According to the presented question, m∢PSQ = 3y - 15 and m∢PRQ = 2y + 15, then m∢PSQ equals 97.

Supplementary angles are a pair of angles that always sum to 180 degrees. These two viewpoints are referred to as complements to one another. The English word "supplementary" is derived from the Latin words "Supplere" and "Plere," which respectively mean "supply" and "fill." As a result, the term "supplementary" designates something that is added to complete a task.

In this lesson, we will study about supplementary angles and how they can be applied to various geometry problems. As we explore supplementary angles, we'll discover how they differ from complimentary angles.

We know that the measure of an angle is supplementary to its adjacent angle. That means that the measure of an angle and its adjacent angle add up to 180 degrees.

Given that m∢PSQ = 3y - 15 and m∢PRQ = 2y + 15, we can set up the equation:

m∢PSQ + m∢PRQ = 180

Plug in the values for the angles:

(3y - 15) + (2y + 15) = 180

Simplifying, we get:

5y = 180

Now we can find the value of y by dividing both sides by 5:

y = 36

Therefore, m∢PSQ = 3y - 15 = 3(36) - 15 = 97

So, the measure of angle PSQ is 97 degrees.

The equation for the remaining work is given by the equation  25 - (x+y)

let x be the number of pizza made by Mario and y be the number of pizza made by luigi

let z be the pizza that still need to be made

so x+y+z=25

=> z = 25 - ( x + y )

so the total remaining pizza is given by 25 - (x+y) ---(i)

given that Mario had made 11 pizza so x = 11

The distance between two places cab be found using distance formula if you know the coordinates of the places.

The distance formula is a mathematical equation that can be used to find the distance between two points in a two-dimensional or three-dimensional space. The formula is as follows:

Distance = √((x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²)

Where x₁, y₁, and z₁ are the coordinates of the first point and x₂, y₂, and z₂ are the coordinates of the second point. The formula is based on the Pythagorean theorem, which states that the square of the distance between two points is equal to the sum of the squares of the differences in their coordinates.

For example, if you have the coordinates of two places on a map, you can use the distance formula to calculate the distance between them. Let's say the coordinates of place A are (x₁, y₁) = (4, 5) and the coordinates of place B are (x₂, y₂) = (9, 12). The distance between place A and place B would be:

Distance = √((x₂ - x₁)² + (y₂ - y₁)²)

= √((9 - 4)² + (12 - 5)²)

= √(5² + 7²)

= √(25 + 49)

= √(74)

To solve nth problems we use the formula stated as  aₙ = a + (n – 1)d.

A series in which the differences between each pair of following terms are the same is known as an arithmetic progression (AP). A formula for the nth term of the AP could be derived from this kind of progression. Because it follows a pattern where each number is acquired by adding 4 to the preceding term, the sequence 2, 6, 10, 14,... is an example of an arithmetic progression (AP). In this series, the nth term equals 4n-2. By changing the nth term to n=1,2,3,..., the sequence's terms can be obtained. i.e.,

First term when n = 1 is 4n-2 = 4. (1)

-2 = 4-2=2

second term = 4n-2 = 4 when n = 2 (2)

-2 = 8-2=6

The third term is 4n-2 = 4 for n = 3. (3)

-2 = 12-2=10

It takes a train going 50 mph approximately 11/2 miles to stop safely.

The distance a train takes to come to a stop can be determined by several factors, including the speed of the train, the weight of the train, the condition of the brakes and the track, and the reaction time of the engineer.

In general, a train going 50 mph will take about 1 1/2 miles or 8,000 feet to stop safely. This is because a train moving at 50 mph is traveling at about 75 feet per second, and it takes a significant distance to slow down a heavy object moving at such a high speed. It's important to note that this is an estimation, and the actual stopping distance may vary depending on the specific conditions.

The ratio of the sine of the angle of incidence to the sine of the angle of refraction is always a constant when the light is traveling from a denser medium to a rarer medium and the angle of incidence is greater than the critical angle.

