10 because 8 squares plus 6 squared equals 100 and the root of 100 is ten
3y ≥ 2x + 5
3 3
y ≥ ²/₃x + 1²/₃
3 ≥ ²/₃(2) + 1²/₃
3 ≥ 1¹/₃ + 1²/₃
3 ≥ 3
The answer is D.
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.
Answer:
142 watermelon
Step-by-step explanation:
10/71 = 20 / w
w = 20(71/10) = 142
