rv=1/c+r solve for c
I know the answer I'm confused as to how to get there
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

7 pipes fill a tank in 50 minutes. How many minutes does it take if there are 11 pipes?
Give your answer to the nearest minute.
Answer: With 11 pipes, you need 31.82 minutes to fill the tank.
Step-by-step explanation:
Let's define R as the rate at which one single pipe can fill a tank.
We know that 7 of them can fill a tank in 50 minutes, then we have the equation:
7*R*50min = 1 tank
Whit this equation, we can find the value of R:
R = 1 tank/(7*50min) = (1/350) tank/min.
Now that we know the value of R, we can do the same calculation but now with 11 pipes.
Then the time needed to fill the tank, T, is such that:
11*(1/350 tank/min)*T = 1 tank
We need to isolate T.
T = 1 tank/(11*(1/350 tank/min)) = 31.82 min
With 11 pipes, you need 31.82 minutes to fill the tank.
what is the slope of the line please help khan academy??
Answer: The answer is -3
Step-by-step explanation:
The graph goes down 3 and over 1, since slope is written rise/run, it would be -3/1, which reduces to -3
If you were a colonist in the mid-1770s would you have stood with the Patriots or the Loyalists? Write an argumentative essay in which you support your position. Use evidence from the information provided as well as your background knowledge in U.S. history to support your claim and counterclaim.
Answer:
I would have stood with the patriots because British soldiers forcefully entered their homes. They also ramped up taxes over a petty war with France because they couldnt pay it themselves.
The Loyalists were brainwashed to the British king, because they were rich and privileged. So they could pay the very high taxes. This meant these guys didn't actually know how the people felt.
The British also ramped up the price of tea, which the colonists loved, just to be petty because the Patriots did not want to be taxed. Back then, the British were very petty. Now they're just jaded.
But back to the essay: The Patriots had a good cause. They wanted to move on from something chaining them down. The Loyalists did not. And I would want to happily tar some tax collectors. Wouldn't you?

Wyatt is saving up to buy a new bicycle. He already has $60 and can save an
additional $6 per week using money from his after school job. How much total money
would Wyatt have after 6 weeks of saving? Also, write an expression that represents
the amount of money Wyatt would have saved in w weeks.
Answer:
Expression: 6w+$60 Money: $99
Step-by-step explanation:
So, let's find the ammount for 6 weeks
We know he can make $6 per week, so we ned to multiply 6*$6 to get your answer
So, 6 ( weeks ) * 6 ( dollars) = $36 for 6 weeks
Then, we ned to add the $60 he already has saved up, so $60+$39=$99
For the equation, We know that we need to multioply the number of weeks by 6, as shown by how we solved the last problem
So, 6*w=6w
Then we need to add $60
So, we get 6w+$60 for the expression

The following data are the distances between a sample of 20 retail stores and a large distribution center. The distances are in miles. 29; 31; 34; 40; 58; 67; 68; 69; 76; 80; 82; 95; 96; 96; 99; 106; 112; 127; 145; 150 Find the value that is one standard deviation below the mean. (Round your answer to one decimal place.)
Answer:
47.8
Step-by-step explanation:
Given the data:
29; 31; 34; 40; 58; 67; 68; 69; 76; 80; 82; 95; 96; 96; 99; 106; 112; 127; 145; 150
Mean (m) = ΣX / n
n = sample size
ΣX = 1660
Mean = 1660 / 20
Mean (m) = 83
Standard deviation(s) : √(Σ(X - m)² / n-1)
Σ(X - m)² = (29-83)^2 + (31-83)^2 + (34-83)^2 + (40-83)^2 + (58-83)^2 + (67-83)^2 + (68-83)^2 + (69-83)^2 + (76-83)^2 + (80-83)^2 + (82-83)^2 + (95-83)^2 + (96-83)^2 + (96-83)^2 + (99-83)^2 + (106-83)^2 + (112-83)^2 + (127-83)^2 + (145-83)^2 + (150-83)^2
√(23608 / (20-1))

Suzi starts her hike at 275 feet below sea level. When she reaches the end of the hike, she is still below sea level at −135 feet. What was the change in elevation from the beginning of Suzi's hike to the end of the hike?
Answer:
Have a nice day!
Step-by-step explanation:
Answer:
140
Step-by-step explanation:
Hi there!
This problem may seem tricky because of the negative sea level, os let’s set up an equation.
[tex]-275+x=-135[/tex] where x = the change in elevation.
Using orders of operations, add 275 to both sides and you will end with
x = 140
Her change in elevation is 140 feet.

