Rain is flowing into two containers at
9966 [12]

Given:

Volume of water in each container.

To find:

Difference in the rate of change.

Solution:

Take any two points on container 1.

Let the points are (10, 2) and (20, 4).

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{4-2}{20-10}

$m=\frac{2}{10}

$m=\frac{1}{5}

Rate of change for container 1 is \frac{1}{5}.

Take any two points on container 2.

Let the points are (5, 2) and (10, 4).

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{4-2}{10-5}

$m=\frac{2}{5}

Rate of change for container 2 is \frac{2}{5}.

Difference = \frac{2}{5}-\frac{1}{5}

                  $=\frac{1}{5}

The difference in the rate of change between the two containers is \frac{1}{5} gallon per minute.

The perimeter of a rectangular garden is 100 feet​ (ft). the area of the rectangular garden area is 600 ft2. find the length and
svlad2 [7]
Let the length be x and the width be y:
Area=x*y=600
thus
x=600/y

Perimeter=2(L+W)
100=2(x+y)
substituting the value of x we obtain:
100=2(600/y+y)
solving for y we shall have:
50=600/y+y
50y=600+y^2
thus
y^2-50y+600=0
solving the quadratic we obtain:
y=20 or y=30
thus the length=30 ft and the width=20 ft

Water flows through a pipe at a rate of 91 fluid ounces every 2.5 weeks. Express this rate of flow in cups per hour. Round your
Ulleksa [173]

Answer:

Step-by-step explanation:

First, we convert:

  • ounces to cups
  • weeks to hours

Result of conversion:

  • 91 fluid ounces = 11.375 cups  (1 cup = 8 ounces)
  • 2.5 weeks = 420 hours (1 week = 168 hours)

To get the rate, we must divide the number of cups by number of hours

  11.375 cups / 420 hours = 0.027 cups per hour = 0.03 cups per hour (approximated)

Hope that helps!
