4 minutes 34 seconds will takes to empty the tank, if the starts completely full and oil drained at a rate of 2.5 per minute.
Step-by-step explanation:
The given is,
Tank is shaped like a cylinder that is 3 ft long with a diameter of 2.2 ft.
Oil drained at a rate of 2.5 per minute.
Step:1
Time taken to dry the oil tank is,
T = ....................................(1)
Step:2
Volume of the oil is,
.................................................(2)
Where, r - Radius of Cylinder
r = 1.1 ft
From eqn (1),
V = ×
× 3
= 11.40398
Step:3
From equation (1)
=
= 4.56
= 4.56 minutes
T = 4 minutes 34 seconds
Result:
Time taken to dry the oil tank is 4 minutes 34 seconds, if a cylinder is 3 ft long with a diameter of 2.2 ft and oil is drained at a rate of 2.5ft^3 per minute.
<h2>Answer:</h2>
Step 1: We need to covert the current equation to <u><em>slope-intercept form*.</em></u>
<u><em></em></u><u><em></em></u>
Step 2: Now that we have our equation in slope-intercept form, we can determine the perpendicular slope of the line.
Our new slope is now <u><em>-5</em></u>.
*Slope-intercept form: <em>y = mx + b</em>
