The density d of a substance Is given by the formula d=M/v, where M Is It’s mass and V Is it’s volume.

Density: 5.01g/cm3 volume: 1.2 cm3

A. Solve the formula for m.

B. Find the mass of the pyrite sample.

1: 12

2:Yes

explanation=

18+-6=12

so she's good

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3
