A room is an exclusive Dubai hotel costs $× pe4 night. The price then changes to $4370 per night after a decrease of 5% and a increase of 15%. Find ×
Answer:
The value of x is $4000.
Step-by-step explanation:
Let's call x to the original price per night of a room in the Dubai hotel.
The price first decreased by 5%. Calculate 5% of x:
5 * x / 100 = 0.05x
Now subtract it from the original price:
x - 0.05x = 0.95x
This new price is then increases 15%. Calculate 15% of 0.95x:
15 * 0.95x / 100 = 0.1425x
Add it to the previous price:
0.95x + 0.1425x = 1.0925x
This price is equal to $4370, thus:
1.0925x = 4370
x = 4370 / 1.0925
x = 4000
The value of x is $4000.

Answer:
[tex]\frac{13}{4}[/tex] · [tex]\frac{15}{4}[/tex]
Step-by-step explanation:
Focusing on the first fraction, in order to simplify it, you have to multiply the denominator by the whole number; 4 x 3 is 12. You add the product to the numerator, so 12 + 1 would be 13. Therefore, the first fraction simplified would be [tex]\frac{13}{4}[/tex].
We can apply the same procedure to the next fraction, so 3 x 4 is 12, and 12 + 3 is 15. [tex]\frac{15}{4}[/tex] would be your answer.
Hope this helps! :)

What kind of linear relationship can be represented using a table but not a function? Explain. (1 point)
O A horizontal line can be represented using a table but not a function because the slope is undefined
A vertical line can be represented using a table but not a function because the slope is undefined.
O A vertical line can be represented using a table but not a function because the slope is zero.
O A horizontal line can be represented using a table but not a function because the slope is zero
Answer:
The correct option is;
A vertical line can be represented using a table but not a function because the slope is undefined
Step-by-step explanation:
A function, f(x), representing a linear relationship can be presented as follows;
f(x) = m·x + c
Where;
m = The slope = Δy/Δx = (y₂ - y₁)/(x₂ - x₁)
c = The y-intercept
Whereby the line is a vertical line, x₂ = x₁ and x₂ - x₁ =
Therefore;
The slope of a vertical function, m = (y₂ - y₁)/(x₂ - x₁) = (y₂ - y₁)/0 = ∞ from which we have;
f(x) = ∞·x + c = ∞ which is undefined and the vertical line can only be represented using a table but not a function because the slope is undefined

Which of the following ordered pairs is a possible solution to the equation y = 3x - 2?
Answer:
D) (1,1)
Step-by-step explanation:
You can find the solution by plugging the x-value of each coordinate into the equation. It will be a solution if the y-value of the equation equals the y-value of the coordinate.
For example:
y = 3x -2
y = 3(1) - 2
y = 3-2
y = 1
1 = 1
(1, 1) are the coordinates that are on the given line.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given a equation y = 3x -2
To find which coordinates will satisfy the equation:
For coordinates (2, 0)
at x = 2, y should be zero
y = 3 * 2 -2
y = 4
Not satisfied
For coordinates(-3, 0)
at x = -3, y should be 0
y = 3 * -3 - 2
y = -9 -2
y = -11
Not satisfied
For coordinates(0, 2 )
at x = 0, y should be 2
y = 3*0 -2
y = -2
Not satisfied
For coordinates(1, 1)
at x = 1, y should be 1
Y = 3*1 - 2
y = 3 - 2
y = 1
satisfied
Therefore, (1, 1) are the coordinates that are on the given line.

Answer:
There are sixteen 15-cent stamps and eight 20-cent stamps.
Step-by-step explanation:
Stamp collector has:
15c stamps
20c stamps
Total value is $4
x($0.15) + y($0.20) = $4.00
The # of 15c stamps is 8 - than 3 * the # of 20c stamps; 15c = 8 - 3c
x = 3y - 8
(3y-8)(0.15)+y(0.20) = $4.00
0.45)y-1.20+(0.20)y = 4.00
(0.65)y-1.20 = 4.00
(0.65)y = 5.20
y = 8
x = 3(8)-8 = 16
There are sixteen 15-cent stamps and eight 20-cent stamps.

