Cameron's current service charge of $0.95 per song, and the new service charge of $0.89 per song and $12 fee for joining, gives;
Formula for finding the number of songs that makes the cost of both services the same is; 0.95•s = 12 + 0.89•sComputing the value of s that satisfies the above equation gives the number of songs at which the cost of both service is the same as 200 songs The interpretation is the the cost of either service is the same when 200 songs are downloadedHow can the equation that gives the required number of songs be found?To Formulate
The charges for songs on the current music service is, C1 = 0.95•s
The charges for the new download service is, C2 = 12 + 0.89•s
Where the $12 is the joining fee
When the cost is the same for both service, we have;
C1 = C2
Which gives;
0.95•s = 12 + 0.89•sThe equation to represent when the cost for both service is the same is therefore;
0.95•s = 12 + 0.89•s
Computing;
The number of songs that gives the same costs is therefore;
0.95•s = 12 + 0.89•s
12 = 0.95•s - 0.89•s = 0.06•s
s = 12 ÷ 0.06 = 200
The number of songs at which the cost of each option will be the same is s = 200 songsInterpreting the solution;
The interpretation is, the cost of songs downloaded on both service will be the same, when 200 songs are downloaded.

82 78 80 72 85 80 calculate the mean and standard deviation of service speed using the formula for each. Show work.
The mean is 79.5.
The standard deviation is 3.99
What is the mean and standard deviation?Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
(82 + 78 + 80 + 72 + 85 + 80) / 6 = 477 / 6 = 79.5
Standard deviation is used to determine how the values in a group differs from the mean of the values in the group.
In order to determine the standard deviation, take the following steps:
Determine the mean of the observation:79.50
Determine the difference between each value and the mean and then square the result: (82 - 79.5)² + (78 - 79.5)² + (80- 79.5)² + (72- 79.5) ²+ (85- 79.5)² + (80- 79.5)² = 6.25 + 2.25 + 0.25 + 56.25 + 30.25 + 0.25 = 95.5

7x - 2y = 1

Substitution method Linear Equations
The value of 'x' and 'y' is '1' and '3' , respectively.
Substitution method :The substitution method is the algebraic method to solve simultaneous linear equations.
The first step in the substitution method is to find the value of any one of the variables from one equation in terms of the other variable.
Lets solve the given linear equations:
7x − 2y = 1 ... eq. (1)
3x + 4y = 15 ... eq. (2)
By equation 1 we got,
x = (1 + 2y)/7
Now, we will put x = (1 + 2y)/7 in equation 2,
3x + 4y = 15
3 [(1 + 2y)/7] + 4y = 15
3/7 × (1 + 2y) = 15 - 4y
3(1 + 2y) = 7(15 - 4y)
3 + 6y = 105 - 28y
6y + 28y = 105 - 3
34y = 102
y = 102/34
y = 3
Now, put the value y =3 in equation 1,
7x - 2y = 1
7x - (2×3) = 1
7x - 6 = 1
7x = 1 + 6 = 7
7x = 7/7
x = 1
Hence, the value of x is 1 and y is 3.

Consider the polynomials:
A(x) = (3-x)2² - (x-3) (7x+4)-18+2x²
B(x) = (3x + 2)² - (x - 1)²
1) Develop and reduce A (x).
2) Factorize A (x) and B (x).
3) Solve the equation A (x)= B(x)
4) Prove that B (X) -3 = 2x(4x+7) , then solve the equation B(x) =3
Answer:
1) -5x² + 13x + 6
2) B(x) =(4x + 1 )(2x + 3)
A(x) = (5x +2)(3-x)
Step-by-step explanation:
1) Expand the equation by using distributive property. Then simplify by combining the like terms.
A(x) = (3 -x)2² - (x -3)(7x+ 4) - 18 + 2x²
= (3 - x)4 - [x*7x + x*4 - 3*7x - 3*4] - 18 + 2x²
= 3*4 - x*4 - [7x² + 4x - 21x - 12] - 18 + 2x²
= 12 - 4x - 7x² - 4x + 21x + 12 - 18 + 2x²
= 2x² - 7x² -4x - 4x + 21x + 12 + 12 - 18
= -5x² + 13x + 6
B(x) = (3x + 2)² - (x - 1)²
Identities:
(a + b)² = a² + 2ab + b² ; Here a =3x & b = 2
(m -n)² = m² - 2mn + n² ; Here m = x & n = 1
2) B(x) = (3x)² + 2*3x*2 + 2² - [x² - 2*x*1 + 1]
= 9x² + 12x + 4 - [x² - 2x + 1]
= 9x² + 12x + 4 - x²+ 2x - 1
= 9x² - x² + 12x + 2x + 4 - 1
= 8x² + 14x +3
Product = 8*3 = 24
Sum = 14
Factors = 2 , 12 {2*12 = 24 & 2 +12= 14}
= 8x² + 2x + 12x + 3 {Rewrite the middle term}
= 2x(4x + 1) + 3(4x + 1)
= (4x + 1 )(2x + 3)
A(x) = - 5x² + 13x + 6
= -5x² + 15x -2x + 6
= 5x(-x +3) +2 (-x + 3)
= (5x +2)(3-x)
4) B(x) - 3 = 8x² + 14x + 3 - 3
= 8x² + 14x
= 2x *4x + 2x *7
=2x(4x + 7)
Hence proved.
B(x) = 3
8x² + 14x + 3 = 3
8x² + 14x + 3 - 3 = 0
8x² + 14x = 0
2x(4x + 7) = 0

