Approximately 4/5 of u.s. homeworkowners have a cell phone.what percent of homeowners do not have a cell phone?

1 answer:

3 0

So you need to get the fraction to a percentage. Divide 100 by 5 to see how much you need to multiply the 4 by. 100/5 is 20. So you times the 4 by 20 to get 80. 80% have a cellphone so simply minus 80 from 100 to get your answer of those who don't. Therefore the answer is 20.

Answer:

The volume of the solid is π/40 cubic units.

Step-by-step explanation:

Please refer to the graph below.

Recall that the area of a semi-circle is given by:

$\displaystyle A=\frac{1}{2}\pi r^2$

The volume of the solid will be the integral from x = 0 to x = 1 of area A. Since the diameter is given by y, then the radius is y/2. Hence, the volume of the solid is:

$\displaystyle V=\int_0^1\frac{1}{2}\pi \left(\frac{y}{2}\right)^2\, dx$

Substitute:

$\displaystyle V=\frac{1}{2}\pi\int_0^1\left(\frac{x^2}{2}\right)^2\, dx$

Simplify:

$\displaystyle V=\frac{1}{2}\pi \int_0^1\frac{x^4}{4}\, dx$

Integrate:

$\displaystyle V=\frac{1}{2}\pi \left[\frac{x^5}{20}\Big|_0^1\right]$

Evaluate:

$\displaystyle V=\frac{\pi}{40}\left((1)^5-\left(0\right)^5\right)=\frac{\pi}{40}\text{ units}^3$

The volume of the solid is π/40 cubic units.

Pablo has to paint $\frac{1}{3}$ more murals.
Painted mural to jar of paint ratio: $\frac{2}{3} paintedmurals: \frac{4}{5} jarofpaint$
Simplify the ratio.
$\frac{1}{3} paintedmurals: \frac{2}{5} jarsofpaintused$
Pablo needs 2/5 jars of paint per each 1/3 painted murals
$3*\frac{2}{5}$
$\frac{6}{5}$
