Answer:

its 160 because 20 x 8 equals 160

we know the diameter of the pizza is 20", that means the radius of it is half that or 10".

\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=10 \end{cases}\implies A=\pi 10^2\implies A=100\pi \\\\\\ \stackrel{\textit{ divided by 8}}{\cfrac{100\pi }{8}\implies \cfrac{25\pi }{2}}\qquad \qquad \stackrel{\textit{how much for two slices of that?}}{\cfrac{25\pi }{2}+\cfrac{25\pi }{2}\implies \cfrac{50\pi }{2}}\qquad \approx \qquad 78.54

Use the discriminant to describe the roots of each equation. Then select the best description. x2 - 5x + 7 = 0
miv72 [106K]
The general form of a quadratic (second degree) equation is 

a x^{2} +bx+c=0, where

D= b^{2}-4ac is called the Discriminant.


The Discriminant determines how many roots the equation will have as follows:

i)  if D>0, the equation has 2 roots.
ii) if D=0, the equation has 1 double root.
iii) if D<0, the equation has no roots.


In our equation, x^{2} -5x+7=0, a=1, b=-5, c=7

so the discriminant is D=(-5)^2-4*1*7=25-28<0


Thus the equation has no roots.


Remark: the equation has no roots in the Real numbers, but it has 2 roots in a larger set of numbers to be discussed in the future, the Complex numbers.
