Please help with the answer below

kenny6666 [7]

Answer:

$f(x) = \frac{x + 7}{6 - x} \\ \frac{3}{2} = \frac{x + 7}{6 - x} \\ 3(6 - x) = 2(x + 7) \\ 18 - 3x = 2x + 14 \\ - 3x - 2x = 14 - 18 \\ - 5x = - 4 \\ \frac{ - 5x}{ - 5} = \frac{ - 4}{ - 5} \\ x = \frac{4}{5}$

oakwood has a mass of 2.85 kilograms and a volume of 4100 cubic centimeters. determine the density of oak in grams per cubic cen

bogdanovich [222]

Answer:

The density of oak is <u>0.695</u> grams per cubic centimeter.

Step-by-step explanation:

Given:

Oakwood has a mass of 2.85 kilograms and a volume of 4100 cubic centimeters.

Now, to find the density of oak in grams per cubic centimeter.

Mass (m) = 2.85 kilograms.

So, using conversion factor we convert into grams:

$2.85\times 1000=2850\ grams.$

Volume (v) = 4100 cubic centimeters.

Now, to get the density by using formula:

$Density=\frac{mass}{volume} \\Density=\frac{m}{v}$

$Density=\frac{2850}{4100}$

$Density=0.695\ grams\ per\ cubic\ centimeter.$

Therefore, the density of oak is 0.695 in grams per cubic centimeter.
