Find the midpoint of the segment with endpoints at A(3, 11) and B(7,3).
(5,7)
(7,5)
(3,9)
(9,3)
Answer:
The answer is
(5,7)Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A(3, 11) and B(7,3)
The midpoint is
[tex]M = ( \frac{3 + 7}{2} \: , \: \frac{11 + 3}{2} ) \\ = ( \frac{10}{2} \: , \: \frac{14}{2} )[/tex]
We have the final answer as

Solve for the variable. Show all work. |-3 + k| = 10
Answer:
[tex]k=13\text{ or } k=-7[/tex]
Step-by-step explanation:
So we have the equation:
[tex]|-3+k|=10[/tex]
Definition of Absolute Value:
[tex]-3+k=10\text{ or } -3+k=-10[/tex]
Add 3 to both sides for both equations:
[tex]k=13\text{ or } k=-7[/tex]
And we're done!
Answer:
K=13
Step-by-step explanation:
|-3+k|=10 this is an equation with absolute value
add 3 on both sides
k=13

Hannah pays $39 per month for her cellular phone which includes 1 hour of use.
After the first hour, she pays 20% per minute. How much will her monthly bill be
if she uses her phone 2.5 hours?
Answer:
$57
Step-by-step explanation:
1h = $39
so the first hour costs $39
2.5h -1h =1.5h=90mins
0.20x90=18
so 1h30mins after the initial 1h cost $18
so all together it costs $18+$39= $57
What is the scale factor of 7/2?
its 6 Step-by-step explanation:
The scale factor of the drawing of the house given the scale of the drawing is 1cm : 0.29m.
What is the scale factor?A scale drawing is a smaller image of a larger image or object. The scale drawing is usually reduced at a constant dimension.
The scale factor is the ratio of the dimension of the scale drawing to the original object. The scale factor is the measurement used to convert the larger image into a smaller version of the original object.
The scale factor is usually written in this format - 1, a colon (:), then the matching length on the original image. e.g. 1 : 10
The scale factor of the drawing = original dimensions/dimensions of the scale drawing
2 / 7 = 0.29
The complete question is given below.

READING Etu has read 12 of the 32 chapters in his assigned book. He
plans to finish the book by reading c chapters each for 8 days until the
book is due. Which equation best represents the situation?
A. 12 - 8c = 32
B. 12 + g = 32
C. 12 + 8C = 32
D. 12 - Q = 32
Answer:
12 +g=32
Step-by-step explanation:
32 chapters
12 chapters read
-------
20 chapters must read
=>
12+g =32
g=32 - 12
g=20
The equation that best represents the situation will be 12 + 8c = 32
Based on the information, Etu has read 12 of the 32 chapters in his assigned book and he plans to finish the book by reading c chapters each for 8 days until the book is due.
Therefore, the equation that best represents the situation based on the information will be 12 + 8c = 32

Find the length of the given segments and determine if they are congruent Simplify DE and RS
Answer:
The answer is below
Step-by-step explanation:
The complete question is contained in the image.
The distance between points [tex]A(x_1,y_1)[/tex] and [tex]B(x_2,y_2)[/tex] in the coordinate plane is given as:
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Point D is at (7, 0) and E at (0, -2) hence the distance between the two points is:
[tex]|DE|=\sqrt{(0-7)^2+(-2-0)^2}=\sqrt{49+4}=\sqrt{53}=7.28[/tex]
Point R is at (-7, -7) and S at (3, -3) hence the distance between the two points is:
[tex]|RS|=\sqrt{(3-(-7))^2+(-3-(-7))^2}=\sqrt{100+16}=\sqrt{116}=10.77[/tex]
Since |RS| ≠ |DE|, therefore they are not congruent
find the midpoint of the line using the midpoint formula.

A store sells two brands of hand lotion. Brand X costs $3.25 for 5 fluid ounces.
Brand Y costs $6.00 for 8 fluid ounces. How much less per fluid ounce does
Brand X cost than Brand Y? Show your work.
Answer:
[tex]\frac{3,25}{5}=0,65 \\[/tex] for brand x for 1 fluid ounces
[tex]\frac{6}{8}=0,75[/tex] for brand y
0,75-0,65=0,1
Brand x costs $0,1 less
Step-by-step explanation:
Answer:
0.10 less
Step-by-step explanation:
First you need to find how much for one fluid ounce, so for Brand X you would divide 3.25 by 5 to get 0.65 and for Brand Y 6.00 divided by 8 to get 0.75. Now you know how much for 1 ounce of each brand so next you just have to subtract 0.65 (Brand X) from 0.75 (Brand Y) to get that Brand X costs $0.10 less than brand Y.

James is 6 times older than his friend Zach . If Zach added 8 to his age and multiplied this sum by 3 . Write an equation that can be used to solve for zachs age in the box below , use Z as the variable .
Given that:
James is 6 times older than his friend Zach, if Zach added 8 to his age and multiplied this sum by 3 .
To find:
The equation that can be used to solve for zach's age.
Solution:
Let the age of zach be Z.
Zach added 8 to his age = Z+8
And multiplied this sum by 3 = 3(Z+8)
James is 6 times older than his friend Zach = 6Z
Now,
[tex]6Z=3(Z+8)[/tex]
[tex]6Z-3Z=24[/tex]
[tex]3Z=24[/tex]
Divide both sides by 3.
[tex]Z=8[/tex]
Therefore, the required equation is [tex]6Z=3(Z+8)[/tex] is age of zach is 8 years.

3 – 2x] = 5?
(-1, 4)
B. {1, –4]
C. {-1}
D. [4]
Answer:
[C] -1
Explanation:
3 - 2x = 5
Subtract 3 from both sides
3 - 2x - 3 = 5 - 3
Simplify
-2x = 2
Divide both sides by -2
-2x / -2 = 2 / -2
x = -1

The product of 4 and a number plus 17 is 15
Answer:
the answer is -0.5.
Step-by-step explanation: First subtract 17 from 15 to know what u need to get. Know that u get -2, we have to figure out what to do to get -2 out of 4. First to get positive 2, multiply by 0.5, than since we need to get negative 2, add a negative in front. Hence, the answer is -0.5 .
your equation would read
4•x+17=15
so 4 times what plus 17 is 15?
4•-0.5+17=15

s = no of sides
A =120 feet^2
s =?
[tex]A =s^2\\\\120=s^2[/tex]
Square root both sides of the equation
[tex]\sqrt{120} = \sqrt{s^2} \\\\20\sqrt{3} = s\\\\s = 20\sqrt{3} \:or \:34.6[/tex]
Answer:

We are given that BA is perpendicular to BD, so that must mean that m∠ABD is a right angle, or 90º. This means: (8x - 10) + (4x + 52) = 90º, since both of the angles add up to become a right angle. We have to solve for x in order to find m∠CBD.
PART 1
[tex]\bf Step~1:[/tex]
Equation: (8x - 10) + (4x + 52) = 90
Let's add the like values together first.
[tex]\bf 8x+4x=12x\\-10+52 = 42[/tex]
[tex]\bf 12x+42=90[/tex]
[tex]\bf Step~2:[/tex]
Let's subtract 42 from both sides of the equation to isolate the variable we are solving for, x. Our goal is to isolate it completely to get a value that is equal to x.
[tex]\bf12x+42(-42)=90(=42)\\12x=48[/tex]
[tex]\bf Step~3:[/tex]
Divide both sides by 12 to get our final answer for x.
[tex]\bf\frac{12x}{12} =x\\\\\frac{48}{12}= 4\\\\x=4[/tex]
PART 2
Now that we have x, we simply plug it into our equation for m∠CBD.
[tex]\bf Step~1:[/tex]
[tex]\bf4x+52\\4(4)+52[/tex]
[tex]\bf Step~2:[/tex]
Multiply 4 and add 52.
[tex]\bf 4*4=16\\16+52=68[/tex]
[tex]\large\boxed{\bf Our~final~answer: mCBD=68}[/tex]
