What is the radius of a circle with an area of 78.5 cubic inches? Use 3.14 for pi. Enter your answer in the box.
UkoKoshka [18]

\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ A=78.5 \end{cases}\implies 78.5=\pi r^2\implies \cfrac{78.5}{\pi }=r^2 \\\\\\ \sqrt{\cfrac{78.5}{\pi }}=r\implies 4.9987\approx r

natita [175]

Answer:

x = 52.00

Step-by-step explanation:

Given

Demand: p = 0.16x + 16

Supply: p -0.09x + 29

Required

Determine the equilibrium price

This is determined when Demand = Supply

So:

0.16x + 16 = -0.09x + 29

Collect Like Terms

0.16x + 0.09x = 29 - 16

0.25x = 13

Solve for x

x = 13/0.25

x = 52.00

<em>Hence; The equilibrium price is when x = 52.00</em>

Find the measure of the segment indicated.
julsineya [31]
Answer is QM = 18

You can find the length of QM by using Pythagorean theorem. See the attachment.

It is a quadrilateral with 4 equal congruent sides.

If SP = 30, so do the other 3 sides indicated by the tick marks on all 4 sides.

We will call side RQ = the hypotenuse
or side “c” = 30
We know RM is leg “b” = 24
Side “a” is our unknown QM

Our formula is
a^2 + b^2 = c^2

a^2 + 24^2 = 30^2

a^2 + 576 = 900

a^2 = 900 - 576

a^2 = 324

Take square root of both sides to solve a

a = 18

QM = 18
