Step-by-step explanation:
(A) Find the midpoint of the segment
(B) Find the length of the segment
Answer:
The midpoint is (1, 3) and the length of the segment (let's call it AB) is 6.32
Step-by-step explanation:
Answer:
A) (1, 3)
B) [tex]2\sqrt{10}\\[/tex]
Step-by-step explanation:
A) We are finding the averages of the x and y values. The midpoint formula is as so:
(x1 + x2/2, y1 + y2/2)
(-2+4/2 , 4+2/2)
(2/2 , 6/2)
(1.3)
With distance, the formula is[tex]\sqrt{(x_{1} -x_{2})^{2} + (y_{1} -y_{2})^{2}[/tex]
[tex]\sqrt{(4-(-2))^{2} + (2-4)^{2}[/tex]
[tex]\sqrt{(6)^{2} + (-2)^{2}[/tex]
[tex]\sqrt{36 + 4}[/tex]
[tex]\sqrt{40}[/tex]
[tex]2\sqrt{10}[/tex]

Top surface of an umbrella look like regular octagon as shown in the figure below find the area
Answer:
Area of figure = 5,095 cm²
Step-by-step explanation:
Given:
Two trapezium
One rectangle
Find:
Area of figure
Computation:
Area of figure = Area of rectangle + Area of 2 trapezium
Area of figure = [L x B] + 2[(1/2)(Sum of parallel side)(Height)]
Area of figure = [118 x 15] + 2[(1/2)(118+15)(25)]
Area of figure = 1,770 + 3,325
Area of figure = 5,095 cm²

What’s the solution for y=2x+7 y=3x-1
Answer:
x=8 and y=23
Step-by-step explanation:
Rewrite equations:
y=2x+7;y=3x−1
Step: Solve y=2x+7 for y:
y=2x+7
Step: Substitute 2x+7 for y in y=3x−1:
y=3x−1
2x+7=3x−1
2x+7+−3x=3x−1+−3x(Add -3x to both sides)
−x+7=−1
−x+7+−7=−1+−7(Add -7 to both sides)
−x=−8−x−1=−8−1
(Divide both sides by -1)
x=8
Step: Substitute 8 for x in y=2x+7:
y=2x+7
y=(2)(8)+7
y=23(Simplify both sides of the equation)

Dayami works at Future Shop and earns $10.50/h plus 6% commission on sales. Last
week Dayami worked 40 hours. What was Dayami’s weekly gross salary if her total sales
were $2050?Dayami works at Future Shop and earns $10.50/h plus 6% commission on sales. Last
[tex]= \tt\$570[/tex]
Answer with steps :Money Dayami earns for an hour's work = $10.50
Number of hours Dayami worked last week = 40
Money Dayami would have gotten for her work :
[tex] =\tt 10.50 \times 40[/tex]
[tex] =\tt \$ \: 420[/tex]
Thus, money earned by Dayami for her work = $420
Total sales Dayami made last week = $2050
Money Dayami must have earned as commission :
= 6% of total sales
[tex] = \tt6 \% \: of \: 2500[/tex]
[tex] = \tt\frac{6}{100} \times 2500[/tex]
[tex] =\tt \frac{15000}{100} [/tex]
[tex] =\tt \$150[/tex]
Thus, money Dayami earned as a commission = $150
Dayami's weekly gross salary last week :
[tex] = \tt420 + 150[/tex]
[tex] =\color{plum} \tt \: \$570[/tex]
Thus, total salary = $570
Therefore, Dayami's gross salary last week = $570

The teachers had to transport 165 students by bus on a field trip. Each bus holds 64 students. How many buses do they need to order?
Answer:
3 buses
Step-by-step explanation:
Divide 165 by 64 ≈ 2.6 which you would round up to 3
64 • 3 = 192 students so there is room left over

