Question

the sum of the temperatures for the month of February is 756 Celsius. calculate the number of days in February, if the average temperature of the month is 27 Celsius. 3 days of the week is 28 Celsius and the next three days is 30° C. find the temperature of the last day, if weekly average is 28 Celsius. ​

Answer 1

Answer :-

28 days and 22 C.

Step-by-step explanation:

Given the sum of the temperatures for the month of February is 756 Celsius.

No of days in February=?

and given Avg. temperature for the month of February is 27 C.

then 756 / ? = 27

? = 756/27

? = 28

Here ? = no. of days in the month of February

then February has 28 days.

And now we have to find temperature of the the last day in a week and given if first 3 days recorded 28 C and next 3 days recorded 30 C and weekly Avg. is 28 C.

then [(3*28)+(3*30)+?]/7=28 [Because weekly Avg is given 28]

84+90+? = 196

174+?=196

?=196-174

?=22 C

Here ? = temperature recorded on last day of the week.

then Temperature of the last is 22 C