How many liters each of a 45% acid solution and a 70% acid solution must be used to produce 50 liters of a 65% acid solution? (Round to two decimal places if necessary.)
Answer:
The number of liters of the 45% acid solution = 10 liters
The number of liters of the 70% acid solution is = 40 liters
Step-by-step explanation:
How many liters each of a 45% acid solution and a 70% acid solution must be used to produce 50 liters of a 65% acid solution? (Round to two decimal places if necessary.)
Let x be the number of liters of the 45% acid solution
The number of liters of the 70% acid solution is y
x + y = 50
x = 50 - y
Also
How many liters each of a 45% acid solution and a 70% acid solution must be used to produce 50 liters of a 65% acid solution?
We have:
45% × x + 70% × y = 65% × 50
0.45x + 0.70y = 0.65 × 50
0.45x + 0.70y = 32.5
We substitute x = 50 - y in the equation
0.45(50 - y) + 0.70y = 32.5
= 22.5 - 0.45y + 0.70y = 32.5
= - 0.45y + 0.70y = 32.5 - 22.5
= 0.25y = 10
Divide both sides by 0.25
= y = 10/0.25
y = 40 liters
x = 50 - y
x = 50 - 40
x = 10 liters
Hence,
The number of liters of the 45% acid solution = 10 liters
The number of liters of the 70% acid solution is = 40 liters
The function R(x) = -0.0065x² +0.23x + 8.47 models the American marriage rate R (the
number of marriages per 100 population) x years after 1960. Based on this function, in what
year was the marriage rate the highest? (Hint: The vertex of a parabola is the maximum or
minimum.)
please help
Given:
The American marriage rate R, x years after 1960 is defined by the function
[tex]R(x)=-0.0065x^2 +0.23x + 8.47[/tex]
To find:
The year in which the marriage rate is the highest.
Solution:
We have,
[tex]R(x)=-0.0065x^2 +0.23x + 8.47[/tex]
It is a quadratic function with negative leading coefficient. So, it is a downward parabola and vertex of downward parabola is maximum.
If a quadratic function is [tex]f(x)=ax^2+bx+c[/tex], then
[tex]Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)[/tex]
In the given function,
[tex]a=-0.0065,b=0.23,c=8.47[/tex]
Now, x-coordinate of vertex is
[tex]-\dfrac{b}{2a}=-\dfrac{0.23}{2(-0.0065)}[/tex]
[tex]-\dfrac{b}{2a}=-\dfrac{0.23}{-0.013}[/tex]
[tex]-\dfrac{b}{2a}\approx 17.69[/tex]
It means the marriage rate is highest after 17 years of 1960.
[tex]1960+17=1977[/tex]
Therefore, the marriage rate is highest in year 1977.

Tristán wants to build a square garden in his backyard if the garden is going to be 64 ft2 how many feet of material will he need for the perimeter of the garden
Answer:
Tristan will need 32 feet of material for the perimeter of the garden.
Step-by-step explanation:
Given that
Area of square garden = A = 64 square feet
Perimeter = P = ?
We know that for calculation of perimeter, length of side of square is required which is not directly given in the question. The area will be used to calculate length of side and then length will be used to calculate the perimeter.
So,
[tex]Area = A = s^2[/tex]
s is for side
Putting the value of area
[tex]64 = a^2[/tex]
Taking square root on both sides
[tex]\sqrt{s^2} = \sqrt{64}\\s = 8\ feet[/tex]
The length of side is 8 feet.
Perimeter will be:
[tex]P = 4*s\\P = 4*8\\P = 32\ feet[/tex]
Hence,
Tristan will need 32 feet of material for the perimeter of the garden.

Lets make our equation!
2.5 per chore thats our slope
+3 she starts with 3 dollars
y = 2.50x +3
Substitute y for 17!
17 = 2.5x +3
Subtract 3!
14 = 2.5x
Divide both sides by 2.5!
x = 5.6
5.6 --> 6
x = 6
Turn it into an inequality!

Answer:
k = $0.50
Step-by-step explanation:
The data that we have is:
Rocko paid: $12.50 for 25 tickets.
Louisa paid: $17.50 for 35 tickets.
Now, the question asks to find the constant of proportionality.
A proportional relation can be written as:
y = k*x
where k is the constant, and in this case, y is the price and x the number of tickets bought.
Then replacing with the values above, we have:
$12.50 = k*25
then:
k = $12.50/25 = $0.50
And the other data:
$17.50 = k*35
K = $17.50/35 = $0.50
So we have the same k in both cases, this means that the constant of proportionality is k = $0.50
i'm not all too familiar with the constant of proportionality, but both of the situations have a ratio of 0.5/1..
12.50/25 = 0.5/1
17.50/35 = 0.5/1
hopefully this can help you in some way! sorry if it doesn't
