Answers
Answer:
Rectangle has both line and rotational symmetry
The Z has line symmetry
The trapezoid lookin thing has none
Rectangle has both line and rotational symmetry, the Z has line symmetry and the trapezoid has none of the symmetry.
What is Coordinate Geometry?A coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.
Lines of symmetry are mixed up with rotational symmetry.
A line of symmetry divides the shape equally into two symmetrical pieces.
A rotational symmetry is the number of times a shape fits into itself when rotated around its centre.
Rectangle has both line and rotational symmetry
The Z has line symmetry
The trapezoid has none of the symmetry.
Therefore, Rectangle has both line and rotational symmetry, the Z has line symmetry and the trapezoid has none of the symmetry.

Answers
Hi!
I'm Happy to help you today!
The answer to this question would be 30!
This is because to find the mean you have to add everything up, then divide it by how many number's there are so for this problem it is:
30 + 45 + 25 + 25 + 35 + 5 + 40 + 35 + 40 + 20 = 300
Then Divide!
300 ÷ 10 = 30
So 30 is your answer!

1) Tanya is buying edging for a triangular flower garden she plans to build in her backyard. If the lengths of the three pieces of edging that she purchases are 13 feet, 10 feet, and 7 feet, will the flower garden be in the shape of a right triangle ?
Answers
Answer:
• In a right triangle, the two sides adjacent to the
right angle are known as the _________, or
______ and ______.
• The side opposite from the right angle
is called the ___________________, or ______.
• The hypotenuse is always the _______________ side of a right triangle.
Step-by-step explanation:
Answer:
The Flower Garden is not in the shape of a right Δ
Step-by-step explanation:
~ To prove that this garden is in the shape of a right triangle, it can be done so through contradiction ~
Pythagorean Theorem is applied to a right triangle, so we can say that the two legs are 10 and 7 feet, the hypotenuse being 13, knowing it is the longest side;
a^2 + b^2 = c^2,
10^2 + 7^2 = 13^2,
100 + 49 = 169,
149 ≠ 169,
So the Flower Garden will not be in the shape of a right Δ

Lei pre sold 32 carnations for a fundraiser, then she sold c more carnations on the day of the fundraiser. She earned 0.25 dollars for each carnation she sold. The expression 8+ 0.25c describes how much money Lei earned for the fundraiser. We can also use the expression 0.25(32+c) to represent the same quantity. Help me Create another Expression please.
Answer I WILL GIVE BRAINLIEST!
Answers
Answer: [tex]0.5 * (16 + 0.5c)[/tex]
Step-by-step explanation:
Creating identical expressions involves changing quantities in a way that preserves the end values specified in the equation.
For instance, if Lei sold 4 carnations:
[tex]8 + 0.25 (4) = 9\\\\0.25 * (32 + 4) = 9[/tex]
In the second equation listed, the expression (8 + 0.25c) was multiplied by 4, then by 0.25, for a total multiplicand of 1.
You can make a third equation through the same method. I'll multiply (8 + 0.25c) by 2, and then multiply that expression by 0.5 to keep the multiplicand unchanged:
[tex]0.5 * (16 + 0.5c)[/tex]
If Lei sold 4 carnations:
0.5 * (16 + 2) = 9
This equation represents the same quantities as the other equations.

pages does Stephen read each week than Alice?
20
70
o
10
Answers
Answer:
10
Step-by-step explanation:
Stephen 278 pages in 7 weeks. Divide 278 by 7 to get 39.71 pages per week. 39.71 rounds up to 40, and 40 is about 10 more than 31.
There are more 9 pages does Stephen read each week than Alice.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Stephen reads 278 pages in 7 weeks.
And, Alice reads 31 pages each week.
Here, Stephen reads 278 pages in 7 weeks.
Hence, Number of pages read in 1 week = 278 / 7
= 40
And, Alice reads 31 pages each week.
Thus, Number of more pages Stephen read each week than Alice is,
⇒ 40 - 31
⇒ 9

Answer:
∠ A = 31.3°, ∠ C = 58.7°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin A = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{13}{25}[/tex] , thus
∠ A = [tex]sin^{-1}[/tex] ([tex]\frac{13}{25}[/tex] ) ≈ 31.3° ( to the nearest tenth )
The sum of the 3 angles in a triangle = 180° , thus
∠ C = 180° - (90 + 31.3)° = 180° - 121.3° = 58.7°
