At a party there is one bottle of coke for every 3 guests, one bottle of sprite for every 6 guests, and one bottle of lift for e

kodGreya [7K]

Answer:

72 guests

Step-by-step explanation:

We can add up the numbers of bottles per guest, then use that total to find the number of guests from the number of bottles.

<h3>Setup</h3>

Let g represent the number of guests at the party. Then there are ...

g/3 bottles of coke
g/6 bottles of sprite
g/4 bottles of lift

The total number of bottles is ...

g(1/3 +1/6 +1/4) = 54

<h3>Solution</h3>

Multiplying by the inverse of the coefficient of g, we find its value to be ...

g(4/12 +2/12 +3/12) = g(9/12) = 54

g = 54(12/9) = 72

There are 72 guests at the party.

A cone has a radius of 5 ft and a height of 15 ft. It is empty and is being filled with water at a constant rate of 15 15 ft 3 f

kvasek [131]

Answer:

$\frac{dr}{dt}=0.11062ft/sec$

Step-by-step explanation:

From the question we are told that:

Radius $r=5ft$

Height $H=15ft$

Rate $R=15ft/3sec =5ft/s$

Surface Radius $R_{surf}=2.2ft$

Generally the equation for Volume is mathematically given by

$V=\frac{1}{3}\pi*r^2h$

Since radius to height ratio gives

$\frac{r}{h}=\frac{5}{15}$

$\frac{r}{h}=\frac{1}{3}$

$h=3r$

Therefore

$V=\frac{1}{3}\pi*r^2(3r)$

$V=\pi r^3$

Generally the equation for Change of Volume is mathematically given by

$\frac{dv}{dt}=\pi \frac{d}{dt}(r^3)$

$\frac{dv}{dt}=\pi 3*r^2 \frac{dr}{dt}$

$\frac{dv}{dt}=\pi 3*(2.2)^2 \frac{dr}{dt}$

$\frac{dr}{dt}=\frac{5}{45.62}$

$\frac{dr}{dt}=0.11062ft/sec$
