Answer:
4920
7084800
2585952000
Step-by-step explanation:
82 chirps = 1 minute
We have 60 minutes in one hour, so 82 x 60 =4920 chirps in one hour
In 24 hours we have 60x24 = 1440 minutes and in one minutes we have 4920 chirps,
Therefore 4920 x 1440 mins =7084800 chirps in one day .
There are 365 days in a year and in one day the cricket chirps 7084800, so 365 days x 7084800 = 258595200 chirps in a year
Answer:
The equation is 
Step-by-step explanation:
First off, we know r is going to be subtracted from 6 somewhere in the expression since the problem says "decreasing by r miles per hour."
If we want to see how long it would take him to jog 8 miles up to the mountain road we would have to take 8 and divide it by 6 - r.
Therefore, the equation is

Answer: 9/14 of a pound each day.
Step-by-step explanation:
We can convert the mixed fraction into an improper fraction:
4 1/2 → 9/2
Now we divide by 7, since there are 7 days in a week:
9/2 ÷ 7
When we divide, by a number, it can be placed in the denominator:
9/2*7 = 9/14
There's no other way to simplify it, so that's our final answer.
Given:
The geometric sequence is:

To find:
The 9th term of the given geometric sequence.
Solution:
We have,

Here, the first term is:

The common ratio is:




The nth term of a geometric sequence is:

Where, a is the first term and r is the common ratio.
Substitute
to find the 9th term.




Therefore, the 9th term of the given geometric sequence is 5103.
