The sum of the interior angles of a regular polygon of 12 sides is 1800°
What is a polygon?A polygon is a planar figure characterized by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.
The sum of the all the interior angles of a polygon with 'n' number of sides is given by the formula,
Sum of all the angles = (n-2) × 180°
Since the number of sides in the polygon is 12, the sum of the angles will be,
Sum = (12-2) × 180° = 10 × 180° = 1800°
Hence, the sum of the interior angles of a regular polygon of 12 sides is 1800°.

The height of the oak tree is 2.5 meters. what is the height of the oak tree in
inches?
(1 ft. 0.305 m)
show your work!
Answer:
98.4 inches
Step-by-step explanation:
1 meter is about 3.28 ft, meaning the oak tree is 8.2ft tall. (2.5*3.28)
1 foot is 12 inches, meaning the oak tree is 98.4 in tall. (8.2*12)
The height of the oak tree = 98.42 inches.
Given that,
The height of the oak tree is 2.5 meters
We have to find height of tree in inches.
Since we know that,
A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.
Since we know that,
1 meter = 39.37
Then to find the height of oak tree in inches
Multiply 2.5 with 39.37
Therefore,
The height of the oak tree in inches = 2.5 x 39.37
= 98.42 inches

X+17=38 which property is included in the justification for the steps used to solve the equation?
Looking at the problem statement, the question is asking for us to determine the justification for the steps that are used to help solve the equation. We are given the expression [tex]x + 17 = 38[/tex] to help achieve that goal.
Now that we know what we must do to finish this problem let us look how this equation can be solved. When the term solve the equation is used it refers to us solving for the unknown, in this case being the variable x. We can see that we have [tex]x + 17[/tex] on the left side and in order to solve the equation x must be alone so we would subtract 17 from both sides.
Subtract 17 from both sides
[tex]x + 17 = 38[/tex][tex]x + (17 - 17) = (38 - 17)[/tex][tex]x = (38 - 17)[/tex][tex]x = 21[/tex]Therefore, we know that we must subtract the same number from both sides and this justification is known as the Subtraction Property of Equality. This basically states that an equal value needs to be subtracted from both sides and it will become a new equation but with the same result.
Answer:
Subtraction Property of Equality
Step-by-step explanation:
Given: x + 17 = 38
Algebraic Properties:
Addition: If a = b, then a + c = b + c
Subtraction: If a = b, then a - c = b - c
Multiplication: If a = b, then ac = bc
Division: If a = b, then a ÷ c = b ÷ c
To solve this equation, we know that we need to isolate the variable x. To do this, we need to subtract 17 from both sides to isolate x.
This is also known as the subtraction property of equality, which states that when the same thing is subtracted from both sides of an equation, the equation will still be balanced.
Subtract 17 from both sides:
x + 17 - 17 = 38 - 17
⟹ x = 21
Therefore, the subtraction property of equality is included in the steps used to solve this equation.

what three consecutive odd integers have a sum of 64. show steps please
There are no such integers. Odd + odd = even, and adding odd to that makes it odd again. But 64 is even.
Put another way, let n be the smallest of the three integers. Then
n + (n + 2) + (n + 4) = 64
3n + 8 = 64
3n = 56
But 3 does not divide 56, so there is no integer solution for n.

Factor the algebraic expression.
18a+15
Answer: 3(6a+5)
We can confirm this by distributing the 3 back in
3*6a = 18a
3*5 = 15
So 3(6a+5) = 3*6a+3*5 = 18a+15
The process of factoring polynomials like this is basically using the distributive property in reverse.
Answer:
3(6a + 5)
Step-by-step explanation:
1) Find the Greatest Common Factor (GCF).
1 - What is the largest number that divides evenly into 18a and 15?
It is 3.
2 - What is the highest degree of a that divides evenly into 18a and 15.
It is 1, since a s not in every term.
3 - Multiplying the results above,
The GCF is 3.
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3 (18a/3 + 15/3)
3) Simplify each term in parentheses.

