Make f(x)=g(x), so -x^2+4x+1=x+1, s=0, x=3. Select 0 and 3.

The total amount is 8 choose 3 or 56 triangles.

Not sure, I'm getting 56?

Try again; you're close through. 

Thus, (C) fits the option!

We have 46+22+319+73=460 people unemployed. In total, we have 1017+649+2715+919+460=5760 people. Thus, \(\frac{460}{5760}*100\approx8\) or (B).

We can also use the clock formula, which is \(|30H-5.5M|\), so \(|30(12)-5.5(30)|=360-165=195^\circ\). Since the problem is asking us for the smaller angle, the answer is \(\boxed{165^\circ}\).

We just take the cube root of this number, @Guest. Solving, we get \(\sqrt[3]{216}\) or \(\boxed{6}\) centimeters. 

The inradius of a polygon can be found by \(A=rs\), where \(A\) is the area, \(r\) is the inradius, and \(s\) is the semi-perimeter. We know that the area is \(\frac{1}{2}*6*8=24\), based on the information given, and \(\frac{6+8+10}{2}=12\) which is considered the semi-perimeter. Now, we have to solve for the radius, and plugging our values in, we reach \(24=12r, 12r=24, \boxed{r=2}\). 

I agree with @CPhill! We have \(\frac{5a+4a^2}{20}\) after joining \(\frac{a}{4}+\frac{a^2}{5}\), together. Now. we have \(\frac{\frac{5a+4a^2}{20}}{25}\) which is \(\frac{5a+4a^2}{20\cdot \:25}\), or our final answer of \(\frac{5a+4a^2}{500}.\)
