Set up all of them up as a fraction x/y where x is the fluid ounces and y is the cost.
Next, find the values of all the fractions and note them down.
Brand Z had the highest cost per fluid ounce of 2, and therefore is the correct answer.
Answer:

Step-by-step explanation:
First thing you want to do is divide your fluid ounces by your given cost. Which ever is greatest is your answer.
Brand w: 20/12.00 = 1.66
Brand x: 15/11.25 = 1.33

What is system linear equation?
An equation for a line is known as a linear equation. alternatively, y + 0.5x 3.5 = 0 and others. (Note that each linear equation is the same.) When multiple linear equations interact, we get a system of linear equations.
Here the given system linear equations,
[tex]3y=\frac{3}{2}x+6[/tex] -------> 1 and [tex]\frac{1}{2}y-\frac{1}{4}x=3[/tex] --------> 2
Divide by 3 of equation 1 on both sides then,
[tex]y=\frac{1}{2}x+2[/tex] -----------> 3
Now put 3 into 2 then,

A person rides a Ferris wheel that turns with constant angular velocity. Her weight is 520.0 N. At the top of the ride her apparent weight is 1.5N different from her true weight. (a) Is her apparent weight at the top 521.5N or 518.5N Why? (b) What is her apparent weight at the bottom of the ride? (c) If the angular speed of the Ferris wheel is what is its radius?
Answers
(a) At the top of the ride, her apparent weight is 518.5 N. This is because, at the top of the ride, the centripetal force acting on her is directed towards the center of the Ferris wheel, which acts in opposition to her weight. Since her weight is 520 N, and the centripetal force is 1.5 N, the net force acting on her is 518.5 N.
Apparent weight, also known as effective weight or net weight, is the weight that an object appears to have when it is in motion. It is the force that an object feels as a result of a combination of its true weight and any additional forces acting on it, such as the centripetal force.
(b) At the bottom of the ride, her apparent weight is 520.5 N. This is because, at the bottom of the ride, the centripetal force acting on her is in the same direction as her weight, so the net force acting on her is the sum of her weight and the centripetal force.
(c) The radius of the Ferris wheel can be determined using the formula v^2 = r * g, where v is the angular velocity, r is the radius and g is the acceleration due to gravity. Given that angular speed and the apparent weight is known, you can use this formula to find the radius.

The statement that is true about the ratios comparing the width and length of each painting is:
The paintings' width to length ratios are equal because the ratio 4 to 6 is equal to the ratio 2 to 3.
Ratio of numbers.A ratio is a fraction which compares the values of two numbers. Such that they can be expressed as a ratio of one to the other. Example is the ratio of a to b which can be expressed as; a:b or a/ b.
From the first dimension of the canvas size, we have;
length = 6 feet
width = 4 feet
So that,
the ratio comparing the width and length = 4/ 6
= 0.6667
From the second dimensions of the canvas size, we have;
length = 3 feet
width = 2 feet
the ratio comparing the width and length = 2/ 3
= 0.6667
Therefore, the statement that is true about the ratios comparing the width and length of each panting is; The paintings' width to length ratios are equal because the ratio 4 to 6 is equal to the ratio 2 to 3.

The vertex is (5,-9)
The vertex, what is it?A vertex is a point on a polygon where two rays or line segments meet, the sides, or the edges of the object come together. Vertex is the plural form of vertices.
The function is given as f(x) = (x - 8) (x - 2)
Taking the parentheses out
f(x) = x2 - 2x - 8x + 16
f(x) = x2 - 10x + 16
The function's vertex is (h, k)
h = -b / 2a
Changing the values
h = - (-10) / 2 (1) (1)
h = 10 / 2
the x coordinate for h = 5
changing the quadratic function's x value

[tex]\text{c)} \quad y=5(2)^x[/tex]

