A tessellation is the regular t<span>iling of a plane shape</span>
You need to set up proportions:
3/8=x/192
(3 cups to 8 ounces = x cups to 192 ounces)
cross multiply:
8x=3×192
8x=576
x=72
72 cups are needed
-100% is the same as -100/100
so, -100/100+0.58 = -1+0.58 = -0.42
6/15=height of lamp/(15+15); 6/15=height of lamp/30; height of lamp=(30/15)6=2×6, 2 times taller.
(Lamp is 12 feet tall)
