While training for a marathon, todd runs
12.5 miles on monday, 15.6 miles on
tuesday, 19.25 miles on wednesday,
20.45 miles on thursday, and 13 miles
on friday. how many miles did he run
monday through friday?

I think it's 80.8 miles.

Explanation:

You would add Monday through Fridays miles up, using basic addition with rounding. So 12.5 plus 15.6 equals 28.1 miles. Then you'd add 28.1 miles to 19.25 miles. And you'd add the number you add to the next number of miles.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
