Q4 How are Northern plains fertile. Give reason.

The Northern Plain was formed by the deposits brought in by the three major rivers and their tributaries. Alluvium was deposited at the foot–hills of the Himalayas for millions of years. These deposits are now the fertile Northern Plains. Alluvium is soil or sediments deposited by a river or other running water.

hello from mrbilldoesmath!

answer:

104 f = 40 c

discussion:

9/5c + 32 = f               => in our case, f = 104

9/5c + 32 = 104           => subtract 32 from both sides

9/5c         = 104 - 32   =>

9/5c   = 72                   => multiply both sides by 5/9 (the reciprocal of 9/5)

(5/9)*(9/5) c = 72 * (5/9) =>

c = 72*5/9 = 360/9 = 40
