Answer:
90 games
Step-by-step explanation:
Given: Total number of team (n) = 10
Each team will play twice with each other.
We know that every team will play two game with each other except with itself, therefore each team will play 
⇒ Each team will play = 
∴ Each team will have 18 games with each other in the league.
Now, as there are total 10 teams and each team have 18 games each, however, we have to make sure that no team have more than two games with other team.
Example: 
Both the above game are same and it is a mistake to take two different game.
∴ Total number of games played by all team= 
⇒ Total games = 
∴ Rana have to schedule 90 games in the Volleyball league.
Let x be the fifth number
⇔
⇔ 23.3 + x = 34
⇔ x = 10.7

GIVE ME BRAINILEST
It's a computation. It would be 8!/3!(8-3)! If my memory serves me correctly.
Answer: The ball hits the ground at 5 s
Step-by-step explanation:
The question seems incomplete and there is not enough data. However, we can work with the following function to understand this problem:
(1)
Where 
models the height of the ball in meters and 
the time.
Now, let's find the time when the ball Sara kicked hits the ground (this is when 
):
(2)
Rearranging the equation:
(3)
Dividing both sides of the equation by 
:
(4)
This quadratic equation can be written in the form 
, and can be solved with the following formula:
(5)
Where:
Substituting the known values:
(6)
Solving we have the following result:
This means the ball hit the ground 5 seconds after it was kicked by Sara.
