7 cm
9.5 cm
6.5 cm
The perimeter and the area of the composite figure are 29 centimeters and 49.5 square centimeters, respectively.
How to determine the perimeter and the area of the figure
In this problem we have the representation of a composite figure, the result of the combination of a rectangle and a triangle. The perimeter of the figure is the sum of the sides and the area of the composite figure is the result of suming the areas of the rectangle and triangle:
Rectangle
A = b · h
Triangle
A = 0.5 · b · h
Where:
b - Baseh - HeightA - AreaAnd the perimeter and the area of the composite figure are now computed:
Perimeter
p = 6 cm + 7 cm + 6.5 cm + 9.5 cm
p = 29 cm
Area
A = 0.5 · (6 cm) · (2.5 cm) + (6 cm) · (7 cm)
A = 7.5 cm² + 42 cm²
A = 49.5 cm²

Parallel Lines
How do you know two lines are parallel?
Determine if any of the sets of lines are parallel. Justify your answer.
Line a passes through (-2, 4) and (3, 14).
Line b passes through (7, 2) and (-1, 3).
Line c passes through (3, 1) and (0, -5).
Line a: y= -13x+4
Line b: 3x-y=7
Line c: 6x + 2y = 12
Write the equation of the line parallel to x+4y = 6 that passes through the point (4, -8).

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.

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

Give the center and radius of the circle x2+y2=25
A) (2,3)r=5
B) (0,0)r=5
C) (0,0)r=25
D) (3,2)r=25
Answer:
B) (0,0); r=5
Step-by-step explanation:
A circle's standard form is (x-h)^2+(y-k)^2=r^2
The center is (h, k) and the radius is r.
So, here the center would be (0, 0) and the radius would be square root 25, or 5.
Answer:
(0,0) r=5

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.

27. G(t) = 70·0.72^t
G(3) = 26.127

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.
