Which numbers are irrational

1 answer:

6 0

"An irrational number can't be expressed as a ratio between 2 numbers, it can't be written as a simple fraction because there is not a finite number of numbers when written as a decimal. The numbers in the decimal would go on forever, without repeating.

Train revived a raise of $80 per week. If he was making $500 per week before the raise, what is the percent change in his earnin

kotegsom [21]

Answer:

Train got a raise of 16%

Step-by-step explanation:

To find this, start by taking the equation for percent change

(New - Old)/Old * 100 = % Change

Now plug in known values

(580 - 500)/(500) * 100 = % change

80/500 * 100 = % change

.16 * 100 = % change

16 = % change

Check the picture below.

notice the alternate interior angles in the picture.

$\bf tan(68^o)=\cfrac{\stackrel{opposite}{1.5}}{\stackrel{adjacent}{x}}\implies x=\cfrac{1.5}{tan(68^o)}\implies x\approx 0.61 \\\\[-0.35em] ~\dotfill\\\\ tan(56^o)=\cfrac{\stackrel{opposite}{1.5}}{\stackrel{adjacent}{w}}\implies w=\cfrac{1.5}{tan(56^o)}\implies w\approx 1.01 \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill \stackrel{\textit{width of the crater}}{x+w\implies 1.62}~\hfill$
