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

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.

What is the measure of angle w? Type the number only. Do not type the word degrees.
Hint: The total is 360 degrees. Subtract the other 3. Remember that the little square in the corner equals 90 degrees.
Answer:
w = 34°
Step-by-step explanation:
Every quadrilateral is equal to 360 degrees. If you know 3 out of the 4 angles, then what you need to do is add up each angle and subtract the sum from 360 to find the remaining angle.
90 + 90 + 146 = 326
360 - 326 = 34
w = 34
Fill in the missing amounts in the balance sheet after the following transactions.
You start with $3,500 in cash and in owner's equity.
a. You sell product purchased for $750 for $1,525.00
b. You purchase equipment for $500.
c. You pay the rent by check for $450.
d. You receive next month's power bill for $155.00
Assets Liabilities and Owner's Equity
Cash $
Accounts Payable $
Equipment $ 500.00 Owner's Equity: Investment $
Total Assets $
Total Liabilities and Owner's Equity $
Answer:
Cash- $3,325.00
Total Assets- $3,825.00
Accounts payable- $155.00
Owners Equity- $3,670.00
Total- $3,825.00
The accounting equation as per accounting principle is that Assets balance on any date is equal to balance of liabilities and owner's equity. So the cash balance on period end date is $3325.00
What is an accounting equation?The entire assets of a corporation are equal to the sum of its liabilities and shareholders' equity, according to the accounting equation. The basic idea behind the double-entry accounting system is that assets, liabilities, and equity have a clear relationship with one another.
a) So the balance of cash = $3,500 - $750 + $1,525.00 - $500 - $450 - = $3325.
b) Balance of Accounts Payable = $155.00 = Outstanding power bill.
c) Equipment $ 500.00.
d) Investment = $0.00
E) Total Assets = $ 3825 = cash + Equipment +
F) Total Liabilities = $3825 = Owner's Equity + Accounts Payable
G) Owner's Equity = $3,670.00 = $3,500 + $775 - $155 - $450
Therefore the amount of cash and owners' equity of balance sheet can be solved by the use of accounting equation.

230% of some number is 48.2. what is the number?
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

Answer:
4 is c; 5 is a
Step-by-step explanation:
Given points for 4: (7, 2), (11, 5)
Given info for 5: (-2, -8); slope of 3
point-slope formula: y2 - y1 = m(x2 - x1)
Plugging in points: 5 - 2 = m(11 - 7)
Now we solve for m.
3 = m4
Final step: divide both sides by 4
Answer: m = 3/4
Second equation!
Plug into point-slope formula: y + 8 = 3(x + 2)
Distributive property of equality to eliminate parentheses
y + 8 = 3x + 6
Get y by itself by subtracting 8 to both sides
y = 3x - 2

"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

Edgar opened a deposit account. In the first month, he made an initial deposit of $3200, and plans to contribute an additional $175 every month. The account does not pay any interest. After how many months will he have a total of $6000?
Answer:
16 months
Step-by-step explanation:
let m = number of months
6000 = 3200 + 175m
2800 = 175m
m = 2800/175
m = 16
Answer:
16 months
Step-by-step explanation:
First I will subtract how much he has already paid.
6000 - 3200 = 2800.
Now to find how many months it will take to get a total of 2800 dollars we must divide.
[tex]2800 \div 175[/tex]
= 16
this means that an additional 16 months will be needed to reach the total of 6000 dollars.
