Which is a scaled copy of Polygon A?Identify a pair of corresponding sides and a pair of corresponding angles. Compare the areas of the scaled copies.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the polygon A (and other possible polygons to select from) are not given. So, I will answer on a general term.
Assume that Polygon A is a rectangle of dimension 2ft by 5ft.
[tex]Length = 2ft[/tex] [tex]Width = 5ft[/tex]
Possible scaled copies can be gotten by multiplying the dimension of A by the same scale factor.
Take for instance, the scale factor k is:
[tex]k = 3[/tex]
A scaled copy of polygon A (say polygon B) is: 6ft by 15ft
This is gotten by:
[tex]Length = 2ft * 3 = 6ft[/tex] [tex]Width = 5ft * 3 = 15ft[/tex]
The area of A is:
[tex]Area = 2ft * 5ft = 10ft^2[/tex]
The area of B is:
[tex]Area = 6ft * 15ft = 90ft^2[/tex]
See attachment for polygons
Comparison
The area of B is greater than the area of B.
This method can be applied to scale factors

Answer:
26. B(t) = 500·1.075^t; B(6) ≈ $772
27. G(t) = 70·0.72^t; G(3) ≈ 26 g
Step-by-step explanation:
The equation with the plus sign is used when the value is increasing. The minus sign is used when the value is decreasing. The 'a' in each equation is the initial value.
__
26. B(t) = 500·1.075^t
B(6) = 771.65
The balance after 6 years is about $772.

2). Write an equation and solve. You will not be given credit for your answer if you do not include your equation! This month's cell phone bill was for $15.27 more than last month's cell phone bill. If this month's phone bill is for $72.50, how much was last month's cell phone bill?
Answer:
Equation is: x+15.27 = 72.50Solution to that equation: x = 57.23Interpretation: Last month's phone bill was $57.23========================================================
Explanation:
We'll make x the value of last month's phone bill. So if lets say x = 50, this means that last month's phone bill was $50. We don't know yet if x = 50 is the actual solution or not.
We're told that "This month's cell phone bill was for $15.27 more than last month's cell phone bill". This means this month's bill, in terms of x, is x+15.27 dollars. Whatever x is, we add 15.27 onto it getting this month's bill. This works because x is really a placeholder for a number.
Going back to x = 50, that would mean this months bill is x+15.27 = 50+15.27 = 65.27 dollars. We can see that we don't reach 72.50 that we're told the current months bill actually is. Since we don't have a match, this means x = 50 is too small. We can guess and check our way to hopefully land on the answer. However, using algebra is the most efficient method.
----------
The equation we need to solve is: x+15.27 = 72.50
This is because x+15.27 represents this month's bill and so does the 72.50, as your teacher gave in the instructions.
To solve this equation, we'll undo the "plus 15.27" to isolate x fully. The opposite of addition is subtraction. We'll subtract 15.27 from both sides
x+15.27 = 72.50
x+15.27-15.27 = 72.50-15.27
x = 57.23
Last month's phone bill was $57.23
As a check, adding 15.27 onto last month's bill should get us to 72.50
x+15.27 = 57.23+15.27 = 72.50
It works out, so we've confirmed the answer.
If 2 = 6, what is the degree measure of 5?
A. 80
B. 220°
C. 60°
D. 120°
Answer:
60°
Step-by-step explanation:
We know that 2 and 6 = 60 degrees, so we add 60 + 60 which equals 120, now subtract 120 by 180 and you get 60 degrees.

The decimal form of 1/3 is a repeating decimal. Are all the multiples of 1/3 also repeating decimals? Explain.
plz help
Answer:
No.
Step-by-step explanation:
1=3*1/3
2=6*1/3
3=9*1/3
......
Yes, All the multiples of 1/3 also repeating decimals.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The decimal form of 1/3 is a repeating decimal.
Now,
Since, The decimal form of 1/3 is a repeating decimal.
As, 1 / 3 = 0.33333...
And, Some of the multiples of 1/3 are;
1 / 3 = 1×2 / 3×2
= 2 / 6
= 0.33333....
And, 1 / 3 = 1×3 / 3×3
= 3 / 9
= 0.33333....
1 / 3 = 1×4 / 3×4
= 4 / 12
= 0.33333....
Thus, Yes, All the multiples of 1/3 also repeating decimals.

Answer:
c) 190.6 ft
we first must calculate the height of the tree, and let's give it T
T = tan(47) × 130
T = 1.07.. × 130
T = 139.40.. ft
now we will calculate the distance between the top of the tree and the tip of the casted shadow, and let's give it D
D² = 130² + 139.40²
D² = 16900 + 19434.57..
D² = 36334.57..
D = √36334.57..
D = 190.6 ft

A broken pottery shard found at an archaeological dig has a curved edge. Find the diameter of the
original plate. (Use the fact that the diameter PR is the perpendicular bisector of chord AB.) If necessary,
enter your answer as a simplified proper fraction or mixed number.
Answer: 18 1/2 inches
Step-by-step explanation:
Applying the segments of chords theorem, the diameter of the original plate is: PR = 18 ⅛ inches.
What is the Segments of Chords Theorem?Based on the segments of chords theorem, the following equation is true:
(AQ)(QB) = (PQ)(QR)
Plug in the values
(9)(9) = (8)(QR)
QR = 81/8
QR = 10 ⅛ inches.
Diameter PR = QR + PQ
Diameter PR = 10 ⅛ + 8
Diameter PR = 18 ⅛
