The density of Styrofoam is 0.03 ounce per cubic inch. What is its density in grams per cubic centimeter? Will it float in water

kumpel [21]

The density of Styrofoam in grams per cubic centimeter is $0.052 \ \frac{g}{cm^3}$ .

The density of the Styrofoam is less than 1, hence it will float in water.

The given parameters;

density of Styrofoam = 0.03 ounce per cubic inch

To find:

the density in grams per cubic centimeter

1 ounce = 28.35 gram

1 in³ = 16.3871 cm³

The density of Styrofoam in grams per cubic centimeter is calculated as follows;

$\rho = \frac{0.03 \ ounce}{in^3} \times \frac{1 \ in^3}{16.3871 \ cm^3} \times \frac{28.35 \ g}{1 \ ounce} = 0.052 \ \frac{g}{cm^3}$

Since the density of water is $1 \ \frac{g}{cm^3}$ , and the density of the Styrofoam is less than 1, hence the Styrofoam will float in water.

Find the x value do that the line through the points (x,-9) and (0,1) has a slope of -4 PLEASE ANSWER

Wittaler [7]

$\bf (\stackrel{x_1}{x}~,~\stackrel{y_1}{-9})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{1-(-9)}{0-x}=\stackrel{\stackrel{slope}{\downarrow }}{-4}\implies \cfrac{1+9}{-x}=-4 \\\\\\ \cfrac{10}{-x}=-4\implies 10=4x\implies \cfrac{10}{4}=x\implies \cfrac{5}{2}=x$
