Answer: Think of it this way, symmetry is basically a mirror and you can better find the perimeter because you'll know that the sides are the same length
Step-by-step explanation:
Well if you have two sides that are symmetrical or an entire shape is symmetrical you can find the perimeter easier. So let's say two lines are symmetrical and one has the length of 2 the other one can also be two. If we have a symmetrical shape, then is would be a complete reflection.
A geometric object or form is symmetric when it can be broken up into two or more identical pieces and then placed in a systematic way.
what is symmetry ?The definition of symmetry is a proportionate and balanced similarity between two sides of an object, where one half is the mirror image of the other. For instance, certain geometric forms like, rectangle, and circle are symmetric along their respective axes of symmetry.
since the shape's two halves would perfectly match if you folded it along the line. The shape will also remain unchanged if a mirror were positioned along the line , a square has four lines of symmetry.
A geometric object or form is symmetric when it can be broken up into two or more identical pieces and then placed in a systematic way.

Tom's father is carpeting a rectangular room that has an area of 240 square feet. The width of the room is 15 feet. How long is the room?
Answer:
16 feet is the length of the room
Step-by-step explanation:
to find area, you do length x width. If you are trying to find L in L x W = A then you have to divide 240 by 15 to get 16 feet as the length

In an arboretum, the heights of five trees were 21 feet, 31 feet, 36 feet, 28 feet,
and 26 feet. What would be the height of the sixth tree if the mean height of the
six trees was 28 feet?
Answer:
26
Step-by-step explanation:
(21+31+36+28+26+x)/6=28
21+31+36+28+26+x= 28×6
142+x =168
x=168-142
x=26
The dimensions of a lawn shaped like a trapezoid are given in meters. 18 meters, 4 meters, 5 meters, 12 meters. What is the area of the lawn in square meters?
Answer:
the area of the lawn in square meters is 60 meters^2
Step-by-step explanation:
The computation of the area of the lawn in square meters is shown below
= 12 meters × 5 meters
= 60 meters ^2
Here we multiply the two sides so that the area of the lawn could be come
Hence, the area of the lawn in square meters is 60 meters^2

Suppose ABCD is a rhombus with AB = 12 inches. The midpoints of its sides are joined to form a quadrilateral. What type of quadrilateral is formed?
Answer:
A rectangle
Step-by-step explanation:
The given parameters are;
The quadrilateral ABCD is a rhombus;
The length of the sides of the rhombus = 12 inches
The lengths of the sides of a rhombus are equal
The opposite interior angles of the rhombus are equal
The length of each midpoint from the vertex = 12 in./2 = 6 in.
Therefore, we have;
The line joining the midpoints form a quadrilateral with the length of the opposite sides equal
The sum of the interior angles of the rhombus = 180°
From the diagram created with Microsoft Visio, we have;
4·a + 4·b + 360 = 4 × 180 = 360 + 360
4·a + 4·b = 360
a + b = 90°
We have;
The interior angles of the quadrilateral formed = x
a + b + x = 180° Sum of angles on a straight line
∴ x = 180° - (a + b) = 180° - 90° = 90°
x = 90°
Therefore, the interior angles of the quadrilateral formed = 90°
The quadrilateral formed having equal opposite sides, and all interior angle of 90° each is a rectangle
find the geometric mean of 50 and 4
Mean also means average.

Sean and his cousin are playing a game where they pick up colored sticks. Sean currently has 50 points and likes to pick up the white sticks, earning 2 points every turn. His cousin just lost all her points on the previous turn, and has a strategy to catch up by getting all the purple ones, earning 12 points per turn. In a certain number of turns, the score will be tied. How long will that take?
Answer:
It would take 5 turns
Step-by-step explanation:
It is estimated that 78% of drivers use their turn signal. Part A: What is the probability that exactly 3 drivers use their turn signal if a police officer pulls over five drivers? (5 points) Part B: What is the probability the next driver using their turn signal that the police officer pulls over if the fifth driver? (5 points) (10 points)
Answer:
0.2297 ;

Step-by-step explanation:
p = 0.78
1 - p = 0.22
P(x = 3)
Using the binomial distribution formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 3) = 5C3 * 0.78^3 * 0.22^2
P(x = 3) = 10 * 0.78^3 * 0.22^2
P(x = 3) = 0.2297
Rob is saving to buy a new MP3 player. For every $12 he earns babysitting, he saves $9. On Saturday, Rob earned $36 babysitting. How much money did he save?
Answer:
$27
Step-by-step explanation:
Set up a proportion where x is the amount of money he saved:
[tex]\frac{12}{9}[/tex] = [tex]\frac{36}{x}[/tex]
Cross multiply and solve for x:
12x = 324
x = 27
So, he saved $27
