A secretary can type 12 pages per hour. There are a total of 152 pages to type. How many pages remain to be typed after 9 hours?
mr_godi [17]
So, she can type 12 pages in 1 hour, how many would she type in 9 hours then?  let's check,

\bf \begin{array}{ccll}
pages&hours\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
12&1\\
p&9
\end{array}\implies \cfrac{12}{p}=\cfrac{1}{9}\implies \cfrac{12\cdot 9}{1}=p

so in 9 hours, she has that typed that many pages, how many pages remain from the 152?  well 152 - p.

A sphere and a cone have the same volume. The sphere has a radius x and height y. The cone has a radius of 1/2x. Find the height
notka56 [123]

Answer:

h = 16x

Step-by-step explanation:

The volume of a sphere and a cone is same such that,

V_s=V_c\\\\\dfrac{4}{3}\pi r^3=\dfrac{1}{3}\pi R^2h

We have, r = x, R = (1/2)x, h= ? (height of the cone)

So,

\dfrac{4}{3}\pi x^3=\dfrac{1}{3}\pi (\dfrac{x}{2})^2h\\\\4x^3=\dfrac{x^2}{4}h\\\\h=\dfrac{16x^3}{x^2}\\\\h=16x

So, the height of the cone is equal to 16x.

Can someone please help, ty!!<br> Will mark brainliest!
PolarNik [594]

The sum of the interior angles of a triangle is 180 degrees. Therefore, if we add up all of these angles, they will equal 180.

82 + 55 + x = 180

137 + x = 180

x = 43 degrees

Hope this helps!! :)
