Answer:On three of the percentage points you improved your average score.
Step-by-step explanation:I hope this helps.
Answer:
75 + 85 + 90 + 90 + 100 + 75 + 80 + 100 + 90 = 785
785/9 = 87.2
85 + 85 + 100 + 90 + 100 + 85 + 80 + 100 + 90 = 815
815/9 = 90.5
90.5 - 87.2 = 3.3
Round 3.3 to the nearest percent = 3%

For the given system of inequalities, x represents the number of brownies and y the number of cookies.
And the graph can be seen in the image below.
What each variable represents?Here we have the system of inequalities:
4x + 6y ≥ 200
x + y < 75.
We know that they want to make less than 75 items, that is what the second inequality:
x + y < 75.
Represents.
We also know that each brownie costs $4, and each cookie costs $6, then the expression:
x*4 + y*6
Represents the revenue for selling x brownies and y cookies, and because they want to earn at least $200, the inequality becomes:
x*4 + y*6 ≥ 200
So we conclude that x represents the number of brownies and y the number of cookies.
Now the system is:
4x + 6y ≥ 200
x + y < 75.
To graph it, you just need to graph both the lines and shade the indicated region, we can write the inequalities sa:
y ≥ (200 - 4x)/6
y < 75 + x
Just graph these two lines, for the first one you need to use a solid line and shade the region above the line, for the second, a dashed line and you need to shade the region below the line. The graph can be seen below.
The solutions to the systems are in the region where both shaded parts intersect.
There we can see that the point x = 20 and y = 20 (among a lot of other ones) is a solution to the system.

the total is equal to the sum of the principal and interest.
According to the above statement,
Given,
Jeweler's 36-inch silver chain is available.
She needs five times as much, or 5 x 36, to make some necklaces.
To create some bracelets, she will require three times that much,
3×36

can someone derive f(x) = x using first principles method. Like I know the answer is 1 and can do it by power rule but i cannot get that answer for the life of me using first principles method.
fyi first principles function is in the pic
Answers
The derivation by definition of f(x) = x, that is, f'(x) = 1, is found in this problem.
How to find the derivative of function f(x) by the definition?The derivative is given by:
[tex]f^{\prime}(x) = \lim_{h \rightarrow 0} \frac{f(x + h) - f(x)}{h}[/tex]
For this problem, we have that:
f(x) = x.f(x + h) = x + h.Hence:
[tex]f^{\prime}(x) = \lim_{h \rightarrow 0} \frac{x + h - x}{h}[/tex]
[tex]f^{\prime}(x) = \lim_{h \rightarrow 0} \frac{h}{h}[/tex]
[tex]f^{\prime}(x) = \lim_{h \rightarrow 0} 1[/tex]
The limit of a constant is the constant, hence f'(x) = 1.

Answers
Given that Point F is on line segment EG, the Length of segment EF is 4.
What is the numerical length of segment EF?A line segment is simply part of the line that connects 2 points.
Given the data in the question;
Point F is on line segment EGSegment EG = 12Segment FG = 8Length of segment EFSince Point F is on line segment EG, length of segment EG equals the sum of length of segment EF and length of segment FG.
Length of segment EG = Length of segment EF + Length of segment FG
Hence;
12 = Length of segment EF + 8
Subtract 8 from both sides and simplify
12 - 8 = Length of segment EF + 8 - 8
12 - 8 = Length of segment EF
4 = Length of segment EF
Length of segment EF = 4
Given that Point F is on line segment EG, the Length of segment EF is 4.

Painted Cubes
Imagine that we paint a 4 x 4 x 4 cube blue on every side.
How many of the small cubes have 3 blue faces?
How many have 2 blue faces?
How many have 1 blue face?
How many faces would be painted in a cube of any size?
How many have not been painted at all?
Answers
If we paint a 4 x 4 x 4 cube blue on every side then we will get 8 small cubes having 3 blue faces, 16 cubes having 2 blue faces, 24 cubes with 1 blue face, 6 faces would be painted in a cube of any size and 8 cubes have not been painted at all.
Elaborate the answer that is obtained above.Corner cubes are the only ones with 3 faces, whereas a cube has 8 corners. There are therefore 8 cubes with 3 blue faces.
Each of the 16 cubes has 2 blue faces. These are the cubes found between the sides' corners.
The 4 center cubes have only 1 side painted. Because each side has six sides and four center cubes, 6 x 4 = 24. As a result, 24 cubes have 1 blue face.
Because a cube has 6 faces, every size cube will have at least 6 colored faces.
On the inside of the larger cube, there are exactly 8 cubes. As a result, 8 cubes have been left unpainted.

We are given a linear function:
f(x) = 2 x + 3
We are also given the domain of the function as:
Domain = (-4, 5)
We need to find the range of the function and draw its graph.
For x = -4, the value of function will be:
f( -4) = 2 (-4) + 3
f( -4) = - 8 + 3
f( -4) = - 5
For x = 5, the value of function will be:
f( 5) = 2 (5) + 3
f( 5) = 10 + 3
f( 5) = 13
So, the range will become:
( -5, 13)
The graph of the function with points:

2/5a - 3/4b =c solve for a
Answers
The equation (2/5)*a - (3/4)*b = c solved for the variable a is:
a = (5/2)*(c + (3/4)*b)
How to solve the equation for a?Here we have the equation:
(2/5)*a - (3/4)*b = c
Where a, b, and c are variables.
Here we want to solve this equation for the variable a, this means that we need to isolate that variable in one side of the equation, so let's do that.
First, we need to remove the other term, then we can add its opposite in both sides of the equation so we get:
(2/5)*a - (3/4)*b + (3/4)*b = c + (3/4)*b
(2/5)*a = c + (3/4)*b
Now we need to remove the factor that multiplies the variable, we can do that by multiplying both sides of the equation by its inverse, whic is 5/2, if we do that we will get:
(5/2)*(2/5)*a = (5/2)*(c + (3/4)*b)
a = (5/2)*(c + (3/4)*b)
This is the equation solved for the variable a.

What is Target marketing?A target market is a group of people identified as the most likely potential customers for a product because of their shared characteristics such as age, income, and lifestyle. Identifying the target market is a vital part of the decision-making process when a company designs, packages, and advertises its product.
What Are the 4 Target Markets?Marketing professionals divide consumers into four major segments:
Demographic: These are the main characteristics that define your target market. Everyone can be identified as belonging to a specific age group, income level, gender, occupation, and education level.
Geographic: This segment is increasingly relevant in the era of globalization. Regional preferences need to be taken into account.
Psychographic: This segment goes beyond the basics of demographics to consider lifestyle, attitudes, interests, and values.
Behavioral: This is the one segment that relies on research into the decisions of a company's current customers. New products may be introduced based on research into the proven appeal of past products.

A Corresponding Angles Postulate
B. Alternate Interior Angles Theorem
c. Consecutive Interior Angles Theorem
D. Alternate Exterior Angles Theorem
Answers
If P||Q and T is a transversal, then ∠1=∠5 can be justified through Corresponding angle postulate. Thus, correct option is option A.
The Corresponding angle postulate states that if two lines are drawn on plane which are parallel to each other and dissected by a line passing through them at any angle then the corresponding angle of both the parallel lines will be equal to each other and hence would be congruent.
Here, P||Q and P and Q are dissected by the line T at some angle therefore to prove that ∠1=∠5 we go by the following steps:
∠4=∠5 as they are alternate interior angles.
and ∠1=∠4 as they are vertically opposite angles.
Thus, ∠1=∠5 and they are corresponding angles.
