Based on the calculations, the pressure of this gas sample at 27°C is equal to 0.17 atm.
How to determine the final pressure.In order to calculate the final pressure of an ideal gas at constant volume, we would apply Gay Lussac's law.
Mathematically, Gay Lussac's law is given by this formula;
[tex]P\;\alpha \;T\\\\P=kT[/tex]
Where:
P is the pressure.T is the temperature.k is the constant of proportionality.Substituting the given parameters into the formula, we have;
[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2} \\\\\frac{0.80}{127} =\frac{P_2}{27} \\\\0.0063 =\frac{P_2}{27}\\\\P_2 = 0.0063 \times 27[/tex]
Final pressure = 0.17 atm.

From a point 54.0 feet from the base of a flagpole, the angle of elevation to the top of the flagpole is 68.5°. find the height of the flagpole.
The flagpole forms a right-triangle with its base and its top
The height of the flagpole is 137.1 feet
How to determine the height?To determine the height, we make use of the following tangent trigonometry ratio
[tex]\tan(68.5) = \frac{h}{54.0}[/tex]
Where:
h represents the height of the flagpole.
So, we have:
[tex]h = 54.0 * \tan(68.5)[/tex]
Evaluate
[tex]h = 137.1[/tex]
Hence, the height of the flagpole is 137.1 feet

Consider the net of a triangular prism where each unit on the coordinate plane represents four feet. If a sheet of plywood measures 4 ft x 8 ft, how many sheets of plywood will a carpenter need to build the prism?
Answer:
Explanation:
2 sheets of plywood will be needed.
Step-by-step explanation:
See the attached diagram.
Each three square plywood has area 1 units by 3 units = 4 feet by 12 feet = 48 feet square. {Since each unit on the coordinate plane represents four feet}
Now, the two triangular plywood has area half of a unit square area.
So, two triangular plywood has total area = 1 unit by 1 unit = 4 feet by 4 feet = 16 feet square.
Therefore, the total area of plywood required to make the triangular prism is (48 + 16) = 64 feet square.
Now, if a sheet of plywood measures 4 ft by 8 ft i.e. 32 feet square, then the carpenter will need such sheets of plywood. (Answer)

A parking lot in the shape of a trapezoid has an area of 12,052.1 square meters. the length of one base is 82.4 meters, and the length of the other base is 108.6 meters. what is the width of the parking lot?
Answer:
When you solve for the area of a trapezoid, you have this formula:
A = ((a + b)/2) * h
where: a & b are the bases ; h is the height
We just plug in the figures on the formula to get the needed information.
A = 12,052.10 square meters
a = 82.4 meters
b = 108.6 meters
12,052.10 = ((82.4 + 108.6)/2) h
12,052.10 = 191/2 * h
12,052.10 = 95.5 * h
12,052.10 / 95.5 = h
126.2 = height
The height of the parking lot is 126.20 meters.

An example of 9-5 practice question on quadratic equations by completing the square is 5x2–2x−9=0.
What are quadratic equation?This is known to be a type of algebraic expression that is based on the second degree in x. The quadratic equation often exist in a standard form such as ax2 + bx + c = 0.
To solve for 5x2–2x−9=0
Then you have to rearrange the equation into:
x2−(2/5)x−9/5=0
= x2−(2/5)x=9/5
= (x−(2/10))2−(2/5)2=9/5(here b = 2/5)
= (x−(2/10))2=46/25
Then you take the square root on both sides
= (x−(2/10))=±1.356
Therefore x=1.556 or say −1.156.

What is the volume of the cone? use π ≈ 3. 14. 12. 56 cubic units 18. 84 cubic units 20. 93 cubic units 25. 12 cubic units
Answer:
Explanation:
the following formula is used to find the volume of a cone
V - volume = πr²h/3
where π = 3.14, r - radius and h - height
the height hasnt been directly given
we can find height using Pythogoras theorem for the right angled triangle given
4² + h² = 5²
16 + h² = 25
h² = 25 - 9
h² = 9
h = 3
height = 3
diameter is 4, therefore radius - diameter / 2 = 4/ 2 = 2
radius = 2
substituting values in the volume equation
V = 3.14 x 2² x 3 /3
= 12.56
volume is 12.56 cubic units

What are special cases envision algebra 1?
Envision Algebra 1 is one type of course that needs a good background on Pre-algebra functions. It is a type of algebra that starts from Linear Equations up to polynomials and factoring.
To solve for the above question, one has to separate the fraction on one side of the equation. This can be done by subtracting 4 from the two sides of the equation.
So, 3x-1/2 = 9 - 4
3x-1/2 = 5
The you have to multiply the 2 sides by using the denomiator 2 and so it will be:
3x-1 = 5 * 2
3x - 1 - 5 * 2
3x - 1 - 10
