Step-by-step explanation:
A 1x1 square and an n-tiling is a group of n tiles placed so that every tile is contiguous along at least one side to another tile. (The tiles cannot be offset. That is, they must be placed into a grid like Scrabble tiles.) The edge length of a tiling is the total length of edges that are not touching other tiles. For instance, a 20-tiling, the edge length is 36.
Required:
Prove that for all n-tilings where n >= 1, the edge length is even.
Answer:
Step-by-step explanation:
The first picture below shows the missing image in the question.
There are 4 edges of each tile;
This clearly explains to us that the total number of edges present in the n tiles is 4n.
Now, if a tile "X" touches and comes in contact with another tile "Y", then edges touching each other are one edge of a tile X and one edge of a tile Y.
From the second diagram below, the edge, X_2, and Y_4 are touching each other.
Now, the total number of edges that touch some edges is always even.
We can now say that:
The edge length of filling = No. of edges that do not touch another file
= Total no. of edges - No. of edges that touch another edge.
However, the total number of edges is even.
The number of edges that touch another edge is also even.
Thus, the difference is also even and the number of edges that do not touch another is even.
So, the edge length of filling is always even.
Please help me please !
Answer:
For the first one:
y = 2/3x + 1
For the second one:
y = -5x + 4
Step-by-step explanation:
As you may already know, in the y=mx+b equation format:
m = slope
b = y-intercept
On the graph, it already shows the y-intercept, so you can automatically find your b in the equation.
And, the easiest, most quick way to find the slope by using a graph is to calculate using rise/run. So, by doing that you can calculate the equation.
Then, you can just leave the variables y and x alone.
Hope this helped!!

What is the distance between points A and B shown in the graph below
Answer:
[tex]D = 7\sqrt 2[/tex]
Step-by-step explanation:
Given
[tex]A = (-3,-4)[/tex]
[tex]B = (4,3)[/tex]
Required
The distance between them
This is calculated as:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
So, we have:
[tex]D = \sqrt{(3-(-4))^2+(4-(-3))^2}[/tex]
[tex]D = \sqrt{7^2+7^2}[/tex]
[tex]D = \sqrt{2(7^2)}[/tex]
[tex]D = 7\sqrt 2[/tex]

A beach resort has 29 jet skis for guests to rent. Of these, 14 are two-person skis, 18 haveturbo packs, and 10 are both for two persons and have turbo packs. LetTbe the event that a jetski, randomly chosen, is a two-person ski, and letPbe the event that the ski has a turbo pack.A jet ski is chosen at random for rental. Find the probability for each of the following events.
Questions:
a. The jet ski is for two persons and has turbo packs.
b. The jet ski is not for two persons but has turbo packs.
Answer:
[tex]P(P\ and\ T) = \frac{10}{29}[/tex]
[tex]P(P\ and\ T') = \frac{270}{841}[/tex]
Step-by-step explanation:
Given
[tex]n=29[/tex] --- Total
[tex]T = 14[/tex] --- Two person skis
[tex]P = 18[/tex] --- Turbo packs skis
[tex]P\ and\ T = 10[/tex] --- Two person ski and Turbo packs
Solving (a):
This is represented as: [tex]P(P\ and\ T)[/tex]
This is calculated as:
[tex]P(P\ and\ T) = \frac{n(P\ and\ T)}{n}[/tex]
[tex]P(P\ and\ T) = \frac{10}{29}[/tex]
Solving (a):
This is represented as: [tex]P(P\ and\ T')[/tex]
This is calculated as:
[tex]P(P\ and\ T') = P(P)\ and\ P(T')[/tex]
[tex]P(P\ and\ T') = P(P)\ *\ P(T')[/tex]
Using the complement rule, we have:
[tex]P(T') = 1 - P(T)[/tex]
The equation becomes:
[tex]P(P\ and\ T') = P(P)\ *\ [1 - P(T)][/tex]
[tex]P(P\ and\ T') = \frac{n(P)}{n}\ *\ [1 - \frac{n(T)}{n}][/tex]
[tex]P(P\ and\ T') = \frac{18}{29}\ *\ [1 - \frac{14}{29}][/tex]
[tex]P(P\ and\ T') = \frac{18}{29}\ *\ \frac{29-14}{29}[/tex]
[tex]P(P\ and\ T') = \frac{18}{29}\ *\ \frac{15}{29}[/tex]
[tex]P(P\ and\ T') = \frac{18*15}{29*29}[/tex]
[tex]P(P\ and\ T') = \frac{270}{841}[/tex]

Find the area of the following
triangle:
4.2 cm
3 cm
10 cm
A= [?] cm
Answer:
15 cm
Step-by-step explanation:
Base x height / 2 = Area(of a triangle) =
3 x 10 / 2 =
15 cm
The solution is : the area of the following triangle is, 15 cm².
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
Here, we have,
given that,
4.2 cm
3 cm
10 cm
We know that,
area = bh/2
i.e. we get,
Base x height / 2
= Area(of a triangle)
substituting the values, we get,
= 3 x 10 / 2
= 15 cm²
Hence, The solution is : the area of the following triangle is, 15 cm².

What is the area of the polygon shown below?
Answer:
66
Step-by-step explanation:
first you find the area of the rectangle
5*12=60
then you find the area of the triangle
to find the length of the dotted line you need to subtract 9 from 12 which is 3
to find the length of the line adjacent to the dotted line you need to subtract 5 from 9 which is 4
use the triangle area formula 3*4*1/2=6
add the areas of the triangle and the rectangle 60+6=66

A crowd-funding project has received $16,770, which is $1230 less than 90% of the goal amount. What is the goal amount?
Answer:
The goal is $19,800.
Step-by-step explanation:
$16,770 is $1,230 less than %90 of the goal. If you add 16,770 and 1,230, you get 18,000. Then you have to multiply that by 1.10 to get it to the goal. That is how you get $19,800, which is the answer.
need help solving -7=6+ k
---------- 10
Answer:
The answer is k = -13.
Step-by-step explanation:
1) Subtract 6 from both sides.
[tex] - 7 - 6 = k[/tex]
2) Simplify -7-6 to -13.
[tex] - 13 = k[/tex]
3) Switch sides.
[tex]k = - 13[/tex]
Therefor, the answer would be k = -13.