A piece of paper is to display 150, space square inches of text. If there are to be one-inch margins on the sides and the top and a two-inch margin at the bottom, what are the dimensions of the smallest piece of paper that can be used? Choose 1 answer:
Answer:
[tex]Height = 8.660\ in[/tex]
[tex]Width = 17.321\ in[/tex]
Step-by-step explanation:
Given
[tex]Area= 150in^2[/tex]
[tex]Side\ Margin = 1\ in[/tex]
[tex]Top\ \&\ Bottom\ Margins = 2\ in[/tex]
Required
Determine the smallest dimension to use
To answer this question, I'll make use of the attached figure as a point of reference.
The area of the printed matter is:
[tex]Area = Length * Width[/tex]
[tex]A_1 = H * W[/tex]
Substitute 150 for A1
[tex]150 = H * W[/tex]
Make H the subject
[tex]H = \frac{150}{W}[/tex]
The area of the full paper is:
[tex]Area = Length * Width[/tex]
[tex]A_2 = (W + 2+2) * (H + 1 + 1)[/tex]
[tex]A_2 = (W + 4) * (H + 2)[/tex]
Substitute 150/W for H
[tex]A_2 = (W + 4) * (\frac{150}{W} + 2)[/tex]
Open brackets
[tex]A_2 = W(\frac{150}{W} + 2) + 4(\frac{150}{W} + 2)[/tex]
[tex]A_2 = 150 + 2W + \frac{600}{W} + 8[/tex]
Collect Like Terms
[tex]A_2 =2W + \frac{600}{W} + 8+150[/tex]
[tex]A_2 =2W + \frac{600}{W} + 158[/tex]
Differentiate with respect to w and set the result to 0
[tex]A_2' = 2 - \frac{600}{W^2} + 0[/tex]
[tex]A_2' = 2 - \frac{600}{W^2}[/tex]
Set to 0
[tex]0 = 2 - \frac{600}{W^2}[/tex]
Collect Like Terms
[tex]2 = \frac{600}{W^2}[/tex]
Cross Multiply
[tex]2 * W^2 = 600[/tex]
Make [tex]W^2[/tex] the subject
[tex]W^2 = \frac{600}{2}[/tex]
[tex]W^2 = 300[/tex]
Take positive square root of both sides
[tex]W = 17.321[/tex]
Recall that:
[tex]H = \frac{150}{W}[/tex]
[tex]H = \frac{150}{17.321}[/tex]
[tex]H = 8.660[/tex]
Hence, the smallest dimension of the paper is:
[tex]Height = 8.660\ in[/tex]
[tex]Width = 17.321\ in[/tex]
Answer:
H=18
W=12
Step-by-step explanation:
The question says 1 inch margins on the sides AND the top. And THEN a 2 inch margin ONLY on the bottom.
First, solve for y,
A = xy
150 = xy
150/x = y
If the center dimensions is A and its it equals x*y, then plus the margins, the outer dimensions would just be x+(size of margins) for width and y+(size of margins) for height.
This gives us
Width: x + 2
Height: y + 3
Putting height into terms of x: (Substitute y) = 3 + 150/x
Now, since the area of a rectangle is b*h, the equation is:
(x + 2)(3 + 150/x)
Simplify:
3x + 150 + 6 + 300/x
= 3x + 156 + 300/x
Next, we find the derivative of this and then solve for x.
= 3 - 300/x^2
Solving for x:
0 = 3 - 300/x^2
3 = 300/x^2
3x^2 = 300
x^2 = 100
x = 10
Now that we have x, we plug this into the different equations for height and base:
Base=(10) + 2 = 12
Height=3 + 150/(10) =3+15 = 18
Hope this helps!
I MARK BRAINLYYYYYYYYYYYYYYYYYYY
Read this stanza from "The Raven" by Edgar Allan Poe.
Once upon a midnight dreary, while I pondered, weak and weary,
Over many a quaint and curious volume of forgotten lore—
While I nodded, nearly napping, suddenly there came a tapping,
As of some one gently rapping, rapping at my chamber door.
"'Tis some visitor," I muttered, "tapping at my chamber door—
Only this and nothing more."
How does what happens in this stanza propel the action in the poem?
It introduces the story and sets up the coming events.
It establishes why Lenore has left the speaker alone.
It resolves the main conflict of the story.
It gives the speaker a reason to speak to the raven.
first of all I HAVE READ THIS POEM ABUNCH OF TIMES, so ur lucky. the first is that there is a person that is weak and then there is a noise and so basically its like a he is doing his business and something bothers the dude

d
Step-by-step explanation:
first do the x, you see x^2-8x so you first want to do (x-4)^2. But then you will see we have created an +16 so wee -16 and then we get (x-4)^2+y^2-9. There is no y to the first power term, therefore you choose d after moving 9 to the Right hand side.
Solve for x in the diagram below.
3xº
75°
Answer:
x = 35°
Step-by-step explanation:
A flat line = 180°
Knowing that, we can make an equation:
3x + 75 = 180
Now, solve:
3x + 75 = 180
- 75 - 75
3x = 105
x = 35
Hope this helps :)
Answer:x=35
Step-by-step explanation:180-75=105
105/3=35
