Think of f(x) as y, because it is the same thing so find the x for your domain
Answer:
The cost per square inch of the pie is $0.111 or 11 cents
Step-by-step explanation:
The shape of a pie is circular.
The area of a circle (pie) = πr²
From the question ,
Diameter = 12 inches
Radius = Diameter/2
Radius = 12 inches/2
Radius = 6 inches.
Hence, the area of the pie = π × 6²
= 113.09733553 square inches
A pie costs $12.55
The cost per square inches of the pie is calculated as:
113.09733553 square inches = $12.55
1 square inch = $x
Cross Multiply
113.09733553x = $12.55
x = $12.55/113.09733553
x = $0.1109663631
Approximately
x = $0.111
Therefore, the cost per square inch of the pie is $0.111 or 11 cents
x = 375 and y = 6300. Option C.
Step-by-step explanation:
From the given data we need to find the value of x and y.
First, we will find out the ratio of area and the force.
= 
So,
or, x = 
= 375
Again,
or, y = 420×15 = 6300
Hence,
x = 375 and y = 6300.
Answer:
Growth 119
Step-by-step explanation:
It is positive and the percentage is 1.19 with the decimal moved 2 places to to the right.
Answer:
8200/1000 = 8.2 so each time a class selss 8.2 bars, they receive 1 dollar.
If a class sold 16 bars, the class receives 2 dollars, if it sold 82 bars, it receives 10 dollars and so on.
