The answer is 42. Divide by 36 each sides to get rid of 36. Then, the answer you get after you divide by 36 on each side is 42. Hopefully That helped :)

Answer:

$\frac{2}{15}$

Step-by-step explanation:

<h2><u>Lesson : Probability</u></h2><h2><u></u></h2>

We have a bag with 4 white chips and 6 black chips
Question : What is the probability of randomly choosing a white chip, not replacing it, and then randomly choosing another white chip?

4 white and 6 black

4 + 6 = 10

Choosing the first white chip : $\frac{2}{5}$

Since we took one out , now

3 white chips , 6 black chips

3 + 6 = 9

Choosing another white chip : $\frac{1}{3}$

$\frac{2}{5} * \frac{1}{3}$

$\frac{2}{15}$

Mercury has a density of 13.6 g/mL. A sample of mercury weighs 2.25 kg. What volume does it occupy

laila [671]

Answer:

165 mL

Step-by-step explanation:

Density is mass divided by volume:

D = M / V

Solving for volume:

V = M / D

The density is given in g/mL. So first let's convert the mass from kg to g:

2.25 kg × (1000 g / kg) = 2250 g

Plugging in values:

V = (2250 g) / (13.6 g/mL)

V = 165.4 mL

Rounded to 3 significant figures, the volume is 165 mL.
