Answer:
a. 18 units, 18 units, 13 units
Step-by-step explanation:
P = 49 means the sum of side lengths is 49. Only answer choice A has numbers that sum to 49.
___
As here, you often do not need to work a multiple-choice problem. You only need to check to see which answers make sense.
__
If you want to actually compute the side lengths, you know the two sides with a hash mark are the same length, so the perimeter is ...
P = 49 = (2n+2) + (2n+2) + (2n-3) = 6n +1
48 = 6n . . . . . subtract 1
8 = n . . . . . . . divide by 6
Then ...
2n +2 = 2·8 +2 = 18 . . . . . . . matches only the first answer choice.
Find the value of a in the equation 5/a+3 = 3/a-2
Answer:
D 9 1/2
Step-by-step explanation:
5/(a+3) = 3/(a-2)
We can use cross products to solve
5 * (a-2) = 3 * (a+3)
Distribute
5a - 10 = 3a +9
Subtract 3a from each side
5a -3a -10 = 3a -3a +9
2a -10 =9
Add 10 to each side
2a -10+10 = 9+10
2a = 19
Divide each side by 2
2a/2 = 19/2
a = 19/2
a = 9 1/2

Answer:
32°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the trig function relating angles to the opposite and adjacent sides of the triangle is ...
Tan = Opposite/Adjacent
The side opposite the angle x is shown as having measure 5; the side adjacent has measure 8. Putting all this in the above equation gives ...
tan(x) = 5/8
To find the angle from the value of the tangent, you use the inverse of the tangent function. The name of that is the arctangent function. It is often written as tan⁻¹(x) and often accessible on your calculator using a "second function" key. Some calculators, like the one shown in the attachment, recognize the arctan function name.
x = arctan(5/8) ≈ 32°
The value of x rounded to the nearest whole degree is 32°.
A car manufacturer is reducing the number of incidents with the transmission by issuing a voluntary recall. During week 2 of the recall, the manufacturer fixed 192 cars. In week 4, the manufacturer fixed 184 cars. Assume that the reduction in the number of cars each week is linear. Write an equation in function form to show the number of cars seen each week at the mechanic.
A.) f(x) = 4x + 200
B.) f(x) = 2x + 192
C.) f(x) = −4x + 200
D.) f(x) = −2x + 192
Answer:
C.) f(x) = −4x + 200
Step-by-step explanation:
Since the number is decreasing, you know the slope will be negative, eliminating the first two choices. The equation in the last choice does not match the given data, so it can be eliminated.
In other words, the easiest way to solve this problem is to check the answers against the given data.
_____
If you want to write the equation from scratch, you need to find the slope. That is ...
(change in number of cars)/(change in weeks) = (184 -192)/(4 -2) = -8/2 = -4
This matches only one answer, but you can go on to finish the equation by starting with point-slope form:
y -192 = -4(x -2)
y = -4x +8 +192 . . . . add 192, eliminate parentheses
y = -4x + 200 . . . . matches choice C.)

