Gold is alloyed with different metals to make it hard enough to be used in jewelry. The amount of gold present in a gold alloy is measured in 24ths called karats. 24-
karat gold is 100% gold. Similarly, 18-karat gold is 75% gold. How many ounces of
14-karat gold should be added to an amount of 8-karat gold to make 6 ounces of
12-karat gold? Graph equation(s) on coordinate axes with labels and scales. *

answer: y = -2.5x - 15

step-by-step explanation:

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
