In physics, the Ideal Gas Law describes the relationship among the pressure, volume, and temperature of a gas sample. The law is represented with the formula PV = nRT, where P is the pressure, V is the volume, T is the temperature, n is the amount of gas, and R is a physical constant. Select all the equations that are equivalent to the formula PV = nRT. Group of answer choices

The temperature in degrees Kelvin is 273 degrees less than the temperature in degrees Celsius. Use the formula C = 5/9(F - 32) to write a formula for the temperature in degrees Fahrenheit F in terms of the temperature in degrees Kelvin K. A. F = 9/5(K - 273) - 32
B. F = 5/9(K + 273) + 32
C. F = 9/5C + 32
D. F = 9/5(K + 273) + 32
Also Please Answer My other Question I posted
Answer:
1. D and C
2. F = 9/5(k-273) + 32
Step-by-step explanation:
1. We simply want to write the given equation in different forms;
PV = nRT
So P = nRT/V
R = PV/nT
V = nRT/P
n = PV/RT
T = PV/nR
So the correct expressions are;
D, C,
2. we want to make F the subject of the formula, that would be;
C = 5/9(F - 32)
9C = 5(F - 32)
divide both sides by 5
9C/5 = F - 32
F = 9C/5 + 32
But K = C + 273
So C = K - 273
Insert this into the equation, we have
F = 9(K-273)/5 + 32

1. The weights of 20 year old vegetarian women are normally distributed with a standard deviation σ = 15 pounds. How large of a sample would be need to estimate the mean weight μ of 20 year old vegetarian women with a margin of error of 5 pounds with 95% confidence?
Answer:
34.5744 ≈ 35
Step-by-step explanation:
The formula for Margin of Error
= z × σ/√n
Where
z = z score of the confidence interval = z score of 95% = 1.96
σ = 15 pounds
n = number of samples = ??
Margin of Error = 5
Hence,
5 = 1.96 × 15/√n
Cross Multiply
5 × √n = 1.96 × 15
Divide both sides 5
√n = 1.96 × 15/5
√n = 1.96 × 3
√ n = 5.88
Square both sides
n = 5.88²
n= 34.5744
Approximately the size = 35

Step-by-step explanation:
The mean cost to repair the smoke and fire damage that results from home fires of all causes is $11,389 (HomeAdvisor website, December 2014). How does the damage that results from home fires caused by careless use of tobacco compare? The DATAfile named TobaccoFires provides the cost to repair smoke and fire damage associated with a sample of 55 fires caused by careless use of tobacco products. Using past years' data, the population standard deviation can be assumed known with σ = $3,027.
Answer:
The alternative is characterized in the interpretation section following the table, as per the case mentioned.
Step-by-step explanation:
According to the question:
The sample mean will be:
⇒ [tex]\bar{x}=\frac{\Sigma x}{n}[/tex]
[tex]=\frac{1050500}{55}[/tex]
[tex]=19100[/tex]
The critical value of z ([tex]z_e=1.96[/tex]) seems to be the 95 % confidence interval. So the required confidence interval will be:
= [tex]\bar{x} \ \pm \ x_{critical}\frac{\sigma}{\sqrt{n} }[/tex]
= [tex]19100 \ \pm \ 1.96.\frac{3027}{\sqrt{25} }[/tex]
= [tex]19100 \ \pm \ 800[/tex]
Consequently, the average cost of repairing flames and smoke injury can outcomes from household fires started by careless tobacco is therefore estimated at quite a 95 percent confidence interval ($18300, $19900). The 95 percent confidence interval indicates that the average estimated price of fires results through the use of tobacco is somewhat more costly than that of the average cost of flames results from across all factors that cause.The 95% confidence interval is ($18300 , $19900) and according to the confidence interval, the average estimated price of fires results through the use of tobacco is somewhat more costly than that of the average cost of flames results from across all factors that cause.
Given :
The mean cost to repair the smoke and fire damage that results from home fires of all causes is $11,389.Sample size, n = 55.The population standard deviation can be assumed known with σ = $3,027.First, find the sample mean by using the following formula:
[tex]\rm \bar{x}=\dfrac{\sum x}{n}[/tex]
[tex]\rm \bar{x}=\dfrac{1050500}{55}[/tex]
[tex]\rm \bar {x} = 19100[/tex]
Now, for 95% confidence level, the confidence interval will be:
[tex]= \rm \bar{x} \pm x_{critical} \dfrac{\sigma}{\sqrt{n} }[/tex]
[tex]\rm = 19100\pm 1.96\times \dfrac{3027}{\sqrt{55} }[/tex]
[tex]=19100\pm 800[/tex]
The 95% confidence interval is ($18300 , $19900).
According to the confidence interval, the average estimated price of fires results through the use of tobacco is somewhat more costly than that of the average cost of flames results from across all factors that cause.

