If you can buy 8 cans of corn for 3.20 how much would 48 cans cost

$19.20

Explanation:

divide 3.20 by 8 in order to get the cost of 1 can

3.20/8 = 0.40

multiply the cost of 1 can ($0.40) by 48 in order to get the cost of 48 cans

0.40 * 48 = 19.20

$19.20 for 48 cans of corn

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
