Answer:

Step-by-step explanation:

Since it is given that when two lines intersect, the angle on the top left is 53° and 127°, thus they both form supplementary angles  as the sum of both angles that is 53+127=180°.

Also, from the given information, the angle on the top is 34° and on the bottom is 56°, they both form a complementary angle pair, a sthe sum of both the two angles is 90° as 56+34=90°.

Also, the angle on the top left is =67° and the angle on the bottom right =67°, they both form vertical pair angles as both the angles are vertically opposite to each other.

The length of a side of a rectangle is 2 units less than a number, and the width is 4 units more than the length. Which of the following expressions represents the area of the rectangle, in square units?

Answers

Let's find the expressions for the length and width of the rectangle. The length (which we will call l) is 2 units less than some undefined number, thus we will use the variable x:
l = x - 2

The width is 4 more than this length:
w = l + 4 = (x - 2) + 4 = x + 2

Now, given that we have the length and width and are looking for the area, we need to multiply these expressions together.

One way to write this would simply be (x + 2)(x - 2). If we wanted to find a different way of writing the area, we could use FOIL to find all terms and get x^2 - 4.

12x+5y-3z=36
x-2y+4z=3
9x-10y+5z=27
inconsistent and dependent
consistent and dependent
consistent and independent
inconsistent and independent

Answers

Answer: These three planes are consistent and independent.

Explanation:

Since,  if the system of planes has a solution then it is  called Consistent, While, if it does not have any solution then it is called inconsistent.

Further, If the consistent system has infinite solution then it is dependent but if it has only a unique solution then it is called independent.

Here, given equations of planes are

12x+5y-3z=36           -------(1 )

x-2y+4z=3                 -------(2)

9x-10y+5z=27          -------(3)

From equation (1), 3z=12x+5y-36⇒z=4x+5y/3-12   ------(4)

after putting this value in equation (2) and (3), we will get two equation in variables x and y

So, x-2y+4(4x+5y/3-12)=3 ⇒x-2y+16x+20y/3-48=3⇒3x-6y+48x+20y-144=9⇒51x+14y=153   --------(5)

And, 9x-10y+5(4x+5y/3-12)=27⇒ 9x-10y+20x+25y/3-60=27⇒ 27x-30y+60x+25y-180=81⇒87x-5y=261   --------(6)

after solving equation equation (5) and (6) we will get x=3 and y=0

substituting these values in equation (4) we will get z=0

Thus the solution of these three plane (1), (2) and (3) is x=3, y=0 and z=o

Which is the unique solution, Thus the given planes are consistent and independent.



The given system of equations is consistent and independent so, [tex]\fbox{\begin\\\ \bf option (3)\\\end{minispace}}[/tex] is correct.

Further explanation:

A system of equations is said to be a consistent system if the solution exists and if the solution does not exist then it is an inconsistent system.  

If a consistent system has a unique solution then it is an independent system of equations but if the number of solutions is infinite then it is a dependent system of equations.

Label the given equations as shown below:

[tex]\boxed{x-2y+4z=3}[/tex]               …… (1)

[tex]\boxed{12x+5y-3z=36}[/tex]         …… (2)

[tex]\boxed{9x-10y+5z=27}[/tex]         …… (3)

The augmented matrix for the above equations is, as follows:

Now, apply row transformation [tex]R_{2}\rightarrow R_{2}-4R_{3}[/tex] and [tex]R_{3}\rightarrow R_{3}-3R_{2}[/tex] as,

[tex]\left[\begin{array}{ccc}1&-2&4\\0&-3&73\\0&-1&188\end{array}\Biggm\vert\begin{array}{c}3\\0\\0\end{array}\right][/tex]  

Now, apply row transformations [tex]R_{2}\rightarrow -R_{2}+2R_{3}[/tex] and [tex]R_{3}\rightarrow R_{3}+R_{2}[/tex] as,

[tex]\left[\begin{array}{ccc}1&-2&4\\0&1&303\\0&0&491\end{array}\Biggm\vert\begin{array}{c}3\\0\\0\end{array}\right][/tex]  

The equations obtained from the above augmented matrix are,

[tex]\begin{aligned}x-2y+4z&=3\\y+303z&=0\\491z&=0\end{aligned}[/tex]  

The first equation is simplified to obtain the value of z as,

[tex]\begin{aligned}491z&=0\\z&=0\end{aligned}[/tex]  

Substitute [tex]0[/tex] for [tex]z[/tex] in the equation [tex]y+303z=0[/tex]  to obtain the value of [tex]y[/tex] as,

[tex]\begin{aligned}y+(303\cdot0)&=0\\y&=0\end{aligned}[/tex]

Now, substitute [tex]0[/tex] for [tex]z[/tex] and [tex]0[/tex] for [tex]y[/tex] in the equation [tex]x-2y+4z=3[/tex] to obtain the value of [tex]x[/tex] as,

[tex]\begin{aligned}x-(2\cdot0)+(4\cdot0)&=3\\x&=3\end{aligned}[/tex]  

Therefore, the value of [tex]x[/tex] is [tex]3[/tex], the value of [tex]y[/tex] is [tex]0[/tex] and the value of [tex]z[/tex] is [tex]0[/tex] and the system has a unique solution.

