The Scale factor was used to enlarge the picture is 7/ 31.5.

A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is used to find the missing length, area, or volume of an enlarged or reduced figure as well as to draw the enlarged or reduced shape of any given figure. It should be remembered that the scale factor only affects how big a figure is, not how it looks.

Given:

A picture is 7 inches wide and 9 inches long.

A photographer enlarges it so it is 31.5 inches wide and 40.5 inches long.

So, scale factor is

= Original dimension / Enlarged dimension

= 9/ 40.5

= 90/ 405

= 10/45

= 2/9

Now, simplifying the scale factor 7/31.5 because it has Nr < Dr.

= 7/ 3.15

= 70/31.5

= 2/9

Latitude is always presented before longitude when giving a coordinate. Degrees, minutes, and seconds are used to divide latitude and longitude. While a degree is made up of 60 minutes, a minute is made up of 60 seconds.

Latitude lines run parallel with each other from east to west. The more north you travel, the higher the latitude values. Last but not least, latitude values vary from -90 to +90. However, longitude lines run from north to south. Latitudes are lines that are horizontal and indicate how far away from the equator a location is.

The average ticket price for the concert, expressed in dollars, is given by the equation P = (TP + PR)/(T + ).

The average ticket price, P, in dollars, of all tickets sold to the concert is represented by the equation P = (T + ηR)/(T + η) where T is the original ticket price, R is the price increase, η is the number of tickets sold on the day of the concert, and T + η is the total number of tickets sold to the concert.

In this scenario, before the concert, the theater sells T tickets at a price of P dollars each, and on the day of the concert, the theater increases the ticket price by R dollars and sells η tickets.

Therefore, the average ticket price for all the tickets sold is the sum of the original ticket price and the increased ticket price, divided by the total number of tickets sold.

P = (TP + η(P+R))/(T + η)

P = (TP + ηPR)/(T + η)

So, the equation P = (TP + ηPR)/(T + η) represents the average ticket price, in dollars, of all tickets sold to the concert.

Answer:

∠ PQS = 15°

Step-by-step explanation:

PQRS is a cyclic quadrilateral

• the opposite angles of a cyclic quadrilateral sum to 180° , then

∠ QPS + ∠ QRS = 180°

∠ QPS + 105° = 180° ( subtract 105° from both sides )

∠ QPS = 75°

the sum of the 3 angles in Δ PQS = 180° , that is

∠ PQS + ∠ PSQ + ∠ QPS = 180°

∠ PQS + 90° + 75° = 180°

∠ PQS + 165° = 180° ( subtract 165° from both sides )

And here we need to find the vertex for the function that can be calculated as,

As we all know that vertex form of a parabola is written as,

=> y = a (x - h)² + k

Here we know that (h, k) is the vertex

Then the given expression is written as,

=> g(x) = -3x²  + 18x + 2

When we can be written by completing the square as follows,

=> y = -3x²  + 18x + 2

Here we have to take 3 as common term, then we get

=> -3(x²  + 6x)+ 2

now, we have to expand the expression within the brackets, then we get,

The area of the triangle xyz is 33.941...

To calculate area of triangle, we need to take the base and height's measurement.

Formula- 1/2 x Base x Height

However, Area may also be calculated when we know the 3 sides of the triangle.

It is known as "Heron's Formula"

Simply use this 2 step process :

Step 1-

Calculate "S" (which is half of the triangle's perimeter)

S = (side1 + side2 + side3) / 2

Naming the sides as a b and c respectively.

4 inches = a

5 inches = b

7 inches = c

 S = ( a + b + c ) / 2

S = ( 4 + 5 + 7 ) / 2

S = 16/2

S = 8

Step 2: Calculating the area of the triangle XYZ

Formula:

Area ( A ) = √S(S−a)(S−b)(S−c)

put the values and you will get the answer.

A = √8(8−4)(8−5)(8−7)

A = 33.941..

If the height is 4 and base is 5 ( or the opposite)

Area= (4.5)/2

OM is probably perpendicular to CD and EF is perpendicular to ON, and I'm assuming there's more information there.
