Question Says:-An equilateral triangle is a triangle with three equal sides. The perimeter of an equilateral triangle varies directly with the length of one side. What is an equation that relates the perimeter p and length of a side?
Answer:-See, let us consider the sides as l as per question.
And, perimeter as p as per question.
We know that:-
The sum of all the boundary gives us the perimeter of the figure.
It is Equilateral Triangle, so the equation will be:-
[tex]l + l + l = p[/tex]
Now, adding it up, we get
[tex]3l = p[/tex]
So, 3l=p relates the side and perimeter.
Hope it helps :)

A motorized float in a Thanksgiving Day parade is traveling north at a speed of 16.0 km/h. Part of a "Pilgrim" woman's role in the thematic vignette is to walk across the float to call the men to dinner. She walks at a speed of 3.22 km/h east as the float passes the judge's booth, which is on the west side of the street. What is the woman's velocity with respect to the judge?
Answers
Answer:
16.32 N11.38°E km/h
Step-by-step explanation:
16.0∠0° +3.22∠90° ⇒ (x, y) = (3.22, 16.0) ⇒ (r, θ) =
(3.22, 16.0) ⇒ (r, θ) = (√(3.22² +16²), arctan(3.22/16)*) = (16.32, 11.38°)
The woman's velocity is 16.32 km/h in a direction that is 11.38° east of north.

How many toy trains does Jane make?
toy trains
Answers
Answer:
Here's how to solve it.
Step-by-step explanation:
Okay,
from what I understand she has 20 train cars total.
She uses 5 for each train.
So to solve you use simple division.
20 / 5 = 4
To check your answer substitute 4 in the equation so 4 × 5 does equal 20.
So it would be 4.

Teresa purchased a prepaid phone card for $15 . Long distance calls cost 24 cents a minute using this card. Teresa used her card only once to make a long distance call. If the remaining credit on her card is $3.96 , how many minutes did her call last?
Answers
Answer:
46 minutes
Step-by-step explanation:
Teresa purchased a prepaid phone for $15
Long distance calls cost 24 cents a minute using this card
She used the card just once to make a long distance call
The remaining credit on her card was $3.96
Therefore the minutes in which her call lasted can be calculated as follows
Let x represent the minutes
15 - 24/100x= 3.96
15-0.24x= 3.96
-0.24x= 3.96-15
-0.24x= -11.04
x= 11.04/0.24
x = 46
Hence Teresa call lasted for 46 minutes

Answer:
-1
Step-by-step explanation:
2y+6=1 -3y
add three to both sides and minus 6 from both sides becasue you want to get y by itself
5y=-5
now both sides by 5
y=-1
Answer:
y=−1
Step-by-step explanation:
2y+6=1−3y
Step 1: Simplify both sides of the equation.
2y+6=1−3y
2y+6=1+−3y
2y+6=−3y+1
Step 2: Add 3y to both sides.
2y+6+3y=−3y+1+3y
5y+6=1
Step 3: Subtract 6 from both sides.
5y+6−6=1−6
5y=−5
Step 4: Divide both sides by 5.
y=−1

a triangle has the following two angle measures:
based on the angles given the third angle must have a measure of _______?
Answers
Answer:
62°
Step-by-step explanation:
Given that the triangle has two angle measures of 41° and 77°.
All the angles in a triangle must add up to 180° (e.g. 20° + 60° + 100°). So we write a simple equation to solve for the mystery angle measure:
Let x = the missing measure
[tex]41 + 77 + x = 180[/tex]
Now that we have our equation, let's start solving it. First, we need to add 41 and 77 together which simplifies the equation: [tex]118 + x = 180[/tex]
Then we subtract 118 from both sides to isolate x - this will give us the value of this variable: [tex]x = 62[/tex]
Therefore, the third angle must have a measure of 62°.

