Answers

Answer 1
Answer:

There were 431 reserve seat tickets and 1356 general admission tickets sold.

What is Cost Function?

A cost function is a mathematical formula used to used to chart how production expenses will change at different output levels. In other words, it estimates the total cost of production given a specific quantity produced.

Let 'x' represent the number of reserve seats that were sold,

then '1787-x' represents the number of general admission tickets sold

we then have the following cost equation:

5792 = 4x + 3(1787-x)

solving for 'x' we have:

x = 431

1787-431 = 1356

Thus, there were 431 reserve seat tickets and 1356 general admission tickets sold.

Answer 2
Answer: Equation for tickets sold:                        Equation for money made:
x+y=1787                                              4x+3y=5792
Solve for x using substitution:
x=1787-y
Plug it into the other equation to find the value of y:
4(1787-y)+3y=5792
7148-4y+3y=5792
-y=-1356
y=1356
Now plug y back into any equation:
x+1356=1787
x=431

1356 general admission tickets were sold, and 431 reserved seats were sold.

The hexagon is split equally, making all the triangles there equilateral, and their angles equal all 60 degrees. That automatically makes angle one and three 60 degrees. For angle two, there is a line, splitting the triangle in half. There are two ways to consider this:

1. Think about the 30°, 60°, 90° special triangles.

or 

2. divide 60° by 2, and having 30° in return.

PLEASE HELP ASAP!!! I NEED CORRECT ANSWERS ONLY PLEASE!!!Find PR.

Write your answer as an integer or as a decimal rounded to the nearest tenth.

PR =

Answers

The length of PR is 4.4 units.

Explanation:

It is given that the length of the hypotenuse is 10 units.

Also, the angle of R is 64°

To find the length of PR, we shall use the cosine formula,

\cos \theta=(a d j)/(h y p)

Here,  \theta=64, adj = PR and hyp = 10

Substituting these values in the formula, we get,

\cos 64=(P R)/(10)

Multiplying both sides by 10, we get,

10*\cos 64={P R}

Substituting the value for cos 64, we get,

10*0.438={P R}

Multiplying, we have,

4.38=PR

Rounding off, we get,

PR=4.4

Thus, the length of PR is 4.4 units.