The ratio of the sine of the angle of incidence to the sine of the angle of refraction is always a constant under the condition of total internal reflection.

This constant is known as the refractive index of the medium in which the light is traveling. When a beam of light passes from one medium to another, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is known as the refractive index of the second medium with respect to the first medium.

Total internal reflection occurs when a beam of light passes from a medium with a higher refractive index to a medium with a lower refractive index, and the angle of incidence exceeds the critical angle. Under this condition, the light is reflected back into the original medium, instead of passing into the second medium.

In short, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is always a constant when the light is traveling from a denser medium to a less dense medium and the angle of incidence is greater than the critical angle.

Using the area of square formula, we know that:

Area of square = side x side

Area of square = side²

Area of E = e x e

Area of E = e²

Area of F = f x f

Area of F = f²

We will compare the area of both squares:

Area of E = (1 + 44%)Area of F

e² = (1 + 44%) f²

e² = 1.44 f²

The pair of linear equations does not have a solution when K is equal to 2.

We can solve this system of linear equations by using the process of elimination. This involves rearranging the equations to isolate one variable and then using that information to determine the values of the other variables.

The first equation should be multiplied by (k-1) and the second equation by 3.

3(3x+y)=3

(2k-1)(3x + y)=(2k-1)2k+1

Add the two equations

3(3x+y)+(2k-1)(3x+y)=(2k-1)2k+1 + 3

Simplify the equation

5kx+ (3+2k-1)y = (2k-1)2k+1 + 3

Further simplify the equation

5kx + (2k+2)y = (2k-1)2k+1 + 3

Rearrange the equation

5kx - (2k+2)y = (2k-1)2k+1 + 3 - (2k+2)

Simplify the equation

5kx - (2k+2)y = (2k-1)2k+1 -2

With the LHS set to 0 and the RHS set to a non-zero number, we can determine the value of k for which the equations cannot be solved.

5kx - (2k+2)y = 0

(2k-1)2k+1 -2 ≠ 0

Solve for k

5k = 2k +2

3k = 2

k=2

Having two sets of parallel sides makes a quadrilateral a parallelogram. A parallelogram has opposite sides that are the same length and angles that are the same size. Additionally, the internal angles on the same transverse side are supplementary. 360 degrees are equal to the total of all internal angles.

In a parallelogram, opposite sides are congruent.

Answer:

To find the speed of the boat in still water, we can use the formula:

Speed in still water = (Downstream speed + Upstream speed) / 2

We know that the speed of the current is 1.5 km/h and the boat can travel twice the distance downstream as it can travel upstream. Therefore, if the boat travels x km downstream in one hour, it travels x/2 km upstream in one hour.

We can use this information to set up the following equation:

x + (x/2) = (x + x/2) = (3/2)x = Downstream speed

And the upstream speed is x/2

Now we can substitute this value into the formula for speed in still water:

Speed in still water = ( (3/2)x + (x/2) )/2 = (3x + x)/4 = x = (3+1) km/h = 4 km/h

So, the speed of the boat in stillwater is 4 km/h.

We don't know the exact distance that the boat travels downstream in one hour, so we can't calculate the speed in still water with the given information. To find the speed in still water we need to know the distance traveled downstream or upstream.

Principal, P = $ 300,000

Rate, R =  20%

Time, T = 30 years

The down payment would be 300,000 x 20% = $60,000.

The principal for the home loan after the down payment would be 300,000 - 60,000 = $240,000.

The total amount owed to the bank including principal and interest would be 240,000 + 232200 = $462200.

To calculate the monthly payment for a 30 year mortgage, you would use the formula:

(principal + interest) / (number of months in 30 years)

which would be ($462200) / (360 months) = $1283.33

To calculate the total monthly cost including another 300 per month for taxes and 150 per month for insurance, you would add the mortgage payment to the additional costs:
