[tex]\frac{2}{8}[/tex] fraction of the apple pie was served.
Two more pieces of the blueberry pie were served than the apple pieces.
Given that,
Both blueberry pie and apple pie were divided into 8 equal parts each.
To compute the fraction in eights of apple pie, we do a multiplication of the current fraction with 8 parts:
1 apple pie=8 pieces of apple pie
1/4 apple pie = [tex]\frac{1}{4}[/tex] * 8 pieces of apple pie = 2 pieces of apple pie.
1 blueberry pie=8 pieces of blueberry pie.
1/2 blueberry pie = [tex]\frac{1}{2}[/tex] * 8 pieces of blueberry pie = 4 pieces of apple pie.
Thus. 1/4 apple pie is 2 pieces out of 8 pieces of apple pie or written as [tex]\frac{2}{8}[/tex] a fraction of apple pie.
And they served blueberry pies are 4 pieces but served apple pies are 2 pieces, thus the count of pieces of blueberry pie is 2 more than the count of pieces of apple pie served.

What is a set of all X values *?.
The domain is actually the set of all "x" values, whereas the range is the set of all "y" values in an ordered pair.
Given,
What is the definition of the word "domain"?
Remember which of the following symbols corresponds to which ordered pair: (x, y).
When analyzing a set of ordered pairs, first list all the x values from the relation to establish the domain.To find the range, list each of the y values from the ordered pairs first.It is sufficient to list repeated values once as long as they fit within the domain or range.A relation cannot be a function unless each x value has a different value for the y value.If an x value has more than one y value connected with it, such as in the relation (4, 1), (4, 2), where the x value of 4 has y values of 1 and 2, a collection of ordered pairs is not a function.
Thus, the connection is referred to as a function if there is only one y value for every x value.

how much work is done when a 100 lb rock is lifted to a height of 3 ft?
A. The work done is 300 ft-lbs when a 100 lb rock is lifted to a height of 3 ft.
To calculate the work done, we can use the formula: Work = force x distance x cos(Ф).In this case, the force is the force of gravity acting on the rock, which can be calculated using the formula:
force = m * g
where m is the mass of the rock and g is the acceleration due to gravity (32.17 ft/s^2).
force = 100 lb * 32.17 ft/s^2 = 3,217 ft-lbs
The distance is the height to which the rock is lifted, which is 3 ft.
The angle of the rock to the vertical is 90 degrees, so cos(90) = 0.
So,
Work = force x distance x cos(theta) = 3,217 ft-lbs * 3 ft * 0 = 300 ft-lbs
So, the work done is 300 ft-lbs.

Consider given equation x₁ + x₂ + x₃ + x₄ = 17,
where x₁ , x₂ , x₃ and x₄ are non-negative integers.
As we know x₁ is the number of ones before the first zero, x₂ the number of ones between the first and the second zero, x₃ the number of ones between the second and the third zero, and x₄ is the number of ones after the third zero.
This means, there is a 1-1 correspondence between the solutions and reorderings of 17 ones and 3 zeros.

32.56 is the expected weight for a bluegill fish that is 11 inches long.
Equation: What is it?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" symbol and terms on both sides must always be present when writing an equation. Equal treatment should be given to each party. Multiple terms, operators, and variables are not required on each side of an equation. Without them, one can still create an equation, such as 5 + 10 = 15. There are no variables in the equation below.
given expression:
In(Weight) = -5.28 + 3.44 In(Length)
So, we have to find 11 inches then
In(weight) = -5.28 + 3.44 x 11
= -5.28 + 37.84

Which amount is closes to the minimum that the student will need to save every month in order to pay off the remaining cost at the end of 12 months?
Answer:
$488.33 monthly savings
Step-by-step explanation:
Parent payment 30% of $21,800 is $6,540.
Subtract all payment from total cost.
21,800−6,540−5,600−3,800=5,680.

How do I find the value of a slope?Typically, a line's slope provides information about the steepness and direction of the line. Finding the difference between the coordinates of the locations will allow you to quickly compute the slope of a straight line connecting two points, (x1,y1) and (x2,y2).

tan θ = Δy/Δx
the solution is -
Considering a line with a slope of -3 and also the point (9, 4), we could use the point-slope form of either a line to find the equation of a line:
y - 4 = -3(x - 9)
y = -3x + 27 + 4
y = -3x + 31
We are given some other point on the line (8, t) we can try substituting it in the equation above:

How is substitution used to determine if an ordered pair is the solution to a system of equations?.
Substitution is a method for solving systems of equations by substituting the values from one equation into the other. To use substitution to determine if an ordered pair is the solution to a system of equations, first solve one of the equations for either x or y.
Then substitute this value into the other equation, and solve for the other variable. If the ordered pair you obtain is also found in both equations, then it is a solution to the system.
Take the equation set as an example.
2x + y = 5
3x – y = 1
To use substitution to determine if (2, 3) is a solution to this system, first solve one of the equations for either x or y:
2x + y = 5 ⇒ y = 5 – 2x
Add this value to the other equation after that:
3x – (5 – 2x) = 1
⇒ 5x = 6
⇒ x = 6/5
Finally, substitute 6/5 back into either equation to find y:
2(6/5) + y = 5
⇒ 12/5 + y = 5
⇒ y = 10/5
⇒ y = 2
Since (6/5, 2) is found in both equations, it is a solution to the system.

How to simplify the exponential expression?The exponential expression for this problem is defined as follows:
[tex]\frac{3^{10} \times (3^7)^{12}}{9^{12}}[/tex]
Applying the power of power rule, we have that:
(3^7)^12 = 3^(7 x 12) = 84.
When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents, hence:
3^10 x 3^84 = 3^94.
For the denominator, we have that:
9^12 = (3²)^12 = 3^24.
When two terms with the same base and different exponents are divided, we keep the base and subtracted the exponents, hence:

Population in this context refers to the total collection of observations associated with a specific study.
For instance, if university students are asked for input on the teaching staff, the latter group will be considered the study's population.
SamplingThe targeted population is used to choose the various sample entities. With this approach, a predetermined number of observations that come from a bigger pool of populations are statistically analyzed.
Different types of sample methodology can be used, including basic random sampling, systematic sampling, cluster sampling, stratified sampling, and more.
