Answer:
Only 4 is the right answer. The rest all are false.
Answer: 2.5 hours or 2 hr and 30 min
Step-by-step explanation:
We can set up an equation to find how many hours you can park.
2.5+4x=12.5
The 2.5 comes from the base fee. The 4x is the hourly rate, where x is hours. The 12.5 is the total amount of money you have.
Since we have our equation, we can solve for x.
4x=10
x=2.5
You can park for 2.5 hours, or 2 hours and 30 min.
Answer:
40
Step-by-step explanation:
Multiples of 8:
8, 16, 24, 32, 40, 48, 56
Multiples of 10:
10, 20, 30, 40, 50, 60
Multiples of 20:
20, 40, 60, 80
1 20
If you know the formula use it for every single one
Given:
The sequence is:
To find:
The explicit formula for the given sequence and then find the 16th term.
Solution:
We have,
The ratio between two consecutive terms are:
The given sequence has a common ratio. So, the given sequence is a geometric sequence with first term 6 and common ratio 
.
The explicit formula of a geometric sequence is:
Where, a is the first term and r is the common ratio.
Putting 
in the above formula, we get
We need to find the 16th term. So, put 
in the above formula.
Therefore, the explicit formula for the given sequence is and 16th term of the given sequence is 
.
