Answer:
The value of x that makes m || n is x = 20
Step-by-step explanation:
Given a line that is intersected by another two lines (for example line ''m'' and line ''n'' like in the exercise) one of the conditions that makes m || n is that the alternate interior angles must be congruent. Understanding that congruent means the same.
In the exercise, one pair of alternate interior angles are (2x+20)° and 3x°.
We need this two angles to be congruent ⇒ [tex]3x=2x+20[/tex]
Solving this for ''x'' :
[tex]3x=2x+20\\3x-2x=20\\x=20[/tex]
The value of x that makes 3x° congruent to 2x+20° (that makes the alternate interior angles congruents) is x = 20
Answer:
20
Step-by-step explanation:
Theorem:
If two lines are cut by a transversal such that alternate interior angles are congruent, then the lines are parallel.
Lines m and n are cut by a transversal.
Angles 3x and 2x + 20 are alternate interior angles.
For lines m and n to be parallel, angles 3x and 2x + 20 must be congruent, so their measures must be equal.
3x = 2x + 20
x = 20
Answer: 20
For the values a = 3.4 and b = 2.6, which are legs of a right triangle, find c, the hypotenuse, to the nearest tenth.
hypotenuse = c
c^2 = 3.4^2 + 2.6^2
c^2 = 11.56 + 6.76
c^2 = 18.32
c = sqrt(18.32) = 4.28
rounded to nearest tenth = 4.3

describe how you could estimate thw IQR of the data set from a histogram
Answer: Once you put the numbers in order and find the median do the same process that you did to find the median to the left and right side of the median. Once you find the " median " of the left and right sides ( which are called the 1st and 3rd Quartiles ) You will subtract the 1st quartile from the 3rd Quartile and that will give you the IQR.

City A and City B had two different temperatures on a particular day. On that day, four times the temperature of City A was 8° C more than 3 times the temperature of City B. The temperature of City A minus twice the temperature of City B was −3° C. What was the temperature of City A and City B on that day?
Your answer:
City A was 5° C, and City B was 4° C.
City A was 3° C, and City B was −1° C.
City A was 8° C, and City B was −3° C.
City A was 5° C, and City B was −5° C.
City A = x
City B = y
1st equation: 4x-8 =3y
2nd equation: x-2y = -3 , rewrite as x = 2y-3
replace x in eq. 1 with equation 2
4(2y-3) -8 =3y
8y-12-8=3y
8y-20 = 3y
-20 = -5y
y = -20/-5 = 4
x = 2y-3 = 2(4)-3 = 5
City A was 5° C, and City B was 4° C.

The formula to convert Celsius to Fahrenheit is f= 9/5c+32. Convert 45degreesF to Celsius. Round to the nearest degree.
Answer:
45 degrees Fahrenheit = 7.3 Celsius
Step-by-step explanation:
The formula to convert Celsius to Fahrenheit is given by :
[tex]F=\dfrac{9}{5}C+32[/tex]
In this case, it is required to convert degree Fahrenheit to Celsius. It can be simply done by putting the value of F = 45 degrees Fahrenheit to Celsius. So,
[tex]C=\dfrac{(F-32)5}{9}[/tex]
[tex]C=\dfrac{(45-32)5}{9}[/tex]
C = 7.222
or
T = 7.3 Celsius
So, 45 degrees Fahrenheit is equal to 7.3 Celsius. Hence, this is the required solution.
Vivian is going to do some yard work, but she needs to leave her house at 1:00 to go to a football game. She is going to mow the lawn for 1 hour and 10 minutes, trim some bushes for 30 minutes, and put down some mulch for 35 minutes. She will also need 20 minutes to shower and get dressed. What time should she start the work so she will be ready at 1:00?
Answer:
Vivian should start working by 10.25 am.
Step-by-step explanation:
Time taken to mow the lawn = 1 hour and 10 minutes
Time to trim bushes = 30 minutes
Time for putting down mulch = 35 minutes
Time to get dressed = 20 minutes.
Total time = 1 hour + (10+30+35+20) minutes
= 1 hour + 95 minutes
= 1 hour + (60+35) minutes
= 1 hour + 1 hour + 35 minutes
= 2 hours 35 minutes.
This means Vivian should start working 2 hours 35 minutes before 1:00 pm.
So, it becomes ; 10:25 am.

A one compartment vertical file is to be constructed by bending the long side of an 8 in 8 in. by 10 10 in. sheet of plastic along two lines to form a U shape. How tall should the file be to maximize the volume that it can hold?
In order to maximize the volume of the file, it should be 2 inches high. This is calculated using the optimization principle in calculus applied to the volume formula of a rectangular prism.
Explanation:This problem involves optimizing the volume of a vertically filed object, which is a common theme in calculus. The file is being formed from a rectangular sheet of plastic that is 8 inches by 10 inches by bending it to form a U-shape.
The volume of a rectangular prism (which is what the file will essentially be) is given by the formula length x width x height. In this case, the length will always be 10 inches because it's the undisturbed dimension. The 8-inch side will be divided into a height part and a width part once we bend it into a U shape. Since we don't know a priori what the height is yet, let's call it x. This means the width will then be 8 - 2x (since we lose x from each side to form the height).
Our volume function V becomes: V(x) = length x width x height = 10(8-2x)x. To maximize this volume, you want to take the derivative V'(x), set it to 0 and then solve for x. Taking the derivative will give you V'(x) = 10(8-4x), and setting it to 0 and solving gives you x = 2 inches. So, the file should be 2 inches high to maximize the volume it can hold.

