The density of pure solid copper is 8.94 g/mL. What volume does 5 kg of copper occupy. Please help

1 answer:

5 0

Density= Mass divided by Volume, but you're trying to find Volume so you apply Algebra and get Volume= Mass divided by Volume.

Volume= 0.5592841163 [kg/m (power to the 3)]

You should round it up

What is an equation of the line that is parallel to y=4x−10 and passes through (1, 13) ?

klasskru [66]

If a line is parallel to another line,Then the gradients are the same.So m=4 .Using general formula for str8 line, y=mx+c
$y = 4x + c$
sub in coorfinates (1,13)
$13 = 4 + c$
So C=9.
$y = 4x + 9$
