Diamonds have a density of 3.5 LaTeX: \frac{g}{cm^3}g c m 3. How big is a diamond that has a mass of 0.10 g?

liubo4ka [24]

For this case we have that by definition, the density is given by:

$d = \frac {M} {V}$

Where:

M: It is the mass of the diamond

V: It is the volume of the diamond

According to the data of the statement we have:

$d = 3.5 \frac {g} {cm ^ 3}\\M = 0.10 \ g$

So the volume is:

$V = \frac {M} {d}\\V = \frac {0.10 \ g} {3.5 \frac {g} {cm ^ 3}}\\V = 0.02857\\V = 0.03 \ cm^3$

Thus, the volume of the diamond is approximately $0.03 \ cm ^ 3$

Answer:

$0.03 \ cm ^ 3$

The radio broadcast of AM station KTBC can be heard in the neighboring towns of Waterville and Newport. Of the total number of r

maria [59]

Answer: The required probability is 22.5%.

Step-by-step explanation:

Since we have given that

Probability of radio listeners live in Waterville = 0.75

Probability of radio listeners live in Newport = 0.25

Probability of radio station KTBC in Waterville = 0.20

Probability of radio station KTBC in Newport = 0.30

So, using "Multiplication rule of Probability":

Probability that the listener will be tuned in to station KTBC is given by

$0.75\times 0.20+0.25\times 0.30\\\\=0.15+0.075\\\\=0.225\\\\=22.5\%$

Hence, the required probability is 22.5%.

120 ≤ 12 k + 29 need help

Aleksandr [31]

The answer is $k$ ≥ $\frac{91}{12}$

First, you must flip the equation

$12k+29$ ≥ $120$

Then, you must subtract 29 on both sides

$12k$ ≥ $91$

Finally, divide both sides by 12

$k$ ≥ $\frac{91}{12}$
