Answer:
A; The cost is $0.07 per 
Step-by-step explanation:
In this question, we are asked to calculate the cost of the Chicago pizza per square inch rounded to the nearest cent.
Firstly, we will need to calculate the area occupied by the 14 inch medium pepperoni pizza made by Chicago pizza
Since the pizza is circular in shape, we use the formula for the area of a circle to calculate its area in square inch
Mathematically, the area of a circle is equal to π
. Here, our r is half the size of the pizza as the 14 inch represents the full length of the pizza across the center of the pizza = 7 inch
The area is thus = 22/7 × 7 × 7 = 154
Now, since the full pizza costs $10.49, the cost of the pizza per is 10.49/154 = 0.068 = $0.07 per
Answer:
8
Step-by-step explanation:
To solve this problem, we need to find the area of the pen, then divide that by the area required by each dog.
__
The relationship between circumference and radius is ...
C = 2πr
Solving for r gives ...
r = C/(2π)
The relationship between radius and area of a circle is ...
A = πr²
Substituting for r from above gives ...
A = π(C/(2π))² = C²/(4π)
Filling in the given numbers, we find the area of the pen to be ...
A = (78.5 ft)²/(4·3.14) = 490.625 ft²
__
Dividing the pen area by the area per dog gives the number of dogs the pen can hold:
(490.625 ft²)/(60 ft²/dog) ≈ 8.18 dogs
The pen can safely keep 8 dogs.
Answer:
d
Step-by-step explanation:
5x + 4 = -6
5x= -6-4
5x=-10
x=-2
The value of the first expression is x=-2.
x/2 + 3 = 2
x/2 = 2-3
x/2 = -1
x=-2
The value of the second expression is x=-2.
2x+14=10
2x=-4
x=-2
The value of the third expression is x=-2.
-2=-x
2=x
The value of the fourth expression is x=2.
