Answer:
A
Step-by-step explanation:
-19-11 = -19 + (-11)
All Real Numbers that are NOT Rational Numbers; cannot be expressed as
fractions, only non-repeating, non-terminating decimals
−√2 , −√5 3 , √21, √81 3 , √101
*Even roots (such as square roots) that don’t simplify to whole numbers are irrational.
The shape is a square, therefore, all sides are equal.
The edge of the circle touches the edge of the square, and thus, one side of the square can be considered to be the same length as the diameter of the circle.
The formula for circumference is :
2"pie"r
Perimeter = 40ft.
Therefore each side = 10ft.
Therefore diameter = 10ft.
Therefore radius = d/2 = 10/2 = 5 ft.
Therefore circumference = 2"pie"5 ft = 10"pie" ft
(don't forget the unit of measurement!)

Step-by-step explanation:
Model:
s = slices
x = pizzas ordered
s = .8(.45x) + .12(.55x)
Now plugin 20 for x and you will get the total number of slices.
s = .8(.45x) + .12(.55x)
s = .8(.45(20)) + .12(.55(20))
s = 204 slices
Note, we could make this model different and smaller but I chose this method because it demonstrates what is going on with the word problem
