Answer:
8 slices
Step-by-step explanation:
To answer this question, we first need to know the area covered by the pizza.
Since it is circular in shape, we use the formula for the area of a circle.
Mathematically area of a circle = pi * r^2
Here, we were given the diameter but we know that D = 2r or r = D/2. This shows that the radius would be 14/2 = 7 inches
Now the area of the pizza is 22/7 * 7 * 7 = 22 * 7 = 154 square inch
Now we proceed to calculate the amount in calories present in the pizza;
That would be 154 * 14.04 = 2162.16 calories
one slice has 270 calories; The number of slices in 2162.16 calories would be 2162.16/270 = 8.008 which is approximately 8 slices

ANSWER IS 8.55
Answer:
Step-by-step explanation:
remeber that idical laws
For the equation y = 2x + 3, calculate the x and y intercepts
when y = 0
0 = 2x + 3
x = -3/2
x = -1.5
The x-intercept = (-1.5, 0)
when x = 0
y = 2(0) + 3
y = 3
The y-intercept = (0, 3)
Locate the points (-1.5, 0) and (0, 3) to graph the equation y = 2x + 3
For the equation y = -1/3 x + 2, calculate the x and y intercepts
when y = 0
The x-intercept = (6, 0)
when x = 0
y = -1/3 (0) + 2
y = 2
The y-intercept = (0, 2)
The graphs of the two equations are plotted using their x and y intercepts as shown below
y = 2x + 3 is plotted in red
y = -1/3 x + 2 is plotted in blue
The solution to the system of equations represented by the two lines is (-0.429, 2.143)
0.00067
You always want the period to the right of the first number meaning you’ll start from there counting backwards because it is negative.
