Answer:
rv=1/2
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
Given
rv=1/c+rSolving for c
Its not clear what the denominator is: c or c+r so doing bothDenominator is c:
rv = 1/c + r1/c = rv - rc = 1/(rv - r)Denominator is c + r:
rv = 1/(c + r)rv(c + r) = 1rvc + r²v = 1rvc = 1 - r²vc = (1 - r²v)/rvor more simplified
c = 1/rv - rNote. If you know the answer it should help how to get it

What percentage of the shape is orange?
Write your answer using a percent sign (%).
(help!) almost done!! I will mark who ever awnser s first as brainliest!
Answer:
40%
Step-by-step explanation:
There are five pieces of a square. Two of the five pieces are shaded in orange, since each piece is 20% and there are two shaded pieces, it is your best bet that your final answer is 40%.
Answer:
40%
Step-by-step explanation:
Since there are only two boxes filled, the fraction would be 2/5. Now, by applying that knowledge, you can see that the bow is filled 40% of the way with orange. An easy way to figue this out would be to divide 2 by 5 and get the decimal of .4 which as a percentage would be 40%. Hope this helped!
3. Which situation could be solved using the equation -4 + 4 =0?
a) Teanni has $4 in her lunch account. She deposits $4 in her account when she gets to school.
b) Amanda recorded a temperature of -4°F at 8:00am. An hour later, the temperature
increased by 4°F.
c) Melany walks 4 blocks towards her home and stops at the store. She walks the remaining 4
blocks home.
d) Joshua places 4 counters, each representing -1, in a group. He creates a total of 4 identical
groups.
Answer:
b because -4°F plus 4°F would be 0°F
HELP ME PLEASE I REALLY NEED HELP!!!!
Answer:
x = 5
Step-by-step explanation:
[tex]\frac{x}{2x - 3} = \frac{10}{14}[/tex] --> Triangle Proportionality Theorem
10(2x - 3) = 14(x) --> Cross Multiplying
20x - 30 = 14x --> Distributing 10 and 14 to the parentheses
20x -30 - 14x + 30 = 14x - 14x + 30 --> Subtracting 14x and adding 30 on both sides
6x = 30 --> Simplifying
6x/6 = 30/6 --> Dividing 6 on both sides
x = 5 --> Simplifying
Hope this helped!
By the way, I'm not so sure you understand the concept of "Triangle Proportionality Theorem" since you asked a similar one before that. So I'll post an image that I found on the internet that explains it. :D

Answer:
B (rate of change), D (y-intercept)
Step-by-step explanation:
a) The rate of change is found by solving for y. It is the x-coefficient:
4y = -x +12
y = -1/4x +3 . . . . divide by 4
The rate of change is -1/4.
__
b) The rate of change can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (10 -4)/(2 -(-2)) = 6/4 = 3/2
The rate of change is 3/2.
__
c) The rate of change can be found by counting grid squares. The line goes down 1 square for each square to the right. The rate of change is ...
m = rise/run = -1/1 = -1
The rate of change is -1.
__
d) The rate of change is 0.5, the amount paid per box.
__
Of the rates -1/4, 3/2, -1, 0.5, the largest rate of change is 3/2 in relationship B.
_____
a) The y-intercept is the constant in the slope-intercept form equation: +3.
__
b) The y-intercept can be found from the point-slope form equation using the slope we found.
y -4 = 3/2(x +2)
y = 3/2x +3 +4
y = 3/2x + 7
The y-intercept is 7.
__
c) The y-intercept is 4, where the line crosses the y-axis.
__
d) The y-intercept of a proportion is 0.
__
Of the y-intercepts 3, 7, 4, 0, the least y-intercept is 0, in relationship D.
Is a dilated segment still a segment ?
Answer:
Still a segment
Step-by-step explanation:
When a segment is dilated by a scale factor of r = 1, then the segment and its image would be the same length. When the points P and Q are on a line containing the center, then the dilated points P' and Q' will also be col linear with the center producing an image of the segment that is a segment.

The length of the rectangle is three meters less than twice the width. The perimeter is 36meters. What’s the demensions of the rectangle
Answer:
L= 11m
W= 7m
Step-by-step explanation:
Step one:
given data
Let the width W= x
Length = (2x-3)
P= 36 m
Required
The perimeter
P= 2L+2W
36= 2(2x-3)+ 2x
36= 4x-6+2x
collect like terms
36+6= 6x
42= 6x
divide both side by 6
x= 7
the width is 7 m
the length = 2x-3= 2*7-3= 14-3= 11 m

800 adults were surveyed to find out how many notes per week they cook dinner 60% indicated that they cooked dinner more than four nights at per week based on the results of the survey how many adults out of a group of 2000 to cooked dinner more than four nights per week
Answer:
1200
Step-by-step explanation:
60 x
- = -
100 800
There are 2 ways to solve this.
1) 800 x 60= 48,000
Divide by 100= 480
x=480
2) Multiply 60 by 8.
Now there are another 2 ways to go.
1) 480 x
- = -
800 2000
OR2) 60 x
- = -
100 2000
I recommend the second option for both. It is easier. The second option allows you to find and equal ratio, with less of the hassle.To get 2000, 100 must be multiplied by 20. So.... multiply 60 by 20 to get a equal ratio.
Your answer is 1200. Meaning 1200 adults cooked dinner more than four nights per week.
I hope this helps you significantly

HELP ME PLEASE!!!!!!
Help me. I'm really confused!
Answer:
Step-by-step explanation:
Remember, the first point in a bracket like this (6, 1) is the x coordinate. Here, 6 is your x coordinate. So, if we actually had the line (which we don't have right now, it would be lined up with the number 6 on the x axis. And the second point, 1 here, is the y coordinate. Which tells you where this point falls on the y axis. it would be lined up with the number 1 on the y axis. First, let's work on the parts where you are listing the points. it seems to give you the x coordinate 2 on the first one. So on the x axis which is the horizontal line that says Number of Books Sold, go to the number 2. Then y upward with your mouse and the first point that appears with the x coordinate of 2 (it's the 2nd point if you start from the bottom of the line and go up) has the y coordinate of 20 because if you use your mouse to go left on the same gray line that point is on, you will hit 20 on the line that says Total Amount Payed (this is your y axis). Now, on the next point it just gives you the y coordinate, 40. Which means that it should be on the grey line that hits the number 40 on the Total Amount Payed line (your y axis). So if you find that point and go down with your mouse on the gray line right under it, you should hit 4. So that point is (4, 40). 6 is not labeled but it is the gray line after the 5 on the x axis. If you go up 6, you hit the to right corner of the graph and if you trace it to the y-axis, it's not labeled but it should be 60 because if you pay attention, the numbers on the y-axis are going up by 10s. The x coordinate represents The Number of Books Sold because it says that under the x axis. The y coordinate represents the Total Amount Payed (dollars). ordered pairs are like ratios because they are both pairs. Ordered pairs tell you how much to go up, down, forwards, and backwards on a coordinate plane while ratios tell you a proportion. I am including a picture to help you out. I hope this made sense and was helpful!
