From inspecting the graph, you can identify the y-intercept and the slope of the line shown.
The y-intercept is 200 gallons.
The slope is
75-200
m = ------------- = -12.5 gallons/minute
10 - 0
Thus, y = 200 gallons - [12.5 gallons/minute ]t
To answer the 2nd question, let t = 12 minutes and calculate y(12).
To determine how long it wld take to empty the tank, set the above formula equal to zero and solve the resulting equation for t.
Write the equation of the line through (5,-4); m = 1
The question is incomplete
Answer:
Try this formula: length x width x height then you will find the answe. Hope this helps!
Times what by 20% ? If you can ask me the full question i would love to help!
