What divides a design so that every point on one side of the line coincides
with a point on the other side of it?
A. Equator of symmetry
B. Point of symmetry
C. Line of symmetry
D. Symmetrical half life
The design that every point on one side of the line coincides with a point on the other side of it is Line of symmetry
What is Symmetry?Symmetry in mathematics means that when one shape is moved, rotated, or flipped, it looks exactly like the other shape.
A circle or band that divides a body's surface into two typically equal and symmetrical portions.
When a shape or item has a central point, point symmetry occurs when all points on the opposing sides are at the same distance from the centre.
The term "line of symmetry" refers to the fictitious axis or line that can be used to fold a figure into symmetrical halves.
It denotes that one half is the other half's mirror image.
Thus, the required design is Line of Symmetry.

Find the value of x on a triangle
Answer:
x = 25
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees.
90 + x+ 2x+15 =180
Combine like terms
105+3x = 180
Subtract 105 from each side
105+3x-105 = 180-105
3x =75
Divide each side by 3
3x/3 = 75/3
x = 25
Answer:
25°
Step-by-step explanation:
2x + 15° + x + 90 °= 180° ( being sum of angles of triangle)3x + 105° = 180 °3x = 180 °- 105°3x = 75° x = 25°hope it helps :)
Tiana uploaded 150 songs from her computer to her cell phone. These songs took up 300
megabytes of space on her phone. Each song took up the same amount of space.
How many megabytes do 25 of these songs take up?
Answer:
50mb
Step-by-step explanation:
So start with what you have 300/150 = 2 so each song took up 2mb of space, so 25 songs would take up 25x2= 50mb
The number of megabytes taken up by 25 songs is 50 megabytes.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
150 songs = 300 megabytes
1 song = 300 /150 megabytes
1 song = 2 megabytes ______(1)
Now,
Multiply 25 on both sides of (1).
25 songs = 25 x 2 megabytes
25 songs = 50 megabytes
Thus,
25 songs will take 50 megabytes.

Polygon A has an area of 18 square feet and Polygon B has an area of 98 square feet. If the two polygons are similar, and Polygon B has a side length of 14 feet, find the corresponding side length in Polygon A.
Answer:
6 feet
Step-by-step explanation:
Let the length of side length in polygon A be represented by x. Since the two polygons are similar, then it can be deduced that;
Area scale factor = [tex](linear scale factor)^{2}[/tex]
linear scale factor = [tex]\sqrt{Area scale factor}[/tex]
Area scale factor = [tex]\frac{98}{18}[/tex]
So that,
linear scale factor = [tex]\sqrt{\frac{98}{18} }[/tex]
= 2.3333
The length of side of polygon A = [tex]\frac{14}{2.3333}[/tex]
= 6.0085
Therefore, the corresponding side length of polygon A is 6 feet.

What is the equation for the lines that passes through the coordinates (2,7) and (0,1)
Answer:
(x1,y1) is (2,7)
(x2,y2) is (0,1)
Step-by-step explanation:
Point-slope form is:
(y-y1) = ( (y2-y1) / (x2-x1) )(x - x1)
y - 7 =( (-6)/(0-2) )(x-2)
y - 7 = 3x - 6
y = 3x + 1 [slope-intercept form]
Check:
Is (2,7) on the line:
7 = 3(2) + 1 ?
y = 7 ?yes
Is (0,1) on the line:
1 = 3(0) + 1 ?
1 = 1 ? yes
Answer:
y=3x+1
to find the slope, find the change in y/change in x
7-1=6
2-0=2
6/2=3
3 is your slope
your y intercept occurs when x=0, and that was given to you in the problem
(0,1)
your y int is 1
y=3x+1
