Pachacha [2.7K]

Answer:

51 minutes

Step-by-step explanation:

We have the ratio ...

show minutes : commercial minutes = 15 : 2

Multiplying by 3 gives ...

show minutes : commercial minutes = 45 : 6

The total of show minutes and commercial minutes is 45+6 = 51 minutes.

inna [77]

Answer: A) 480

Step-by-step explanation:

x=20 substitute in the two equations

48(20)+37

24(20)+37

since the question said fewer , then you should subtract

48(20)+37 - 24(20)+37 = (960+37) - (480+37)

=923 - 443= 480

A microwaveable cup-of-soup package needs to be constructed in the shape of cylinder to hold 700 cubic centimeters of soup. The

Korvikt [17]

Answer:

r = 3.43 cm

h=18.94 cm

Step-by-step explanation:

The volume of the cylinder is:

$V=\pi r^{2}h=700cm^{3}$

where r is the radius of the circular base and h is the height of the cylinder.

The cost of the side of the cylinder is:

$(0.02)2\pi rh$

The cost ot the bottom of the container is:

$(0.02)\pi r^{2}$

The cost ot the top of the container is:

$(0.09)\pi r^{2}$

Then, the total cost of the container is:

$C=(0.02)2\pi rh+(0.02)\pi r^{2}+(0.09)\pi r^{2} \\C=\pi r(0.04h+0.02r+0.09r)\\C=\pi r(0.04h+0.11r)$

From the volume, you could solve for one variable and substituting in the cost equation:

$h=\frac{700}{\pi r^{2}}\\C=\pi r(0.04(\frac{700}{\pi r^{2}})+0.11r)$

In order to minimize this fuction you need to calculate the derivative respect to r:

$\frac{dC}{dr} =\frac{dC}{dr}[\frac{28}{r}+0.11\pi r^{2}]\\\frac{dC}{dr} =-\frac{28}{r^{2} }+0.22\pi r$

The critical points of the function are obtained when dC/dr=0:

$-\frac{28}{r^{2}}+0.22\pi r=0\\0.22\pi r=\frac{28}{r^{2} }\\r^{3}= \frac{28}{0.22\pi } \\r=3.43 cm$

To evaluate if this critical point is a minimum, you should get the second derivative:

$\frac{d^{2} C}{dr^{2} } =\frac{28}{r^{3} }+0.22\pi \\$

For the critical point r = 3.43 cm, the second derivative is positive, which means that the critical point is a minimum.

Then, the dimensions for the package tht will minimize product cost are:

r = 3.43 cm

$h=\frac{700}{\pi r^{2} } =18.94cm$
