SOLUTION:
Step 1:
In this question, we are given the following:
The volume of a gas V held at a constant temperature in a closed container varies inversely with its pressure P. If the volume of a gas is 800 cubic centimeters when the pressure is 450 millimeters of mercury (mm Hg), find the volume when the pressure is 200 mm Hg.
Step 2:
This is an application of Boyle's law which states that:
Boyle’s law is a gas law that states that the pressure exerted by a gas (of a given mass, kept at a constant temperature) is inversely proportional to the volume occupied by it. In other words, the pressure and volume of a gas are inversely proportional to each other as long as the temperature and the quantity of gas are kept constant.
[tex]\begin{gathered} Mathematically,\text{ we have that:} \\ V\text{ }\propto\text{ }\frac{1}{P} \\ Then,\text{ we have that:} \\ V\text{ =}\frac{k}{P}\text{ \lparen where k is a constant \rparen} \end{gathered}[/tex][tex]when\text{ V = 800 cubic centimetres , then P = 450 mm Hg}[/tex][tex]\begin{gathered} 800\text{ =}\frac{k}{450} \\ cross-multiply,\text{ we have that:} \\ \text{k = 800 x 450 = 360,000} \end{gathered}[/tex][tex]\begin{gathered} Then,\text{ the equation connecting V and P =} \\ \text{ V }=\frac{360,000}{P} \end{gathered}[/tex]Next:
[tex]when\text{ P = 200 mm Hg, we have that:}[/tex][tex]\begin{gathered} V\text{ = }\frac{360,000}{200} \\ \text{V = 1800 cubic centimetres } \end{gathered}[/tex]CONCLUSION:
The volume when the pressure is 200 mm Hg is:

The empty boxes of the numerators for the given rational expression is to be filled with 4x and 2 respectively.
What is a rational expression?Rational expression is a division of two polynomials. Which implies that the numerator and denominator of the fraction consists of polynomials.
To solve this, we will first factorise the expression of the denominator as follows;
x² - 9x + 8 = x² - 8x - x + 8
x² - 9x + 8 = x(x - 8) -1(x - 8)
x² - 9x + 8 = (x - 1)(x - 8)
Hence, we can rewrite the rational expression as:
(4x + 2)/[(x - 1)(x - 8)]
we can break the expression further by dividing each term of the numerator with the expression (x - 1)(x - 8) as follows;
(4x + 2)/[(x - 1)(x - 8] = [4x/(x - 1)(x - 8)] + [2/(x - 1)(x - 8)]
Therefore, 4x and 2 will be the appropriate values to be filled in the empty boxes equated to the rational expression.

A rental car company charges $76.50 per day to rent a car and $0.06 for every mile driven. Hunter wants to rent a car, knowing that:
He plans to drive 400 miles.
He has at most $330 to spend.
Use the drop-down menu below to write an inequality representing d, the total number of days Hunter can rent the car while staying within his budget.
The inequality representing d, the total number of days is 76.5d + 24 ≤ 330
How to determine the inequality that represents the scenario?From the question, the given parameters are:
Charges per day = $76.50
Charges per mile = $0.06
This means that the equation that represents the total charges for d days is
Total = Charges per day x Number of days + Charges per mile x Number of miles
So, we have
Total = 76.5 x d + 0.06 x m
Where m represents the number of miles
From the question, we have
He plans to drive 400 miles.He has at most $330 to spend.This means that
m = 400 and Total ≤ 330
So, we have
76.5 x d + 0.06 x 400 ≤ 330
Solve
76.5 x d + 24 ≤ 330
This gives
76.5d + 24 ≤ 330
Hence, the inequality that represents the scenario is 76.5d + 24 ≤ 330

Mai runs around a 400-meter track at a constant speed of 250 meters per minute. How many minutes does it take Mai to complete 4 laps of the track? Write your answer as an improper fraction
The minutes it take Mai to complete 4 laps of the track would be 6 minutes 24 seconds.
What is speed?Speed can be calculated as the ratio of distance traveled to the time taken.
Speed = distance /time
Also, Time = distance/ speed
In this case, the distance is 4 laps of 400 meters, so;
4 x 400=1600 meters
Speed = 250 per minute
Now,
Time =1600 meters /250 meter per minute

Beth is planning a playground and has decided to place the swings in such a way that they are the same distance from the jungle gym and the monkey bars. if beth places the swings at point d, how could she prove that point d is equidistant from the jungle gym and monkey bars? if segment ad ≅ segment cd, then point d is equidistant from points a and b because congruent parts of congruent triangles are congruent. if segment ad ≅ segment cd, then point d is equidistant from points a and b because a point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects. if m∠acd = 90° then point d is equidistant from points a and b because congruent parts of congruent triangles are congruent. if m∠acd = 90° then point d is equidistant from points a and b because a point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects.
The angle bisector theorem states that a triangle's opposite side is divided into two halves by an angle bisector that is proportional to the triangle's other two sides.
A point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects, therefore if mACD = 90°, point D is equidistant from points A and B.
Any point on the perpendicular bisector is simply equal distance from both endpoints of the line segment on which it is drawn, according to the perpendicular bisector theorem.
The answer is that point is equidistant from points A and B because a point on a perpendicular bisector is equidistant from the endpoints of the segment it makes up. Therefore, if a pillar is stationed at the middle of a bridge at an angle, all the points on the pillar will be equidistant from the end points of the bridge intersects.

Algebra, on the other hand, deals with the limitations and guidelines that apply to all other types of numbers, including whole numbers, integers, fractions, functions, and so on. Arithmetic math serves as the foundation for algebra, which always adheres to its definition. A large range of subjects fall within the broad definition of mathematics, which encompasses a very broad range of topics. Beginning with the fundamentals like addition, subtraction, and division of numbers, they then move on to more complicated topics like exponents, variations, sequence, progression, and more. This part does touch on some of the mathematical formulas and mathematical sequence. Four essential mathematical operations—addition, subtraction, multiplication, and division—are covered in basic arithmetic.

Which equation has the solution x = 5? Select each correct answer. Responses
A) 11 + 6x = 22
B) 3x + 1 = 9
C) 18−2x=9
D) 25/x+4=9
E) x/5 + 5 = 6
F) 32−4x=12
The equation that has the same solution as x = 5 are as follows:
25 / x + 4 = 9x / 5 + 5 = 6 32 - 4x = 12 How to solve equation?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
In other words, an equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The equation can be solved as follows:
The equation will have the same solution as x = 5.
Therefore,
25 / x + 4 = 9
subtract 4 from both sides of the equation
25 / x + 4 = 9
25 / x + 4 - 4 = 9 - 4
25 / x = 5
cross multiply
5x = 25
divide both sides by 5
x = 25 / 5
x = 5
x / 5 + 5 = 6
x / 5 = 6 - 5
x / 5 = 1
cross multiply
x = 5
32 - 4x = 12
- 4x = 12 - 32
- 4x = - 20
divide both sides of the equations by - 4
x = -20 / - 4
x = 5
Therefore, the equation with same solution are 25 / x + 4 = 9, x / 5 + 5 = 6 and 32 - 4x = 12
