#7 is 6/8 im not sure about #6
Using a geometric sequence, it is found that after 3 rounds, 8 teams are left.
In a geometric series, the quotient between consecutive terms is always the same, and it is called common ratio q.
The general equation of a geometric series is given by:
In which is the first term.
In this problem:
- 64 teams were invited, thus .
- After each round, half the teams are eliminated, thus .
The <u>number of teams after 3 rounds</u> is the 4th term of sequence, as the first is the initial number(0 rounds), thus:
After 3 rounds, 8 teams are left.

Answer:
Step-by-step explanation:
Let the distance be and the time be .
It was given that the distance, , varies directly as the square of the time , we write the proportional relation,
.
, where is the constant of variation.
It was also given that, , when .
Now the equation of variation becomes;
When, ,
The object will travel 301865 feet in 55 seconds.
Find 110% of 40
we already see the 100, so it's 40 + x
so 10% of 40 is 40*.10 which is 4
so it's 40+4
44 is 110% of 40.
Another way of finding this is just multiplying 40*1.10 on a calculator or by hand.
