A local children's theater sold tickets for their evening show at $5 for children and $15 for adults. For their afternoon matine
Oksanka [162]

The solution of the system of linear equations is x = 50, y = 20.

The point of intersection represents the solution found analytically and represents the scenario in which the <em>same</em> quantity of adults and children assisted to both shows.

<h2>Procedure - Determination of the number of people assisting to a movie</h2><h2 /><h3>Construction of the system of equations</h3><h3 />

In this question we need to construct a linear function for the total of people that assisted to the evening show and for the total of people that assisted to the afternoon matinee. The system of equations is described below:

Evening show

5\cdot x + 15\cdot y = 550 (1)

Afternoon matinee

2\cdot x + 5\cdot y = 200 (2)

Where:

  • x - Number of children that assisted.
  • y - Number of adults that assisted.

<h3>Resolution of the system of equations and analysis of the results</h3><h3 />

By algebraic means we find the following result associated with the system of equations:

x = 50, y = 20 \blacksquare

The graphic representation of this system is described in the image attached below.

The point of intersection represents the solution found analytically and represents the scenario in which the <em>same</em> quantity of adults and children assisted to both shows. \blacksquare

The cost of a DVD box set increase from 30 to 35 a student says that this represent a 5% increase in the price explain the stude
tamaranim1 [39]
So it went from 30 to 35, or 5 bucks, if we take 30 to be the 100%, what is 5 off of it in percentage?

\bf \begin{array}{ccll}&#10;amount&\%\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;30&100\\&#10;5&p&#10;\end{array}\implies \cfrac{30}{5}=\cfrac{100}{p}\implies p=\cfrac{5\cdot 100}{30}

Solve the triangle If b=16 and B=55
Romashka-Z-Leto [24]

Answer:

Just use the law of Sine

To find A degree's & side a as

A degrees equals 180 - 90 - 55 = 35

Sin(35°) / a = Sin(55°) / 16

16 * [sin(35°)] = a * [sin(55°)]