Step-by-step explanation:
[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Function}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]
Part (c)Given points:
(2, 20)(7, 640)Substitute the given (x, y) points into the exponential function formula to create two equations:
[tex]\implies 20=ab^2[/tex]
[tex]\implies 640=ab^7[/tex]
Divide the second equation by the first equation to eliminate a:
[tex]\implies \dfrac{640}{20}=\dfrac{ab^7}{ab^2}[/tex]
[tex]\implies 32=\dfrac{b^7}{b^2}[/tex]
Solve for b:
[tex]\implies 32=b^7 \cdot b^{-2}[/tex]
[tex]\implies 32=b^{7-2}[/tex]
[tex]\implies 32=b^5[/tex]
[tex]\implies b=2[/tex]
Substitute the found value of b into one of the equations and solve for a:
[tex]\implies 20=a \cdot 2^2[/tex]
[tex]\implies 20=4a[/tex]
[tex]\implies a=5[/tex]
Substitute the found values of a and b into the exponential function formula:
[tex]\implies y=5(2)^x[/tex]
---------------------------------------------------------------------------------------
Part (d)Given points:
(0, 6)(3, 48)As a is the y-intercept, a = 6.
Substitute the point (3, 48) and the found value of a into the exponential function formula and solve for b:
[tex]\implies 48=6b^3[/tex]
[tex]\implies 8=b^3[/tex]
[tex]\implies b=2[/tex]
Substitute the found values of a and b into the exponential function formula:
[tex]\implies y=6(2)^x[/tex]
---------------------------------------------------------------------------------------
Part (e)Given points:
(1, 21)(2, 147)Substitute the given (x, y) points into the exponential function formula to create two equations:
[tex]\implies 21=ab^1[/tex]
[tex]\implies 147=ab^2[/tex]
Divide the second equation by the first equation to eliminate a:
[tex]\implies \dfrac{147}{21}=\dfrac{ab^2}{ab^1}[/tex]
[tex]\implies 7=\dfrac{b^2}{b^1}[/tex]
Solve for b:
[tex]\implies 7=b^2 \cdot b^{-1}[/tex]
[tex]\implies 7=b^{2-1}[/tex]
[tex]\implies 7=b^1[/tex]
[tex]\implies b=7[/tex]
Substitute the found value of b into one of the equations and solve for a:

What is precision?In Mathematics, precision can be defined as a quality which is independent of accuracy because it only describes how close together are numerical values that are obtained in a series of measurements.
What is the greatest possible error (GPE)?In Mathematics, the greatest possible error (GPE) of a measurement can be defined as one-half of the value of a given smallest measuring unit, or one-half of a given precision.
This ultimately implies that, the greatest possible error (GPE) of a measurement can calculated by dividing the precision by two and this is represented by this mathematical expression;
Greatest possible error (GPE) = precision/2
Greatest possible error (GPE) = 4700/2

Arithmetic is a branch of mathematics that deals with the manipulation of numbers and the properties of operations such as addition, subtraction, multiplication, and division. It is often referred to as "elementary mathematics" or "number theory" and is one of the oldest and most basic branches of mathematics.
If 5/7 of the runners at the festival are women, we can use this information to find how many runners are women.
Let's call the number of women runners W. We know that 5/7 of the runners are women, so we can set up the following proportion:
W / 1050 = 5/7
To find the value of W, we can cross-multiply and then solve for W:
W * 7 = 5 * 1050
W = 750
Hence, there are 750 women runners at the festival out of 1050 runners.

Answers
The Fourier series coefficients for T-2 and A-4 are Ao = 2, B(n-odd) = 0, and B(n-even) = -(4/nπ). The Fourier series for the function is then given by:Y(t) = A0 + ΣB(n)cos(nπt/T) + ΣB(n)
The Fourier series coefficients are used to determine the Fourier series of a given function. The Fourier series is an infinite series of sines and cosines which, when summed, gives an approximation of the original function.
The coefficients are determined by integrating the function over a period and solving for the coefficient of each term.
The coefficients for the function T-2 and A-4 are determined by first calculating the period of the function. The period of the function is T=4. The coefficients are then calculated by integrating the function from 0 to T and solving for each coefficient. The coefficients for T-2 and A-4 are then calculated as follows:
A0= 2
B(n-odd) = 0

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be represented as P
The coordinates of point P = P ( 12 , 11 )
Now , the point P movers 8 units left
So , the new coordinates of the position is ( 12 - 8 , 11 )
The new coordinates is ( 4 , 11 )
And , the it moves 7 units down ,
So , the coordinates of the point Q be Q ( 4 , 11 - 7 )
On simplifying , we get
The coordinates of point Q = Q ( 4 , 4 )
Hence , the coordinate is Q ( 4 , 4 )
