we know B is the midpoint, thus it cuts AC into two equal halves.

Might help if you write the equation
Answer: ~2.45 cups, or A
Step-by-step explanation:
First, find the area of the circle. Area formula is
, but instead of the radius, we have the diameter. Halve the diameter to get the radius of 10 inches.
A = pi * 100
So the pizza has an area of around ~314.15 square inches.
Divide this number by 16 square inches to find how many 1/8 cups Tony uses.
314.15/16 = ~19.63 1/8 cups.
You can then divide 19.63 by 8 to receive how many cups he uses.
Answer:
y = 1/2x + 2
Step-by-step explanation:
y = mx+b, where m is the slope, b is y-int, and y and x are variables.
Step 1: find the y-int: 2. Using this you can out rule C and D.
Step 2: find the RISE/RUN: 1/2. This is your slope.
Step 3: fill in your equation.
Hope that helps
<span>3x=7y+16
15y=7y + 16
15y - 7y = 16
8y = 16
y = 8/16
y = 2
hope this helps you !!! =')</span>
