Well to find this out you need to make an equation
s+7=j
So for example if Johnny's sister is 15 then Johnny would be 22 because
s(sister's age) +7(number of years difference between their ages)=22(Johnny's age)
The study demonstrates that the atmosphere manages 78% of the total heat movement in the Northern Hemisphere and 92% in the Southern Hemisphere at 35 degrees latitude based on a reanalysis of data collected between February 1985 and April 1989.
The Northern Hemisphere and Southern Hemisphere are imaginary geographic divisions that divide Earth into two equal halves at the prime meridian or the equator, respectively. The portion of Earth south of the equator, an imaginary horizontal line that circles the planet halfway between its poles, is known as the southern hemisphere. The Southern Hemisphere touches four oceans—the Indian, South Atlantic, Southern/Antarctic, and South Pacific—and at least a piece of five continents.