in circle P, what is the measure of ADB?
Answer:
arc ADB = 270°
Step-by-step explanation:
Arc ADB is the remainder of the circle after subtracting 90° arc AB. Its measure is ...
ADB = 360° -90° = 270°
Write the slope intercept equation for line AB.
Answer:
A( 3, 2)
B( 1, 2)
y=kx+b
3k+b=2
k+b=2
3k-k+b-b=0
2k=0
k=0
b=2
The equation is y=2
Answer: B is correct, y=2
Step-by-step explanation:
The formula for a line is y=mx+b, m is slope, and b is the y-intercept.
The line AB is completely flat, which means the slope is 0, so it won't show up in the equation. So right now we know the equation will be y=b. Now, we mist find b, the y-intercept. The line AB is crossing the y-axis at 2, meaning that's your y-intercept/b! The equation is y=2
Multiple-choice questions have a special grading rule determined by your instructor. Assume that your instructor has decided to grade these questions in the following way: If you submit an incorrect answer to a multiple-choice question with n options, you will lose 1/(n−1) of the credit for that question. Just like the similar multiple-choice penalty on most standardized tests, this rule is necessary to prevent random guessing.If a multiple-choice question has five answer choices and you submit one wrong answer before getting the question correct, how much credit will you lose for that part of the question?
Answer:
1/4 of the credit
Step-by-step explanation:
The problem statement tells you n=5. Putting that into the expression for lost credit, you get ...
1/(5-1) = 1/4
of the credit is lost for a question with 1 wrong answer.
You will lose 1/4 of the credit.
Answer:
The credit will you lose for the part of question is 1/4 or 25%.
Step-by-step explanation:
Consider the provided information.
It is given that, if you submit an incorrect answer to a multiple-choice question with n options, you will lose 1/(n−1) of the credit for that question.
Suppose the given multiple choice question has 5 answer. So for one wrong answer the loss will be:
Substitute the value of n=5 in above formula.
[tex]\frac{1}{n-1} \\\frac{1}{5-1} \\\frac{1}{4}=0.25[/tex]
That means you will lose 1/4 or 0.25credit.
Now convert it into %.
[tex]\frac{1}{4}\times 100=25\%[/tex]
Hence, the credit will you lose for the part of question is 1/4 or 25%.
A scientist wants to research the potential spread of germs by contact. She knows that the number of possible handshakes within a group of n people is given by the equation Nequalsone half left parenthesis n squared minus n right parenthesis . Everyone at a party shook hands. There were 171 handshakes in all. How many people attended the? party?
Answer:
19
Step-by-step explanation:
Here we have to find out number of people attended the party. we are given with the number of the handshakes in the party .
We are going to use the following formula to determine the number of guests
Nos. of handshakes
[tex]H=\frac{1}{2}(n^2-n)[/tex]
Here we have H = 171
Hence our equation becomes
[tex]171=\frac{1}{2}(n^2-n)[/tex]
now we solve it by splitting the middle term method
[tex]171=\frac{1}{2}(n^2-n)\\2*171 =n^2-n\\n^2-n=342\\n^2-n-342=0\\[/tex]
Now we have to find the factors of 342 whose difference to 1. The factors are 19 and 18 in this case. hence we slit our middle term like this
[tex]n^2-n-342=0\\n^2-19n+18n-342=0\\n(n-19)+18(n-19)=0\\(n-19)(n+18)=0\\[/tex]
Hence
either
(x+18)=0 or (x-19) =0 Thus
x=-18 which is not possible as no of people can not be less than 0
x=19 which will our answer

Answer:
x = 4 or x = 1
Step-by-step explanation:
Solving absolute value equations can be a bit tricky. Absolute values are actually distance measurements. A very simple example is I x - 3 I = 2 says that "x is 2 units away from 3 on a number line". 2 units from 3 going to the right is 5, 2 units from 3 going to the left is 1. So in other words, absolute value equations will have 2 answers, in this case 2 units to the right (+2) and 2 units to the left (-2). That means that x - 3 = 2 OR x - 3 = -2. Let's start to solve this one:
5I 2x - 5 I - 3 = 12
Start by adding 3 to both sides:
5I2x-5I = 15
Now divide both sides by 5:
I2x-5I = 3
We will set the left side equal to both +3 and -3 to get our 2 solutions:
2x - 5 = 3 and 2x - 5 = -3
Solving the first one for x:
2x = 8 and x = 4
Solving the second one:
2x = 2 and x = 1.
Fit these into the original absoute value statement and see if they are both true:
5I2(4)-5I-3=12 --> 5I3I - 3 = 12 and 15 - 3 = 12
5I2(1)-5I-3 = 12 --> 5I-3I - 3 = 12. The absolute value of -3 is 3, so 15 - 3 = 12. They both check out@

What is an equation of the line that is parallel to y=5−3x and passes through (0, 2) ?
Enter your equation in the box.
Remember that the slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
so...
y = -3x + 5
If lines are parallel then they have the same slope (m)
This means that the slope of the line will be -3
y = -3x + b
Now we must find b
To do that you must plug in the point the line goes through in the x and y of the equation.
(0, 2)
2 = -3(0) + b
2 = 0 + b
2 = b
y = -3x + 2
Hope this helped!
~Just a girl in love with Shawn Mendes
In the equation y = mx + b, where m represents the slope and b represents the y-intercept, we can determine the slope of the line to be -3. When two lines are parallel, they have the same slope (m).
To find the value of b, we need to substitute the coordinates of a point the line passes through into the equation. In this case, the point is (0, 2).
By plugging in the values, we get:
2 = -3(0) + b
2 = 0 + b
2 = b

The price of gasoline increased 25% from July to August. If c = cost of gasoline in July, write two expressions that represent the price of gas in August.
If you know the cost of gas in July, which expression do you think would be easier to use to calculate the cost of gas in August and why?
Answer:
1. august price = c + 0.25c
2. august price = 1.25c
Step-by-step explanation:
The problem statement tells us that the price of gas in August is 25% more than in July. Thus, 25% of the July price (0.25c) is added to the July price (c) to get the August price.
c + 0.25c
The sum in the first part can be simplified by combining the coefficients of c.

