Using relations in a right triangle, it is found that the measure of angle DHG is of 116º.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.In this problem, angle DHG is the sum of measures a and b.
Angle a is adjacent to a side of 33 cm, while the hypotenuse is of 49 cm, hence:
\(\cos{a} = \frac{33}{49}\)
\(a = \arccos{\left(\frac{33}{49}\right)}\)
\(a = 47.66^\circ\)
Angle b is opposite to a side of 39 cm, while the hypotenuse is of 42 cm, hence:
\(\cos{b} = \frac{39}{42}\)
\(b = \arccos{\left(\frac{39}{42}\right)}\)
\(b = 68.21^\circ\)
Then:
a + b = 47.66º + 68.21º = 115.87º
Rounding, the measure of angle DHG is of 116º.

● Blondies are squares with 3 inch sides. ● Brownies are squares with 6 inch sides. ● The tray that displays the blondies and brownies has an area of 648 square inches and is completely full. If she has 4 rows of blondies and 4 rows of brownies, what fraction of the area of the tray, in square inches, is blondies? Show your work.
The fraction of the area of the tray occupied by the blondies is 1/9.
To find the fraction of the area of the tray occupied by blondies, we need to determine the area occupied by the blondies and compare it to the total area of the tray.
Let's calculate the area of each individual blondie:
The blondies are squares with 3-inch sides, so the area of each blondie is 3 inches × 3 inches = 9 square inches.
Now, let's calculate the area occupied by the blondies in each row:
Since there are 4 rows of blondies and each row contains 4 blondies, the total number of blondies is 4 rows × 4 blondies per row = 16 blondies.
So, the total area occupied by the blondies is 16 blondies × 9 square inches per blondie = 144 square inches.
Next, let's determine the area occupied by the brownies:
The brownies are squares with 6-inch sides, so the area of each brownie is 6 inches × 6 inches = 36 square inches.
Since there are also 4 rows of brownies and each row contains 4 brownies, the total number of brownies is 4 rows × 4 brownies per row = 16 brownies.
Therefore, the total area occupied by the brownies is 16 brownies × 36 square inches per brownie = 576 square inches.
Now, let's calculate the total area of the tray:
Given that the tray is completely full and has an area of 648 square inches, we can subtract the area occupied by the brownies from the total area to find the remaining area occupied by the blondies:
Total area of the tray - Area occupied by the brownies = Area occupied by the blondies
648 square inches - 576 square inches = 72 square inches.
So, the fraction of the area of the tray occupied by the blondies is:
Area occupied by the blondies / Total area of the tray = 72 square inches / 648 square inches.
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 72 in this case:
72 square inches / 648 square inches = 1/9.
Therefore, the blondies' percentage of the tray's surface area is 1/9.

a) The algebraic fraction \(\frac{{x + 2}}{{(x - 1)^2}}\) is proper. b) The algebraic fraction \(\frac{{4x^2 - 31x + 59}}{{(x - 4)^2}}\) can be expressed as \(-\frac{{31}}{{x - 4}} - \frac{{25}}{{(x - 4)^2}}\).
Let's solve each part step by step and determine whether the fraction is proper or improper, and then express it accordingly.
a) \(\frac{{x + 2}}{{(x - 1)^2}}\):
Step 1: Determine the degree of the numerator and the denominator:
- Degree of the numerator = 1 (linear term)
- Degree of the denominator = 2 (quadratic term)
Since the degree of the numerator is less than the degree of the denominator, the fraction is proper.
Step 2: Express the proper fraction in partial fractions:
\(\frac{{x + 2}}{{(x - 1)^2}} = \frac{A}{{x - 1}} + \frac{B}{{(x - 1)^2}}\).
Step 3: Find the values of A and B:
Multiply both sides of the equation by \(((x - 1)^2)\) to eliminate the denominators:
(x + 2) = A(x - 1) + B.
Expand the equation and collect like terms:
x + 2 = Ax - A + B.
Equate the coefficients of like terms:
Coefficient of x: 1 = A.
Constant term: 2 = -A + B.
Solve the system of equations to find the values of A and B:
From the coefficient of x, A = 1.
Substituting A = 1 into the constant term equation: 2 = -1 + B, we find B = 3.
Therefore, the partial fraction decomposition is:
\(\frac{{x + 2}}{{(x - 1)^2}} = \frac{1}{{x - 1}} + \frac{3}{{(x - 1)^2}}\).
b) \(\frac{{4x^2 - 31x + 59}}{{(x - 4)^2}}\):
Step 1: Determine the degree of the numerator and the denominator:
- Degree of the numerator = 2 (quadratic term)
- Degree of the denominator = 2 (quadratic term)
Since the degree of the numerator is equal to the degree of the denominator, the fraction is proper.
Step 2: Express the proper fraction in partial fractions:
\(\frac{{4x^2 - 31x + 59}}{{(x - 4)^2}} = \frac{A}{{x - 4}} + \frac{B}{{(x - 4)^2}}\).
Step 3: Find the values of A and B:
Multiply both sides of the equation by \(((x - 4)^2)\) to eliminate the denominators:
(4x^2 - 31x + 59) = A(x - 4) + B.
Expand the equation and collect like terms:
4x^2 - 31x + 59 = Ax - 4A + B.
Equate the coefficients of like terms:
Coefficient of \(x^2\): 4 = 0 (No \(x^2\) term on the right side).
Coefficient of x: -31 = A.
Constant term: 59 = -4A + B.
Solve the system of equations to find the values of A and B:
From the coefficient of x, A = -31.
Substituting A = -31 into the constant term equation: 59 = 4(31) + B, we find B = -25.
Therefore, the partial fraction decomposition is:
\(\frac{{4x^2 - 31x + 59}}{{(x - 4)^2}} = -\frac{{31}}{{x - 4}} - \frac{{25}}{{(x - 4)^2}}\).
The above steps provide the solution for each part, including determining if the fraction is proper or improper and expressing it in partial fractions.

