The Alden Middle School girls' soccer team won 80% of its games this season.If the team won 12 games,how many games did it play? Solve the problem using at least two different methods.
Answers
g=12/0.8
Where 0.8 is 80% in fraction form (80/100), g is the number of games played and 12 is the games won.
0.8g=12
----- ---
0.8 0.8
g=15
g=12/0.8
g=15
They played a total of 15 games.
Check:
0.8(15)
=12
Final answer:
If the Alden Middle School girls' soccer team won 80% of games, i.e., 12 games, they played 15 games in total. This was determined using proportional relationship and direct calculations.
Explanation:
The subject of the student's question falls under Mathematics. Essentially, the student is asked to find the total number of soccer games Alden Middle School's girls team played given that they won 80% of these games, translating to 12 wins.
Method 1: Proportional Relationship If 12 games represent 80% wins, we can establish a proportional relationship: 12 (wins) / 80 (%) = x (total games) / 100 (%). Cross multiply to solve for x: 12*100=80*x and thus x = 15 games.
Method 2: Direct Calculation Knowing that 80% of games were won, divide the number of wins by this percentage to get the total games: 12 / 0.8 = 15 games. So the team played 15 games in total.

The distance CD rounded to the nearest tenth is approximately 17.3 units.
Here, we have to find the distance CD between points C(8, -3) and D(-9, -6), we can use the distance formula:
Distance CD = √[(x₂ - x₁)² + (y₂ - y₁)²]
where (x₁, y₁) are the coordinates of point C and (x₂, y₂) are the coordinates of point D.
Substitute the values:
Distance CD = √[(-9 - 8)² + (-6 - (-3))²]
Distance CD = √[(-17)² + (-3)²]
Distance CD = √[289 + 9]
Distance CD = √298
Now, round the result to the nearest tenth:
Distance CD ≈ 17.262
So, the distance CD rounded to the nearest tenth is approximately 17.3 units.
