Los Angeles location the book is selling is less expensive than in Europe.

In Europe the book costs 19 euros but we know 1euro = $1.25 
so 19 euro = 19 * $1.25 = $23.75
In Los Angeles the book only costs $22.50, $1.25 less than in Europe.

Fond the area of the shaded sector of circle C to the nearest tenth
Lesechka [4]

Solution

Step 1

Write an expression for the area of sector

Area\text{ (A) = }\frac{\theta}{360}\times\pi\times r^2

Where

θ = 52°

π = 3.14

r = 8cm

Step 2

Find the area of the sector after substitution of values into the formula above.

\begin{gathered} A\text{ =}\frac{52}{360}\times3.14\times8^2 \\ A=29.028cm^2 \end{gathered}

To the nearest tenth the area of the shaded sector of circle C = 29.0cm²

The admission at the movies is $5 for children and $10 for adults. The total amount collected was
sesenic [268]

Answer:

Number of children, x= 400

Number of adults, y = 100

Step-by-step explanation:

Let the number of children be x

Let the number of  adults be y

Given : Total number of people,  x + y = 500  --------(1)

           Total amount collected, 5x + 10y = 3000  ---------(2)

(1) => y = 500 - x

Substitute y in (2) : 5x + 10(500 - x) = 3000

                             5x + 5000 - 10x = 3000

                                -5x = 3000 - 5000

                                 -5x = -2000

                                    x = 400

Substitute x in (1) : 400 + y = 500

                                      y = 500 - 400

                                      y = 100
