The reason for this has to do with finding the area of a square. When you are looking for the area of a square, you use the rectangle formula (since a square is also a rectangle).
The formula is Area = Length * Width
However, since in a square, the length and width are the same, both get changed to the word "Side". As a result, we get the following formula.
Area = Side * Side
This can be simplified to:
Area = Side^2.
Since each number to the second power also shows the area of a square with that given length sides, it can also be called "squared".
Following are the calculation to the given equation:

Answer:
Equation is = 5+1.75m
Step-by-step explanation:
Given that,
A taxi service charge is $5.00 for each fare.
In addition, the service charges a $1.75 per minute fee.
It means, for every minute, $1.75 increases with time and $5.00 is fixed.
ATQ,
Total cost = 5+1.75m
Where m is time in minutes
Hence, the required equation is "5+1.75m".
The relationship of arcs is:
S '/ S = ((2/5) * pi * r) / (2 * pi * r)
Rewriting we have:
S '/ S = ((2/5)) / (2)
S '/ S = 2/10
S '/ S = 1/5
Therefore, the area of the shaded region is:
A '= (S' / S) * A
Where A: area of the complete circle:
A '= (1/5) * 100 * pi
A '= 20 * pi
Answer:
The area of the shaded region is:
A '= 20 * pi
Answer: the number of minutes of local calls that you made is 644
the number of minutes of international calls that you made is 208
Step-by-step explanation:
Let x represent the number of minutes of local calls that you made.
Let y represent the number of minutes of international calls that you made.
It cost $.06 per local call and $0.15 per international call you are charged $69.84. This means that
0.06x + 0.15y = 69.84 - - - - - - - - 1
The total number of calls add up to 852 minutes. This means that
x + y = 852
Substituting x = 852 - y into equation 1, it becomes
0.06(852 - y) + 0.15y = 69.84
51.12 - 0.06y + 0.15y = 69.84
- 0.06y + 0.15y = 69.84 - 51.12
0.09y = 18.72
y = 18.72/0.09 = 208
x = 852 - y = 852 - 208
x = 644
