To solve the problem “56 is what percent of 70?”, Noah uses the double number line below. On the double number line, write the correct numbers at each unlabeled tick mark. Then solve the problem. A double number line with 5 tick marks. The first 2 tick marks are toward the left end of the number line and the other 3 are toward the right end. For the top number line, the tick marks are 0, 7, unlabeled, unlabeled, 70. For the bottom number line, the tick marks are 0%, 10%, unlabeled, unlabeled, 100%.

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.
