Write 0.81 as a fraction in simplest from

Mathematics
1 answer:
Kazeer [188]3 years ago
7 0

Answer:

81/100

Step-by-step explanation:

Here's how to convert 0.81 to a fraction...

There is not much that can be done to figure out how to write 0.81 as a fraction, except to literally use what the decimal portion of your number, the .81, means.

Since there are 2 digits in 81, the very last digit is the "100th" decimal place.

So we can just say that .81 is the same as 81/100.

So your final answer is: 0.81 can be written as the fraction 81/100

A cylinder has a volume of 360 cubic centimeters. Find the volume of a cone with the same height and diameter as the cylinder.
ratelena [41]

The formula of a volume of a cylinder:

V_{cylinder}=\pi r^2H

The formula of a volume of a cone:

V_{cone}=\dfrac{1}{3}\pi r^2H

If a cone and a cylinder have the same radius and the same height, then a volume of a cylinder is three times greater than a volume of a cone.

V_{cylinder}=3V_{cone}\\\\V_{cone}=\dfrac{1}{3}V_{cylinder}

V_{cylinder}=360\ cm^3

V_{cone}=\dfrac{1}{3}\cdot360\ cm^3=120\ cm^3

<h3>Answer: The volume of a cone is equal 120 cm³.</h3>

You are a sportswriter for a newspaper. Today you are writing an article about a professional basketball player. During the play
Paha777 [63]
For this case we can make the following rule of three:
 1507 ----> 100%
 1213 ----> x
 Clearing the value of x we have:
 x = (1213/1507) * (100)
 x = 80.4910418
 Rounding off we have:
 x = 80.5%
 Answer:
 
this player has made 80.5% of free throws

Korvikt [17]

Answer:

\huge \boxed{\red{ \boxed{  -  \cos(x)  + C}}}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • integration
  • PEMDAS
<h3>tips and formulas:</h3>
  • \tan( \theta)  =  \dfrac{ \sin( \theta) }{ \cos( \theta) }
  • \sf \displaystyle \int  \sin(x)   \: dx =    - \cos(x)  +   C
<h3>let's solve:</h3>
  1. \sf \: rewrite \:  \tan( \theta)  \:  as \:   \dfrac{ \sin( \theta) }{ \cos( \theta) }  :  \\   =  \displaystyle  \int \:  \frac{ \sin(x) }{ \cos(x) }  \cos(x)  \: dx \\   = \displaystyle \int \:  \frac{ \sin(x) }{ \cancel{\cos(x) }}   \: \cancel{ \cos(x)}  \: dx \\     = \displaystyle \int \:  \sin(x)   \: dx
  2. \sf \: use \: the \: formula : \\   \sf \displaystyle     - \cos(x)
  3. \sf add \: constant :  \\   -  \cos(x)  + C
