defon

Answer:

y=4/3x-2

Step-by-step explanation:

We know the base equation is mx+b and the y-intercept is at -2 so we can determine that as the b value. The m value is 4/3 because if you look at where the line meets the next point is over 3 and up 4 indicating that the m value is 4/3. Hope this helps!

A pizza with radius 7 in. is cut into 12 equal-sized pieces. What is the area of each piece? Round to the nearest hundredth of a
dimaraw [331]

Answer:

Area of one piece of pizza ≈ 12.83 inches

Step-by-step explanation:

First of all let's calculate the area of the pizza.

Pizza is circular in shape, thus,

Area; A = πr²

We are given the radius;r = 7 inches

So, A = π(7²) = 153.94 in²

Now, since the area is divided into 12 equal sized pieces, thus we will divide the total area we got by 12 to get the area of one piece.

Area of one piece of pizza = 153.94/12 ≈ 12.83 inches
