Yes , Triangles are all tessellated. The triangle's three corners (A, B, and C) meet together to form a 180° angle, or a straight line, which is why the image is successful.
Is a triangle capable of tessellation?
Triangles are all tessellated. The triangle's three corners (A, B, and C) meet together to form a 180° angle, or a straight line, which is why the image is successful. We state it here since it will serve as the cornerstone of our investigation into polygon tessellations: Any triangle's total angles come to 180 degrees.To create a regular tessellation, it is necessary that the tiles may fill 360 degrees around a point (all the tiles regular polygons with same number of sides) Only 60 degree angle triangles, 90 degree squares, and 120 degree hexagons will work.
Every vertex, edge, and tile in a regular tesselation are identical.
However, there are semiregular tesselations that use more than one regular polygon, but since they must be able to fill 360 degrees around a point, it turns out that only the octagon (8 sides, 135 degrees) and dodecagon can be used as additional polygons (12sides, 150 deg).
Note that just these 5 tesselations can be utilized to fill the plane entirely with regular polygons.
Each vertex in the semiregular tessellations is the same.
Eight of them are (3,3,3,3,6), (3,3,3,4,4), (3,4,6,4), (3,6,3,6), (3,12,12), and (4,6,12). (4,8,8)

The line which have a steeper slope is Line 1.
It is given in the question that the points on the line are given by:-
Line 1: (-9,-4) and (7,0)
Line 2:(0,1) and (7,4)
We have to find which line has a steeper slope.
First we will find the slope of each line.
We know that slope of a line with points (a,b) and (c,d) is given by:-

Slope of Line 1:
(0-(-4))/(7-9) = 4/(-2) = -2 (we will take the absolute value)
Slope of Line 2:
(4-1)/(7-0) = 3/7

Use the given information to write an equation of the circle.
center (2,1) , through (6,4)
Using the given information, the equation of the circle with center located at point (2 , 1) and passes through the point (6 , 4) is (x - 2)^2 + (y - 1)^2 = 25
Using the distance formula, get the radius of the circle by solving for the distance between the center (2 , 1) and the point (6 , 4).
radius = distance = √(x2 - x1)^2 + (y2 - y1)^2
radius = √(6 - 2)^2 + (4 - 1)^2
radius= √16 + 9
radius = √25
radius = 5
The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.
(x - h)^2 + (y - k)^2 = r^2
where (h , k) = (2 , 1)
r = 5
(x - 2)^2 + (y - 1)^2 = 5^2

You are canning 40 cups of applesauce. You have 20 glass jars, each of which will hold 1 3/4 cups of applesauce. why do i not have enough jars
pls help
The jars are nor enough because the applesauce is more than 35 cups which is what 20 glass jars can contain. Since each of the cup will hold 1 3/4 cups of applesauce.
How to find why the jars are not enoughGiven data
number of cups of apple sauce = 40
number of glass jars = 20
number of cups each glass jar can hold = 1 3/4
solution
if one glass jar hold 1 3/4 cups then 20 glass jars will hold
= 20 * 1 3/4
= 35 cups
Since there are 40 available cups of apple sauce and the 20 glass jars is equivalent to 35 cups, hence the glass jars will contain 35 cups and there will be 5 cups left.

How to find the first five terms of sequence a₁ = -2, a (n) =a (n-1)-5 ?A recursive formula is one that defines each term in a sequence by reference to the one before it. The following parameters are defined using the recursive formulas:
1. The initial term in the series.
2. The general rule for determining any term from its preceding term.
Recursive Arithmetic Sequence Formula
The following is the recursive formula to determine the nth term in an arithmetic series:
an = an-1 + d for n ≥ 2
where
The common difference is d, and an is the nth term of an A.P.
given that
a₁ = -2
a (n) =a (n-1) -5 so, d = -5
For example, we need to extend the sequence term by term in order to find the first five terms:
a(1) = -2
a(2) = a(1) + d = -2 + (-5) = -7
a(3) = a(2) + d = -7 + (-5) = -12
a(4) = a(3) + d = -12 + (-5) = -17
a(5) = a(4) + d = -17 + (-5) = -22
a(6) = a(5) + d = -22 + (-5) = -27
Hence,this is recursive sequence and -2, -7, -12, -17, -22, -37 these are the first five terms of sequence.

Prove or disprove that the product of a nonzero rational number and an irrational number is irrational.
Answer: The claim is true
The proof is below
=====================================================
A = some nonzero rational number
B = some irrational number
Because value A is rational, this means A = p/q where p,q are nonzero integers.
Let's do a proof by contradiction. The claim is that A*B is irrational, but let's do the opposite and assume A*B is rational. We should get to a contradiction somewhere based on this assumption.
If A*B is rational, then A*B = r/s for some integers r and s
Then we can have the following steps
A*B = r/s
(p/q)*B = r/s
B = (r/s)*(q/p)
B = (rq)/(sp)
B = (some integer)/(some other nonzero integer)
B = some rational number
Recall we made B irrational. There's no way to have B rational and irrational at the same time. This is where the contradiction happens. This causes the original assumption of "A*B is rational" to be false. Therefore, the opposite must be the case and A*B has been proven to be irrational.
Therefore, the product of a rational number and an irrational number is irrational.

Example:
5 is rational
sqrt(3) is irrational

write this as an equation
Answer:
Step-by-step explanation:
Givens
Flight speed there = 12 feet / second
Flight speed back = 8 feet / second
Total time = 22 minutes
Time at rest = 18 minutes
Time in flight = 22 - 18 = 4 minutes

D. 9/π
The probability that a randomly chosen point in the interior of the square will also lie in the interior of the circle is π/9 .
Probability of an event is defined as the Number of favorable outcomes divided by total number of outcomes.
It is denoted by P(E).
Given that
radius of circle = 3
side of the square = 9
Let E be the event that a randomly chosen point in the interior of the square will also lie in the interior of the circle
then
[tex]P(E)=\frac{AreaOfCircle}{AreaOfSquare}[/tex] ...(i)
Area of Circle = πr² = π(3)² = 9π
Area of Square = (side)²=(9)²=81

What is sequence?An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.
Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.
An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.
