Answers
Answer:
(a) The average rainfall per month during these three months(June, July and August) = 50 cm
(b) The total rainfall during the entire year 2014 = 276 cm
(c) The average rainfall per month during the other 9 months = 75.33 cm
Step-by-step explanation:
Given data;
The average rainfall per month in the year 2014 = 23 cm
The total rainfall during the months June, July and August = 150 cm
(a) The average rainfall per month during these three months(June, July and August).
Total rainfall in these three months / Number of months
= 150/3
= 50 cm
(b) The total rainfall during the entire year 2014
= The average rainfall per month throughout the year x Number of months
= 23 x 12
= 276 cm
(c) The average rainfall per month during the other 9 months:
The total rainfall in the other 9 months = Total rainfall throughout the year - Total rainfall for 3 months(June, July, August)
= 276 - 50
= 226 cm
The average rainfall per month during the other 9 months = The total rainfall during the 9 months / Number of months
= 226/9
= 75.33 cm
Step-by-step explanation:
1) avarage rainfall of three month =total rainfall/no.of months
avarage = 150/3= 50 cm
2) total rainfall of entire year =avarage rainfall *no.of months.
= 23*12 = 276 cm
3) the avarage rainfall per month during the other 9 month = total rainfall of entire year - total rainfall of 3 months / no.of months
276- 150 =126
126/9= 14 cm
