I can confirm that it is A as I took the test and got 100%.
The length of side A in the new parallelogram will be [tex]2[/tex] cm.
What is Scale Factor ?Scale Factor is defined as the ratio of size of new image formed to the size of old image.
We have,
A parallelogram with side lengths [tex]18[/tex] centimeters and [tex]45[/tex] centimeters.
And,
A second parallelogram with side lengths [tex]A[/tex] and [tex]5[/tex] centimeters.
Now,
Scale Factor [tex]=\frac{size\ of\ new\ image}{size\ of\ old\ image}[/tex]
So,
Now, Comparing sides ,
We get,
Scale Factor [tex]=\frac{45}{5}=9[/tex]
i.e. the second parallelogram have Scale Factor of [tex]9[/tex].
So,
Other sides of both parallelograms will be of same Scale Factor.
i.e.
[tex]=\frac{18}{A} =9[/tex]
⇒
[tex]A=2[/tex] cm
Hence, we can say that the length of side A in the new parallelogram will be [tex]2[/tex] cm.

What's the y intercept and slope?
Answer:
The slope is 4
The y-intercept is 3 OR (0, 3)
Step-by-step explanation:
Points on the graph: ( -1, -1) and (0,3)
Slope:
m=(y2-y1)/(x2-x1)
m=(3+1)/(0+1)
m=4/1
m = 4
Point slope-intercept:
y - y1 = m(x - x1)
y + 1 = 4(x + 1)
y + 1 = 4x + 4
y = 4x + 3

Each marble bag sold by Henry's Marble Company contains 5 purple marbles for every 4 orange marbles. If a bag has 20 orange marbles, how many purple marbles does it contain?
Answer:
25
Step-by-step explanation:
If it's 5 for every 4 and the bag has 20, 4*5 = 20 and you'd have to do that to the 5 as well to get 5*5=25.

Taylor climbed a tree and is sitting on one of the branches deciding if she wants to jump. She weighs 45 kilogram and is sitting 10 meters from the ground. What is her potential energy?
Answer:
Her potential energy is approximately 4481 J.
Step-by-step explanation:
Because the formula for potential energy is PEg = 9.81 * mass * height, just plug in the knowns. After you plug those in, you will get the potential energy as 9.81 * 450, which is approximately 4481 J.

what is the distance between -3,500 and 2,000 feet
Answer: if you take 2,000- (-3,500) you get 5,500 ft, making this the distance. Also, think about it this way 2,000 is 2,000 ft from 0, and then there is another 3,500 past zero, putting these together makes the amount of space they are away from each other in total.
Note that when subtracting a negative it becomes positive, using the keep change change rule 2,000 - (-3,500) becomes 2,000 + 3,500
find the 9th term of the geometric sequence 6,-24,96...
Answer:
A9 = 393216
Step-by-step explanation:
the first thing that will help you solve this question is finding the common ratio between each terms
the first thing that I like to do that usually helps is to take the second term (-24) and divide it by the first term (6) --> this will usually help you spot the common ratio fairly quickly
in your case, the common ratio is -4
- you can also check this by following my note above and then multiplying the second term by the common ratio to see if it matches the third term, which it does!
so now you can go about this two different ways
1. solve directly for the 9th term
2. use the nth term formula for geometric sequences
METHOD 1:
if you continue to multiply by -4 to solve for each term you would end up with:
6, -24, 96, -384, 1536, -6144, 24576, -98304, 393216
and you will recieve 393216 as your answer
METHOD 2:
the nth term formula is An = A1*r^(n-1)
where An = the nth term of the sequence
A1 = first term of the sequence (6)
and r = common ratio
using this formula, you would get:
A9 = 6(-4)^8
A9 = 393216

the radius of a circle is 8 what is the area of the circle? pls show work
Answer:
201.06
Step-by-step explanation:
A=πr2=π·82≈201.06193
Answer:
201.14 ≈ 201 unit²
Step-by-step explanation:
Area of circle = πr², where π is either 3.14 or 22/7 or 355/113. Mostly it is 22/7.
=> area of circle = (22/7) (8)² unit²
=> area of circle = (22 x 64)/7 unit²
=> area of circle = 201.14 unit²
If we take π = 3.14
=> area of circle = (3.14)(8)² = 200.96 unit²

Answer:
∠A = 77°
Step-by-step explanation:
Given:
Inscribe quadrilateral
Opposite angles
∠A = (2x + 9)°
∠B = (3x + 1)°
Find:
Value of ∠A
Computation:
We know that in Inscribe quadrilateral sum of Opposite angles are 180
So,
(2x + 9)° + (3x + 1)° = 180°
5x + 10 = 180
x = 34°
So,
∠A = (2x + 9)°
∠A = 2(34) + 9°
∠A = 77°

A train leaves at 08:36 and arrives at 10:57. It travelled at an average speed of 85 km/h.
How far did it travel? Give your answer in km to 1DP.
Answer:
199.8 km to the 1 decimal point
Step-by-step explanation:
8:36 to 9:00 is 24 min
9:00 to 10:00 is 60 min
10:00 to 10:57 is 57 min
That's a total of 24 + 60 + 57 = 141 min = 141/60 hr.
d = rt = 141/60(85) = 199.8 km to the 1 decimal point

Alejandra plans to sew fringe on a scarf. The scarf is shaped like a rectangle. The length of the scarf is 44 inches. The width is one half the length.
Answer:
Total fringe needed = 132 inches
Step-by-step explanation:
P.S - The exact question is -
Given - Alejandra plans to sew fringe on a scarf. The scarf is shaped like a rectangle. The length of the scarf is 44 inches. The width is one half the length.
To find - How much fringe does Alejandra need?
Proof -
Total fringe needed = Perimeter of the rectangle.
Now,
We know that,
Perimeter of the Rectangle = 2(Length + Width)
Now,
Given that,
Length = 44 inches
Width = one half the length
= [tex]\frac{1}{2}[/tex] × 44 = 22 inches
⇒Width = 22 inches
∴ we get
Perimeter of the Rectangle = 2(44 + 22)
= 2(66) = 132 inches
⇒Perimeter of Rectangle = 132 inches
∴ we get
Total fringe needed = Perimeter of the rectangle = 132 inches
⇒Total fringe needed = 132 inches
