Answer:
150
Step-by-step explanation:
The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides. The problem concerns a polygon with twelve sides, so we will let n = 12. The sum of the interior angles in this polygon would be 180(12 – 2) = 180(10) = 1800.

What is the slope of the line that contains these points?
The slope of the line that contains the the given points is 1/5 .
The slope of the line containing the two points (x₁ , y₁) and (x₂ , y₂) is calculated using the formula
slope = (y₂ - y₁)/(x₂ - x₁)
In the question ,
it is given that the
line contains the points x [tex]=[/tex] -4 , y [tex]=[/tex] -3
and x = 1 , y = -2 .
we need two points to find the slope of the line
Substituting the values in the formula for slope ,
we get
slope = (-2 -(-3))/(1-(-4))
= (-2+3)/(1+4)
= 1/5
Therefore , The slope of the line that contains the the given points is 1/5 .

The number of way in which bride can rank the three Djs out of 6 is 120.
Defined the word permutation?The number of possible arrangements for a given set is determined mathematically, and so this procedure is referred to as permutation. Simply said, a permutation is a concept that refers to the wide range of possible arrangements or orders. The arrangement's order is important if using permutations.There are several different ways we might rank the three DJs.
Therefore, we must identify the permutation P. (6,3).
Total number of DJs = 6Required number of DJs = 3ⁿPₓ = n!/(n - x)!
⁶P₃ = 6!(6-3)!
⁶P₃ = 6×5×4
⁶P₃ = 120
Thus, the number of way in which bride can select the three Djs out of 6 is 120.

The final velocity of a vehicle with a mass of 800kg is 20000 m/s.
What is velocity?The primary indicator of an object's position and speed is its velocity. It is the distance that an object travels in one unit of time. The displacement of the item in one unit of time is the definition of velocity.The speed at which an object goes in one direction is known as its velocity. Speed may be used to calculate both the speed of the car traveling north on the major highway and the speed of the rocket bursting into space.So, calculate the final velocity as:
Formula: v = √u² + 2asWhere u is initial velocity, a is acceleration and s is displacement.Now, we know that:
u = 108 km/ha = 4 km/s²s = 50 kmInsert values in the formula and calculate as follows:
v = √u² + 2asv = √108² + 2(4)(50)v = √11,664 + 400v = √12,064v = 20000.022499991 m/sRounding off: v = 20000 m/s
Therefore, the final velocity of a vehicle with a mass of 800kg is 20000 m/s.

The expression is: V(x) = 4x³ - 22x² + 30x.The degree is of 3, the number of terms is of 3, and the leading coefficient is of 4.How to obtain the volume of a rectangular prism?The volume of a rectangular prism is given by the multiplication of the dimensions of the prism, which are the width symbolized by w, the height symbolized by h and the length symbolized by l, that is:
V = l x w x h.
In the context of this problem, from the image, the dimensions are given as follows:
Length: l = 2x - 5.Width: w = x - 3.Height: h = 2x.Then the polynomial expression regarding the volume of the prism is obtained as follows:
V(x) = 2x(x - 3)(2x - 5)
V(x)= 2x(2x² - 11x + 15)
V(x) = 4x³ - 22x² + 30x.

Step-by-step explanation:
- 3x - 6y = 45 → (1)
- 5y = x → (2)
substitute x = - 5y into (1)
- 3(- 5y) - 6y = 45
15y - 6y = 45
9y = 45 ( divide both sides by 9 )
y = 5
substitute y = 5 into (2)
- 5(5) = x , then
x = - 25

What is linear equation ?Linear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e. only one variable), then it is known as a linear equation in one variable. A linear equation can have more than one variable. If the linear equation has two variables, then it is called linear equations in two variables and so on. Some of the examples of linear equations are 2x – 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x – y + z = 3.
CalculationCost: C=72+6s, where s is the number of shirts sold

CARPENTRY A carpenter is building a podium. The side panel of the podium is cut from a rectangular piece of wood. The rectangle must be
sawed along the dashed line in the figure.
The measure of angle1 in the given rectangular figure is 64° .
In the question ,
it is given that ,
the one of the angle is 116° .
From the figure below ,
we can see that
the dashed line is a transversal to AB and CD ,
the angles on the line AB form a linear pair ,
So , angle2 + 116° = 180°
angle2 = 180° - 116°
angle2 = 64°
Since the side panel of the podium is cut from rectangular piece
the figure is representing two parallel lines , cut by the transversal .
By the property of transversal that alternate interior angles are equal in measure ,
angle 1 = angle 2
hence , angle 1 = 64° .
