Given :
Total apartments 1044 .
Increase in apartments , 8.1 % .
To Find :
How many apartments were there in Baldwin County last year.
Solution :
Let , amount of apartments last year is x .
So ,
[tex]\dfrac{1044-x}{x}\times 100=8.1\\\\(1044-x)\times 100=8.1x\\\\104400-100x=8.1x\\\\108.1x=104400\\\\x=\dfrac{104400}{108.1}\\\\x=965[/tex]
Hence , this is the required solution .

Zoey signed up for a streaming music service that costs $7 per month. The service allows Zoey to listen to unlimited music, but if she wants to download songs for offline listening, the service charges $0.75 per song. How much total money would Zoey have to pay in a month in which she downloaded 45 songs? How much would she have to pay if she downloaded ss songs?
The total money would Zoey have to pay in a month in which she downloaded 45 songs will be $40.75. And she has to pay if she downloaded s songs that will be y = 0.75s + 7.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Zoey signed up for a streaming music service that costs $7 per month. The service allows Zoey to listen to unlimited music, but if she wants to download songs for offline listening, the service charges $0.75 per song.
Let x be the number of songs and y be the total amount. Then the equation will be
y = 0.75x + 7
The total money would Zoey have to pay in a month in which she downloaded 45 songs will be
y = 0.75 × 45 + 7
y = 33.75 + 7

For each equation, state whether there is no solution, one solution, or infinitely many solution. Explain your reasoning. A: 3x - 6 = 3(x - 1) - 3 B: 2x + 7 = - 2x + 7 C: 2x + 7 = 2x
Answer:
A: Infinite
B: One
C: No Solution
Step-by-step explanation:
Equation A:[tex]3x-6=3(x-1)-3\\\\3x-6=3x-3-3\\\\\boxed{3x-6=3x-6}[/tex]The sides are the same. This means that the equation has infinite solutions.
Equation B:[tex]2x+7=-2x+7\\\\2x+7-7=-2x+7-7\\\\2x=-2x\\\\2x+2x=-2x+2x\\\\4x=0\\\\\frac{4x=0}{4}\\\\\boxed{x=0}[/tex]The equation has one solution.
Equation C:[tex]2x+7=2x\\\\2x-2x+7=2x-2x\\\\\boxed{7\neq 0}[/tex]

A resort hotel in Scottsdale, AZ charges $1800 to rent a reception hall, plus $58 per person for dinner and open bar. The reception hall can accommodate up to 200 people. a) Write a function, T, to represent the total cost to rent the reception hall if n people attend the reception.
Answer:
T(n) = 1800 + 58n
Step-by-step explanation:
Rent reception = $1800
Charge per person = $58
Number of person who attend reception = n
Total cost = fixed cost + variable cost
Fixed cost = 1800
Variable cost = 58n
Total cost = T(n)
Total cost = fixed cost + variable cost
T(n) = 1800 + 58n
1/2 (n – 4) – 7 = -2n+6
Answer:
n = 6
Step-by-step explanation:
Simplify [tex]\frac{1}{2}[/tex] · [tex](n-4)-7[/tex]
n/2 -2 -7 =-2n +6
n/2 - 9+ -2n +6
Move all terms containing n to the left side of the equation.
n/2 - 9 +2n =6
To write 2
n as a fraction with a common denominator, multiply by
n/2 + 2n *(2/2) -9 = 6
combine 2n and (2/2)
n/2 + (2n*2)/2 -9 = 6
Combine the numerators over the common denominator.
(n+2n*2)/2 - 9 = 6
Simplify each term.
(n(1+2*2))/2 - 9 = 6
(n(1+4))/2 -9 = 6
(n*5)/ 2 - 9 = 6
5n/2 - 9 =6
Move all terms not containing n to the right side of the equation.
Add 9 to both sides of the equation.
5n/2 = 6 + 9
5n/2 = 15
Multiply both sides of the equation by 2/5
2/5 * 5n/2 = 2/5 *15
Simplify both sides of the equation.
2/5 * 5n/2
Cancel the common factor of 2
Cancel the common factor of 5
n = 2/5 *15
Cancel the common factor of 5
n = 2 * 3
Multiply
n = 6

