A triangle has a perimeter of 48 feet. If the three sides of the triangle are n, 4n−2, and 4n−4, what is the length of each side?

Answers

Answer:

6; 22; 20 (ft.)

Step-by-step explanation:

1) if the length of the each side are: n; 4n-2 and 4n-4, then the expression of the perimeter can be written: P=n+4n-2+4n-4 or P=9n-6.

2) if according to the condition perimeter is 48 (ft.), then

9n-6=P; ⇔ 9n-6=48; n=6.

3) if n=6, then the required lengths of the sides are:

n=6 (ft.);

4n-2=22 (ft.);

4n-4=20 (ft.)

Todd and Garrett began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Todd took a test in Math and earned a 74.6, and Garrett took a test in English and earned a 68.8. Use the fact that all the students' test grades in the Math class had a mean of 70.6 and a standard deviation of 11.9, and all the students' test grades in English had a mean of 63.7 and a standard deviation of 8.6 to answer the following questions.

Required:
a. Calculate the z-score for Todd's test grade.
b. Calculate the z-score for lan's test grade.
c. Which person did relatively better?

Answers

Part A

For Todd's class, we have this given info:

mu = 70.6 = population mean of math scoressigma = 11.9 = population standard deviation of math scores

Compute the z score for x = 74.6

z = (x-mu)/sigma

z = (74.6 - 70.6)/(11.9)

z = 0.34 approximately

Side note: Convention usually has z scores rounded to two decimal places. If your teacher instructs otherwise, then go with those instructions of course.

Answer:  0.34

======================================================

Part B

For Garret's English class, we have:

mu = 63.7sigma = 8.6

Compute the z score for x = 68.8

z = (x-mu)/sigma

z = (68.8 - 63.7)/(8.6)

z = 0.59 approximately

Answer:  0.59

======================================================

Part C

Garret has the higher z score, which means that Garret did relatively better to his classmates compared to Todd's performance (in relation to his classmates). The z score is the distance, in units of standard deviation, the score is from the mean. Positive z values are above the mean, while negative z values are below the mean.

Answer: Garret did relatively better

Find the exact circumference of the circle. please help?

Answers

Answer:

3rd option

Step-by-step explanation:

We first need to find the diameter of the circle.

We know this is a square because all sides are marked by a line so this means they are equal. Let find the diagonal of the square to find all parts of the square.

The diagonal of a square is

[tex]a \sqrt{2} [/tex]

where a is the side lengths of the square.

So this means the diagonal of the square is

[tex]18 \sqrt{2} [/tex]

The diagonal is also the diameter of the main circle. The formula for circumference is

[tex]d\pi[/tex]

where d is the diameter.

So the diameter is

[tex](18 \sqrt{2} )\pi[/tex]

or

[tex]18\pi \sqrt{2} [/tex]

The third option is correct

Question
Find the equation of the line with slope m
=
2 that contains the point (8,19).

Answers

Answer: y= 2x + 3

Step-by-step explanation:

Point slope formula: y = mx + b

Since the given point is (8,19), 19 is our y, and 8 is our x. Since the slope is 2, our m is 2.

Sub in values.

y = mx + b

19 = 2(8) +b

19 = 16 + b

b = 19-16

b = 3

Now that we have m and b, we can make the equation.

y = mx + b, sub in 2 for m and 2 for b

y = 2x + 3

19 = 2(8) + 3

19 = 16 + 3

19 = 19

So the answer is y = 2x+3

Evaluate 6 to the power of negative 2

A. -1/36
B. -12
C. -36
D. 1/36

Answers

Answer:

Positive 1 over 6 raised to the 2nd power 1/62 or 1 over 36 which is 1/36. To find -6-2, take the inverse of -62.

(first find -62) -62 = -6 * -6 = 36

(then take the inverse of 36, which is 1 over 36) = 1 / 36 = 0.0277

What is the value of this expression?

