Gravel is being dumped from a conveyor belt at a rate of 15 ft3/min, and its coarseness is such that it forms a pile in the shap

gayaneshka [121]

Answer:

0.13 ft/min

Step-by-step explanation:

We are given that

$\frac{dV}{dt}=15ft^3/min$

We have to find the increasing rate of change of height of pile when the pile is 12 ft high.

Let d be the diameter of pile

Height of pile=h

d=h

Radius of pile,r= $\frac{d}{2}=\frac{h}{2}$

Volume of pile= $\frac{1}{3}\pi r^2 h=\frac{1}{12}\pi h^3$

$\frac{dV}{dt}=\frac{1}{4}\pi h^2\frac{dh}{dt}$

h=12 ft

Substitute the values

$15=\frac{1}{4}\pi(12)^2\frac{dh}{dt}$

$\frac{dh}{dt}=\frac{15\times 4}{\pi(12)^2}$

$\frac{dh}{dt}=0.13ft/min$

The width-to-height ratio of a certain computer monitor

Mnenie [13.5K]

<h2>24 inches</h2>

Step-by-step explanation:

It is given that $\frac{\textbf{width of computer monitor}}{\textbf{height of computer monitor}}=\frac{16}{9}$

It is given that $\text{height of computer monitor}=13.5$

$\text{width of computer monitor} =\text{height of computer monitor}\times \frac{16}{9}$

$\text{width of computer monitor}=13.5\times \frac{16}{9} =\frac{216}{9} =24$

Hence the required width in inches is 24.
