I am sure about this answer because I had this in my syllabus last year.
Answer:
Vtotal = (vol of prism) + (1/2)(vol of cylinder)
volume of prism = 9×10×11 = 990 in^3
volume of cylinder = pi×(5in)^2×(9in)
= 225pi in^3
Therefore, the total volume is
Vtotal = 990 in^3 + (1/2)(225pi in^3)
= 1343.4 in^3

Find the measure of the exterior angle
Answer:
Exterior angle = 75 degrees
Step-by-step :
180 - (2x + 15) = (adjacent angle to the exterior angle. Linear pair)
180 - 2x - 15 + 45 + x = 180 (interior angles of a triangle)
-2x + 30 + x = 180 - 180
-x + 30 = 0
30 = x
Exterior angle: 2(30) + 15 = 75 degrees
Answer:
The measure of the exterior angle is 75°Step-by-step explanation:
We know that:
45 + x + (180 - 2x + 15) = 180Work:
45 + x + (180 - 2x - 15) = 180=> 45 + x + 180 - 2x - 15 = 180=> 210 - x = 180=> 210 - 180 = x=> 30 = xNow, let's substitute the value of x into the expression.
2(30) + 15=> 60 + 15=> 75Hence, the measure of the exterior angle is 75°

Hi, I am having trouble determining how to calculate the average cost per unit? Any help is greatly appreciated.
Kubin Company's relevant range of production is $16,000 to 24,500. When it produces 20,250units, it's average cost s per unit are as follows (see attached).
1) For Financial Accounting purposes, what is the total amount of product costs incurred to make 24,500 units?
2) what is the total amount of period costs incurred to sell 16,000 units?
Step-by-step explanation:]
Answer:
The total amount of product costs incurred to make 24,500 units is $208,250.
The total amount of period costs incurred to sell 16,000 units is $81,750.
Step-by-step explanation:
To determine the total amount of product costs incurred to make 24,500 units, we need to multiply the average cost per unit by the number of units produced. Since the average cost per unit is $8.50, the total product costs incurred to make 24,500 units would be:
$8.50 x 24,500 = $208,250
To determine the total amount of period costs incurred to sell 16,000 units, we need to use the information provided for the relevant range of production. The relevant range of production is $16,000 to 24,500. The period costs are fixed costs that do not change with the level of production. Since the period costs are not dependent on the level of production, the total amount of period costs incurred to sell 16,000 units would be the same as selling 24,500 units. To find the total period costs, we need to subtract the product costs from the total costs.
Total Costs = $290,000 (from the attached sheet)
Product costs = $208,250 (calculated above)
Period costs = Total Costs - Product costs = $290,000 - $208,250 = $81,750
The total amount of period costs incurred to sell 16,000 units is $81,750.

There were toy cars,dolls and teddy bears in a shop. 30% of the toys were toy cars. The ratio of the number of dolls to the number of teddy bears were 4:1 . There were 156 more dolls than you cars. After some toy cars were sold, 16% of the remaining toys in the shop was toy cars. How many toy cars were left in the shop?
Answer:
80 toy cars were left in the shop.
Step-by-step explanation:
Since there were toy cars, dolls and teddy bears in a shop, and 30% of the toys were toy cars, and the ratio of the number of dolls to the number of teddy bears were 4: 1, and there were 156 more dolls than toy cars, and after some toy cars were sold, 16% of the remaining toys in the shop were toy cars, to determine how many toy cars were left in the shop the following calculation must be performed:
Toy cars = 30%
Dolls and teddy bears = 70%
70/5 = 14 x 4 = 56
Dolls = 56%
Teddy bears = 14%
56 - 30 = 26
156/26 = 6 (1%)
Toy cars = 30 x 6 = 180
Dolls = 56 x 6 = 336
Teddy bears = 84
100 - 16 = 84
84 = 336 + 84 = 420
16 = X
84 = 420
16 = X
16 x 420/84 = X
80 = X
Therefore, 80 toy cars were left in the shop.

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.

The area of the shaded which is obtained using the composite figure formed the shaded region and the area under the curve of the specified function is; (2·π - 3·√3)/2 square units
What is a composite figure?A composite figure is one that is composed of two or more simpler figures.
The area can be considered of comprising of a composite figure of the area under the curve of the function and the area of the shaded region
The function representing the curve under the shaded region can be presented as follows;
y = 3·cos(x) + 1
The interval specified under the curve can be expressed as follows;
0 ≤ x ≤ π/3
Therefore, the area under the curve can be found as follows;
\(\int\limits^\frac{\pi}{3} _3 {3\cdot cos(x) + 1} \, dx = [3\cdot sin(x) + x]^{\frac{\pi}{3} }_0 = 3\cdot sin(\frac{\pi}{3} ) + \frac{\pi}{3} - 0 = 3\cdot sin(\frac{\pi}{3} ) + \frac{\pi}{3}\)
sin(π/3) = (√3)/2
Therefore; 3·sin(π/3) + π/3 = 3·(√3)/2 + π/3 = (2·π + 9·√3)/6
The area of the rectangle = (4 - 0) × (π/3 - 0) = 4·π/3
The area of the shaded region = Area of the rectangle - Area under the curve of the specified function
Therefore, area of the shaded region = 4·π/3 - (2·π + 9·√3)/6 = (2·π - 3·√3)/2

The value of x in the polygon will be 13.25 degrees.
The value of x is 10.
We can find the value of x by plugging in the number of sides of the regular polygon into the formula x = (n-2)*15° - 1.
How to calculate the valueThe sum of the interior angles of a regular polygon with n sides is (n-2) x 180 degrees.
Sum of angles = (24-2) x 180 = 22 x 180 = 3960 degrees
Since all the angles in a regular polygon are congruent, we can divide the sum of the angles by the number of angles to find the measure of one angle:
Measure of one angle = 3960/24 = 165 degrees
165 = 12x + 6
159 = 12x
x = 13.25
Therefore, the value of x is 13.25 degrees.
Each of the triangles in our decomposition has one angle equal to (17x+2)°, so the sum of all the angles in the triangles is 43 × (17x+2)° = 731x+86°.
Therefore, we have:
731x+86° = 7380°
Solving for x, we get:
731x = 7294°
x = 10
Therefore, the value of x is 10.
The equation that can be used to find the value of x is:
(9x+48)° + (15x-24)° = (n-2)*180°
24x + 24 = (n-2)*180°
Dividing both sides by 24, we get:
x + 1 = (n-2)*15°
Subtracting 1 from both sides, we get:
x = (n-2)*15° - 1

you are sent to the local tea shop to pick up 9 drinks. You purchase 3 sweet teas and 6 unsweetened teas. Unfortunately, you forgot to label them. If you pick 3 drinks at random, find the probability of each event below. Give your answers as simplified fractions.
The probability of the four events are: Event 1: 1/84Event 2: 3/14Event 3: 15/28 Event 4: 5/21
The total number of drinks = 9The number of sweet teas = 3The number of unsweetened teas = 6If you select 3 drinks at random, the following events can take place:
Event 1: All three drinks are sweet teas. The probability of event 1 = (Number of ways in which all three drinks can be sweet teas) / (Number of ways to select 3 drinks)The number of ways in which all three drinks can be sweet teas = 3C3 = 1 (because all three sweet teas are already fixed)The number of ways to select 3 drinks = 9C3 = (9 × 8 × 7)/(3 × 2 × 1) = 84Therefore, the probability of event 1 = 1/84 = 1/84
Event 2: Exactly two drinks are sweet teas. The probability of event 2 = (Number of ways in which two drinks are sweet teas and one is an unsweetened tea) / (Number of ways to select 3 drinks)The number of ways in which two drinks are sweet teas and one is an unsweetened tea = (3C2 × 6C1) = 18 (because you can choose 2 sweet teas from 3 and 1 unsweetened tea from 6)The number of ways to select 3 drinks = 9C3 = (9 × 8 × 7)/(3 × 2 × 1) = 84Therefore, the probability of event 2 = 18/84 = 3/14
Event 3: Exactly one drink is a sweet tea. The probability of event 3 = (Number of ways in which one drink is a sweet tea and the other two are unsweetened teas) / (Number of ways to select 3 drinks)The number of ways in which one drink is a sweet tea and the other two are unsweetened teas = (3C1 × 6C2) = 45 (because you can choose 1 sweet tea from 3 and 2 unsweetened teas from 6)The number of ways to select 3 drinks = 9C3 = (9 × 8 × 7)/(3 × 2 × 1) = 84Therefore, the probability of event 3 = 45/84 = 15/28
Event 4: All three drinks are unsweetened teas. The probability of event 4 = (Number of ways in which all three drinks can be unsweetened teas) / (Number of ways to select 3 drinks)The number of ways in which all three drinks can be unsweetened teas = 6C3 = 20 (because you can choose 3 unsweetened teas from 6)The number of ways to select 3 drinks = 9C3 = (9 × 8 × 7)/(3 × 2 × 1) = 84 Therefore, the probability of event 4 = 20/84 = 5/21

