Answers
Answer:
c
Step-by-step explanation:
C is your answer. Since this is a parallelogram, is means that there are two sets of sides with the same length. Because the measurement of angle K is 82 the angle directly opposite would have the same measurement. That's why angle M is also 82. When you add all the angles of a quadrilateral it adds up to 360 degrees. multiply 82 by 2 to get 164 and subtract that from 360 to get 196. you then have to divide that by 2 and you will get 98 which is the measurement for both angles L and N
Answer:
The correct answer is option C.
m<L = 98°, m<M = 82° and m<N = 98°
Step-by-step explanation:
From the figure we can see a parallelogram KLMN
Properties of parallelogram
1)Opposite sides are equal and parallel.
2) Opposite angles are equal.
3) Adjacent angles are supplementary.
To find the correct option
It is given that, m<K = 82°
By using properties of parallelogram we get
m<L = 98°, m<M = 82° and m<N = 98°
Therefore the correct answer is option C

Which statement is true?
All rectangles are squares.
All squares are rectangles.
All quadrilaterals are rectangles.
All parallelograms are rectangles.
Answers
Answer:
B. All squares are rectangles.
Step-by-step explanation:
B is the correct answer, because all the squares are rectangles have 4 sides.
The accurate statement is that all squares are rectangles.
The statement that is true among the options provided is All squares are rectangles. This is because squares have all the properties of a rectangle, which is a quadrilateral with four right angles, but with the additional property of having all four sides of equal length. Therefore, because a square fulfills all the criteria of a rectangle, we can conclude that all squares are indeed rectangles. On the other hand, not all rectangles are squares since rectangles do not require all sides to be equal, only that the opposite sides are equal. Similarly, not all quadrilaterals are rectangles because other quadrilaterals, like rhombuses or kites, do not have the necessary four right angles. Finally, while all rectangles are parallelograms (a quadrilateral with opposite sides that are equal and parallel), not all parallelograms have right angles and thus are not all rectangles.
To elaborate, a rectangle is defined as a parallelogram with right angles. When it comes to comparing areas, the area of a rectangle is calculated by multiplying its base by its height. And in the case of squares, since all sides are equal, it's just the side length squared. However, when you have two shapes with equal area -- for instance, a square and a rectangle -- the one with the longer perimeter would be the one with the less compact shape, which in most cases would be the rectangle unless it is also a square.

A.) Algebraic, common difference = 3
B.) Algebraic, common difference = 6
C.) Geometric, common ratio = 3
D.) Geometric, common ration = 6
Answers
Answer:
Option C.) Geometric, common ratio = 3
Step-by-step explanation:
we know that
In a Geometric Sequence each term is found by multiplying the previous term by a constant
The constant is called the common ratio
In this problem we have
For x=1, f(1)=3
For x=2, f(2)=9
For x=3, f(3)=27
For x=4, f(4)=81
so
f(2)/f(1)=9/3=3 -----> f(2)=3*f(1)
f(3)/f(2)=27/9=3 -----> f(3)=3*f(2)
f(4)/f(3)=81/27=3 -----> f(4)=3*f(3)
f(n+1)/f(n)=3 -----> f(n+1)=3*f(n)
therefore
This is a Geometric sequence and the common ratio is equal to 3
The sequence is a geometric sequence with a common ratio of 3.
Explanation:The sequence given is a geometric sequence. A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio. In this case, the common ratio can be found by dividing a term in the sequence by its preceding term. For example, if we divide the second term (9) by the first term (3), we get 3. The same goes for the rest of the terms in the sequence. Therefore, the correct answer is Option C: Geometric, common ratio = 3.

Answers
Answer:
A(2,2)
Step-by-step explanation:
Let the vertex A has coordinates [tex](x_A,y_A)[/tex]
Vectors AB and AB' are perpendicular, then
[tex]\overrightarrow {AB}=(2-x_A,6-y_A)\\ \\\overrightarrow {AB'}=(-2-x_A,2-y_A)\\ \\\overrightarrow {AB}\perp\overrightarrow {AB'}\Rightarrow \overrightarrow {AB}\cdot \overrightarrow {AB'}=0\Rightarrow (2-x_A)(-2-x_A)+(6-y_A)(2-y_A)=0[/tex]
Vectors AC and AC' are perpendicular, then
[tex]\overrightarrow {AC}=(4-x_A,3-y_A)\\ \\\overrightarrow {AC'}=(1-x_A,4-y_A)\\ \\\overrightarrow {AC}\perp\overrightarrow {AC'}\Rightarrow \overrightarrow {AC}\cdot \overrightarrow {AC'}=0\Rightarrow (4-x_A)(1-x_A)+(3-y_A)(4-y_A)=0[/tex]
Now, solve the system of two equations:
[tex]\left\{\begin{array}{l}(2-x_A)(-2-x_A)+(6-y_A)(2-y_A)=0\\ \\(4-x_A)(1-x_A)+(3-y_A)(4-y_A)=0\end{array}\right.\\ \\\left\{\begin{array}{l}-4-2x_A+2x_A+x_A^2+12-6y_A-2y_A+y^2_A=0\\ \\4-4x_A-x_A+x_A^2+12-3y_A-4y_A+y_A^2=0\end{array}\right.\\ \\\left\{\begin{array}{l}x_A^2+y_A^2-8y_A+8=0\\ \\x_A^2+y_A^2-5x_A-7y_A+16=0\end{array}\right.[/tex]
Subtract these two equations:

Substitute it into the first equation:

Chung has 6 trucks and 5 cars in his toy box. Brian has 4 trucks and 5 cars in his toy box. Which is the correct comparison of their ratios of trucks to cars?
Answers
Final answer:
Chung has a ratio of 6 trucks to 5 cars (6:5), and Brian has a ratio of 4 trucks to 5 cars (4:5). Chung has a higher ratio of trucks to cars compared to Brian.
Explanation:
To compare the ratios of trucks to cars for Chung and Brian, we simply write down the number of trucks and cars each has and form a ratio for each. For Chung, the ratio of trucks to cars is 6 trucks to 5 cars, which can be written as 6:5 or ⅓. For Brian, the ratio of trucks to cars is 4 trucks to 5 cars, or 4:5 or ⅔.
Now, by comparing these two ratios, we see that Chung has a higher ratio of trucks to cars (6:5) compared to Brian (4:5), which means Chung has more trucks relative to cars in his toy box than Brian does.
To compare Chung's and Brian's ratios of trucks to cars, we have to calculate each ratio and then compare them.
**Chung's Ratio:**
Chung has 6 trucks and 5 cars. The ratio of trucks to cars for Chung is the number of trucks divided by the number of cars.
Chung's trucks to cars ratio = Number of trucks / Number of cars
= 6 / 5
**Brian's Ratio:**
Brian has 4 trucks and 5 cars. The ratio of trucks to cars for Brian is the number of trucks divided by the number of cars.
Brian's trucks to cars ratio = Number of trucks / Number of cars
= 4 / 5
Both ratios are to be compared now.
**Comparing Ratios:**
Chung's ratio is 6/5, which is 1.2 when converted into a decimal.
Brian's ratio is 4/5, which is 0.8 when converted into a decimal.
Since 1.2 (Chung's ratio) is greater than 0.8 (Brian's ratio), we can conclude that Chung has a higher ratio of trucks to cars compared to Brian.
Therefore, the correct comparison of their ratios is: "Chung has a higher ratio of trucks to cars than Brian."

Answers
Answer:
In the first week, the number of type-1 cabinets produced was 15, the number of type-2 cabinets produced was 30, the number of type-3 cabinets produced was 65.Step-by-step explanation:
If we let a, b, c represent the numbers of type-1, type-2, and type-3 cabinets produced in the first week, respectively, we can write three equations in these unknowns:
a + b + c = 110 . . . . . total cabinets for the first weeka + 2b - c = 10 . . . . relationship of quantities in the first week3a +0b +c = 110 . . . . total cabinets in the second weekIt can be convenient to let a machine solver find the solution to this set of equations. Most graphing calculators can handle it, along with several web sites.
__
Solving by hand, we can subtract the second equation from twice the first. This gives ...
2(a +b +c) -(a +2b -c) - 2(110) -(10)
a +3c = 210 . . . . simplify
Subtracting this from 3 times the third equation gives ...
3(3a +c) -(a +3c) = 3(110) -(210)
8a = 120 . . . . . simplify
a = 15 . . . . . . . divide by 8
Using this in the third equation of the original set, we have ...
3·15 +c = 110
c = 65 . . . . . . subtract 45
Then, in the first equation, we get ...
15 + b + 65 = 110
b = 30 . . . . . . . subtract 80
The solution is (type-1, type-2, type-3) = (15, 30, 65) for the first week.
The problem provides a set of linear equations. Solving this system by substitution or elimination method will give the number of cabinets of each type produced each week. The equations are formed based on the conditions provided in the problem.
Explanation:From the information provided, we can use a system of equations to solve this. Let's denote the number of type-1 cabinets made in the first week as x , the number of type-2 cabinets as y, and the number of type-3 cabinets as z. The first condition in the problem gives us the equation x + 2y = z + 10. The total number of cabinets produced in each week is 110, so we get the equation x + y + z = 110 for the first week. From the second week's conditions, we know that no type-2 cabinets were made (y=0), the number of type-3 cabinets was the same (z=z) and the number of type-1 cabinets was three times as much as the first week (x=3x), this means 3x + 0 + z = 110.. Solving this system of equations will provide the number of cabinets produced for each type.

