Answer:
A. 364 yards
Step-by-step explanation:
The distance between two points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)[/tex] on the coordinate plane is given as:
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The cone W, X, Y and Z form a rectangle.
The perimeter for the rectangle = 2(length + breadth)
[tex]Length=|WX|=\sqrt{(-38-(-38))^2+(53-(-53))^2}=106 \\\\Breadth=|XY|=\sqrt{(38-(-38))^2+(53-53)^2}=76[/tex]
Perimeter = 2(length + breadth) = 2(106 + 76) = 364 yards
The store bought a pair of shoes for $50 and sold it for $80. What percentage was the markup?
Answer:
37.5%
Step-by-step explanation:
The markup would be 37.5%. 80-50 = 30. If you set up the
proportion, is/of = %/100, it would be 30/80 = %/100. Multiply
30*100. = 3,000. Divide this by 80 and you get 37.5.

Cyndi has $55. Her sister has $115. Cyndi saves $10 per week. Her sister saves $6 per week. How many weeks will it
take for Cyndi and her sister to have the same amount of money? Write an equation and solve.
Answer: It will take 15 weeks for Cyndi and her sister to have the same amount of money.
Step-by-step explanation:
Given: Cyndi has $55. Her sister has $115.
Cyndi saves $10 per week. Her sister saves $6 per week.
Let x= Number of weeks.
Total amount of money Cyndi has = 55+10x (i)
Total amount of money sister has = 115+6x (ii)
From (i) and (ii) , we get
[tex]55+10x=115+6x\\\\\Rightarrow\ 10x-6x=115-55\\\\\Rightarrow\ 4x=60\\\\\Rightarrow\ x=\dfrac{60}{4}\\\\\Rightarrow\ x=15[/tex]
Hence, it will take 15 weeks for Cyndi and her sister to have the same amount of money.
What is the distance from QR?
Q
6n + 3
s
4n + 11
R
Answer:
The distance of QR is 54 units
Step-by-step explanation:
In the isosceles triangle, The height drawn from the vertex angle to the base bisects the base
In ΔPQR
∵ PQ = PR
∴ Δ PQR is an isosceles triangle
∵ P is the vertex angle
∵ QR is the base
∵ PS ⊥ QR
→ By using the fact above
∴ PS bisects QR
∴ S is the midpoint of QR
→ That means S divided QR into 2 equal parts QS and SR
∵ QS = SR
∵ QS = 6n + 3
∵ SR = 4n + 11
→ Equate them to find n
∴ 6n + 3 = 4n + 11
→ Subtract 4 n from both sides
∵ 6n - 4n + 3 = 4n - 4n + 11
∴ 2n + 3 = 11
→ Subtract 3 from both sides
∵ 2n + 3 - 3 = 11 - 3
∴ 2n = 8
→ Divide both sides by 2
∴ n = 4
→ Find the length of QS by substitute x in its expression by 4
∵ QS = 6(4) + 3 = 24 + 3
∴ QS = 27
∵ QS = SR
∴ SR = 27
∵ QR = QS + SR
∴ QR = 27 + 27
∴ QR = 54 units
∴ The distance of QR is 54 units
How do I find a table that represents Y as a function of X
Answer:
C: x: 5, 2, 6, 4, 1, 3; y: 2, 2, 2, 2, 2, 2
Step-by-step explanation:
Things that can represent a function of x has to be able to be shown in the form of a function, such as "y =" or "f(x) =". I'm guessing you're learning about linear lines, so I'm going to talk about this with linear lines.
A linear line must be straight and for y to be represented as a function of x, it has to have a constant increase or decrease for every x. Here is how to identify non-function lines:
- If there are different y values for the same x value
- If the points in order do not create a straight line
- If the points in order do not have a repeating pattern
To identify a function, look for:
- Straight lines
- An actual written function (such as "y =" or "f(x) =")
- A pattern on a table
Now, the pattern you're going to be looking for on a linear table is an addition or subtraction one for every x. If the x values are in order, then for every 1 x, there should be a constant addition or subtraction to the y.
Here's an example of a table that represents y as a function of x:
- X: 1 2 3 4 5
- Y: 3 5 7 9 11
- Pattern: +2 y for every x with constant 1
- X: 3 1 5 4 7
- Y: 9 3 15 12 21
- Pattern: +3 y for every x with constant 0
Here's an example of a table that doesn't represent y as a function of x:
- X: 1 2 3 4 5
- Y: 2 5 8 2 4
- Pattern: None
- X: 3 1 5 1 7
- Y: 1 7 8 9 4
- Pattern: None

