Answer:
The first increase was of 60%.
Step-by-step explanation:
The initial value of the product is x.
The first increase was of y.
The second increase is of 25%, that is, 1.25.
The final price was double the original, so 2x.
This situation can be modeled by the following equation:
[tex]xy(1.25) = 2x[/tex]
We want to find y.
Simplifying by x
[tex]1.25y = 2[/tex]
[tex]y = \frac{2}{1.25}[/tex]
[tex]y = 1.6[/tex]
After the first increase, the value was 1.6 of the original value, that is a increase as a percent of (1.6 - 1)*100 = 60%.

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.

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!

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?

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

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
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

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?

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

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
