Answer:

20 (.8) = 16

It takes him 16 minutes to walk to school.  

This is because 80% as a decimal is .8 and you multiply that by how long it takes Person A to walk and you get 16.

Answer:

It 20 minutes for 80 percent so if we divided 80 by 20 =4if we timed it by 5 it will give us the other 20 percent so the answer is 4

Prove the following
fomenos

Answer:

Step-by-step explanation:

\large\underline{\sf{Solution-}}

<h2 /><h2><u>Consider</u></h2>

\rm \: \cos \bigg( \dfrac{3\pi}{2} + x \bigg) \cos \: (2\pi + x) \bigg \{ \cot \bigg( \dfrac{3\pi}{2} - x \bigg) + cot(2\pi + x) \bigg \}cos(23π+x)cos(2π+x)

<h2><u>W</u><u>e</u><u> </u><u>K</u><u>n</u><u>o</u><u>w</u><u>,</u></h2>

\rm \: \cos \bigg( \dfrac{3\pi}{2} + x \bigg) = sinx

\rm \: {cos \: (2\pi + x) }

\rm \: \cot \bigg( \dfrac{3\pi}{2} - x \bigg) \: = \: tanx

\rm \: cot(2\pi + x) \: = \: cotx

So, on substituting all these values, we get

\rm \: = \: sinx \: cosx \: (tanx \: + \: cotx)

\rm \: = \: sinx \: cosx \: \bigg(\dfrac{sinx}{cosx} + \dfrac{cosx}{sinx}

\rm \: = \: sinx \: cosx \: \bigg(\dfrac{ {sin}^{2}x + {cos}^{2}x}{cosx \: sinx}

\rm \: = \: 1=1

<h2>Hence,</h2>

\boxed{\tt{ \cos \bigg( \frac{3\pi}{2} + x \bigg) \cos \: (2\pi + x) \bigg \{ \cot \bigg( \frac{3\pi}{2} - x \bigg) + cot(2\pi + x) \bigg \} = 1}}

HELP Luna observed that in the last 12 issues of Rise Over Run Weekly, 384 of the 960 pages contained an advertisement.
Veseljchak [2.6K]
Well, 12 issues end up as 960 pages total

so... if in 960 pages, 384 are ads, what about 80 pages?

well \bf \begin{array}{ccllll}&#10;pages&ads\\&#10;\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\&#10;960&384\\&#10;80&x&#10;\end{array}\implies \cfrac{960}{80}=\cfrac{384}{x}

solve for "x"
