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 .

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
