Lin is building a cylindrical planter with a base diameter of 15 inches. She has 5,000 cubic inches of soil to fill her planter.
Anton [14]

Answer:

h=28\ in

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

V=\pi r^{2}h

we have

V=5,000\ in^3

r=15/2=7.5\ in ----> the radius is half the diameter

\pi =3.14

substitute the given values

5,000=(3.14)(7.5)^{2}h

solve for h

h=5,000/[(3.14)(7.5)^{2}]

h=28\ in

The ratio of men to women working for a company is 5 to  8 . If there are 364 employees total, how many men work for the company
uysha [10]
5 'parts' of the total company staff are men, and 8 'parts' are women.
That's 13 'parts' all together, comprising 364 people.
So each 'part' is 364/13 = 28 people.

Men = 5 'parts' = 5 x 28 = <u>140 men</u>

Women = 8 'parts' = 8 x 28 = <u>224 women</u>

<em><u>Check:</u></em>

140/224 = 70/112 = 35/56 =<em> </em><em>5/8</em>

140 + 224 = <em>364</em>

yay !

Thank you for posting you question here at brainly. Below is the solution:

1/97 = 1 / (100-3) = 1 / (xo + dx) 

<span>so, you have now that </span>

<span>x = xo + dx, where x = 97, xo = 100, and dx = - 3. Recognizing that 3 << 100, we can write the Taylor expansion around xo </span>

<span>1/ (xo + dx) ~ 1/xo + d/dx(1/xo)dx = 1/xo + (-1/xo^2)dx </span>

<span>= 1/100 - (1/100^2) (-3) = 1/100 + 3/100^2 </span>
<span>= 1/100 + 3/10000 </span>
<span>= 0.01 + 0.0003 </span>
<span>= 0.0103 </span>
