Original price of a microphone: $49.99 Discount: 5% Tax: 5%
Answers
First we need to determine what 5% of 49.99 is.
To do this we simply multiply .05 by 49.99.
Why .05 and not .5? Because .5 would be equal to .50 or 50%, which is a lot more than 5%.
This equals, 2.49. Now we first subtract the discount, then add tax. Because you would be subtracting 5% and then adding 5%, in effect they would cancel each other out and you would still be paying 49.99.
49.99 - 2.49 + 2.49 = 49.99

Which of the following systems of inequalities would produce the region indicated on the graph below?
Answers
Answer:
A. y > x+1; y≤10; x≥0
Step-by-step explanation:
Other things being equal, which they are, you're looking for an inequality that has "y >". You know this because shading is above (>) the dashed line (not ≥). Only choice A matches.
__
If the boundary line were solid, you would be looking for "y ≥", since y=(boundary line) is included in the solution set in that case.
The box plots display data collected when two teachers asked their classes how many pencils they lose in a school year.
A box plot uses a number line from 5 to 47 with tick marks every one unit. The box extends from 8 to 14 on the number line. A line in the box is at 11. The lines outside the box end at 7 and 45. The graph is titled Mr. Johnson's Class, and the line is labeled Number Of Pencils.
A box plot uses a number line from 0 to 51 with tick marks every one unit. The box extends from 12 to 21 on the number line. A line in the box is at 14.5. The lines outside the box end at 0 and 50. The graph is titled Mr. Simpson's Class, and the line is labeled Number Of Pencils.
Which class lost the most pencils overall based on the data displayed?
Mr. Simpson's class; it has a larger median value 14.5 pencils
Mr. Johnson's class; it has a larger median of 11 pencils
Mr. Simpson's class; it has a narrow spread in the data
Mr. Johnson's class; it has a wide spread in the data
Answers
Answer:
A) Mr. Simpson's class; it has a larger median value 14.5 pencils.
Step-by-step explanation:
A box plot is a visual display of the five-number summary:
Minimum value = The value at the end of the left whisker.Lower quartile (Q₁) = The left side of the box.Median (Q₂) = The vertical line inside the box.Upper quartile (Q₃) = The right side of the boxMaximum = The value at the end of the right whisker.From inspection of the box plots (attached), the measures of central tendency (median) and dispersion (range and IQR) are:
Mr Johnson's class:
Median = 11IQR = Q₃ - Q₁ = 14 - 8 = 6Range = max - min = 45 - 7 = 38Mr Simpson's class:
Median = 14.5IQR = Q₃ - Q₁ = 21 - 12 = 9Range = max - min = 50 - 0 = 50In a box plot, the median is a measure of central tendency and tells us the location of the middle value in the dataset. It divides the data into two equal halves, with 50% of the values falling below the median and 50% above it.
The median number of pencils lost in Mr Simpson's class is greater than the median number of pencils lost in Mr Johnson's class. Therefore, Mr. Simpson's class has a larger median value.
The spread of data in a dataset can be measured using both the range and the interquartile range (IQR).
As Mr Simpson's class has a greater IQR and range than Mr Johnson's class, the data in Mr Simpson's class is more spread out than in Mr Johnson's class.
In summary, as Mr Simpson's class has a larger median 14.5 and a wider spread of data, then Mr Simpson's class lost the most pencils overall.

Answers
The number of trucks that will be created by the paper depot to deliver 774 cases of toilet paper if each truck loads 18 cases is 43 trucks.
How many trucks will be created?Number of toilet paper a paper depot is delivering = 774 cases
Number of cases a truck will load = 18 cases
Number of trucks that will be created = Number of toilet paper a paper depot is delivering ÷ Number of cases a truck will load
= 774 cases / 18 cases
= 43 trucks
Therefore, 43 trucks are needed by the paper depot to deliver 774 cases of toilet paper at 18 cases per truck.

Answers
Answer:
36
Step-by-step explanation:
75%=0.75
0.75*48=3/4*48=144/4=36
Answer:
75% of 48 is 36.
Step-by-step explanation:
So, what I did here was to first find out what 25% of 48 is, because 75% is 25% multiplied by 3.
50% of 48 = 24
Since 25% is half of 50% all we have to do is divide by 2.
24 ÷ 2 = 12.
Now, we multiply by 3.
12 * 3 = 36
So, the answer is 36.

