I can only give you study advice that worked for me....practice a lot of problems. One more thing....if you know the proceedure, don't spend too much time on that particular problem. I found that most of my problems on tests came from material I was uncomfortable with, so that's where you should spend most of your study time.

5/5 =1

So we have

1 / (1/2)     so we invert the denominator and multiply it by the numerator =

1 * (2 / 1 ) =

1 * 2 =

2

That's it.....

V = L X W x H

So, dividing both sides by W x H, we get

V / (W x H )   =  L

And that's it....

Just add 2*pi  to -(3/4) pi to get your angle...in this case, we would get (5/4) pi

If you're asking this

√(20 + 2) = √(22)     then it's true

If you're asking this

√(20) + (2) =  √(22)    then it's not true

8x^2+12x+1=0

$${\mathtt{8}}{\mathtt{\,\times\,}}{{\mathtt{x}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{1}} = {\mathtt{0}} \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = {\mathtt{\,-\,}}{\frac{\left({\sqrt{{\mathtt{7}}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{3}}\right)}{{\mathtt{4}}}}\\ {\mathtt{x}} = {\frac{\left({\sqrt{{\mathtt{7}}}}{\mathtt{\,-\,}}{\mathtt{3}}\right)}{{\mathtt{4}}}}\\ \end{array} \right\} \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = -{\mathtt{1.411\: \!437\: \!827\: \!766\: \!147\: \!6}}\\ {\mathtt{x}} = -{\mathtt{0.088\: \!562\: \!172\: \!233\: \!852\: \!4}}\\ \end{array} \right\}$$

I'm just going by what the site said.........

According to the National Geophysial Data Center:

660,000,000 km³

From the data, it appears there were 43 in the Senate and 176 in the House = 219 total
