Area of a rectangle: length times width (L•W).
Convert 2 feet into inches: 2•12=24.
Put the length and width into the formula: 6in•24in=144in.
Simplify: 144in=12ft.
Area=12 ft :)
Answer: John Hancock Center is faster
Step-by-step explanation:
If the equation is y=30x and x represents seconds then multiply 30 and 60 to get the amount of feet travelled per minute which is 1800. If 1800>1400 then John Hancock Center has a faster elevator rate.
Answer:
Therefore,the level of paint is rising when the bucket starts to overflow at a rate cm per minute.
Step-by-step explanation:
Given that, at a rate 4 cm³ per minute,a cylinder bucket is being filled with paint
It means the change of volume of paint in the cylinder is 4 cm³ per minutes.
i.e cm³ per minutes.
The radius of the cylinder is 20 cm which is constant with respect to time.
But the level of paint is rising with respect to time.
Let the level of paint be h at a time t.
The volume of the paint at a time t is
Differentiating with respect to t
Now putting the value of
To find the rate of the level of paint is rising when the bucket starts to overflow i.e at the instant h= 70 cm.
Therefore, the level of paint is rising when the bucket starts to overflow at a rate cm per minute.
Usually, a square... But it can be a rectangle or a trapezoid.... Basically, all shapes with 4 sides, vertices, and labeled points of "A,B,C,D"
