can determine the water left for the <em>third</em> beaker by subtracted the water poured into the <em>first two</em> beakers from the available water. The available volume is:

V = 3 L - 0.7 L - 1.4 L

V = 0.9 L

By subtracting the water poured into the first two beakers from the available water we conclude that the water left for the third beaker is 0.9 liters.
