The image is really unclear but I will assume that the number of teams given = 66
and the formula is
plug in the number of teams
multiply both sides by two
subtract 132 from both sides and factor
t = 12
3 odd integers have a property that they average up to the middle large one. Let's say we have 3, 5, and 7. 3 is 2 less than 5 and 7 is 2 more than 5. so when you add them it equals 2 times 5.
After we know that, the sum of 3 odd integers is just 3 times the middle number. ex. 3+5+7 = 3 times 5 = 15
Then we know the some number times three = 225. we find out that the middle number is 75, so the other two are 73 and 77
Answer:
Step-by-step explanation:
The weighted average of the student's scores is ...

Answer:
Diameter of the circle is 
units
Step-by-step explanation:
It is given that the vertices of the square fall on the circle.
So, the diagonal of the square is the diameter of the circle.
Also, the diagonal and the two sides of the square form a right angled triangle.
By Pythogoras theorem,
= 
= 
units
Hence, the diameter of the circle is units
