A sample of gas stored at ST has a volume of 3.56 L. The gas is heated to 400 K and has a pressure of 125 kPa. What is the volume of the gas after it is heated?
Answers
The volume of the gas after it is heated is approximately 0.0417 liters.
To find the volume of the gas after it is heated, we can use the combined gas law, which relates the initial and final conditions of a gas sample. The combined gas law is expressed as:
(P₁V₁) / T₁ = (P₂V₂) / T₂
Where:
P₁ and P₂ are the initial and final pressures of the gas (in kPa)
V₁ and V₂ are the initial and final volumes of the gas (in liters)
T₁ and T₂ are the initial and final temperatures of the gas (in Kelvin)
Given:
Initial volume (V₁) = 3.56 L
Initial temperature (T₁) = ST (which is typically 273.15 K)
Final temperature (T₂) = 400 K
Final pressure (P₂) = 125 kPa
Now we can plug these values into the combined gas law equation and solve for V₂:
(P₁V₁) / T₁ = (P₂V₂) / T₂
(1 * 3.56) / 273.15 = (125 * V₂) / 400
(3.56 / 273.15) = (125 * V₂) / 400
Cross-multiplying and solving for V₂:
3.56 * 400 = 273.15 * 125 * V₂
1424 = 34143.75 * V₂
V₂ = 1424 / 34143.75
V₂ ≈ 0.0417 L
As a result, the heated gas has a volume of approximately 0.0417 litres.

Ali, Basti and Cian stand at three points A, B and C respectively. Suppose that the measure of angle ABC is 50 degrees , the measure of angle BAC is 60 degrees and Ali is exactly 150 ft away from Basti. Find the distance between Basti and Cian.
Answers
To find the distance between Basti and Cian, we can use the law of sines in triangle ABC. The law of sines states that the ratio of the length of a side to the sine of the opposite angle is constant for all sides and their corresponding angles in a triangle.
Let's label the distance between Basti and Cian as "x". We know that the measure of angle ABC is 50 degrees and the measure of angle BAC is 60 degrees. We also know that Ali is exactly 150 ft away from Basti.
Using the law of sines, we can set up the following equation:
sin(50°) / 150 = sin(60°) / x
To solve for "x", we can rearrange the equation:
x = (150 * sin(60°)) / sin(50°)
Using a calculator, we can evaluate the expression:
x ≈ (150 * 0.866) / 0.766
x ≈ 168.4 ft
Therefore, the distance between Basti and Cian is approximately 168.4 ft.

Angles in parallel lines are formed when two parallel lines intersect with another line known as a transversal. So here ∠y is 40° and ∠z is 140°.
What are the angles over parallel lines?Parallel lines form a pair of angles when cut by a transversal. As a result, corresponding angles are equal, as are alternate interior angles, alternate exterior angles, vertical angles, and the sum of interior angles on the same side of the transversal.We know that sum of angles over a straight line is 180°
So here ∠x + 140° = 180°
So ∠x = 180 - 140
Therefore ∠x = 40°
So in this figure ∠x = ∠y , Since they are corresponding angles are equal.
Therefore ∠y = 40°
So ∠z will be 140° . Since ∠y = 40° its opposite angle will also be 40°.
So ∠z + 40° = 180°
Therefore ∠z = 140°
So the angles ∠y = 40° and ∠z = 140°.

AB is perpendicular to line segment [CF, FH, DH, GH] . If the length of EF is a units, then the length of GH is [a, b, a+b, a-b] units.
Answers
According to the given line segment inofrmation, length of GH is a + 2b units.
What is line segment?
A line segment is a part of a line that is bounded by two distinct endpoints. It is a finite length portion of a straight line that extends from one point to another point, and it is named using its endpoints.
Given that AB is perpendicular to line segment [CF, FH, DH, GH]. Let's call the point of intersection of AB and CF as point P.
Now, we can see that triangle CFP and triangle ABP are similar triangles, since angle P is common and both triangles have a right angle at P. So we can write:
CF / AB = FP / BP
Since AB is perpendicular to CF, we know that AB and CF are opposite sides of a rectangle, so CF = AB. Also, since FP = EF (as both are perpendicular to AB), we can rewrite the above equation as:
AB / AB = EF / BP
which simplifies to:
1 = EF / BP
Therefore, we can conclude that BP = EF.
Now, let's consider the line segment [CF, FH, DH, GH]. We know that CF = AB and FH = DH (since they are opposite sides of the rectangle). Therefore, we can write:
GH = CF + FH + DH
= AB + DH + DH
= AB + 2DH
Let's call the length of DH as b. Then, we can write:
GH = AB + 2b
We were given that EF = a, so we can substitute that in for AB to get:
GH = a + 2b
This means that the length of GH is a + 2b units, which corresponds to the choice (a + b) in the given options.

A researcher compares the effectiveness of two different instructional methods for teaching pharmacology. A sample of 51 students using Method 1 produces a testing average of 81.6. A sample of 76 students using Method 2 produces a testing average of 76.4. Assume the standard deviation is known to be 12.24 for Method 1 and 11.19 for Method 2. Determine the 90% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2. Step 2 of 2 : Construct the 90% confidence interval. Round your answers to one decimal place g.
Answers
Answer:
90% confidence interval is: ( 1.7 to 8.7 )
Step-by-step explanation:
Given the data in the question;
Method 1 Method 2
n₁ = 51 n₂ = 76
x"₁ = 81.6 x"₂ = 76.4
σ₁ = 12.24 σ₂ = 11.19
Lets get the Margin of Error(M.E)
M.E = \(Z_{\alpha /2\) √(σ₁²/n₁ + σ₂²/n₂ )
for 90% confidence interval
∝ = 1 - 0.90 = 0.10
∝/2 = 0.10/2 = 0.05
\(Z_{\alpha /2\) = \(Z_{0.05\) = 1.64
so we substitute
M.E = 1.64 × √((12.24)²/51 + (11.19)²/75 )
M.E = 1.64 × √( 2.9376 + 1.669548)
M.E = 1.64 × √( 2.9376 + 1.669548)
M.E = 3.52
so, for 90% confidence interval for x"₁ - x"₂ will be;
C.I = x"₁ - x"₂ ± \(Z_{\alpha /2\) √(σ₁²/n₁ + σ₂²/n₂ )
= 81.6 - 76.4 ± M.E
= 81.6 - 76.4 ± 3.52
= 5.2 ± 3.52
Lower Limit = 5.2 - 3.52 = 1.68 ≈ 1.7
Upper Limit = 5.2 + 3.52 = 8.72 ≈ 8.7
Therefore; 90% confidence interval is: ( 1.7 to 8.7 )

What is the area of circle?The area of a circle is calculated using the formula A = πr², where "A" is the area of the circle.
We know,
Area of Rectangle = l × w, where l = length and w = width
Area of Circle = \(\pi r^{2}\), where r = radius.
find the area of the rectangle,
length = 6 in and width = 4 in
Area of Rectangle = 6 × 4 = 24 inch²
Here given the circle radius is 1 inch, and we use π as 3.14
Area of Circle = \(\pi r^{2}\)
Area of Circle = 3.14 × 1² = 3.14 in²
The area of the shaded region as per figure below is:
Area of the shaded region = Area of Rectangle - Area of Circle
Area of the shaded region = 24 - 3.14 = 20.86 in²
Therefore, the answer is D. 20.86 square inches.
