How much of the earth’s water is usable as a freshwater resource? a. 75% b. 3% c. 100% d. 25%

A. 75%

Explanation: According to the U.S. Geological Survey, most of that three percent is inaccessible.

b. 3%

Explanation:

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
