Mark these points on the graph to form a right angled triangle.
Angle Y will be 90 degrees
Answer: 330
Step-by-step explanation:
You would just have to isolate for x
so it would simply become
-1.56/-7.8
= 0.2
So 80% of 15 games won equal 12 games won and 3 lost. This is because 15/10 = 1.5 and 1.5 x 8 =12.
For 30, you do the exact same thing but with 90% instead. 30/10 = 3. 3 x 9 = 27.
So they need to have won 27 games to get a 90% winning percentage out of 30 games.
But since the question asks how many MORE games they need to play, it'll be 27-12 = 15.
So they need to win 15 more games to get a 90% winning percentage