Which graph shows a reflection of the rectangle across the horizontal dotted line?
Answers
Answer:
B
Step-by-step explanation:
The answer is B because if its being reflected its like symmetry horizontally
Sorry if this made no sense :c
Have a good day!
The correct option is Option D: The figure in Option D is reflection about the dotted horizontal line.
What is reflection?Reflection is the geometrical transformation of the figure about an axis, without changing the size and shape of the image in which every point is at same distance from the axis as in the reflected image.
Here the original image is in the 2nd quadrant.
the reflection axis is horizontal and situated in the 3rd and 4th quadrants.
So by reflecting about that axis without changing the size and shape of the image for which the distance of the original image from the axis will be equal to the distance of the reflected object from the axis.
As original image is in the 2nd quadrant the reflected will be drawn at the 3rd quadrant opposite to the original image.
Checking all the options only in Option B and option D have the reflected image at the 3rd quardant. But in Option B the reflected image is situated on the reflection axis which is against the rule of reflection.
Therefore The correct option is Option D: The figure in Option D is a reflection about the dotted horizontal line.

In a cinema theatre, why do we normally not hear echoes even though the sounds are loud?
Answers
Answer:
An echo is formed as a result of reflection of the original sound which returns to the listener. You might have experienced Echo in an EMPTY ROOM but no echo is produced after the room is occupied. To avoid echo from being produced the echo has to be absorbed. Echo in a cinema theatre is absorbed by the WALLS of the theatre.
They are not plain. The walls are corrugated or shaped to form tiny holes or empty spaces to ABSORB the ECHO. Modern Theatre's have ABSORBENT materials sticked to the walls of the theatre.
An echo is an unpleasant sound heard after a produced sound got reflected from a plain surface. It is majorly eliminated in a cinema theater by:
the use of sound absorbing materials in the construction of the wallsabsorption of sound waves by the body and cloths of viewers
Echo is a sound produced due to the reflection of a produced sound by a plain surface. Its continuous occurrence leads to reverberation. It causes distortion of produced sound which makes it unpleasant to hearing. Thus the need for a mechanism which would reduce it to a bearable level.
To reduce or eliminate echo, the walls of the cinema theater had been constructed with sound absorbing materials which may include special pads. These would have been incorporated into the walls, and would absorb most unwanted sounds produced in the theater.
Also the cloths worn by viewers absorbs some of the unwanted sound, thus assisting to indirectly reduce echo.

(0,7)
Answers
Answer:
What do you mean?
Step-by-step explanation:
Answer:
( 5, 0 )Step-by-step explanation:
x - 3y = 5
2x + y = 10 multiply by 3 to eliminate y and solve for x
x - 3y = 5
6x + 3y = 30 then add
7x = 35
simplify:
x = 35 / 7
x = 5
substitute x = 5 back into the eq.2
2x + y = 10
2(5) + y = 10
y = 10 - 10
y = 0
therefore the answer is ( 5, 0 )

2) choice A, theyre equal in length
3) Choice D, (-3,0) (-3, -3) (-1, -3)
4) Choice A, Clockwise 90- degree rotation
Step-by-step explanation:
The statements which describe A'B' is:
A'B' and AB are equal in length ⇒ (B)
Step-by-step explanation:
Let us take about reflication:
⇒ Reflections are mirror images, means the shape or the size of
the figure does not affect by reflection, think of "folding" the
graph over the y-axis or the x-axis
⇒ On a grid, you used the formula (x, y) → (-x, y) for a reflection in
the y-axis and used the formula (x, y) → (x, -y) for a reflection in
the x-axis.
In our question segment AB, where A = (1, 3) and B = (5, 3) is
reflected about the y-axis
By using the rule above
∴ A' =(-1, 3)
∴ B' = (-5,3)
∵ Reflection does not change the shape or the size of the original figure
∴ Line segment A'B' has the same length of line segment AB
The correct answer is:
A'B' and AB are equal in length
You can check your answer by finding the lengths of AB and A'B'
∵ The length of AB = 5 - 1 = 4 units
∵ The length of A'B' = -1 - (-5) = -1 + 5 = 4 units
∴ AB = A'B'
Note:
If the y-coordinates of two points are equal, then the line joining them is horizontal and its length is the difference between the x-coordinates of the two points.
