Mathematics

Okay, so first things first:
i = \sqrt{-1} 

That said, no answer that has -245 is correct.

Now we just need to solve \sqrt{245}
245/5=5*49
\sqrt{5}  * \sqrt{49} = 7i*\sqrt{5}
So, that's your answer, option D.

You make $5000 per morth. If you spend 50% on necessitles, 30% on stuff you want and 20% of it you end up saving, how much money
liubo4ka [24]

Answer:

$1000 per month

Step-by-step explanation:

5000 dollars is 100 percent so we put 5000 over 100

5000/100

then since we need to find 20 percent of something, we put x over 20

x/20

Then we cross multiply

<u>5000</u>      times       <u>x   </u>            

100                        20

so 100x = 100000

and x = 1000

Good luck, and hope I did this correctly
