Answer:
.003508 kg of copper
Step-by-step explanation:
1000 grams = 1 kg
3.508 g/1000 g = .003508 kg
<span>The easiest thing to do is convert all the measurements to yards...
18ft = 6 yards
6 inch = 1/6 yard ( 6 inches = 1/2 ft.... so 1/6 yard)
so the volume is
V = 6 x 6 x 1/6
Then all you do is calculate the cost. I hope this helps you out</span>
-4x+7x-14
3x-14>-18
3x>-4
X>-4/3
20x+20y=900
I hope that helps. You'll have to isolate each variable. X= kite, y=website.
