<h2>
5:6</h2>
Step-by-step explanation:
Given the total number of games played by the softball team = 18 games
Total games won = 15 games
Ratio of the softball team's wins to its total number of games played can be gotten by simply dividing the total games won by the total games played
Ratio = 

Expressing the ratio in its lowest term

Hence, the ratio of the softball team's wins to its total number of games played is 5:6
12. You do 8/10 times x/15, you multiply 15 times 8 which equals 120 then divide by 10
Step-by-step explanation:
The answer is

The number keeps subtractrating 1/3 when we go to the right.
Answer:
15 ft
Step-by-step explanation:
This is another classic case of Pythagoras theorem. To start with, let's assume that the length of the ladder we're looking for is x
We're told that the height of the building the ladder is leaning on is, x - 3
Also we're told that the distance at an adjacent from the ladder is 9 ft.
If we use Pythagoras theorem, we have
x² = (x - 3)² + 9²
x² = x² - 6x + 9 + 81
On rearranging, we have
x² - x² = -6x + 90
6x = 90
x = 90 / 6
x = 15 ft
Therefore, the length of the ladder is found to be 15 ft
