A sample of marble has a volume of 6 cm3 and a density of 2.76 g/cm3. What is its mass?

Drupady [299]

Answer:

$16.56\ g$

Step-by-step explanation:

we know that

The density is equal to the mass divided by the volume

Let

x-----> the mass of marble

y----> the volume of marble

z----> the density of marble

$z=\frac{x}{y}$

in this problem we have

$y=6\ cm^{3}$

$z=2.76\ g/cm^{3}$

substitute and solve for x

$2.76=\frac{x}{6}$

$x=2.76*6=16.56\ g$

ICE Princess25 [194]

Plug in -3 for x
f(-3) = 2(-3) - (-3 + 6)
f(-3) = -6 - (3)
f(-3) = -9
Solution: f(-3) = -9

A family swimming pool holds 61 m3 of water. It loses 0.27m3 of water to evaporation each day. This situation can be represented

Bezzdna [24]

Answer:

The answer to your question is: when x = 100 days, y = 34 m³

Step-by-step explanation:

Data

Volumen = 61 m³

Loses 0.27 m³ each day

Equation y + 0.27x = 61

when x = 100, y = ?

Process, just substitute x in the equation and solve it for y

y + 0.27(100) = 61

y + 27 = 61

y = 61 - 27

y = 34 m³

It means that after ten days, the swimming pool will only have 34 m³, because 27 m³ will have evaporated.
