Here is the solution to the given problem above.
Given the the amount of water in a pool is decreasing 5/8 gallon every hour.
And what would be the change in the number of gallons after 3/4 hour. So what we are going to do is just to multiply 5/8 by 3/4. And the result would be 15/32. The total change in the number of gallons of water in the pool after 3/4 hour would be 15/32 gallons.

Find the centroid of the triangle with these vertices: P (-1,7), Q (9,5), and R (4,3).
Mumz [18]

Answer:

The coordinates of the centroid are:

O\:=\:\left(4,\:5\right)\:\:

The diagram is also attached below.

Step-by-step explanation:

Given the vertices

  • P (-1, 7)
  • Q (9, 5)
  • R (4, 3)

We know that the intersection of medians brings the centroid of the triangle.

The centroid of a triangle is given by

O\:=\:\left(\frac{P_x+Q_x+R_x}{3},\:\frac{P_y+Q_y+R_y}{3}\:\right)

In this example,

P_x=-1,\:P_y=7

Qx=9,\:Q_y=5

Rx=4,\:R_y=3

substituting in the formula

O\:=\:\left(\frac{-1+9+4}{3},\:\frac{7+5+3}{3}\:\right)\:\:

O\:=\:\left(\frac{12}{3},\:\frac{15}{3}\:\right)\:\:

O\:=\:\left(4,\:5\right)\:\:

Therefore, the coordinates of the centroid are:

O\:=\:\left(4,\:5\right)\:\:

The diagram is also attached below.