When a certain tree was first planted, it was 4 feet tall, and the height of the tree increased by a constant amount each year for the next 6 years. At the end of the 6th year, the tree was 1/5 taller than it was at the end of the 4th year. By how many feet did the height of the tree increase each year?
Answers
Answer:
[tex]\frac{2}{3}\text{ feet}[/tex]
Step-by-step explanation:
Let the equation that models the height of the tree after x years,
y = mx + c
Where, m is constant amount of increasing and c is any constant,
Given,
When x = 0, y = 4,
⇒ 4 = m(0) + c ⇒ c = 4,
Now, the height of plant after 4th year = m(4) + c = 4m + c
Also, the height of plant after 6th year = m(6) + c = 6m + c
According to the question,
6m + c is [tex]\frac{1}{5}[/tex] more than 4m + c,
[tex]6m+c=4m+c + \frac{1}{5}(4m+c)[/tex]
[tex]6m+c = \frac{6}{5}(4m+c)[/tex]
[tex]30m+5c=24m+6c[/tex]
[tex]6m=c[/tex]
By substituting the value of c
6m = 4
⇒ [tex]m=\frac{4}{6}=\frac{2}{3}[/tex]
Hence, 2/3 feet of height is increased each year.

Then the point-slope form of the desired line can be written ...
y = m(x -h) +k . . . . . slope m through point (h, k)
y = 2/3(x +1) +1 . . . . slope 2/3 through point (-1, 1)
y = 2/3x + 5/3 . . . . . . simplify to slope-intercept form
The equation that describes a line through points (-1, 1) and (2, 3) in slope-intercept form is y = 2/3x + 5/3, determined by calculating the slope and y-intercept.
Explanation:The question asks to find the equation in slope-intercept form that describes a line through (-1, 1) and (2, 3). In order to do this, we need to find the slope and y-intercept of the line.
The slope of the line (m) can be determined by using the formula m = [tex](y_2 - y_1) / (x_2 - x_1)[/tex]. Inserting the given points into this formula gives: m = (3 - 1) / (2 - (-1)) = 2 / 3 = 2/3.

What is the next number in the sequence? 9….3….1….1/3…
Answers
The pattern in the sequence 9, 3, 1, 1/3 involves each number being a third of the previous number. Following this rule, the next number after 1/3, obtained by dividing by 3, is 1/9.
Explanation:To determine the next number in the sequence 9, 3, 1, 1/3, we need to identify the pattern or rule that is being followed. Observing the sequence, each subsequent number appears to be a third of the previous number. The first number is 9, and dividing by 3 gives us 3. Dividing the second number, 3, by 3 gives us 1.
Similarly, dividing the third number, 1, by 3 gives us 1/3. Following this logic, to find the next number in the sequence, we divide 1/3 by 3.
Using the arithmetic of division with fractions, we have (1/3) ÷ 3 = (1/3) ÷ (3/1) = 1/9. Therefore, the next number in the sequence is 1/9. We can assume that the rule being applied in this sequence is to divide each number by 3 to find the next number, which aligns with the mathematical pattern identification techniques commonly used.
The next number in the sequence is 1/9.
To find the next number in the sequence 9, 3, 1, 1/3, we need to identify the pattern. This sequence is a geometric sequence where each term is obtained by multiplying the previous term by a common ratio.
Step-by-step:
Start with 9.Multiply it by the common ratio to get the next term.9× (1/3) = 33 ×(1/3) = 11 ×(1/3) = 1/3To find the next term, we continue this pattern:
1/3× (1/3) = 1/9

Given that a sample of employees is selected and it is found that 55 % own a vehicle.
Before we answer the questions let us understand the difference between a parameter and a statistic.
Parameters are numbers that summarizes the data of a population. But statistics are numbers that summarizes the data of a sample.
Sample is a subset of population i.e. a small portion of the whole population is sample.

The smallest number of hot dogs packages and hot dog buns that has the same amount of is the least common multiple between 6 and 8.
6 = 3*2
8 = [tex]2^{3}[/tex]
So, the least common multiple is the product of each multiple with the biggest exponent, that is [tex]2^{3}*3=24[/tex]. Then, Xanthia has to buy 4 hot dog packages to have 24 hotdogs and 24 hotdog buns.
To solve this problem, we first find the least common multiple (LCM) of 6 and 8. 6=2*3 and 8=2^3, so their LCM is 2^3*3=24. Therefore, Xanthia can buy 24÷6=4 hot dog packages and 24÷8=3 hot dog bun packages to have an equal number of hot dogs and hot dog buns. So you have an answer of 4.