A sidewalk that is 2 ft wide surrounds a rectangle that is 4 ft by 6 ft what's the area of the sidewalk in square feet
The area of a sidewalk that surrounds a rectangle of 4 ft by 6 ft is 56 ft²
The given situation can be depicted in the attached picture.
Recall the formula to calculate the area of a rectangle:
A = l ⨉ w
Where:
l = length
w = wide
In the attached picture, the area of the sidewalk is the one with green color.
Notice that:
Area of sidewalk = area of bigger rectangle – area of smaller rectangle
Parameters of the bigger rectangle:
l = 6 + 2 + 2 = 10 ft.
w = 4 + 2 + 2 = 8 ft.
Area of bigger rectangle = 10 x 8 = 80 ft²
Parameters of the smaller rectangle:
l = 6 ft.
w = 4 ft.
Area of bigger rectangle = 6 x 4 = 24 ft²
Hence,
Area of sidewalk = 80 - 24 = 56 ft²

The company must produce 25 t-shirts to break even.
Here, we are given that a company producing t-shirts charges $125 for the design and set up plus $5 per tee.
This means-
fixed cost of producing the t-shirts = $125
Variable cost of producing a t-shirt = $5
Let x be the number of t-shirts produced
Thus, the total cost of producing t-shirts will be-
Total cost = 125 + 5x
Further, the selling price of 1 t-shirt = $10
Thus, selling price of x t-shirts = $10x
Now, at the break even point, the profit is 0, this implies-
Selling price = cost price
⇒ 10x = 125 + 5x
10x - 5x = 125

he first step in simplifying the expression: (1.8 x 10^5) - (2.6 x 10^3)
a
Addition and subtraction requires the terms to be "like terms" with the same power of the base 10, so you would need to change the second number to (0.026 x 10^5).
b
Addition and subtraction do not require any changes, so you would just subtract (2.6 - 1.8) and (10^(5-3))
c
Addition and subtraction do not require any changes, so you would just subtract (1.8 - 2.6) and (10^(5-3))
d
Addition and subtraction requires the terms to be "like terms" with the same power of the base 10, so you would need to change the second number to (2600 x 10^5).
Using scientific notation, the first step in simplifying the expression is given by:
a. Addition and subtraction requires the terms to be "like terms" with the same power of the base 10, so you would need to change the second number to (0.026 x 10^5).
What is scientific notation?A number in scientific notation is given by:
[tex]a \times 10^b[/tex]
With the base being [tex]a \in [1, 10)[/tex].
For two numbers in scientific notation to be added or subtracted, they need to have the same exponent, which removes options b and c.
Moving the second number for 10^3 to 10^5 would be equivalent to a multiplication by 100, hence we have to divide by 100 at the base, that is:
2.6 x 10^3 = (2.6/100) x 10^5 = 0.026 x 10^5.
Hence option a is correct.

What was the total distance that Mr. Carter traveled
from his boat to where he ended up?
Answer:
he traveled 900 feet
Step-by-step explanation:
250 + 650 = 900
Mr. Carter traveled a total distance of 900 feet from his boat to where he ended up.
Here, we have to find the total distance that Mr. Carter traveled from his boat to where he ended up, we need to calculate the sum of the distances above and below sea level.
The distance above sea level is 250 feet (his house boat's level), and the distance below sea level is 650 feet (where he ended up after jumping).
Total distance traveled = Distance above sea level + Distance below sea level
Total distance traveled = 250 feet + 650 feet
Total distance traveled = 900 feet
Mr. Carter traveled a total distance of 900 feet from his boat to where he ended up.