Thus, the given system of equations is consistent and independent.

Option (1)

Here, the first option is inconsistent and dependent.

There exists a solution of the given system of equations so it is consistent.

Therefore, option (1) is incorrect.

Option (2)

Here, the second option is consistent and dependent.

There exists a solution of the given system of equations so it is consistent.

Also, the solution is unique therefore the system of equations is independent.

Therefore, option (2) is incorrect.

Option (3)

Here, the third option is consistent and independent.

There exists a solution of the given system of equations so it is consistent.

Also, the solution is unique therefore the system of equations is independent.

Therefore, option (3) is correct.

Option (4)

Here, the fourth option is inconsistent and independent.

There exists a solution of the given system of equations so it is consistent.

Therefore, option (4) is incorrect.

Greg drew a pair of parallel lines and a line segment next to each other on a chalkboard. Which of these statements best compares the pair of parallel lines and the line segment? (1 point) Parallel lines and the line segment have no dimensions of measurement. The parallel lines and the line segment always meet at a common endpoint which is called the vertex. Parallel lines and a line segment cannot lie on the same plane at the same time because they do not overlap. The parallel lines extend infinitely in both directions, and the line segment has two endpoints.

Answers

The parallel lines extend infinitely in both directions, and the line segment has two endpoints.

Answer: If drew drew a pair of lines and draw the segment between them, in a way that the segment is delimited by both lines, then:

If two lines are parallel, then they will never overlap each other, and if you draw a segment between them, then the segment will have two endpoints (one at each intersection with the lines)

So the correct answer is that the parallel lines extend infinitely in both directions, and the line segment has two endpoints.

A field test for a new exam was given to randomly selected seniors. The exams were graded, and the sample mean and sample standard deviation were calculated. Based on the results, the exam creator claims that on the same exam, nine times out of ten, seniors will have an average score within 4% of 70%.

Is the confidence interval at 90%, 95%, or 99%? What is the margin of error? Calculate the confidence interval and explain what it means in terms of the situation.

Answers

All our answers lie in the above statement.

Confidence Level:
The creator claims that 9 out 10 students will have the average score in the said range. Or in other words we can say that the creator is 90% confident about the result of the field test. So the confidence level is 90%. 

Margin of Error:
The average score lies within 4% of 70%. This means the margin of error is 4% i.e. the average scores can deviate from 70% by 4% .

Confidence Interval:
Lower Limit = 70% - 4% = 66%
Upper Limit = 70% + 4% = 74%

Interpretation:
The exam creator is 90% confident that the average scores of seniors will be between 66% and 74%.

 0.25         0.60             0.15                   1

 Answer:
 
The sum of each row in the table makes sense because we are writing the same amount in three different ways.
 
Therefore, the result is the same.

Final answer:

The sums of each row in the table represent allocations of a whole expressed in different formats (fractions, percentages, and decimals), and they all add up to 1 or 100%, signifying a full allocation of resources.

Explanation:

To find the sum of each row in the provided table, we add the numbers given within that row. Since the table is arranged with fractions, percentages, and decimals that all represent proportions of a whole, the sum of each row should theoretically be equal if converted into the same format. For instance, we should expect each row to total 1 or 100% if we are discussing a full allocation of resources like a budget.

For the first row, we need to add the fractions: 1/4 + 6/10 + 3/20. To do this, we'd need a common denominator, which is 20. So we get (5/20) + (12/20) + (3/20) = 20/20, which simplifies to 1.

The second row represents percentages and they need to total 100%: 25% + 60% + 15% = 100%

Finally, the third row lists decimals which should sum up to 1: 0.25 + 0.60 + 0.15 = 1.00

All three rows make sense because they represent different ways of expressing the whole, which is split into portions allocated to Food, Rent, and Transportation.