5. Assume that the $70,000 ending balance in Work in Process includes $24,000 of direct materials. Given this assumption, supply the information missing below:
The unadjusted cost of goods sold for the year is calculated by subtracting the ending inventory from the sum of beginning inventory and purchases. The formula is as follows:
Unadjusted Cost of Goods Sold = Beginning Inventory + Purchases - Ending Inventory
Without knowing the values for beginning inventory, purchases, and ending inventory, we cannot compute the unadjusted cost of goods sold for the year.
5. Given that the $70,000 ending balance in Work in Process includes $24,000 of direct materials, we can calculate the missing information as follows:
Direct Labor = Total Work in Process - Direct Materials - Overhead
Direct Labor = $70,000 - $24,000 - Overhead
Without knowing the value for overhead, we cannot compute the direct labor cost. However, we can rearrange the formula to solve for overhead:
Overhead = Total Work in Process - Direct Materials - Direct Labor
Overhead = $70,000 - $24,000 - Direct Labor
Without knowing the value for direct labor, we cannot compute the overhead cost.

A candle shop sells a variety of different candles. If they are offering a sale for 20% off,
how will this affect the mean, median, and mode cost per type of candle?
Answer:
If a candle shop is offering a 20% off sale, the prices of all candles will be reduced by 20%. This will affect the mean, median, and mode cost per type of candle in the following ways:
Mean: The mean is calculated by adding up all the prices of the candles and dividing by the total number of candles. When the prices are reduced by 20%, the new mean will also decrease by approximately 20%. This is because each price is being multiplied by 0.8, and then the total is divided by the same number of candles.Median: The median is the middle value when all the candle prices are listed in order from lowest to highest. When the prices are reduced by 20%, the relative position of each price will remain the same. However, the actual values will decrease by 20%. Therefore, the new median will also decrease by approximately 20%.Mode: The mode is the most common value in the set of candle prices. When the prices are reduced by 20%, it is possible that the mode will change, depending on the original distribution of prices. For example, if there are originally two or more prices that are tied for the most common value, then the mode may remain the same. However, if there is only one most common value, and this value is reduced by 20%, then a different value may become the new mode.Hope this helps!

b.) State the range of the function.
c.) Identify the end behavior of the function.
d.) Identify the x-intercept. Write as an ordered pair.
e.) Does the function have an absolute maximum? Explain why or why not.
The features of the logarithmic function are given as follows:
a) Domain: x > 0.
b) Range: all real values.
c) End behavior: as x -> ∞, f(x) -> ∞.
d) The x-intercept is at x = 1.
e) The function does not have an absolute maximum, as it is never decreasing.
Features of the functionThe domain of the function is given by the set of input values, hence it is composed by the values of x assumed by the graph.
In this problem, the function is not defined for negative numbers, and has a vertical asymptote at x = 0, meaning that the function is not defined at this point, hence the domain is:
x > 0.
The range is the values of y of the graph, which are the output values of the function. The function assumes all value of y, hence the range is of all real values.
The end behavior of the function is given by the limit when x goes to infinity. The function is only defined for positive numbers, and it increases to right, hence the end behavior is:
As x -> ∞, f(x) -> ∞.
The x-intercept of the function is the value of x at which the function crosses the x-axis, hence it is given by:
x = 1.
An absolute maximum is a point in which the function changes from increasing to decreasing. In this problem, the function is increasing over it's entire domain, hence it contains no absolute maximum.

