a rectangular pyramid has a volume of 190 cubic centimeters. Find two possible sets of measurements for the base area and height

DerKrebs [107]

<h3>One possible set for the base area and height of the pyramid is 570 cm and 1 cm respectively</h3><h3>Other possible set for the base area and height of the pyramid is 285 cm and 2 cm respectively</h3>

Solution:

The volume of rectangular pyramid is given as:

$Volume = \frac{1}{3} \times base\ area \times height$

Given that,

Rectangular pyramid has a volume of 190 cubic centimeters

$190= \frac{1}{3} \times base\ area \times height$

Substitute, base area = 570 and height = 1

Then we get,

$190 = \frac{1}{3} \times 570 \times 1\\\\190 = 190$

Thus one possible set for the base area and height of the pyramid is 570 cm and 1 cm respectively

Substitute, base area = 285 and height = 2

$190 = \frac{1}{3} \times 285 \times 2\\\\190 = \frac{1}{3} \times 570\\\\190 = 190$

Thus other possible set for the base area and height of the pyramid is 285 cm and 2 cm respectively

If the marginal revenue (in dollars per unit) for a month is given by MR = −0.5x + 400, what is the total revenue from the produ

Vesna [10]

Given:

Marginal revenue (in dollars per unit) for a month is

$MR=-0.5x+400$

To find:

The total revenue from the production and sale of 30 units.

Solution:

We know that, total revenue is integration of marginal revenue with respect to quantity.

$TR=\int MR dx$

$TR=\int (-0.5x+400) dx$

$TR=-0.5\int x dx+400\int 1 dx$

$TR=-0.5\times \dfrac{x^2}{2}+400x$

Now, substitute x=30 in the equation of Total Revenue (TR).

$TR=-0.5\times \dfrac{30^2}{2}+400(30)$

$TR=-0.5\times \dfrac{900}{2}+12000$

$TR=-225+12000$

$TR=11775$

Therefore, the total revenue from the production and sale of 30 units is $11,775.