Philip is allowed to watch 2 hours of television each day Monday through Thursday and 4 hours of television each day Friday through Sunday. Which of the following equations can be used to calculate the number of hours of television Philip is allowed to watch in x weeks?
Answer:
x(4 × 2) + x(3 × 4)
Step-by-step explanation:
The question says "which of the following equations" which infers you have already been given options. However, none were provided in the question so my answer may be slightly different than the given options as there's several ways to solve this problem.
Monday through Thursday = 4 days × 2 hours per day
Friday through Sunday = 3 days × 4 hours per day
To find the total for one week, add the two expressions together:
(4 × 2) + (3 × 4)
The question states for "x weeks" so:
x(4 × 2) + x(3 × 4)
This is one way the equation can be written
Another way is:
x[(4 × 2) + (3 × 4)]
If neither of these are answers for your mutliple choice question, then please provide the options and I will let you know which is correct

The right triangle on the right is a scaled copy of the right triangle on the left. Identify the scale factor. Express your answer as a whole number or fraction in simplest form.
Please help me 22 points and a THANK YOU WITH 5 STAR RATING:))))
Answer:
Scale factor = [tex] \frac{5}{4} = 1\frac{1}{4} [/tex]
Step-by-step explanation:
The scale factor is how much the right triangle on the right was increased in size or enlarged, since the right triangle is a scaled copy of the one on the left.
The scale factor used = the ratio of any of their corresponding sides
Scale factor = side length of the ∆ on the right ÷ corresponding side length of the ∆ on the left
Scale factor = [tex] \frac{15}{12} [/tex]
Scale factor = [tex] \frac{5}{4} = 1\frac{1}{4} [/tex]
The scale factor expressed as a fraction is 4/5
Since the right triangle on the right is a scaled copy of the right triangle on the left, then the ratio of their similar sides is equal to the scale factor.
This is expressed as:
Taking the ratio of the fractions
[tex]\frac{20}{25} = \frac{4}{5}[/tex]
Similarly for [tex]\frac{12}{15}[/tex]
[tex]\frac{12}{15} =\frac{4}{5}[/tex]
This shows that [tex]\frac{20}{25} = \frac{12}{15} = \frac{4}{5}[/tex]
Hence the scale factor expressed as a fraction is 4/5

The area of the triangle is 10 square units, the correct option is B.
What is a Triangle?A triangle is a polygon with three sides, angles, and vertices.
The triangle is classified into various types on the basis of the angle and on the basis of equality of the length of the sides.
The vertices of the triangle are at:
(-3,3), (2, 3), and (4,7).
The area of the triangle has to be determined.
The length of the sides will be calculated using the distance formula.
side 1 = [tex]\rm \sqrt { (3-3)^2 + ( 2 +3)^2}[/tex] = 5 units
side 2 = 2√5 units
side 3 = √65 units
The height of the triangle is determined by calculating the distance from (4, 7) to (4, 3).
The height of the triangle = 4 units
The area of a triangle is given by,
A = (1/2) * base * height
A = (1/2) * 5 * 4
A = 10 square units