d) The yellow rectangle was translated right 5 units and up 3 units.
Step-by-step explanation:
Translation in geometry describes a function that moves an object a certain distance without altering it. The object is not rotated, reflected or re-sized after translation. Every point of the object is moved in the same direction through the same distance.
Reflection is a rigid transformation in which the given object is flipped across a line to create its image. Each point of the image maintains their distance from the line as in the object. In reflection, every point of the object changes initial location.
The options that describe the transformation are: The yellow rectangle was translated right 5 units and reflected over the x-axis, and the yellow rectangle was translated right 5 units and up 3 units.

Take b/2 and use it in the the (x+b/2)^2
(x+4)^2 = 54
Take the square root of each side
sqrt((x+4)^2) = ± sqrt(54)
x+4 = ± sqrt(54)
Subtract 4 from each side

Answer:
x = 39/74 - sqrt(1817)/74 or x = 39/74 + sqrt(1817)/74
Step-by-step explanation:
Solve for x:
(x - 4) (3 x - 2) - ((6 - 5 x) (x - 4) (8 x - 1))/(4 - x) = 0
Simplify and substitute y = 4 - x.
(x - 4) (3 x - 2) - ((6 - 5 x) (x - 4) (8 x - 1))/(4 - x) = -434 + 257 (4 - x) - 37 (4 - x)^2
= -37 y^2 + 257 y - 434:
-37 y^2 + 257 y - 434 = 0
Divide both sides by -37:
y^2 - (257 y)/37 + 434/37 = 0
Subtract 434/37 from both sides:
y^2 - (257 y)/37 = -434/37
Add 66049/5476 to both sides:
y^2 - (257 y)/37 + 66049/5476 = 1817/5476
Write the left hand side as a square:
(y - 257/74)^2 = 1817/5476
Take the square root of both sides:
y - 257/74 = sqrt(1817)/74 or y - 257/74 = -sqrt(1817)/74
Add 257/74 to both sides:
y = 257/74 + sqrt(1817)/74 or y - 257/74 = -sqrt(1817)/74
Substitute back for y = 4 - x:
4 - x = 257/74 + sqrt(1817)/74 or y - 257/74 = -sqrt(1817)/74
Subtract 4 from both sides:
-x = sqrt(1817)/74 - 39/74 or y - 257/74 = -sqrt(1817)/74
Multiply both sides by -1:
x = 39/74 - sqrt(1817)/74 or y - 257/74 = -sqrt(1817)/74
Add 257/74 to both sides:
x = 39/74 - sqrt(1817)/74 or y = 257/74 - sqrt(1817)/74
Substitute back for y = 4 - x:
x = 39/74 - sqrt(1817)/74 or 4 - x = 257/74 - sqrt(1817)/74
Subtract 4 from both sides:
x = 39/74 - sqrt(1817)/74 or -x = -39/74 - sqrt(1817)/74
Multiply both sides by -1:
Answer: x = 39/74 - sqrt(1817)/74 or x = 39/74 + sqrt(1817)/74
Need help with this counterclockwise rotation
Answer: [tex](-2,1)[/tex]
Step-by-step explanation:
It is important to remember that a rotation is a transformation in which the shapes and sizes do not change, but the object can be turned in different directions.
By definition, the rule for 180° counterclockwise rotation is this:
[tex](x,y)[/tex]→ [tex](-x,-y)[/tex]
Therefore, we know that the image of the point [tex]P=(2,-1)[/tex] under a 180° counterclockwise rotation is:
[tex](2,-1)[/tex]→ [tex](-2,1)[/tex]
At all trials and hearings, a court reported types every word spoken during the proceedings so that there is a written record of what transpired. Because they must type every word, the average court reporter must be able to type a minimum rate of 3.75 words per second in order to be certified. Suppose a trial transcript contains 25 pages with an average of 675 words per page. Assuming the court reporter typed the transcript at the minimum rate, how long was she actively typing?
A) 1 hour, 15 minutes
B) 1 hour, 45 minutes
C) 2 hours, 30 minutes
D) 3 hours
Answer:
A
Step-by-step explanation:
She can type 3.75 words per second.
There are 60 seconds in a minute
Therefore she can type 3.75 * 60 = 225 words per minute.
If 1 page contains 675 words, it will take 675 // 225 words /min = 3 minutes
Therefore 25 pages will take 75 minutes (3 * 25 = 75)
75 minutes = 1 hour with 15 minutes left over.
Final answer:
The court reporter, typing at a minimum rate of 3.75 words per second, would have spent 1 hour and 15 minutes actively typing a 25-page trial transcript with an average of 675 words per page.
Explanation:
The question asks us to calculate the time a court reporter would have spent actively typing a transcript. To find this duration, we first determine the total number of words the trial transcript contains by multiplying the number of pages by the average number of words per page. Then, we divide the total number of words by the court reporter's typing speed in words per second to find the total time in seconds. Finally, we convert the total time from seconds into minutes and hours to get the answer in a more understandable format.
First, calculate the total number of words:
25 pages × 675 words per page = 16,875 words
Next, convert the court reporter's minimum typing speed into words per second:
3.75 words per second
Now, calculate the time spent typing:
Total time (in seconds) = Total number of words ÷ Words per second
Total time (in seconds) = 16,875 words ÷ 3.75 words/second = 4,500 seconds
Convert seconds to minutes: 4,500 seconds ÷ 60 = 75 minutes
Convert minutes to hours: 75 minutes ÷ 60 = 1.25 hours
Therefore, the court reporter was actively typing for 1 hour, 15 minutes, which corresponds to option A.
Jill wants to save to buy a car. She decides to open a banking account that is offering a simple interest rate of 4.5% annually. How much will Jill have in her account after 5 years if she deposits $7,000 today?
Answer:
The interest is: $1575
The total is: $8575
Step-by-step explanation:
7000*5*0.045 gets you the interest
Then you add the original amount, 7000, to the total
1575+7000=$8575
By using the Simple Interest formula (Principal * Rate * Time), we find that Jill will earn $1575 in interest over 5 years. Therefore, she will have $8575 in her account after 5 years.
Explanation:To calculate how much Jill will have in her account after 5 years, we can use the simple interest formula, which is Principal * Rate * Time.
In Jill's case, the principal is the amount she initially deposited which is $7000. The rate is the simple interest rate offered by the bank annually, expressed as a decimal, so 4.5% becomes 0.045. The time is the number of years that the money remains in the account, which is 5 years.
By substituting these values into the formula, we have: $7000 * 0.045 * 5 = $1575.
This means the total interest Jill would earn over 5 years is $1575. The total amount in the account after 5 years would be the initial amount plus the interest, so $7000 + $1575 = $8575.

