An aluminum block has a mass of 82.0 g and a volume of 12.8 cm3. what is the block's density to the nearest g/cm3?

The density of the  aluminum block is 6.41 g per cm³ .

Step-by-step explanation:

Formula

As given

An aluminum block has a mass of 82.0 g and a volume of 12.8 cm³.

Mass = 82.0 g

Volume = 12.8 cm³

Put in the formula

Density = 6.41 g per cm³ (Approx)

Therefore the density of the  aluminum block is 6.41 g per cm³ .

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

i believe the answer is c.