2tan(x/2)- csc x=0 interval [0,2pi)
Answer:
\(x= \dfrac{\pi}{3}, \;\;x=\dfrac{5 \pi}{3}\)
Step-by-step explanation:
Given trigonometric equation:
\(2 \tan\left(\dfrac{x}{2}\right)- \csc x=0\)
To solve the equation for x in the given interval [0, 2π), first rewrite the equation in terms of sin x and cos x using the following trigonometric identities:
\(\boxed{\begin{minipage}{4cm}\underline{Trigonometric identities}\\\\$\tan \left(\dfrac{\theta}{2}\right)=\dfrac{1-\cos \theta}{\sin \theta}$\\\\\\$\csc \theta = \dfrac{1}{\sin \theta}$\\ \end{minipage}}\)
Therefore:
\(2 \tan\left(\dfrac{x}{2}\right)- \csc x=0\)
\(\implies 2 \left(\dfrac{1-\cos x}{\sin x}\right)- \dfrac{1}{\sin x}=0\)
\(\implies \dfrac{2(1-\cos x)}{\sin x}- \dfrac{1}{\sin x}=0\)
\(\textsf{Apply the fraction rule:\;\;$\dfrac{a}{c}-\dfrac{b}{c}=\dfrac{a-b}{c}$}\)
\(\dfrac{2(1-\cos x)-1}{\sin x}=0\)
Simplify the numerator:
\(\dfrac{1-2\cos x}{\sin x}=0\)
Multiply both sides of the equation by sin x:
\(1-2 \cos x=0\)
Add 2 cos x to both sides of the equation:
\(1=2\cos x\)
Divide both sides of the equation by 2:
\(\cos x=\dfrac{1}{2}\)
Now solve for x.
From inspection of the attached unit circle, we can see that the values of x for which cos x = 1/2 are π/3 and 5π/3. As the cosine function is a periodic function with a period of 2π:
\(x=\dfrac{\pi}{3} +2n\pi,\; x=\dfrac{5\pi}{3} +2n\pi \qquad \textsf{(where $n$ is an integer)}\)
Therefore, the values of x in the given interval [0, 2π), are:

4.
Y
W
3
Given:
In Δ\(WXY,m < Y=90^o,WY=3,XW=5\) and \(YX=4\).
To find:
The ratio represents the cosine of ∠\(W\).
Solution:
In Δ\(WXY,m < Y=90^o\). It means the opposite side of angle Y, i.e., XW is the hypotenuse of the triangle.
In a right angle triangle,
\(cos0=\frac{Base}{Hypotenuse}\)
In the given triangle,
\(cosW=\frac{XY}{YW}\)
\(cosW=\frac{3}{5}\)
Therefore, the required cosine ratio is \(\frac{3}{5}\).
Calculator Triangle ABC is similar totriangle DEF. The length of AC is 12 cm. The length of EF is 35 cm. The length of DF is 20 cm What is the length of BC ? Enter your answer in the box. cm
Answer:
BC = 21 cm
Step-by-step explanation:
In similar triangles the corresponding sides are in same proportion.
Its given in the sum that AC = 12 cm; DF = 20 cm and EF = 35 cm.
\(\sf \dfrac{AB}{DE}=\dfrac{BC}{EF}=\dfrac{AC}{DF}\\\\\\\dfrac{AC}{DF}=\dfrac{BC}{EF}\\\\\dfrac{12}{20}=\dfrac{BC}{35}\)
\(\sf \dfrac{12}{20}*35=BC\\\\\\\dfrac{12}{4}*7=BC\\\\\\3*7=BC\\\\ \boxed{BC = 21 cm}\)
A community would like to add a brick paver border around their swimming pool. They created the following image to represent the pool with the border. A large rectangle with a length of 48 feet and a width of 28 feet. Inside of it is another rectangle with a length of 32 feet and a width of 12 feet. Part A: Find the total area of the brick paver border that surrounds the 12 ft by 32 ft pool. Show your work. (2 points) Part B: If brick pavers cost $8 per square foot, what is the total cost of the brick pavers needed for this project? Explain. (2 points)
Part A: The total area of the brick paver border is \(960\) square feet.
Part B: The total cost of the brick pavers needed for this project is $\(7,680\).
Part A: To find the total area of the brick paver border, we need to subtract the area of the pool from the area of the larger rectangle. The area of the pool is \(32\) feet multiplied by 12 feet, which is equal to \(384\)square feet.
The area of the larger rectangle is \(48\) feet multiplied by \(28\) feet, which is equal to \(1,344\) square feet. Therefore, the area of the brick paver border is \(1,344\) square feet minus \(384\) square feet, which equals \(960\) square feet.
Part B: If brick pavers cost $\(8\)per square foot, we can calculate the total cost by multiplying the cost per square foot by the total area of the brick paver border. The total area of the brick paver border is \(960\) square feet, and the cost per square foot is $\(8\).
Therefore, the total cost of the brick pavers needed for this project is $\(8\)multiplied by \(960\) square feet, which equals $\(7,680\).
Note: The calculations provided assume that the border consists of a single layer of brick pavers.
