The sum of n terms of a geometric sequence with first term "a" and common ratio "r" is given by
You have a=21, r=3, so the sum of 10 terms is
The appropriate choice is the 2nd one:
620,004
Find n first.
n+10= 40
Subtract 10.
n= 30
Plug in n.
30-25= 5
The answer is 5.
I hope this helps!

The answer to number 1 is 2/9 of her paycheck. The answer to number 2 is 3/5. Its square is 9/25 which is in between 1/3 and 1/2. It's reciprocal is 5/3 which is in between 1 and 2. It is also in simplest form.
Answer:5.5%
Step-by-step explanation:
The given table is the following:
Job Salary % of Employees
-------- ------------ ----------------------
Entry $30,000 60%
Expert $40,000 38%
CEO $125,000 2%
Let n = total number of employees.
Entry:
Number = 0.6n
Pay total = 0.6n*(30,000) = $18,000n
Expert:
Number = 0.38n
Pay total = 0.38n*(40,000) = $15,200n
CEO:
Number = 0.02n
Pay total = 0.02n*(125,000) = $2,500n
Total pay = 18,000n + 15,200n + 2,500n = $35,700n
Average salary = 35,700/n = $35,700
Answer: $35,700
