Segment GH underwent a sequence of two rotations around the same center. The original length of GH is 7 meters. What is the length of the segment after the sequence of rotations?
Answer:
[tex]GH = 7\ meters[/tex]
Step-by-step explanation:
Given
[tex]GH = 7\ meters[/tex]
Required
Length of GH after two rotations
In transformations, when a point, shape, line or line segment is rotated; the orientation and location of the point, shape, line or line segment change.
However, the length of the point, shape, line or line segment remains the same.
This is to say that:
After line segment GH is rotated twice, its length will remain unchanged.
Hence:
[tex]GH = 7\ meters[/tex]

which system of equations intersect at point A in this graph y = 10x - 1
y=-3x - 5
y = 4x + 9
y=-3x - 5
y = 2x + 5
y=x-1
y = 2x + 5
y = 5x + 11
y = 3x + 7
y=-x-1
Answer:
y = 4x + 9, y = -3x - 5
y = 2x + 5, y = 5x + 11
and y= 3x + 7, y = -x - 1
I just did this on Plato/Edmentum xD
The system of equations that intersect at point A = (-2, 1) is:
y = 4x + 9
y = -3x - 5
y = 2x + 5
y = 5x + 11
y = 3x + 7
y = -x - 1
We have,
Let's substitute the coordinates (-2, 1) into each equation to find the correct system of equations:
y = 10x - 1
Substituting (-2, 1):
1 = 10(-2) - 1
1 = -20 - 1
1 = -21 (Not satisfied)
y = 4x + 9
Substituting (-2, 1):
1 = 4(-2) + 9
1 = -8 + 9
1 = 1 (Satisfied)
y = -3x - 5
Substituting (-2, 1):
1 = -3(-2) - 5
1 = 6 - 5
1 = 1 (Satisfied)
y = 2x + 5
Substituting (-2, 1):
1 = 2(-2) + 5
1 = -4 + 5
1 = 1 (Satisfied)
y = x - 1
Substituting (-2, 1):
1 = -2 - 1
1 = -3 (Not satisfied)
y = 5x + 11
Substituting (-2, 1):
1 = 5(-2) + 11
1 = -10 + 11
1 = 1 (Satisfied)
y = 3x + 7
Substituting (-2, 1):
1 = 3(-2) + 7
1 = -6 + 7
1 = 1 (Satisfied)
y = -x - 1
Substituting (-2, 1):
1 = -(-2) - 1
1 = 2 - 1
1 = 1 (Satisfied)
Thus,
The system of equations that intersect at point A = (-2, 1) is:
y = 4x + 9
y = -3x - 5
y = 2x + 5
y = 5x + 11
y = 3x + 7
y = -x - 1

Sarah is a computer engineer and manager and works for a software company. She receives a
fixed annual increase in the number of projects she handles each year. She worked on 129
projects in the fourth year of her employment and 207 projects in her tenth year.
(a) How many projects did Sarah work on in her first year?
(b) If a project pays her $500 on average,
I. How much did she earn in her twelfth year?
II. How much did she earn in total in her first 12 years with the company
Answer:
a) Number of projects in the first year = 90
b) Earnings in the twelfth year = $116500
Total money earned in 12 years = $969000
Step-by-step explanation:
Given that:
Number of projects done in fourth year = 129
Number of projects done in tenth year = 207
There is a fixed increase every year.
a) To find:
Number of projects done in the first year.
This problem is nothing but a case of arithmetic progression.
Let the first term i.e. number of projects done in first year = [tex]a[/tex]
Given that:
[tex]a_4=129\\a_{10}=207[/tex]
Formula for [tex]n^{th}[/tex] term of an Arithmetic Progression is given as:
[tex]a_n=a+(n-1)d[/tex]
Where [tex]d[/tex] will represent the number of projects increased every year.
and [tex]n[/tex] is the year number.
[tex]a_4=129=a+(4-1)d \\\Rightarrow 129=a+3d .....(1)\\a_{10}=207=a+(10-1)d \\\Rightarrow 207=a+9d .....(2)[/tex]
Subtracting (2) from (1):
[tex]78 = 6d\\\Rightarrow d =13[/tex]
By equation (1):
[tex]129 =a+3\times 13\\\Rightarrow a =129-39\\\Rightarrow a =90[/tex]
Number of projects in the first year = 90
b)
Number of projects in the twelfth year =
[tex]a_{12} = a+11d\\\Rightarrow a_{12} = 90+11\times 13 =233[/tex]
Each project pays $500
Earnings in the twelfth year = 233 [tex]\times[/tex] 500 = $116500
Sum of an AP is given as:
[tex]S_n=\dfrac{n}{2}(2a+(n-1)d)\\\Rightarrow S_{12}=\dfrac{12}{2}(2\times 90+(12-1)\times 13)\\\Rightarrow S_{12}=6\times 323\\\Rightarrow S_{12}=1938[/tex]
It gives us the total number of projects done in 12 years = 1938
Total money earned in 12 years = 500 [tex]\times[/tex] 1938 = $969000

"Triangles ABC, EFD, and GHI are all similar. The side lengths of the triangles all have the same units. find the unknown side lengths.
would be useful if you had an explanation on how you got the answer thanks this is my hw need it done by 3pm today
The unknown side lengths are
Large triangle 10
Medium triangle 2
Small triangle 12/5 or 2.4
Step-by-step explanation:
EFD to ABC is 0.4 or 2/5
EFD to GHI is 0.24 or 6/25
ABC to GHI is 0.6 or 6/10
The side length of c is 2.
The side length of d is 10.
The side length of e is 10.
The side length of h is 2.4.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Triangles ABC, EFD, and GHI are all similar.
The side lengths of the triangles all have the same units.
This means,
The ratio of the corresponding sides of the two triangles is the same.
Now,
ΔABC and ΔGHI
4/(12/5) = 4/h = c/ (6/5)
20/12 = 4/h = 5c/6
We will consider 20/12 = 4/h.
20/12 = 4/h
5/12 = 1/h
h = 12/5
h = 2.4
We will consider 20/12 = 5c/6
20/12 = 5c/6
4/2 = c
c = 2
Now,
ΔABC and ΔEFD
4/e = 4/d = c/5
4/e = 4/d = 2/5
Consider 4/e = 2/5
4/e = 2/5
2/e = 1/5
e = 10
Consider 4/d = 2/5
4/d = 2/5
2/d = 1/5
d = 10
Thus,
The side length are:
c = 2
d = 10
e = 10
h = 2.4

If you have 6 candy bars and and you cut it in half 3 times what is the quotient.
Answer: 48
Step-by-step explanation:
I’m pretty sure
Answer:
24 pieces
Quotient: 2
Step-by-step explanation:
This is the answer because:
1) If you cut one candy bar into half three times, there will be 4 pieces.
2) Then, just multiply 6 and 4 together to know how many pieces there are together:
6 x 4 = 24
Therefore, the answer is 24 pieces.
3) In order to find the quotient, just divide 6 and 3:
6 ÷ 3 = 2
Therefore, the quotient is 2.

Astorepays$55foracoat.Thestoremarksupthepriceby40%.Whatistheamountofthemark-up?
The price of the coat after a 40% increase in price will be $77.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
A store pays $55 for a coat. The store marks up the price by 40%. Then the marked price is calculated as,
P = $55 x (1 + 0.40)
P = $55 x 1.40
P = $77
The price of the coat after a 40% increase in price will be $77.
