Answer:
The nth term is 109-9n
Step-by-step explanation:
Here, we want to find the nth term of the given arithmetic sequence
Mathematically, we have the nth term as;
Tn = a + (n-1)d
where a is the first term which is 100 in this case
d is the common difference which is the value obtained by subtracting the preceding term from the succeeding term; it is constant throughout the sequence
The value here is thus;
82-91 = 91-100 = -9
Substituting these values
Tn = 100 + (n-1)-9
Tn = 100 -9n + 9
Tn = 100 + 9 - 9n
Tn = 109-9n
Answer:
∠ULE = 60°
Step-by-step explanation:
The exterior angle marked 109° is the sum of the remote interior angles marked 49° and x.
109° = 49° + ∠ULE
∠ULE = 109° -49°
∠ULE = 60°
Calculate the number of people who sat on the visitors' side:
8644
-5100
--------
3544
Now divide 3544 people by 8 sections:
3544 people
----------------- = 443 per section.
