Physical Science
If the density of ice is 0.92 g/cm^3, what percent of an ice cube’s (or iceberg’s) mass is above water.

Physical Science
How does the apparent weight loss of the an object compare with the weight of the water displaced by the object?

math
...I already solved one for you just like this...

math
And please type the whole equation next time. We do not have ESP.

math
5+2(x-1) = 12 5+2x-2 = 12 5+2x = 14 2x = 9 x = 9/2 (which is 4.5)

math
5+2(x-1) = 0 5+2x-2 = 0 5+2x = 2 2x = -3 x = -3/2 (which is -1.5)

science

chemistry
Q=cm(Tf-Ti) Q = the heat of an object m = the mass c = the heat capacity of the substance Tf= the final temperature Ti= the initial temperature Q gained by water = Q lost by copper Make sure your units go together.

Science
x = time (independent) y = distance (dependent) horizontal: y isn't changing diagonal: y is increasing at a constant rate

history
There's also plenty of links on the bottom of the Wikipedia article under "External Links".