There are 81 cars in the CMC parking lot, which are all Acuras, Beetles, or Camrys. There are half as many Acuras as Beetles. The number of Camrys is 80\% of the number of Acuras and Beetles together. How many of the 81 cars are Beetles?
Answers
Answer: 30
Step-by-step explanation:
Let x be the number of Beetles.
Then , the number of Acuras = [tex]\dfrac{1}{2}x[/tex]
Also, The number of Camrys is 80% of the number of Acuras and Beetles together.
Thus , the number of Camrys =[tex]0.8(x+\dfrac{1}{2}x)[/tex]
Now, the total number of cars in parking lot will be :-
[tex]x+\dfrac{1}{2}x+0.8(x+\dfrac{1}{2}x)=81\\\\\Rightarrow\ \dfrac{3x}{2}+0.8(\dfrac{3x}{2})=81\\\\\Rightarrow\ \dfrac{3x+2.4x}{2}=81\\\\\Rightarrow\ 5.4x=2\times81\\\\\Rightarrow\ x=\dfrac{162}{5.4}=30[/tex]
Hence, there are 30 Beetles.

126 sq. ft.
150 sq. ft.
Answers
Answer:
90 sq. ft.
Step-by-step explanation:
To find the "volume," you will need to multiply every the LxWxH.
Length = L
Width = W
Height = H
Then the answer is 90 sq. ft.
Answer:
Surface area = 126 square ft .
Step-by-step explanation:
Given : Rectangular cuboid .
To find : Find the total area of the solid figure.
Solution : We have given Rectangular cuboid .
Length = 3 ft .
Width = 5 ft .
Height = 6 ft .
Surface area = 2 ( l*w + w*h + l *h).
Plug the values
Surface area = 2 ( 3*5 + 5*6 + 3 *6).
Surface area = 2 (15 + 30 + 18).
Surface area = 2 ( 63).
Surface area = 126 square ft .
Therefore, Surface area = 126 square ft .

Answer:
86 because 180 subtract 94 is 86
Answer:
The correct answer is option D. 94 °
Step-by-step explanation:
From the figure we get,
l║ m ║ o and n║ p
To find the measure of <16
It is given that, m<1 = 94°
m<1 + m<4 = 180 [ Same side exterior angles of parallel lines are supplementary]
m<4 = 180 - m<1 = 180 - 94 = 86°
Similarly, m<4 + m<16 = 180
m<16 = 180 - m<4 = 180 - 86 = 94°
The correct answer is option D. 94 °
What is the approximate length of arc s on the circle below? Use 3.14 for pi. Round your answer to the nearest tenth.
A. 5.6 in.
B. 6.3 in.
C. 14.3 in.
D. 25.1 in.
Answers
Answer:
B 6.3
Step-by-step explanation:
r = 8
l = 2*3.14*r
l = 50.24
s=l/360*45
s≈6.3
For this case we have that by definition, the arc length is given by:
[tex]Al = 2 \pi * r *\frac {a} {360}[/tex]
Where:
r: It's the radio
a: It is the angle of the sector
Then, according to the data we have:
[tex]Al = 2 \pi * 8 * \frac {45} {360}\\Al = 2 * 3.14 * 8 * \frac {45} {360}\\Al = 50.24 * \frac {45} {360}\\Al = 6.28[/tex]
Rounding we have 6.3in

A sample of 4 different calculators is randomly selected from a group containing 17 that are defective and 37that have no defects. What is the probability that at least one of the calculators is defective?
Answers
Answer: 0.8025
Step-by-step explanation:
Given : The number of defective calculators : 17
The number of calculators are not defective : 37
Total calculators : 37+17=54
The probability of the calculators are defective : [tex]\dfrac{17}{54}=\dfrac{1}{3}[/tex]
Binomial distribution formula :-
[tex]P(x)=^nC_xp^x(1-p)^{n-x}[/tex], where P(x) is the probability of success in x trials, n is total trials and p is the probability of success for one trial.
The probability that at least one of the calculators is defective is given by :-
[tex]P(x\geq1)=1-P(0)\\\=1-(^4C_0(\dfrac{1}{3})^0(1-\dfrac{1}{3})^4)\\\\=1-(\dfrac{2}{3})^4=0.80246913\approx0.8025[/tex]
