The volume V of an ideal gas varies directly with the temperature T and inversely with the pressure P. cylinder 50 liters contains oxygen at a temperature of 200 K and a pressure of 6 atmospheres , what would the gas pressure be if the volume was changed to 25 liters and the temperature raised to 250 K?
Answer:
15 atm
Step-by-step explanation:
V varies directly with T and inversely with P.
V = kT/P
When T = 200 and P = 6, V = 50.
50 = k (200) / (6)
k = 1.5
When V = 25 and T = 250:
25 = 1.5 (250) / P
P = 15
Given that we know the relation between volume, pressure and temperature (given for the ideal gas), we want to find the change in pressure associated to the given change in volume and temperature.
We will see that the pressure after the change is 15 atm.
Let's see how to solve this problem:
So we start by knowing that the volume depends directly on the temperature and inversely on the pressure, then the relation is something like:
V = k*(T/P)
Where k is a constant.
We know that a cylinder of 50lt is at a temperature of 200K and with a pressure of 6 atm, replacing that in the above equation we get:
50lt = k*(200K/6atm)
With this we can find the value of k:
50lt*(6atm/200K) = k = 1.5 lt*atm/K
Then the equation is just:
V = (1.5 lt*atm/K)*(T/P)
Now the problem says that the volume is 25lt and the temperature is 250K, replacing that in the equation we get:
25lt = (1.5 lt*atm/K)*(250K/P)
Solving for P we have:
P = (1.5 lt*atm/K)*(250K/25lt) = 15atm
Concluding, the pressure is after the change is 15 atm

Jocelyn is going to invest in an account paying an interest rate of 2.3% compounded
continuously. How much would Jocelyn need to invest, to the nearest hundred
dollars, for the value of the account to reach $550 in 15 years?
9514 1404 393
Answer:
$400
Step-by-step explanation:
The formula for the value of an account with interest rate r compounded continuously for t years is ...
A = Pe^(rt)
We want to find P when A = 550, r = .023, and t = 15.
550 = Pe^(0.023·15) ≈ 1.41199P
P = 550/1.41199 = 389.52 ≈ 400
Jocelyn would need to invest about $400 to reach $550 in 15 years.

Let f(x) = 5x - 10 and g(x) = x2 - 7. Find f(g(8)).
Answer:
275
Step-by-step explanation:
g(x) = x²-7 ⇒ g(8) = 8² - 7 =57
f(x) = 5x -10 ⇒ f(g(8)) = f(57) = 5.57-10 = 275
Answer:
275
Step-by-step explanation:
First, find g(8).
g(x) = x^2 - 7
g(8) = 8^2 - 7
g(8) = 64 - 7
g(8) = 57
Now find f(g(8)).
f(x) = 5x - 20
f(g(8)) = f(57)
f(57) = 5(57) - 10
f(57) = 285 - 10
f(57) = 275
Answer: f(g(8)) = 275
Triangle Z prime is the image of triangle Z after a series of transformations.
On a coordinate plane, triangle Z has points (0, 2), (2, 6), (4, 2). Triangle Z prime has points (negative 2, 3), (negative 1, 5), (0, 3).
Aliyah and Ivan described the sequence of transformations in different ways.
Aliyah’s Sequence
Ivan’s Sequence
1. a reflection of triangle Z across the y-axis
2. a dilation by a scale factor of One-half with the origin as the center of dilation
3. a translation 2 units up
1. a dilation of triangle Z by a scale factor of One-half with the origin as the center of dilation
2. a translation of 2 units up and 2 units to the left
Which sequence or sequences are correct and why?
Only Aliyah is correct. A dilation and translation alone could not produce triangle Z prime .
Only Ivan is correct because the dilation must be the first step in the sequence.
Both Aliyah and Ivan are correct because both chose the correct scale factor for the dilation and both describe other transformations that would produce triangle Z prime.
Neither Aliyah nor Ivan is correct because the scale factor they chose for the dilation is incorrect.

The cost c in dollars to rent a surfboard is proportional to the number of hours H it cost you $30 to rent a surfboard for five hours this situation is c equals
Answer:
c = 6H
Step-by-step explanation:
This is a question showing that there is a direct variation between the cost, c, and hours, H.
So that;
c ∝ H
∝ is the proportionality sign
c = kH
where k is a constant of proportionality.
Thus, given that c = $30 and H = 5 hours, then;
30 = k x 5
30 = 5k
Divide both sides by 5 to have;
k = [tex]\frac{30}{5}[/tex]
k = 6
For this situation, since k = 6; then,
c = 6H

I need an answer! Madison Middle School sells rolls of wrapping paper to raise money for student activities. The school gets half of all sales, minus $300 for prizes to top sellers. What is the total sales if the school earns $5000?
Answer:
$10,600 worth of wrapping paper
Step-by-step explanation:
Let the total sales for wrapping paper be represented by variable x
Amount the school keeps is half of total sales x, minus $300. Written as an equation, that would be ; 0.5x - 300
If the schools wants to earn $5000, this amount would be equal to the above equation of what it keeps;
0.5x - 300 = 5000
add 300 to both sides;
0.5x = 5000+300
0.5x = 5300
divide both sides by 0.5 and solve for x;
x=5300 / 0.5
x= 10,600
Therefore, they need to sell $10,600 worth of wrapping paper.
