4 0

2 tenths can also be written as 0.2. Now let's look at each answer.

2 hundredths is 0.02
200 hundredths is 2.00
20 hundredths is 0.20

Aha! That is the same as two tenths. So the answer is the third option, 20 hundredths.

Air has a density of 0.001226 g/mL. What volume of air would have a mass of 1.0 lb? A. 2.7 mL B. 815.6 mL C. 37 mL D. 3.7 × 102

Answer:

$Volume = 3.7\ * 10^2\ L$

Step-by-step explanation:

Given

$Density = 0.001226 g/mL$

$Mass = 1.0\ lb$

Required

Determine the volume of air

Density is calculated using:

$Density = \frac{Mass}{Volume}$

Substitute values for Density and Mass

$0.001226 g/mL = \frac{1.0\ lb}{Volume}$

Convert lb to grams

$0.001226 g/mL = \frac{1.0 * 453.592\ g}{Volume}$

$0.001226 g/mL = \frac{453.592\ g}{Volume}$

Solve for Volume

$Volume = \frac{453.592\ g}{0.001226 g/mL}$

$Volume = 369977.161501\ mL$

Convert mL to L

$Volume = 369977.161501\ L * 0.001$

$Volume = 369.977161501\ L$

Represent using scientific notation

$Volume = 3.69977161501\ * 10^2\ L$

Approximate

$Volume = 3.7\ * 10^2\ L$

Answer:

$2.3\:\mathrm{in^3},\\1.3\:\mathrm{fl\:oz}$

Step-by-step explanation:

The volume of a cone with radius $r$ and height $h$ is equal to $V=\frac{1}{3}\cdot r^2\pi\cdot h$ .

What we're given:

Since radius is half the diameter, $r$ is $1.1$
Height of $1.8$

Substituting given values, we get:

$V=\frac{1}{3}\cdot 1.1^2\pi \cdot 1.8=0.726\pi\approx \boxed{2.3\:\mathrm{in^3}}$

Convert to fluid ounces using the conversion given in the question:

$0.726\pi}\cdot \frac{0.554}{1}\approx \boxed{{1.3\:\mathrm{fl\:oz.}}}$