Expected value- Any discrete variable's expected value is probability-weighted average of all of its possible values.
In simple words, any possible value that can be inferred by the any given variable is compounded by its probability of occurrence and the resulting products are added up to deliver the expected value.
Need help with math question
Answer:
80%
Step-by-step explanation:
We are given the results of survey of one thousand families to determine the distribution of families by their size.
We are to find the probability (to the near percent) that a given family has more than 6 people.
Frequency of people with less than 5 people = 350 + 200 + 245 = 795
Total frequency = 1000
P (families with fewer than 5 people) = (795 / 1000) × 100 = 79.5% ≈ 80%
PLEASE HELP ASAP I WILL MARK BRAINLIEST!! ABCD is rotated counterclockwise about the origin. By how many degrees was ABCD rotated?
Answer:
270 degrees
Step-by-step explanation:
180 would be diagonal from original, 360 would be where the original is and 90 would be in the second quadrant so therefore its 270

Answer:
-3, 1, 4 are the x-intercepts
Step-by-step explanation:
The remainder theorem tells you that dividing a polynomial f(x) by (x-a) will result in a remainder that is the value of f(a). That remainder will be zero when (x-a) is a factor of f(x).
In terms of finding x-intercepts, this means we can reduce the degree of the polynomial by factoring out the factor (x-a) we found when we find a value of "a" that makes f(a) = 0.

For the given polynomial, we notice that the sum of the coefficients is zero:
1 -2 -11 +12 = 0
This means that x=1 is a zero of the polynomial, and we have found the first x-intercept point we can plot on the given number line.
Using synthetic division to find the quotient (and remainder) from division by (x-1), we see that ...
f(x) = (x -1)(x² -x -12)
We know a couple of factors of 12 that differ by 1 are 3 and 4, so we suspect the quadratic factor above can be factored to give ...
f(x) = (x -1)(x -4)(x +3)
Synthetic division confirms that the remainder from division by (x -4) is zero, so x=4 is another x-intercept. The result of the synthetic division confirms that x=-3 is the remaining x-intercept.
The x-intercepts of f(x) are -3, 1, 4. These are the points you want to plot on your number line.