Differentiate the function.
f(x) = sin(4 ln(x))
Step 1
The function
f(x) = sin(4 ln(x))
is a composition, and so we must use the Chain Rule, given below, to find its derivative.
d
dx
[g(h(x))] = g'(h(x))h'(x)
The "inside" function is
4 ln(x)
and the "outside" function is f(x) =
4cos(4ln(x))
Answers
The derivative of f(x) = sin(4ln(x)) is 4cos(4ln(x)) (1/x).
To apply the Chain Rule, we first need to take the derivative of the "inside" function, which is
4 ln(x).
The derivative of this is
4 (1/x).
Next, we take the derivative of the "outside" function, which is
f(x) = sin(4 ln(x))
The derivative of this is
f'(x) = 4cos(4ln(x)).
Finally, we plug these derivatives into the Chain Rule equation to obtain the derivative of the original function:
d
dx
[f(x)] = 4cos(4ln(x)) (1/x)
Therefore, the derivative of f(x) = sin(4ln(x)) is
d
dx
[f(x)] = 4cos(4ln(x)) (1/x).
The derivative of f(x) = sin(4ln(x)) is 4cos(4ln(x)) (1/x).

Project B: Build a fancy wall on the front side, SR. Project C: Construct paving for a third of the plot. 2.1 Determine the formulae that will be suitable for each of the projects mentioned above. For each formula, also give the reason for your choice. Write down the information in the table attached. Reason Project Formulae A B С (9)
Answers
The sum of the lengths of three sides of the rectangle, gives the length
of the fencing, while one third of the rectangle area is for the pavement.
Responses:
Project A: The formula for the length of the fencing is, L = 4·x - 1
Project B: Length of the fancy wall = 2·x + 1
\(Project \ C:Area \ of \ the \ paving = \underline{ \dfrac{2\cdot x^2 }{3} - \dfrac{x }{3} - \dfrac{1}{3}}\)
Which method can be used to find the length and area of paving from the given equations?
Project A: Let QP and SR represent the longest sides of the rectangle, we have;
PQ = SR = 2·x + 1
Given parameters are;
Length of the rectangular plot = 2·x + 1
Width of the rectangular plot = x - 1
Vertices of the rectangular plot are; QPSR
Project A: Let QP and SR represent the longest sides of the rectangle, we have;
PQ = SR = 2·x + 1
Which gives;
SP = QR = x - 1
The length of the fencing, L = SP + PQ + QR = x - 1 + 2·x + 1 + x - 1 = 4·x - 1
The formula for the length of the fencing is, L = 4·x - 1Project B: The front side is SR
Therefore;
Length of the fancy wall = 2·x + 1Project C:
Area, A = Length × Width
Area of the plot, A = (2·x + 1) × (x - 1) = 2·x² - x - 1
\(Area \ of \ the \ paving = \dfrac{1}{3} \times \left(2 \cdot x^2 - x - 1\right) = \underline{ \dfrac{2\cdot x^2 }{3} - \dfrac{x }{3} - \dfrac{1}{3}}\)

What is the area of this rectangle? Rectangle with width 5.1 cm and height 11.2 cm. Responses 16.3 cm2 16.3 cm, 2 32.6 cm2 32.6 cm, 2 57.12 cm2 57.12 cm, 2 571.2 cm2
Answers
The area of a rectangle with a width of 5.1 cm and a height of 11.2 cm is 57.12 cm².
To find the area of a rectangle, we multiply its length by its width. In this case, the width is given as 5.1 cm and the height (or length) is given as 11.2 cm.
Area = length × width
Area = 11.2 cm × 5.1 cm
Calculating the product, we get:
Area = 57.12 cm²
Therefore, the area of the rectangle is 57.12 cm².
The correct answer is: 57.12 cm².
It is important to note that when calculating the area of a rectangle, we should always include the appropriate unit of measurement (in this case, cm²) to indicate that we are dealing with a two-dimensional measurement. The area represents the amount of space covered by the rectangle's surface.
So, the area of a rectangle with a width of 5.1 cm and a height of 11.2 cm is 57.12 cm².