Answer:

Step-by-step explanation:

24:2=36:3=66:5.5=108:9=180:15

The complete statement is -

24 : 2 = 36 : 3 = 66 : 5.5 = 108 : 9  = 180 : 15

What is a expression? What is a mathematical equation? What are ratios?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

We have the following statement -

24 : 2 = _ : 3 = _ : 5.5 = 108: _ = _ : 15

We have -

24 : 2 = x : 3 = y : 5.5 = 108 : z  = k : 15

We can solve it partly -

24/2 = x/3

x = (24 x 3)/2

x = 36

Now, we have -

36/3 = y/5.5

(36 x 5.5)/3 = y

y = 12 x 5.5

y = 66

Moving further -

66/5.5 = 108/z

z = (108 x 5.5)/66

z = 9

Finally -

(108/9) = (k/15)

k = (108 x 15)/9

k = 12 x 15

k = 180

Therefore, the complete statement is -

24 : 2 = 36 : 3 = 66 : 5.5 = 108 : 9  = 180 : 15

What is 4xy + xy -7x + x?

Answers

Final answer:

The expression 4xy + xy - 7x + x simplifies to 5xy - 6x by combining like terms, specifically combining 4xy and xy to get 5xy, and -7x and x to get -6x.

Explanation:

The expression 4xy + xy - 7x + x can be simplified by combining like terms. The terms 4xy and xy are like terms, as they both have the same variables x and y to the same power. Similarly, the terms -7x and x are like terms because they both contain the variable x to the same power. To simplify, we combine 4xy and xy to get 5xy and combine -7x and x to get -6x. Therefore, the simplified expression is 5xy - 6x.

Steps involved:

The expression is 4xy + xy - 7x + x.

Combine like terms: 4xy + xy = 5xy

Combine like terms: -7x + x = -6x

Therefore, the simplified expression is 5xy - 6x.

Keller boat travels 24mph. find the rate of the river if she can travel 6 mi upstream. in the same amount of time she can go 10 mi downstream.

Answers

Given that Kellen can travel upstream in the same amount of time she travels downstream, the rate of river will be found as follow:
time=(distance)/(speed)
time taken to travel upstream is:
(24+x)/10
Time taken to travel downstream is:
(24-x)/6
given that the time taken to travel upstream and downstream is the same then:
(24+x)/10=(24-x)/6
6(24+x)=10(24-x)
144+6x=240-10x
6x+10x=240-144
16x=96
x=96/16
x=6 mph


The correct answer is:

6 mph.

Explanation:

We will use the formula d = rt for this, where d is distance, r is rate, and t is time.

We know that the time for both distances is the same; this means we want to isolate t in our formula.  To do this, we will cancel r by dividing both sides:
d/r = rt/r
d/r = t

We will write an expression for the time upstream, an expression for the time downstream, and set them equal.

For the time upstream, the distance is 6 and the rate is 24-x; this gives us

[tex]\frac{6}{24-x}[/tex]

For the time downstream, the distance is 10 and the rate is 24+x; this gives us 

[tex]\frac{10}{24+x}[/tex]

Together, these give us the equation

[tex]\frac{6}{24-x}=\frac{10}{24+x}[/tex]

We cross-multiply to solve this:
6(24+x) = 10(24-x)

Using the distributive property, we have
6*24 + 6*x = 10*24 - 10*x
144+6x = 240-10x

Adding 10x to each side,
144+6x+10x = 240-10x+10x
144+16x = 240

Subtract 144 from each side:
144+16x-144 = 240-144
16x = 96

Divide both sides by 16:
16x/16 = 96/16
x = 6

Find the radius and the circumference to the nearest hundredth when d ≈ 3.8 in. Use 3.14 for π.

C=11.93

The radius is approximately 1.9 in and the circumference is approximately 11.94 in, both rounded to the nearest hundredth.

We have,

If we let d be the diameter of a circle, then the radius of the circle, r, is half of the diameter.

Therefore, we can find the radius of the circle by dividing the diameter by 2:

r = d/2

In this problem,

d ≈ 3.8 in, so we have:

r = 3.8/2 = 1.9 in

To find the circumference of the circle, we can use the formula:

C = 2πr

where π is approximately equal to 3.14 and r is the radius we just found. Substituting in the values, we get:

C = 2 x 3.14 x 1.9 ≈ 11.94 in

Therefore,

The radius is approximately 1.9 in and the circumference is approximately 11.94 in, both rounded to the nearest hundredth.

Answers

Final answer:

Alexa exchanges 27 stamps for 8 sugar cubes. To find the length of a sugar cube, we calculate the volume of each cube and then find the cube root of the total volume.

Explanation:

In this scenario, Alexa buys 27 stamps, each with an area of 1 square unit. She exchanges them for 8 sugar cubes, whose total volume is equal to the total area of the stamps. To find the length of a single sugar cube, we need to calculate the volume of each sugar cube and then find the length of one side.

The total area of the stamps is 27 square units.Since each stamp has an area of 1 square unit, the total volume of the sugar cubes is also 27 cubic units.To find the length of a single sugar cube, we need to find the cube root of 27, which is approximately 3.

Therefore, the length of a cube of sugar is approximately 3 units.
