Step-by-step explanation:
Answer:
8.89 gallons per hour
Step-by-step explanation:
In order to find the rate of change, you need to find the slope of the graph.
To find the slope, you use equation (y2 - y1 ) / (x2 - x1)
The given coordinates are:
(0 hours, 0 gallons)
(4.5 hours, 40 gallons)
Next, plug in the x and y values into the slope equation:
y2 = 40 gallons
y1 = 0 gallons
x2 = 4.5 hours
x1 = 0 hours
Slope = (40 - 0) / (4.5 - 0) = 40 gallons / 4.5 hours = 8.888889 gallons per hour
round to 8.89
Answer:
total surface area = 936 in²
Step-by-step explanation:
total surface area = surface area of the pyramid + surface area of the cube
1. surface area of the pyramid = 4 * area of lateral triangle side
area of lateral triangle side = 12 * 9 /
area of lateral triangle side = 54 in²
2. surface area of the pyramid = 4 * 54
surface area of the pyramid = 216 in²
3. surface area of the cube = 5 * (12 x 12)
-surface area of the cube = 720 in²
therefore, the total surface area = 216 in² + 720 in²
total surface area = 936 in²
