The expression for pressure is P = k/V and pressure is 50 pounds per square inch.

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.

Given pressure and volume are inversely proportional to each other

P ∝ 1/V

P = k/V

given when pressure p = 25 pounds per square inch

then volume V = 400 cubic inches

25 = k/400

k = 10,000

and when  V = 200 cubic inches

then P = k/V

P = 10000/200

P = 50 pounds per square inch

Hence pressure is 50 pounds per square inch.

Answer:

5^2 would be 5*5 =25 so 5^2 is 25

Step-by-step explanation:

Answer: In order to solve this problem, you should use the Pythagorean theorem. Since FG is perpendicular to OP, and OP and OQ are radii of the same circle, then triangle OFG is a right triangle. Similarly, triangle ORS is also a right triangle. By using the Pythagorean theorem, you can find that:

OF = sqrt(OP^2 + FG^2) = sqrt(19^2 + 40^2) = sqrt(361 + 1600) = sqrt(1961)

and

OS = sqrt(OQ^2 + RS^2) = sqrt(19^2 + 37^2) = sqrt(361 + 1369) = sqrt(1740)

Therefore, the length of the segment connecting the feet of the altitudes is:

OF + OS = sqrt(1961) + sqrt(1740) = 27.2

So the answer is A. 27.2

On solving the provided question, we can say that The perimeter of the Isosceles  triangle is 8 + 4v'5+ 4[tex]\sqrt{2}[/tex]= 8 + 8[tex]\sqrt{2}[/tex] = +[tex]\sqrt{2}[/tex])

A triangle with two sides that have the same length is said to be isosceles. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.

A right triangle's three sides are related in Euclidean geometry by the Pythagorean theorem, also known as Pythagoras' theorem. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The hypotenuse is 8 so the equal sides are x lets say.

Now, by Pythagoras Theorem

x^2 + x^2 + = 8^2

x^2 = 64/2

x = [tex]4\sqrt{2}[/tex]

The perimeter of the triangle is 8 + 4v'5+ 4[tex]\sqrt{2}[/tex]= 8 + 8[tex]\sqrt{2}[/tex] = +[tex]\sqrt{2}[/tex])

Residual Value should not be more than 5% of Cost of Asset i.e Rs. 5000 and accordingly the amount to be adjusted shall be Rs.

What Exactly Is Residual Value?

The estimated value of an asset that is fixed at the end of its useful life or lease term is its residual value, which is often referred to as salvage value. In lease agreements, the residual value is one of the lessor's main methodologies for calculating the lessee's periodic lease payments.

A good residual value is what?

Check out the Car Lease Ratings section of our Lease Kit for a complete list of high-residual vehicle brands and models.

                 A car is probably not a good lease deal if the lease-end residual value is less than 50% of the MSRP (for a 36-month lease). 55% to 65% of MSRP would be a nice residual.

The concept given is Sampling, which selects the group that you will actually collect data from in your research. The answer is option B, ​True; because it is often the case that the individuals who volunteer do not accurately represent the population.

Sampling is the selection of a subset of individualities from within a statistical population to estimate the characteristics of the whole population. Statisticians essay to collect samples that are representative of the population in question.

Frequently, voluntary response samples oversample people who have strong opinions and under-sample people who do not watch important about the content of the check. Therefore consequences from a voluntary response sample aren't as secure as conclusions grounded on an arbitrary sample of the entire population under consideration.

Volunteer slice doesn't induce a representative sample, so, thus, would not be the favored choice of experimenters who were keen to be suitable to generalize their data to the whole population.

You buy 3 tickets. You spent $225 to buy the tickets.

What is an equation?

A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.

Given that there are two planes to buy tickets.

First plane offers $75 per ticket.

The other plan offers $180 plus $15 per ticket.

Assume that you buy x number of tickets.

According to the first plane, the total cost of x number of tickets is y = $75x.

According to the second plane, the total cost of x number of tickets is y = $180 + 15x

The system of equations is

y = $75x .....(i)

y = $180 + 15x  ....(ii)

Using the substitution method solve the equations.

The solution of the equations represents the total cost for the two options is the same.

Putting y = 75x in equation (ii)

75x = 180 + 15x

Subtract 15x from both sides:

75x - 15x = 180

60x = 180

Divide both sides by 60:

x = 3

Putting x = 3 in equation (i)

y = 75 × 3

y = 225

Guidelines are presented on how to both graphically and mathematically solve for the equation.  

Graphing:  Mark the the two given points and connect them with a ruler to form the line.  These same two points may be used to determine the slope, as is shown.  The slope is 2.  The line intersects the y axis at 3, so the y-intercept is 3.  Using the standard form of an equation, the line is y = 2x + 3, as is outlined in the attachment.

The same line is determined mathematically by using the same technique for calculating slope.  The value of the y-intercept may be found by using one of the two given points in the equation that has the slope of 2:

  y= 2x +b

Enter pont (-1,1), for example, and calculate the value of b. b = 3, (since 1 = 2*(-1)+ b, so b=3).

If the two rates​ continue, the number of hours when the prices of the two stocks would be the​ same is equal to 1.85 hours.

In order to write a system of algebraic equation to describe this situation, we would assign variables to the price of Stock A and the price of Stock B after a certain number of hours respectively, and then translate the word problem into algebraic equation as follows:

For the price of Stock A increasing at the rate of ​$0.11 each hour, an algebraic equation which models it is given by:

T = 12.81 + 0.11x

For the price of Stock A decreasing at the rate of ​$0.16 each hour, an algebraic equation which models it is given by:

T = 13.31 - 0.16x

Equating the two algebraic equations, we have:

12.81 + 0.11x = 13.31 - 0.16x

0.11x + 0.16x = 13.31 - 12.81

The coefficient of thermal expansion is defined as the fractional change in volume per unit change in temperature. It is calculated by taking the derivative of volume with respect to temperature. Mathematically, it is expressed as β = (1/V) (dV/dT). As the temperature approaches zero, the change in volume (dV) will also approach zero, and thus the coefficient of thermal expansion (β) will approach zero as well.

The area of the triangle is 54 square cm.

To find the area of a triangle, we can use Heron's Formula, which states that the area of a triangle is equal to the √ (s * (s-a) * (s-b) * (s-c)), where s is the semi-perimeter of the triangle and a, b, and c are the sides of the triangle.

Step 1: Find the semi-perimeter of the triangle. s = (9 + 12 + 15) / 2 = 21 / 2 = 10.5

Step 2: Substitute the semi-perimeter and the sides of the triangle into Heron's Formula.

Area =  √(10.5 × (10.5 - 9) × (10.5 - 12) × (10.5 - 15))

Step 3: Simplify the equation.

Area = √ (10.5 × 1.5 × -1.5 × -4.5)
