Solve for N,

−2p + 6n = 5

Answers

Answer:

[tex]n=\frac{1}{3}p+\frac{5}{6}[/tex]

Step-by-step explanation:

In this question, you are solving for n.

Solve:

−2p + 6n = 5

We have to get "n" by itself, so add 2p to both sides.

6n = 2p + 5

Since the variable "n" has a number next to it, we have to get rid of that number in order to get our answer.

To do so, we would divide both sides by 6.

[tex]n=\frac{2}{6}p+\frac{5}{6}[/tex]

Simplify the equation further.

[tex]n=\frac{1}{3}p+\frac{5}{6}[/tex]

Find the missing angle.

Answers

Answer:

[tex]m\angle XYV=135^{\circ}[/tex]

Step-by-step explanation:

Notice that [tex]m\angle XYV=m\angle XYW+m\angle VYW[/tex].

The diagram already marks [tex]m\angle VYW=80^{\circ}[/tex], so we just need to find [tex]m\angle XYW[/tex].

[tex]\angle TYU[/tex] and [tex]\angle XYW[/tex] are vertical angles, which means they are equal in measure.

Therefore,

[tex]m\angle TYU=m\angle XYW=6x+7[/tex]

Since there are [tex]180^{\circ}[/tex] on each side of a line, we have the following equation:

[tex]m\angle XYW+m\angle VYW+m\angle UYV=180^{\circ},\\6x+7+13+4x+80=180,\\10x+20=100,\\10x=80,\\x=8[/tex].

Plugging in [tex]x=8[/tex], we have:

[tex]m\angle XYW=6(8)+7=55^{\circ}[/tex].

Therefore,

[tex]m\angle XYV=55^{\circ}+80^{\circ},\\m\angle XYV=\fbox{$135^{\circ}$}[/tex].

Answer:

[tex]m\angle1=75^{\circ}[/tex]

Step-by-step explanation:

Solution 1:

[tex]m\angle1[/tex] is formed by a point that is on the circle. The angle encompasses an arc of [tex]150^{\circ}[/tex] and thus the measure of the angle formed is [tex]\frac{150}{2}=\fbox{$75^{\circ}$}[/tex].

Solution 2:

Since [tex]\angle 1[/tex] is adjacent to a line and encompasses an arc, we can set up the following proportion:

[tex]\frac{150}{360}=\frac{m\angle 1}{180}[/tex]

Solving, we get [tex]m\angle 1=\fbox{$75^{\circ}$}[/tex].

A 12 foot ladder leans against a building at a 75 degree with the ground. Which equation below can be used to find how high the ladder reaches up the side of the building

Answers

Answer:

[tex] \huge\boxed{\sin(75°) = \frac{x}{12}} [/tex]

(B) is the right answer.

sin(¢)=perpendicular/hypotenuse

A 12 foot ladder leans against a building at a 75 degree with the ground. Therefore ladder reaches approximately 11.59 feet up the side of the building.

Trigonometry, specifically the sine function, may determine how high the ladder is up the building. A right triangle's sine is the ratio of the opposing side's length to the hypotenuse. The ladder is the hypotenuse of the right triangle, and we want to find the ladder's height up the building's side.

Let's call the height h. The given information is that the ladder (hypotenuse) is 12 feet, and the angle between the ladder and the ground is 75 degrees.

Using the sine function:

sin(75 degrees) = opposite / hypotenuse

sin(75 degrees) = h / 12

Now, we can solve for h:

h = 12 × sin(75 degrees)

Using a calculator:

h = 12 × 0.96592582628 = 11.59 feet

So, the ladder reaches approximately 11.59 feet up the side of the building.

determine the promotional price of each item at each store

Answers

Answer:

Step-by-step explanation:

Original price of the music box = $80

Price after 20% discount = Original price - discount

                                         = 80 - 20% of 80

                                         = 80 - [tex](\frac{20}{100}\times 80)[/tex]

                                         = 80 - 16

                                         = $64

Price after 40% discount = 80 - 40% of $80

                                         = 80 - 32

                                         = $48

Original price of A faux Ming vase = $60

Price after 20% discount = Original price - discount

                                         = 60 - 20% of $60

                                         = 60 - 12                                    

                                         = $48

Price after 40% discount = Original price - discount

                                         = 60 - 40% of 60

                                         = 60 - 24

                                         = $36

Answers

Answer:

The gradient of [tex]y = x^{5}[/tex] is [tex]\frac{dy}{dx} = 5\cdot x^{4}[/tex].

Step-by-step explanation:

Geometrically speaking, the gradient of a curve is the slope of the tangent line at a given point of the curve. From perspective of Differential Calculus, the gradient is the first derivative of the curve. Let [tex]y = x^{5}[/tex], then the gradient of the curve is:

[tex]\frac{dy}{dx} = 5\cdot x^{4}[/tex] (1)

The gradient of [tex]y = x^{5}[/tex] is [tex]\frac{dy}{dx} = 5\cdot x^{4}[/tex].

How Did Transportation Affect Westward Expansion? Metered music or sounds have a consistent beat and/or tempo. true or false While not formally one of the national political institutions, political parties today are nonetheless major players in both national and state politics. They have long provided what may be considered quasi-governmental services, including candidate recruitment, the operation of political campaigns, and the supervision of the voting process. As with the federal bureaucracy, political parties are important extra-constitutional political institutions that have been essentially grafted onto our separation of powers system. The ambiguity surrounding the proper institutional role that parties should conceptually play in American politics has posed vexing problems for the courts in balancing party independence with government supervision. In order to ascertain the role that political parties should play within our political system, it is useful to see them as informal parts of the larger system of separation of powers. If parties are seen as part of this larger system, then it follows that they are entitled to a certain amount of judicial protection to ensure their integrity and independence. Under this interpretation, the courts should bear some responsibility for preserving the separateness of political parties in the same way as the judiciary ensures that the powers of the formal branches of the government do not unduly infringe upon one another. If parties are seen as performing some governmental functions, then it follows that they should be entitled to some independence in the conduct of these functions. If parties are to check government power, then some of their activities must lie beyond direct government control.Robert C.
