Below are the supply and demand equations for umbrellas in a certain market. in these equations, p represents price, d represent

timurjin [86]

The value of price (p) at a point of equilibrium is 13.4. Then the correct option is C.

<h3>What is the linear system?</h3>

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

The equation of the demand (D) and supply (S) is given below.

$\rm D = -\dfrac{4}{3}p +22\\\\S \ = 3p -36$

Where p is price.

At equilibrium, we have

D = S

Then

$\begin{aligned} \dfrac{4}{3}p +22 &= 3p -36\\\\3p + \dfrac{4}{3} p &= 36 + 22\\\\\dfrac{13}{3}p &= 58\\\\p &= 13.38 \approx 13.4 \end{aligned}$

More about the linear system link is given below.

Find the volume of a hemisphere that has a diameter of 48 inches and leave your answer in terms of pie

marin [14]

<u>Given</u>:

Given that the diameter of the hemisphere is 48 inches.

We need to determine the volume of the hemisphere.

<u>Radius:</u>

The radius of the hemisphere can be determined using the formula,

$r=\frac{d}{2}$

Substituting d = 48, we get;

$r=\frac{48}{2}$

$r=24$

Thus, the radius of the hemisphere is 24 inches.

<u>Volume of the hemisphere:</u>

The volume of the hemisphere can be determined using the formula,

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

Substituting r = 24, we get;

$V=\frac{2}{3} \pi (24)^3$

$V=\frac{2}{3} \pi (13824)$

$V=9216 \pi \ in^3$

Thus, the volume of the hemisphere is 9216π cubic inches.

Select the proper order from least to greatest for 2⁄3 , 7⁄6 , 1⁄8 , 9⁄10 . A. 1⁄8 , 2⁄3 , 9⁄10 , 7⁄6 . B. 7⁄6 , 9⁄10 , 2⁄3 , 1⁄

drek231 [11]

Let's look at the one that is less than 1/2.
This would be 1/8, so that should go first. We can eliminate B and c.
7/6 is more than 1, so we can eliminate d.
So, A would be the answer.

What is the most precise term for quadrilateral ABCD with vertices A(3,1) , B(4,5) , C(7,5) , D(7,2) answer choices; A. KITE B.

SOVA2 [1]

Answer:

Step-by-step explanation:

Given are the vertices of a quadrilateral.

WE have to find the name of the quadrilateral

WE have slope of AC = (5-1)/(7-3) = 1

and slope of BD = (2-5)/(7-4) = -1

Since m1m2 =-1 we get