Answer:
Table C
Step-by-step explanation:
A relation is not a function if any input value (x) is repeated.
A) 3 is a repeated x-value
B) 5 is a repeated x-value
C) no repeated x-values; the function you are looking for
D) 2 is a repeated x-value
A bag contains marbles. Some are blue and the rest are red. There are 3 blue marbles for every red marble. How many blue marbles are in the bag?
Answer: Doubling the red marbles means that each 2 red marbles will be replaced by 4 red marbles. So after doubling the red marbles for each 3 blue marbles there will now be 4 red marbles, giving a new ratio of 3:4.

Guys what is 8÷96 please
anwser I need to finish my homework toda.
Answer:
twelv
Step-by-step explanation:
12
Answer:
12
Step-by-step explanation:
Step 1:
Start by setting it up with the divisor 8 on the left side and the dividend 96 on the right side like this:
8 ⟌ 9 6
Step 2:
The divisor (8) goes into the first digit of the dividend (9), 1 time(s). Therefore, put 1 on top:
1
8 ⟌ 9 6
Step 3:
Multiply the divisor by the result in the previous step (8 x 1 = 8) and write that answer below the dividend.
1
8 ⟌ 9 6
8
Step 4:
Subtract the result in the previous step from the first digit of the dividend (9 - 8 = 1) and write the answer below.
1
8 ⟌ 9 6
- 8
1
Step 5:
Move down the 2nd digit of the dividend (6) like this:
1
8 ⟌ 9 6
- 8
1 6
Step 6:
The divisor (8) goes into the bottom number (16), 2 time(s). Therefore, put 2 on top:
1 2
8 ⟌ 9 6
- 8
1 6
Step 7:
Multiply the divisor by the result in the previousy step (8 x 2 = 16) and write that answer at the bottom:
1 2
8 ⟌ 9 6
- 8
1 6
1 6
Step 8:
Subtract the result in the previous step from the number written above it. (16 - 16 = 0) and write the answer at the bottom.
1 2
8 ⟌ 9 6
- 8
1 6
- 1 6
0
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 96 divided by 8 calculated using Long Division is:
12
0 Remainder

Solve the system using substitution. show work.
x=y−6
y=6−3x
Answer:
y=6
x=0
Step-by-step explanation:
X=(y-6)
y=(6-3x)
So For Y
y=6-3(y-6)
y=6-3y+18
add three so it would be 4y=6+18 which then equal 4y=24 then divide 4 then you'll have 6
and for X just plug in whats in (y)
x=(6-3x)-6
So again add 3x to both side to get 4x=6-6 which equal 0 then answer is 4x=0 divide 4 get 0
6. Which of the following lines is perpendicular to the line **
4y = -- 24 and passes through the point (6 - 2)
(A) y a 4x 22
(B) yax - 22
(C) y = 22
(D) y - 4x-22
(E) = 4x+18
Answer:b

what is the effect on the graph of the linear parent function, f (x) = x, when f ( x ) is replaced by f (x +5)
Answer:
When f(x) is replaced by f(x+5), it will shift the parent function '5 units' to the left.
Step-by-step explanation:
We know that when we add a number 'a' to the input of the function, it would move the parent function 'a' units to the left.In other words, the rule is:
f(x + a) will shift the parent function 'a units' to the left.Given the function
[tex]f(x)=x[/tex]
Thus, when f(x) is replaced by f(x+5), it will shift the parent function '5 units' to the left.
The effect on the graph of the linear parent function is shown in the attached diagram.In the graph, the red line is representing the parent function f(x) and the blue line is representing the effect on the graph i.e. f(x+5).
