Below are the demand and supply equations for overhead projectors in a certain market. In these equations, p represents price, D represents demand, and S represents supply. S = three-fourths p minus 28 D = negative 2 p 131 What is S at the point of equilibrium, to the nearest whole number? a. 12 b. 15 c. 58 d. 67.

Answers

Answer 1

For the equilibrium, the value of supply and the value of demand will be equal. Then the value of price (p) is 58.

What is the linear system?

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 demand and supply equations for overhead projectors in a certain market.

In these equations, p represents price, D represents demand, and S represents supply.

[tex]\rm S = \dfrac{3}{4}p - 28 \\\\D = -2 p + 131[/tex]

For the equilibrium, the value of supply and the value of demand will be equal. Then we have

[tex]\begin{aligned} \dfrac{3}{4}p - 28 &= -2 p + 131\\\\3p- 112 &= -8p + 524\\\\11p &= 636\\\\p &= 57.81818 \approx 58 \end{aligned}[/tex]

What is the length of the radius?

Answers

Answer:

h is 9 inches

Step-by-step explanation:

the volume of the cone is 2π[tex]r^{2}[/tex](h)(1/3)

just substitution, easy

75π=2π[tex]r^{2}[/tex](h)(1/3)

Solution:

Given:

[tex]\bullet \ \ \text{Volume of party hat} = 75\pi \text{ inches}^{3}[/tex]

[tex]\bullet \ \ \text{Radius of party hat:}\ 5 \ \text{inches}[/tex]

Recall that the formula to find the volume of a cone is πr²h/3. Now, let's use the formula to find the height.

[tex]\bullet \rightarrow \text{Volume of cone:} \ \dfrac{ \pi r^{2} h}{3}[/tex]

[tex]\bullet \rightarrow \text{Volume of party hat} =\dfrac{ \pi r^{2} h}{3} = 75\pi \text{ inches}^{3}[/tex]

[tex]\bullet \rightarrow \dfrac{ (\pi )( 5^{2})( h)}{3} = 75\pi \text{ inches}^{3}[/tex]

[tex]\bullet \rightarrow (\pi )( 5^{2})( h)} = 75\pi \times 3[/tex]

[tex]\bullet \rightarrow { (\pi )( 25)( h)}= 225\pi[/tex]

[tex]\bullet \rightarrow \dfrac{{ (\pi )( 25)( h)}}{25} = \dfrac{225\pi}{25}[/tex]

[tex]\bullet \rightarrow { (\pi )( h)}= 9\pi[/tex]

[tex]\bullet \rightarrow \dfrac{{ (\pi )( h)}}{\pi } =\dfrac{ 9\pi}{\pi }[/tex]

[tex]\bullet \rightarrow \boxed{\bold{h= 9 \ \text{inches}}}[/tex]

Thus, the height of the party hat is 9 inches.

7. a. dilate point c using center d and scale factor 3/4

b. dilate segment ab using center d and scale factor 1/2.

Answers

The dilations will give the relations:

C'D = (3/4)CD and A'B' = (1/2)AB

And a sketch of the graph can be seen at the end.

How to dilate C?

First, we want to dilate point C using D as the center of dilation with a scale factor = 3/4.

This only means that we will have the new point C', such that:

C'D = (3/4)*CD

Where CD is the distance between points C and D

b) Similarly, we will dilate the whole segment AB into the segment A'B', such that:

A'B' = (1/2)AB.

It is hard to give the exact graph when we don't know the coordinates of the points, but the graph should look something like the one you can see below.

A lamp is on sale, and its price is reduced from $80 to $50.

What is the percent of decrease?

Answers

Answer:

37.5 percent

Step-by-step explanation:

Finding percent is simple. You want to find percent of the price drop so you subtract 50 from 80 and get 30. Once you get 30 you divide by 80 (your original price). Once you do this you will get 0.375. Multiply this by 100 to get your percent.

