Answer:
<u>Alejandro went to 8 matinee shows and 4 evening shows.</u>
<u>Our system of equations:</u>
<u>x + y = 12</u>
<u>7x + 12y = 104</u>
Correct statement and question:
Alejandro loves to go to the movies. He goes both at night and during the day. The cost of a matinee is 7 dollars. The cost of an evening show is 12 dollars.
Alejandro went to see a total of 12 movies and spent $ 104. How many of each type of movie did he attend? Write a system of equations.

Step-by-step explanation:
Step 1:
Let x to represent the number of matinee shows Alejandro went to.
Let y to represent the number of evening shows Alejandro went to.
Now, let's write our system of equations:
x + y = 12
7x + 12y = 104
*********************
x = 12 - y
*********************
7 (12 - y) + 12y = 104
84 - 7y + 12y = 104
5y = 104 - 84
5y = 20
y = 20/5
<u>y = 4 ⇒ x = 12 - 4 = 8</u>
<u>Alejandro went to 8 matinee shows and 4 evening shows.</u>
Answer:
Volume of soccer ball = 5,572.45 Cm³ (Approx)
Step-by-step explanation:
Given:
Diameter of soccer ball = 22 Cm
Radius of soccer ball = 22 Cm / 2 = 11 Cm
Find:
Volume of soccer ball = ?
Computation:
![Volume\ of\ soccer\ ball = \frac{4}{3} \pi r^3\\\\ Volume\ of\ soccer\ ball = \frac{4}{3} \times\frac{22}{7} \times 11^3\\\\ Volume\ of\ soccer\ ball = 5,572.45332](https://tex.z-dn.net/?f=Volume%5C%20of%5C%20soccer%5C%20ball%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E3%5C%5C%5C%5C%20Volume%5C%20of%5C%20soccer%5C%20ball%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20%5Ctimes%5Cfrac%7B22%7D%7B7%7D%20%5Ctimes%2011%5E3%5C%5C%5C%5C%20Volume%5C%20of%5C%20soccer%5C%20ball%20%3D%205%2C572.45332)
Volume of soccer ball = 5,572.45 Cm³ (Approx)
Therefore, Soccer ball contain 5,572.5 Cm³ of air.