doubling the sum of 5 and a number is equal to the same number decreased by 2. what is the equation
Answer:
2(x + 5) = x - 2
⟹ x = -12
Step-by-step explanation:
Doubling the sum of 5 and a number is equal to the same number decreased by 2. What is the equation?
This word problem can be written as:
⟹ 2(x + 5) = x - 2
1. Distribute:
2(x) + 2(5) = x - 2
⟹ 2x + 10 = x - 2
2. Subtract x from both sides:
2x - x + 10 = x - x - 2
⟹ x + 10 = -2
3. Subtract 10 from both sides:
x + 10 - 10 = -2 - 10
⟹ x = -12
4. Check your work:
2(x + 5) = x - 2
2(-12 + 5) = -12 - 2

Answer:
[tex]b = 9[/tex]
Step-by-step explanation:
[tex]\frac{2}{3} b + 5 = 20 - b[/tex]
In order to solve for b, we must isolate the variable. We can start by subtracting 5 from both sides.
[tex]\frac{2}{3} b + 5 - 5 = 20 - b - 5[/tex]
Simplify.
[tex]\frac{2}{3} b = 15 - b[/tex]
Add b to both sides.
[tex]\frac{2}{3} b + b = 15 - b + b[/tex]
Simplify.
[tex]\frac{2}{3} b + b = 15[/tex]
Multiply everything by 3 to remove the fractions.
[tex]3(\frac{2}{3}b+b) = 3(15)[/tex]
Simplify.
2b + 3b = 45

5b = 45
Divide 5 from both sides.

Find the function of (0,6), (3,15.8) and (9.5,0)
The polynomic function that contains the points (0, 6), (3, 15.8) and (9.5, 0) is a quadratic function, whose model is y = -0.600 · x² + 5.066 · x + 6.
How to derive a polynomic function from given points
To determine the coefficients of a polynomic function we must know a set of distinct points, whose number is the same number of coefficients. In this case, we can derive a quadratic function, as quadratic functions have three coefficients:
y = a · x² + b · x + c (1)
Now we substitute x and y in (1) and solve the resulting system of linear equations:
c = 6
9 · a + 3 · b + c = 15.8
90.25 · a + 9.5 · b + c = 0
Whose solution is a ≈ -0.600, b ≈ 5.066 and c = 6.

At a basketball game, 45% of people attending were supporting the home team, while 55% were supporting the visiting team. If 1413 people attending the game supported the home team, what was the total number of people attending the game?
divide the number of people supporting the home team by the percentage supporting the home team.
1413/0.45 = 3140
total people = 3,140
The total number of people attending the basketball game was 3140.
Let's denote the total number of people attending the game as "T."
According to the information given, 45% of the people were supporting the home team. Therefore, the number of people supporting the home team can be calculated as 45% of the total number of people: 0.45 * T.
We are also told that 1413 people supported the home team. So, we can write the equation:
0.45 * T = 1413
Now, let's solve for the total number of people attending the game (T):
T = 1413 / 0.45
T = 3140
Therefore, the total number of people attending the basketball game was 3140.

Write the equation of the line that passes through (4, 2) and is parallel to the line y = 2x – 1.
Answer:
Step-by-step explanation:
We will look for a line that has the general form of y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).
A line parallel to y=2x-1 will have the same slope, 2.
We can write y = 2x + b for the new line. We need to find b. We can use the given point in this equation and solve for b:
y = 2x + b
2 = 2(4) + b for (4,2)
2 = 8 + b
x = -6
The parallel line to y=2x-1 that goes through point (4,2) is:

while surfing the internet, she learned that the dealer's cost is
approximately 83% of the base price and 80% of the price of the options.
what should barrons estimate as the dealer's cost? (section 9-2) *
o a. $19,224.92
b. $17,659.09
c. $17,500.25
d. $19,430.84
Answer:
a. $19,224.92
Step-by-step explanation:
The dealer's cost will be the sum of the dealer's costs for the base car, its options, and the destination charge.
__
cost for base car = 0.83 × $21,276 = $17,659.08
cost for options = 0.80 × $1,219.80 = $975.84
cost for destination charge = $590.00
The sum of the dealer's costs is ...
$17,659.08 +975.84 +590.00 = $19,224.92
Barrons should estimate the dealer's cost to be $19,224.92.