The ellipse with center C(2, -3), vertices V(-8,-3) and V2(12,-3), and foci F1(-4,-3) and F2(8,-3). 6.
The ellipse with vertices V.(-1,-4) and V2(-1,6), and foci F(-1,-3) and F2(-1,5).
Answer:
(x-2)²/100 + (y+3)²/64 = 1
Step-by-step explanation:
C (2,-3): h=2 k=-3
semimajor axis (CV): a=12-2=10
center-foci: c=8-2=6
semi minor axis: b² = a²-c²= 100 - 36 = 64
equation: (x-h)²/a² + (y-k)²/b² = 1
(x-2)²/100 + (y+3)²/64 = 1

The perimeter of a yard is 60 meters. The length is six less than twice the width. What are the dimensions of the yard?
Length = 18 meters,
Width = 12 meters
B
Length = 36 meters,
Width = 24 meters
C
Length = 24 meters,
Width = 36 meters
D
Length = 12 meters,
Width = 18 meters
Answer:
Length = 18 meters,
Width = 12 meters
Step-by-step explanation:=
Step one:
given data
perimeter= 60 meter
let the width be x
W=x
L=(2x-6)
Step two:
we know that perimeter of a rectangle is given as
P=2W+2L
60=2x+2(2x-6)
60=2x+4x-12
60=6x-12
collect like terms
6x= 60+12
6x=72
divide both sides by 6
x=72/6
x=12
Width is 12m
from L=(2x-6)
L=2*12-6
L=24-6
L=18m
8. Have you ever heard the word tithe? It means a tenth or 10%. Leviticus 27:30 reads, "A tithe of
everything from the land, whether grain from the soil or fruit from the trees, belongs to the LORD;
it is holy to the Lord." Therefore, we see in the previous question that Nick's youth group was
able to save more than 10% and in return they donated the money. In your opinion, why does
God require us to give 10% back to Him and what does that look like for you?

what is the distance, in units, between the y-intercept of f(x) = x^2 +7x - 18 and the y-intercept of the linear function that passes through the points shown on the table below
x g(x)
-5 2
10 11
25 20
60 41
Answer:
13
Step-by-step explanation:
f(x) = x² +7x - 18
y interception: x=0 y = -18 (0 , -18)
line g(x): --- the data of (60,47) to make a linear function
y = mx + b
m = (11-2) / (10 - -5) = 9/15 = 0.6
b = mx - y = 0.6 * (-5) - 2 = - 5 ... y intercept: (0 , -5)
distance between 2 y intercept: 18-5 = 13
y = 0.6x - 5
Answer:
23
Step-by-step explanation:
f(x) (y intercept ) = -18
g(x) (y intercept) = 5
difference so f(x)-g(x)
-18-5 = -23
the answer cannot be negative

11. Kelsey's garden on her farm was originally 20 feet long and 4 feet wide. She added
an addition onto her garden that was 12 feet long and 6 feet wide. If she wants to
use 100 square feet of the gardens total area to plant vegetables and the rest of the
area to plant fruits, how much space of the garden will the fruit plants take up?
Answer:
So, the original space of her garden was 20ftl + 4ftw. This makes her garden have a starting area of 80ft.
She then adds another 72ft (12ftl x 6ftw) which brings the total area to 152ft.
We have 152ft to work with here, if she wants to use 100 of those ft for vegetables, and the rest to plant fruits, we have to subtract 100 from 152 which gives us 52.
Answer:
The Fruits will take up 52ft of land.
Hope this helped!