​ 1.5(−2.4+(−5.3))

Answers

Answer:

-11.55

Step-by-step explanation:

(to get the numbers out of the brackets you have to multiply all the numbers in the brackets to the number that is there, and in this case its 1.5)

1.5x(-2.4)= -3.6

1.5×(-5.3)= -7.95

after that, you add them (because there is a plus sign, not a minus, multiplication sign or a division sign.)

-7.95+ -3.6= -11.55

answer= -11.55

Points A, B, and C are collinear. Point B is between A and C. Find the length indicated. AB= 5x-15, BC=3x-5, and AC=28. Find AB

Answers

Answer: AB is 15

Step-by-step explanation: First, you need to draw a picture and label the parts of the line: AB=5x-15; BC= 3x-5; AC =28. Because of the segment addition postulate, you set the equation to be 5x-15+3x-5=28. Then you solve:

5x-15+3x-5=28

Add like terms:

8x-20=28

Add 20 to both sides

8x=48

Divide by 8

x=6

Now, you need to find the measure of AB, so you plug the 6 into the x variable for 5x-15

5(6)-15

30-15

AB=15

find the equation of the line that is perpendicular to y=1/2x -4 and contains the point (4, 5)

Answers

Answer:

the equaion of the new line is y = -2x + 13

Step-by-step explanation:

The slope of this line is 1/2.  Recall that if we are given such a slope and want the slope of a line perpendicular to the given line, we find the negative reciprocal of the slope of the given line.  Here, given m = 1/2, the slope of any line perpendicular to the given line is m = -2.

Now insert this info into the standard slope-intercept equation of a line:

y = mx + b becomes 5 = (-2)(4) + b.  Solve this for b:

5 + 8 = b = 13.

Thus, the equaion of the new line is y = -2x + 13.


Using the method of completing the square, rewrite x² – 14x in the form (x + b)2 +c.

so that

[tex]\begin{cases}2b=-14 \\ b^2+c=0\end{cases}[/tex]

Find the sides of a rectangle whose area is given as x2 +15x +56.

Answers

(x+7) (x+8) so the sides of the rectangle is 7 and 8

x^2 + 15x + 56

Good way to factor quadratic functions:

In a function x^2 +bx + c

Find two number that when multiplied together will form c (in our case 56) and that when added together form b (in our case 15)

Number 1 x Number 2 = 56

Number 1 + Number 2 = 15

Number 1 = 8

Number 2 = 7

(It'll be easier to find these numbers with practice)

Now in the function instead of bx, split it and use (number 1)x + (number 2)x

It's allowed because it's the same value since N1 + N2 = bx already

x^2 + 15x + 56

Now is:

x^2 + 8x + 7x + 56

Now you can factor this function much easily because it can transformed into:

(x + 8)(x) + (x + 8)(7)

x + 8 is the common factor

it can become:

(x + 8) (x + 7)

The sides of the rectangle are 8 and 7

Hope this helps you with factoring :)

There are 500 seats on a plane flying to San Francisco. 20% of the seats are next to a window. How many of the seats are next to a window?

Answers

Answer:

There are 100 seats that are next to a window.

Step-by-step explanation:

You have to calculate 20% of the total number of seats.

20% can also be written as 20/100

so 20/100 x 500. If you solve this then you will get 100. Therefore, 100 seats are next to a window.

Answer: 100 seats are next to a window.

Step-by-step explanation: 1. We assume, that the number 500 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 500 is 100%, so we can write it down as 500=100%.

4. We know, that x is 20% of the output value, so we can write it down as x=20%.

5. Now we have two simple equations:

1) 500=100%

2) x=20%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

500/x=100%/20%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 20% of 500

500/x=100/20

(500/x)*x=(100/20)*x       - we multiply both sides of the equation by x

500=5*x       - we divide both sides of the equation by (5) to get x

500/5=x

100=x

x=100

now we have:

20% of 500=100