Anna volunteers on the weekend at the Central Library. As a school project, she decides to record how many people visit the library, and where they go. On Saturday, 382 people went to The Youth Wing, 461 people went to Social Issues, and 355 went to Fiction and Literature. On Sunday, the library had 800 total visitors. Based on what Anna had recorded on Saturday, about how many people should be expected to go to The Youth Wing? Round your answer to the nearest whole number.
Based on the data recorded by Anna on Saturday, we can estimate the number of people expected to visit The Youth Wing on Sunday.
Let's calculate the proportion of visitors to The Youth Wing compared to the total number of visitors on Saturday:
\(\displaystyle \text{Proportion} = \frac{\text{Visitors to The Youth Wing on Saturday}}{\text{Total visitors on Saturday}} = \frac{382}{382 + 461 + 355}\)
Next, we'll apply this proportion to the total number of visitors on Sunday to estimate the number of people expected to go to The Youth Wing:
\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} = \text{Proportion} \times \text{Total visitors on Sunday}\)
Now, let's substitute the values into the equation and calculate the estimated number of visitors to The Youth Wing on Sunday:
\(\displaystyle \text{Proportion} = \frac{382}{382 + 461 + 355}\)
\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} = \text{Proportion} \times 800\)
Calculating the proportion:
\(\displaystyle \text{Proportion} = \frac{382}{382 + 461 + 355} = \frac{382}{1198}\)
Calculating the estimated number of visitors to The Youth Wing on Sunday:
\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} = \frac{382}{1198} \times 800\)
Simplifying the equation:
\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} \approx \frac{382 \times 800}{1198}\)
Now, let's calculate the approximate number of visitors to The Youth Wing on Sunday:
\(\displaystyle \text{Expected visitors to The Youth Wing on Sunday} \approx 254\)
Therefore, based on the data recorded on Saturday, we can estimate that around 254 people should be expected to go to The Youth Wing on Sunday.

suppose a person in the club with 91 members transfers to the club with 71 memebers. A student claims that the measures of center and the measures of spread will change. Correct the students error
Answer:
It is an incorrect claim from the student that the measures of central tendency will change.
It is a correct claim from the student that the measures of spread will change but only range and standard deviation.
Step-by-step explanation:
The complete question is: Suppose a person in the club with 91 members transfers to the club with 71 members. A student claims that the measures of centers and the measures of spread will all change. Correct the student’s error.
Data set was: 80, 74, 77, 71, 75, and 91.
Firstly, we have to represent the original data set in ascending order;
Original data set = 71, 74, 75, 77, 80, and 91.
Now, it is stated that a person in the club with 91 members transfers to the club with 71 members, so the new data set is;
New data set = 72, 74, 75, 77, 80, and 90.
Now, first taking into account the measure of central tendency that is; Mean and Median.
Mean of both the data will remain the same because there is no change in the sum of all values in both the data set, i.e;
Mean of original data = \(\frac{71+74+75+77+80+91}{6}\)
= \(\frac{468}{6}\) = 78
Mean of new data = \(\frac{72+74+75+77+80+90}{6}\)
= \(\frac{468}{6}\) = 78
Now, the median of both the data set will also remain the same because there is a change in the first and last term of the data, so there will be no effect on the middle value in both the data.
Hence, it is an incorrect claim from the student that the measures of central tendency will change.
Now, taking into account the measure of spread that is; Range, Inter-quartile range, and Standard deviation.
Range is given by = Highest value - Lowest value
So, the range of original data = 91 - 71 = 20
and the range of new data = 90 - 72 = 18
This means that the range of data has been changed.
Now, the inter-quartile range = Second last term - Second term of data
So, the inter-quartile range of original data = 80 - 74 = 6
and the inter-quartile range of new data = 80 - 74 = 6
This means that the inter-quartile range of data has not been changed.
Now, the standard deviation = \(\sqrt{\frac{\sum (X - \bar X)^{2} }{n-1} }\)
So, the standard deviation of the original data = \(\sqrt{\frac{(71-78)^{2} +.......+ (91-78)^{2} }{6-1} }\)
= 7.043
The standard deviation of the new data = \(\sqrt{\frac{(72-78)^{2} +.......+ (90-78)^{2} }{6-1} }\)
= 6.481
This means that the standard deviation has been decreased.

86n + 13 ≤ 99 or n + 90 ≥ 97
Does anybody know the answer?
Answer:
n ≤ 1 or n ≥ 7
Step-by-step explanation:
solve each part separately
86n + 13 ≤ 99 ( subtract 13 from both sides )
86n ≤ 86 ( divide both sides by 86 )
n ≤ 1
n + 90 ≥ 97 ( subtract 90 from both sides )
n ≥ 7
solution is n ≤ 1 or n ≥ 7
how can you use pythagora's theorem to solve problems involving right-angled triangles
Using Pythagorean theorem, the length of the ladder is 10ft
What is Pythagorean Theorem?In mathematical terms, if y and z are the lengths of the two shorter sides (also known as the legs) of a right triangle, and x is the length of the hypotenuse, the Pythagorean theorem can be expressed as:
x² = y² + z²
In the questions given, the only one we can use Pythagorean theorem to solve is the one with ladder since it's forms a right-angle triangle.
To calculate the length of the ladder, we can write the formula as;
x² = 8² + 6²
x² = 64 + 36
x² = 100
x = √100
x = 10
The length of the ladder is 10 feet
