If 6 people want to share a 30 pound bag of beans equally by weight how many pounds of beans should each person get? Between wha

sertanlavr [38]

Answer:

The 6 people would each get 5lb. of beans. 5 lies between 4 and 6.

Step-by-step explanation:

To get the answer to this problem, all you have to do is divide the total pounds of beans by how many people there are. 30 ÷ 6= 5, so each person would get 5 pounds. Since 5 comes between 4 & 6, you can use that as your answer.

Water flows into a right cylindrical shaped swimming pool with a circular base at a rate of 4 m33/min. The radius of the base is

Sloan [31]

Answer:

The water level is rising at a rate of approximately 0.1415 meters per minute.

Step-by-step explanation:

Water is flowing into a right cylindrical-shaped swimming pool at a rate of 4 cubic meters per minute. The radius of the base is 3 meters.

And we want to determine the rate at which the water level of the pool is rising.

Recall that the volume of a cylinder is given by:

$\displaystyle V = \pi r^ 2h$

Since the radius is a constant 3 meters:

$\displaystyle V = 9\pi h$

Water is flowing at a rate of 4 cubic meters per minute. In other words, dV/dt = 4 m³ / min.

Take the derivative of both sides with respect to <em>t: </em>

<em /> $\displaystyle \frac{d}{dt}\left[ V\right] = \frac{d}{dt}\left[ 9\pi h\right]$ <em />

Implicitly differentiate:

$\displaystyle \frac{dV}{dt} = 9\pi \frac{dh}{dt}$

The rate at which the water level is rising is represented by dh/dt. Substitute and solve:

$\displaystyle \left(4 \right) = 9\pi \frac{dh}{dt}$

Therefore:

$\displaystyle \frac{dh}{dt} = \frac{4}{9\pi} \approx 0.1415\text{ m/min}$

In conclusion, the water level is rising at a rate of approximately 0.1415 meters per minute.
