4. a certain 3d printer uses 100 m of plastic filament that is 1.75 mm in diameter to make a cup. if the filament has a density of 0.32 g/cm3, find the mass of the cup to the tenths place.

m=77.1g

Step-by-step explanation:

First of all we need to calculate the volume of the filament.

we need to convert m^3 to cm^3

The density is given by:

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
