Find the sum of the interior angles of a regular 14-gon.
9514 1404 393
Answer:
2160°
Step-by-step explanation:
The sum of interior angles of a convex n-gon is ...
angle sum = 180(n -2)°
When n=14, the angle sum is ...
angle sum = 180(14 -2)° = 2160°
n-6=2n-n
pls help solve :)
Answer:eorder the terms:
-6 + n = 2n + -1n
Combine like terms: 2n + -1n = 1n
-6 + n = 1n
Solving
-6 + n = 1n
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-1n' to each side of the equation.
-6 + n + -1n = 1n + -1n
Combine like terms: n + -1n = 0
-6 + 0 = 1n + -1n
-6 = 1n + -1n
Combine like terms: 1n + -1n = 0
-6 = 0
Add '6' to each side of the equation.
-6 + 6 = 0 + 6
Combine like terms: -6 + 6 = 0
0 = 0 + 6
Combine like terms: 0 + 6 = 6
0 = 6
Simplifying
0 = 6
Combine like terms: 0 + -6 = -6
-6 = 6 + -6
Combine like terms: 6 + -6 = 0
-6 = 0
Step-by-step explanation:
Answer:
-6 = 0n
Step-by-step explanation:
n - 6 = 2n - n
n - 6 = n
-n -n
-6 = 0n

which of the following is NOT a characteristic of a parallelogram
Answer:
If all the points do not connect then you do not have a parallelogram. If all of the sides are not of equal length, them being parallel than this is not a parallelogram. Opposite edges and angles have to be congruent for it to be a parallelogram.
Step-by-step explanation:
A rectangular prism has a base that is
congruent to the base of a rectangular
pyramid. The heights, h, of the two figures
are also congruent. If the volume of the
pyramid is 100 inches, which expression can
be used to find the volume of the prism?

Which of the following equations is true to find the length BC?
Answer:
BC/sin 23 = 10/sin 47
Step-by-step explanation:
Here, we want to select the true equation to find the length BC
From the question, we have the angle facing side BC; also, we have the angle and the side facing it for another side
In this situation, the best way to solve for BC is by the use of the sine rule
The sine rule states that the ratio of the length of a side and the sine of the angle facing the side is constant for a given triangle
Thus, we have it that;
BC/sin 23 = 10/sin 47

A university has three table tennis scholarships each worth $1000. How many ways are there to award these after they've narrowed
the candidates to 6 ping pong players?
Blank 1:
Answer:
1. In the presence of restrictions; A player cannot win more than one scholarship;
The number of ways is 120 ways
2. In the absence of restrictions; A player can win more than 1:
The number of ways is 216 ways
Step-by-step explanation:
Here, to award the scholarships, the restrictions we might have is that a student cannot win more than 1 scholarship
Given this restriction;
The first scholarship has 6 possible contenders
The second has 5
The third has 4
So, the number of possible ways is;
6 * 5 * 4 = 120 ways
In the absence of no restrictions where a student can win any number of scholarships;
We have the 3 scholarships being awarded in 6 possible ways
So the total number of ways will be;
6 * 6 * 6 = 216 ways

If 1432x-3 = 143x+1, then...
Answer: x= 4/1289 not sure if this was what you were looking for.
Step-by-step explanation:
Step 1: Subtract 143x from both sides.
1432x−3−143x=143x+1−143x
1289x−3=1
Step 2: Add 3 to both sides.
1289x−3+3=1+3
1289x=4
Step 3: Divide both sides by 1289.
1289x/1289 = 4/1289
x= 4/1289
