Answer:

67.02\ in^2

Step-by-step explanation:

-We find the surface area of the formula as follows:

A=\pi r^2, \ \ r=radius=8\ in\\\\=\pi \times 8^2\\\\=201.06\ in^2

#We then find the area of the remaining fraction if she only ate one third:

Eaten=\frac{1}{3}\times Area\\\\=\frac{1}{3}\times 201.06\ in^2\\\\=67.02\ in^2

Hence, Tina ate 67.02\ in^2 of the pizza.

F(x) = 1 / (x - 2)...when x = 4
f(4) = 1 / (4 - 2)
f(4) = 1/2 <==

f(x) = 1 / (x - 2)...when f(x) = 1
1 = 1 / (x - 2) ...multiply both sides by (x - 2) eliminating it on the right
1(x - 2) = 1
x - 2 = 1
x = 1 + 2
x = 3 <==

in the equation 6x – 2 = –4x + 2, Spencer claims that the first step is to add 4x to both sides. Jeremiah claims that the first
trapecia [35]
Spencer would be the correct one because it's easier to keep your variables positive when trying to solve. Therefore, in order to keep the variable positive, one would have to add 4x to both sides.
