The comparison of shoes placed on the floor by Helena next to each other change from reflection to translation.
What do you mean by reflection?The reflection of a plane or shape is flipping the original figure with respect to a reference line.
The rule of reflection are given below,
Reflection about x-axis (x,y)-->(x,-y)Reflection about y-axis (x,y)-->(-x,y)Before training for the obstacle course, Helena bought a new pair of athletic shoes.
She placed the shoes on the floor next to each other and noticed that the right shoe looked just like a reflection of the left shoe. This is because, the separating line works as the symmetry line between both the shoes.Now she had accidentally purchased two left shoes. Now, if she puts a left shoe to another left shoe, then it looks like the translated image of the first shoe.
Hence, the comparison of shoes placed on the floor by Helena next to each other change from reflection to translation.

50 points. Thanks
Answer:
x = 7
Step-by-step explanation:
From the figure, we can see the figure is a right triangle. To find the value of x, we need to apply the Pythagorean Theorem.
===============================================================
Solving :
⇒ (x)² + (24)² = (x + 18)²
⇒ x² + 576 = x² + 36x + 324
⇒ 36x = 576 - 324
⇒ 36x = 252
⇒ x = 252/36
⇒ x = 7
Apply Pythagorean theorem
H²-P²=B²(x+18)²-x²=24²(x+18+x)(x+18-x)=576(2x+18)(18)=5762x+18=322x=14x=7Help me on this math problem please!! DUE TONIGHT!!

A rectangular garden measures by 30ft and 40ft. Surrounding (and bordering) the garden is a path 3ft wide. Find the area of this path. Be sure to include the correct unit in your answer
Answer:
312 ft²
Step-by-step explanation:
Area of the garden = Length x Width
Area of the garden = 30 x 40 = 1200ft²
Length of the garden and path = Length of the garden + 3 ft on both sides
Length of the garden and path = 30 + 3 + 3 = 36 ft
Width of the garden and path = Width of the garden + 2 ft on both side
Width of the garden and path = 40 + 3 + 3 = 46 ft
Area of the garden and path = Length x Width
Area of the garden and path = 36 x 46 = 1512 ft²
Area of the path = Area of the garden and path - Area of the garden
Area of the path = 1512 - 1200 = 312 ft²
Answer: 312 ft²

The square of the altitude is equal to the product of the base of the triangles
Triangular altitude theoremThe square of the altitude is equal to the product of the base of the triangles. The length of line segment GJ is 8units
According to the theorem;

HJ + JF = 16
Since HJ = JF, hence
HJ = JF = 8

Which triangle is not similar to the other two triangles?
Answer:
First choice top-down
Step-by-step explanation:
The Similarity Theorem Side-Angle-Side it can be checked here to see what triangles are similar.
All 3 triangles have 2 congruent sides so the triangles are all isosceles.
The base angles of isosceles triangles are congruent so knowing this and that the sum of angles in a triangle is 180° we can calculate the measure of all angles.
180-20 = 160; 160/2 = 80°
180-30 = 150; 150/2 = 75°
Now we can conclude that Δ JLK is not similar with Δ MNO ≈ ΔPRQ

A, B and C form a triangle where ∠BAC = 90°
AB = 4.4mm and BC = 14.8mm
Find the length of AC, giving your answer rounded to 1 decimal place.
Answer:
............ .. .......
Answer:
14.1 mm
Given:
∠BAC = 90° (angle A should be 90°)
AB = 4.4mm
BC = 14.8mm
See the diagram given below.
Solving using Pythagoras Theorem: a² + b² = c²
x² + 4.4² = 14.8²
x = 14.8² - 4.4²
x = 219.04 - 19.36
x = 199.68
x = √199.68
x = 14.13 ≈ 14.1 mm (rounded to 1 decimal place)

∘
and m\angle B=(6x+27)^{\circ}∠B=(6x+27)
∘
, then find the measure of \angle A∠A.
78 is the answer
Step-by-step explanation:
The two angles are complementary so m<A + m<B = 90
we are given m<A = 3x + 9 and m<B = x - 11
substituting we get 3x + 9 + x - 11 = 90
4x - 2 = 90
4x = 92
x = 23
m<A = 3x + 9 = 3(23) + 9 = 78

Which expression is a factor of 12x2 29x – 8? x – 8 2x – 1 3x 8 4x 1
The factorization of the given expression is:
p(x) = (x - 2.66)*(x - 0.25)
Which expression is a factor?We have the quadratic equation:
12x^2 + 29x - 8
To get the factors we need to find the roots, then we use Bhaskara's formula:
[tex]x = \frac{-29 \pm \sqrt{29^2 - 4*(-8)*12} }{2*12} \\\\x = \frac{-29 \pm 35}{24}[/tex]
Then the solutions are:
x = (-29 + 35)/24 = 0.25
x = (-29 - 35)/24 = -2.66
Then the factors of the expression are:
(x - 2.66) and (x - 0.25)

What is the sum of this question
Answer:
C. 7x + 45
Step-by-step explanation:
To start answering this question, let's first distribute the 6 * ( x + 7 ) so that we can add like terms to simplify.
So let's multiply the 6 out to the ( x + 7 ) to get ( 6x + 42 ).
Now the complete expression reads: 6x + 42 + ( x + 3 )
With this, we can add all the like terms( 6x and x, and 42 and 3) together.
So we end up with 6x + x + 42 + 3 = 7x + 45
So the correct answer is C. 7x + 45

There are 20 students on the student council at Nina's school. Eight of the students are in Nina's math class, 6 of the students are in her science class, and 4 students are in both her math and science classes.
If 2 members of the student council are randomly chosen, what is the probability that both are in Nina's math or science class?
Step-by-step explanation:
out of the total possibilities of 20 student council members, 8 are in Nina's math class, and 6 are in Nina's science class.
as I understand the given information, out of these 14 council members, 4 are in her math and in her science class. but this is then irrelevant for the question (and do not add more possibilities), as these 4 are already covered by the 8 and 6 in her individual classes.
remember, a probability is always
desired cases / possible cases
so, let's pick the first random choice :
the probabilty to pick one that is either in her math or her science class is
14/20 = 7/10
because there are 20 total possibilities to pick from, and 14 of these 20 are in at least one of her classes.
now let's pick the second one.
I assume the first pick has not been returned to the pool and cannot be picked a second time.
so, this time we have therefore only 19 total choices, and 13 of them are in at least one of Nina's classes.
so, the probability for the second pick is
13/19
so, the probability that both picks are in at least one of her classes is then the combination of both probabilities (they have to happen together) :
7/10 × 13/19 = 91/190 = 0.478947368...
