What is a furry? If I draw fursonas am I a furry? I am seriously questioning my life rn. Plz help.
Don’t hate on furries plz
Answer:
iam sorry but furries are good lg!!!
Furry can have two definitions. A furry is either an anthrophomorphic animal which has human characteristics or a person that shows interest in furries. If you draw other people's fursona, i don't think that makes you a furry tbh. If you show interest and if you have your own fursona and you're passionate about it, however, then yeah you're pretty much a furry. Being a furry isn't bad honestly, it's just a hobby. I'm a furry myself and i honestly love this fandom. I met a lot of great people!

The senior classes at High School A and High School B planned separate trips to the water park. The senior class at High School A rented and filled 14 vans and 2 buses with 270 students. High School B rented and filled 9 vans and 9 buses with 459 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.
Answer:
x = number of students in the van = 14
y = number of students in the bus = 37
Step-by-step explanation:
Let
x = number of students in the van
y = number of students in the bus
14x + 2y = 270 (1)
9x + 9y = 459 (2)
Multiply (1) by 9 and (2) by 2
126x + 18y = 2,430 (3)
18x + 18y = 918 (4)
Subtract (4) from (3)
126x - 18x = 2,430 - 918
108x = 1,512
x = 1,512 / 108
= 14
x = 14 students in each van
Substitute x = 14 into (1)
14x + 2y = 270
14(14) + 2y = 270
196 + 2y = 270
2y = 270 - 196
2y = 74
y = 74/2
= 37
y = 37 students in each bus
x = number of students in the van = 14
y = number of students in the bus = 37

Write a linear equation in slope intercept form of a line with a slope of 12 and y intercept of 10
Answer:
y = 12x + 10
Step-by-step explanation:
The equation of the line in slope-intercept form is y = 12x + 10.
What is a slope?The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
The slope-intercept form of a linear equation is given by y = mx + b, where m is the slope and b is the y-intercept.
Given that the slope is 12 and the y-intercept is 10, we have:
y = 12x + 10
Therefore, the equation of the line in slope-intercept form is y = 12x + 10.

Can somebody please help me with this question!
Step-by-step explanation:
angle A = angle D
angle C common angle
angle E = 180 - 63 - 52
5x = 65
x = 13deg
Topic: congruence and similarity

Answer:
x = 13°
Step-by-step explanation:
Because of the given congruency,
Angle A = Angle D = 63°.
Angle C = 52°
Angle B = Angle E = 5x
Now, In Triangle ABC,
Angle A + Angle B + Angle C = 180°.
63° + 5x + 52° = 180°
115° + 5x = 180
5x = 65°
x = 13°

Congruent polygons are similar polygons for which the ratio of the corresponding sides is 1:1.
James's Dog, Buddy, is 2 years older than Fluffy, the neighbor's cat. Three Years ago, Buddy was three times older than fluffy. How old are the dog and cat now?
Answer: The cat is 4 years old, and the dog is 6 years old.
Step-by-step explanation:
We know that Buddy is 2 years old than Fluffy.
And 3 years ago, Buddy was 3 times older than Fluffy.
Let's define the variables:
B = age of Buddy
F = age of Fluffy.
The first statement can be written as:
B = F + 2
The second statement can be written as:
B - 3 = 3*(F - 3)
To solve this, we can replace the first equation into the second one, and solve that for F
B - 3 = 3*(F - 3)
(F + 2) - 3 = 3*F - 9
F - 1 = 3*F - 9
-1 + 9 = 3*F - F
8 = 2*F
8/2 = 4 = F
Fluffy is 4 years old, and with the first equation we can find the age of Buddy.
B = F + 2 = 4 + 2 = 6
Buddy is 6 years old
The required age of the dog buddy is 6 years old and the age of cat fluffy is 4 years old.
Given ,
James's dog buddy is 2 years older than Fluffy,
And the neighbor's cat Three Years ago, Buddy was three times older than fluffy.
Let ,
The age of buddy = B
The age of fluffy is = F
According to the question ,
Buddy, is 2 years older than Fluffy= Age of Buddy = Age of fluffy + 2 years older.
B = F +2
Again According to the question,
Three years ago age of Buddy = B - 3
Three years ago age of Fluffy = F - 3
Three years ago Buddy was three times older than fluffy = Three years ago age of Buddy = 3 × Three years ago Age of fluffy
B - 3 = 3 ( F - 3 )
Solving the equations,
B - 3 = 3 ( F - 3 )
Put the value of B from equation 1
F + 2 - 3 = 3 ( F -3 )
F - 1 = 3F - 9
F - 3F = - 9 +1
-2F = -8
2F = 8
[tex]F = \frac{8}{2}[/tex]
F = 4
The age of fluffy is 4 years old.
Then ,
The age of buddy
B = F + 2
B = 4 + 2
B = 6
The age of buddy is 6 years old.
The required age of the dog buddy is 6 years old and the age of cat fluffy is 4 years old.

Learning Task 4. Solve the problem by applying the sum and product of roots
of quadratic equations.
The perimeter of a rectangular metal plate is 36 dm and its area is 80
dm². Find its dimensions. (Relate the measures to the sum and product of a
quadratic equation.)
The perimeter of a rectangle is twice the sum of its length and width while
its area is the product of its length and width. Such that,
Perimeter = 2(L+w) and Area = L•w.
Answer:
Thus, the dimensions of the metal plate are 10 dm and 8 dm.
Step-by-step explanation:
For a quadratic equation:
[tex]x^2+bx+c=0[/tex]
The sum of the roots is -b and the product is c. Note the leading coefficient is 1.
We know the perimeter of the rectangular metal plate is 36 dm and its area is 80 dm^2. Being L and W its dimensions, then:
P=2(L+W)=36
A=L.W=80
Note both formulas are closely related to the roots of the quadratic equation, we only need to adjust the data for the perimeter to be exactly the sum of L+W and not double of it.
Thus we use the semi perimeter instead as P/2=L+W=18
The quadratic equation is, then:
[tex]x^2-18x+80=0[/tex]
Factoring by finding two numbers that add up to 18 and have a product of 80:
[tex](x-10)(x-8)=0[/tex]
The solutions to the equation are:
x=10, x=8
Thus, the dimensions of the metal plate are 10 dm and 8 dm.

Rahul has a farm he wishes to fence. The farm is the pentagon ABCDE, shown below. He knows that ABCD is a 140 m by 150 m rectangle, as shown below. He also knows that E is 50 m from the side AB and 30 m from the side BC. Determine the length of AE, the length of DE, and the perimeter of pentagon ABCDE
The diagram of the pentagon is missing, so i have attached it.
Answer:
|AE| = 130 m
|DE| = 150 m
Perimeter of pentagon = 720 m
Step-by-step explanation:
From the diagram, we can find AE from pythagoras theorem;
|AE| = √(|AA'|² + 50²)
Where AA' is the length from A to the perpendicular angle.
Now, AB = 150, and A'B is parallel to 30 m. Thus, A'B = 30
AA' = AB - A'B = 150 - 30
AA' = 120
Thus;
|AE| = √(120² + 50²)
|AE| = √(14400 + 2500)
|AE| = √16900
|AE| = 130
Similarly,
|DE| = √(|DD'|² + |ED'|²)
ED' = BC - 50
ED' = 140 - 50
ED' = 90
Also, DD' is parallel to AA' and is = 120
Thus;
|DE| = √(120² + 90²)
|DE| = √22500
|DE| = 150
Perimeter of pentagon = 150 + 130 + 150 + 150 + 140 = 720