I. As the review time decreases, the number of spelling mistakes increases.

II. As the review time increases, the number of spelling mistakes increases.

III. As the review time decreases, the number of spelling mistakes decreases.

(1,-2)(2,-4)

Direct variation

Hence

Option 1 and 4 are correct

Answer:

D)  I and IV

Step-by-step explanation:

The variable along the x-axis is the independent variable.

The variable along the y-axis is the dependent variable.

It would be fair to determine that the time spent reviewing a writing assignment is dependent upon the number of spelling mistakes, as the more mistakes an assignment has, the longer it should take to review, however we cannot say this for certain, therefore we cannot assign the dependent and independent variables.

If the scatter plot shows a negative linear relationship, then as the x-values increase, the y-values decrease.

Statements I and IV suggest a negative linear relationship only, depending on which variable is dependent and independent.
(FYI Statements II and III describe positive linear relationships)

Statement I

x-axis (independent variable) = number of spelling mistakes

y-axis (dependent variable) = review time

Statement IV

x-axis (independent variable) = review time

y-axis (dependent variable) = number of spelling mistakes

Therefore, as we cannot be sure which is the dependent variable and which is the independent variable, the solution is D.

You poured some 6% alcohol solution and some 8% alcohol solution into a mixing container. Now you have 600 grams of 7.4% alcohol solution. Write and solve a system of equations to find how many grams of 6% solution and how many grams of 8% solution you poured into the mixing container.
You mixed ___ grams of 6% solution with ____grams of 8% solution.

Answers

Answer:

180 grams of 6%420 grams of 8%

Step-by-step explanation:

Let s and e represent the grams of 6% and 8% solution, respectively. The given relations can be described by ...

  s + e = 600 . . . . . you have 600 grams of mixture

  0.06s +0.08e = 0.074(600) . . . . grams of alcohol in the mixture

__

The first equation can give an expression for s that substitutes nicely into the second equation:

  s = 600 -e

  0.06(600 -e) +0.08e = 0.074(600) . . . . substitute for s

  0.02e = 0.014(600) . . . . . . subtract 0.06(600)

  e = 420 . . . . . . . divide by 0.02

  s = 600 -420 = 180

You mixed 180 grams of 6% solution with 420 grams of 8% solution.

Answer: 180 grams of 6% solution with 420 grams of 8% solution.

Step-by-step explanation:

Let x and y be the weight (in grams) of 6% and 8% alcohol solution. Since the total weight is 600 grams, therefore,

[tex]$$\Rightarrow x+y=600 \ldots \text { (1) }[/tex]

Using the statement given, we can write the following equation:

[tex]\Rightarrow 6 x+8 y=(7.4)(600)\\ \Rightarrow 6 x+8 y=4440 \text {... (2) }[/tex]

Substitute the value of y from equation (1) into equation (2), we'll get:

[tex]\begin{gathered}\Rightarrow 6 x+8(600-x)=4440 \\\Rightarrow 6 x+4800-8 x=4440 \\\Rightarrow 2 x=360 \\\Rightarrow x=180\end{gathered}[/tex]

Therefore,

[tex]\Rightarrow y=600-180=420[/tex]

Therefore, you mixed 180 grams of 6% solution with 420 grams of 8% solution.

Problem 2

Answer: Approximately 73,280.62908 square feet

Explanation:

Calculate the area of the trapezoid. Ignore the small triangle for now.

A = h*(b1+b2)/2

A = 354*(266+158)/2

A = 75,048

Now calculate the area of the triangle we ignored earlier

Before we do this, we'll need to use the pythagorean theorem to find the missing horizontal piece

a^2 + b^2 = c^2

b = sqrt(c^2 - a^2)

b = sqrt(97^2 - 40^2)

b = 88.368546 which is approximate.

Now we can find the area of the small triangle

Area = base*height/2 = 88.368546*40/2 = 1,767.37092

This is to be subtracted from the area of the trapezoid we found earlier.

75,048 - 1,767.37092 = 73,280.62908

Round the result however you need to.
