What ages, in years, does the interval of 80-89 months represent

1 answer:

3 0

Well, there are 12 months in a year, so divide 80 and 89 by 12, which gives you 6 years and a remainder of 8 months, and 7 years with a remainder of 5 months. So your answer is 6 years 8 months- 7 years 5 months.

bezimeni [28]

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
