A block of cheese has a volume of 187 cm3 and a mass of 140 g. What is the density of the cheese in g/cm3 rounded to 2 decimal places?

Step-by-step explanation:

Density can be found by dividing the mass by the volume.

The mass of the block of cheese is 140 grams and the volume is 187 cubic centimeters.

Substitute the values into the formula.

Divide.

Round to the hundredth place (2 decimal places).

The 8 in the thousandth place tells us to round the 4 to a 5.

The density is about 0.75 grams per cubic centimeters.

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