If B is the midpoint of AC, and AC=8x-20, find BC.
Answer:
[tex]BC=26[/tex]
Step-by-step explanation:
Start with:
[tex]AB+BC=AC[/tex]
Since [tex]B[/tex] is the midpoint, we also know that:
[tex]AB=BC[/tex]
Knowing this, we can use a system of equations and substitute [tex]AB[/tex] for [tex]BC[/tex] in the equation we started with:
[tex]AB+AB=AC[/tex]
Let's identify our values:
[tex]AB=3x-1\\AC=8x-20[/tex]
Substitute:
[tex]3x-1+3x-1=8x-20[/tex]
Combine like terms:
[tex]6x-2=8x-20[/tex]
Add [tex]20[/tex] to both sides of the equation:
[tex]6x+18=8x[/tex]
Subtract [tex]6x[/tex] from both sides of the equation:
[tex]18=2x[/tex]
Divide by the coefficient of [tex]x[/tex], which is [tex]2.[/tex]
[tex]x=9[/tex]
Substitute [tex]9[/tex] into [tex]3x-1[/tex]
[tex]3(9)-1[/tex]
Solve:
[tex]AB=26[/tex]
Remember that [tex]AB=BC[/tex], thus:
[tex]BC=26[/tex]

9. If H is the midpoint of GI, find GH.
5x + 2
9x - 10
FIND GH
I inserted the graph
Answer:
GH = 17
Step-by-step explanation:
Given that H is the midpoint of segment GI, and GH = 5x + 2, HI = 9x - 10, GH is congruent to HI. This implies GH = HI.
Therefore:
[tex] GH = HI [/tex], which will give us the following equation:
[tex] 5x + 2 = 9x - 10 [/tex]
Solve for x
[tex] 5x + 2 - 9x = 9x - 10 - 9x [/tex] (subtracting 9x from each side)
[tex] -4x + 2 = -10 [/tex]
[tex] -4x + 2 - 2 = -10 - 2 [/tex] (subtracting 2 from each side)
[tex] -4x = -12 [/tex]
[tex] \frac{-4x}{-4} = \frac{-12}{-4} [/tex] (dividing both sides by -4)
[tex] x = 3 [/tex]
GH = 5x + 2
Plug in the value of x
GH = 5(3) + 2 = 15 + 2
GH = 17

The area of the star shaped surface of this block is 1.2m^2. The thickness of the block is 25cm. What is the volume of the block?
Answer:
volume = 0.30 m³
Step-by-step explanation:
GIVEN:
The area of the star shaped surface of this block is 1.2m^2.
The thickness of the block is 25cm.
FIND:
What is the volume of the block?
SOLUTION:
volume = area x length
where area = 1.2 m²; length = 0.25 m
plugin values into the formula:
volume = 1.2 m² x 0.25 m
= 0.30 m³
therefore, the volume of the star shaped block is 0.30 m³
how do you find the equation of a line
If m/8 =57, find m/1.
Answer:
696
Step-by-step explanation:
[tex]\frac{m}{8} = 87[/tex]
First I would multiply each side by 8 to find what M is (because if you multiple m/8 by 8 the 8s will cancel out).
[tex]m=87*8\\m = 696[/tex]
Because any number divided by 1 would just be itself, 696/1 is just 696.
Answer: m/1= 7.125 or 7.1 (rounded)
Step-by-step explanation:
if m/8=57 then m/1 multiplied by 8 would be 57 . so you do the opposite and divide 57 by 8.
Mr. mehta is trying to subtracting one polynomial from another polynomial, what must he do first?
The first thing he has to do is take that "minus" sign through the parentheses containing the second polynomial. Some students find it helpful to put a " 1 " in front of the parentheses, to help them keep track of the minus sign. Here's what the subtraction looks like, when working horizontally.