If triangle ABC is congruent to triangle XYZ, then which of the following is congruent to ∠A?
∠C
∠X
∠Y
∠Z
Answer: ∠X
Step-by-step explanation:
If ΔABC is congruent to ΔXYZ then their corresponding parts must be congruent by CPCTC.
To find the corresponding angle to ∠A, just check the position of A in the name of ΔABC,
A is the first letter in the name of ΔABC, thus the angle corresponding to ∠A is ∠X.
CPCTC (congruent parts of corresponding angles are congruent) tells that if two triangles are congruent then the corresponding angles and sides are congruent .Determine the function which corresponds to the given graph. a natural logarithmic function crossing the y axis at zero and going through the point 2,1.
The asymptote is x = -1.
Answer:
The function for the given description is y = ln (x + 1) - 0.098 .
Step-by-step explanation:
As you can see in the problem the asymptote is x = -1. This means that the function is not defined for x= -1 and as you know, natural logarithm is not defined for zero. So, it implies that when x tends to -1 the function tends to infinite. So it must be a number adding to x that makes -1 + b = 0 ⇒ b= 1.
Then, you have y = ln (x + 1). If you check, when you replace the point given in the problem (2,1), you find that y = ln (2 + 1) ⇒ y = ln(3) ⇒ y = 1.098, so you can introduce a correction factor ⇒ y = ln (x + 1) - 0.098.
Summarizing, the function decribed before can be y = ln (x + 1) - 0.098.
Suppose rebecca needs a dog sitter so that she can travel to her sister's wedding. rebecca values dog sitting for the weekend at $200. susan is willing to dog sit for rebecca so long as she receives at least $175. rebecca and susan agree on a price of $185. suppose the government imposes a tax of $30 on dog sitting. the tax has made rebecca and susan worse off by a total of
Final answer:
With the imposition of a $30 tax on dog sitting, Rebecca and Susan would both be worse off by the combined surplus of $25 they initially had without the tax, as the tax exceeds the surplus and disrupts the transaction.
Explanation:
The question involves the impact of a tax on a market transaction between Rebecca and Susan, who had initially agreed upon a price for dog sitting. Initially, without the tax, the surplus for Rebecca would be the difference between what she values the service at ($200) and the agreed price ($185), which is $15. For Susan, the surplus is the difference between the agreed price ($185) and her minimum acceptable price ($175), which is $10. This results in a combined surplus of $25. When a $30 tax is imposed, it is likely that they will share the burden of the tax, but without specifics on how the tax is divided, we will consider it fully affects either party. If the full tax falls on Susan, she would receive $155 ($185 - $30), which is less than her minimum price of $175; thus, she would no longer agree to dog sit. If Rebecca bears the entire tax, she would effectively be paying $215 ($185 + $30), which is more than her valuation of $200, and she would not agree to the transaction. Regardless, the transaction would not occur due to the tax, making both parties worse off by the surplus they would have gained, which is the combined $25.
In a flock of black and white sheep, 2 out of 5 sheep are white. If there are 8 more black sheep than white sheep, how many sheep are in the flock?
To find the total number of sheep in the flock where 2 out of 5 are white and there are 8 more black than white sheep, we set up a ratio and solve for the number of white sheep (W), which is 16. We then determine the number of black sheep (B) to be 24, leading to a total of 40 sheep.
Explanation:The subject of the question is mathematics, and it appears to be at the middle school level. The task involves determining the total number of sheep given that 2 out of 5 are white and there are 8 more black sheep than white. Let's define the variables: W for white sheep and B for black sheep. From the statement, we have the ratios W/B = 2/3 because for every 2 white sheep, there are 3 black sheep which are proportionally 5 sheep in total (2+3=5), and we have the relationship B = W + 8 because there are 8 more black than white sheep. Using these equations, we can solve for W and B.
From the ratio W/B = 2/3, we can express B as B = 3/2 * W.Replace B in the second equation with 3/2 * W:Therefore, the total number of sheep in the flock is 40.

The easton west high school marching band has 52 members and the weston HIgh school marching band has 65 members.They are going to march in a parade. How can they be arranged so that each row has the same number of players? the players in each school have to separate.
A)Rows of 4
B)Rows of 13
C)Rows of 5
D )Rows of 8
Need help ASAP
Answer: Option 'B' is correct.
Step-by-step explanation:
Since we have given that
Number of members in the easton west high school marching = 52
Number of members in the weston high school marching = 65
We need to find the number of rows so that each row has the same number of players.
For this we will do L.C.M. of 52 and 65.
So, L.C.M. of 52 and 65 = 13
Hence, there are 13 rows in all.
Therefore, Option 'B' is correct.
