Answer:
Perimeter = 30 + 4[tex]\pi[/tex] ≈42.56 cm
Area = 88 - 8[tex]\pi[/tex] ≈ 62.88 cm^2
Step-by-step explanation:
area of rectangle = 11* 8 = 88
Perimeter of rectangle = 38
perimeter of circle = 2[tex]\pi[/tex]4 = 8[tex]\pi \\[/tex]
area of circle = [tex]\pi 4^{2}[/tex] = 16 [tex]\pi[/tex]
Answer:
Step-by-step explanation:
Area of shaded region = Area of rectangle - area of semi circle
Rectangle:
length = 11 cm
Width = diameter of circle = 4 + 4 = 8 cm
Area 1 = length * width
= 11 * 8
= 88 sq. cm
Circle:
radius = r = 4 cm
Area of semicircle = [tex]\dfrac{1}{2}\pi r^{2}\\[/tex]
[tex]=\dfrac{1}{2}*3.14*4*4\\\\= 25.12 \ cm^{2}[/tex]
Circumference of semicircle = [tex]\dfrac{2\pi r}{2}=\pi r[/tex]
= 3.14 * 4
= 12.56 cm
Area of the shaded region = 88 - 25.12 = 62.88 = 63 square cm
Perimeter of shaded region = 11 + 8 + 11 + circumference of semicircle
= 11 + 8 + 11 + 12.56
= 42.56
= 43 cm

What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is given that:
The shapes are given in the picture.
From the definition of congruency; congruent figures are those that are exactly the same size and shape. Congruent is represented by the symbol ≅.
Form A has been translated into two units to the right and is congruent with shape D.
Form B is translated one unit to the left and congruent to shape E.
Thus, shape A is congruent to shape D and has been translated into 2 units to the right, and shape B is congruent to shape E and translated into 1 unit to the left.

The total length of the stage is 76 feet. An actor starts at point A then stops at point B before disappearing through the trap door. How far does he walk across the stage?
Answers
Answer:
since the distance from the outside edges is 26 1/2 feet, divide that by 2 to get the distance from the center to the edge ( 26 1/2 / 2 = 13 1/4 feet)
the stage is 76 feet so divide that by 2 to find the center 76/2 = 38 feet
now subtract the 13 1/4 from 38
38 - 13 1/4 = 24 3/4 feet from the side of the stage to the edge of the trap door
a little easier way would be to subtract the 26 1/2 from 76 and then divide by 2
76-26 1/2 = 49 1/2 / 2 = 24 3/4

Step-by-step explanation:
For Q1.
1. x + 5 = 8
x = 8 - 5
x = 3
2. -3x + 7 = 16
-3x = 16 - 7
-3x = 9
x = 9/-3
x = -3
3. 3P/7 = 6
3P = 6*7
3P = 42
P = 42/3
P = 14
4. 2(x + 5) = 24
2x + 10 = 24
2x = 24 - 10
x = 14/2
x = 7
5. x/5 - 8 = 9
x/5 = 9 - 8
x = 5
For Q.2:
1. 12 + 4(x + 3(x + 4)) = 108
12 + 4(x + 3x + 12) = 108
12 + 4x + 12x + 48 = 108
60 + 16x = 108
6x = 108 - 60
x = 48/6
x = 8
2. 5x + 7(4 - (x + 3)) = 31
5x + 28 - x + 3 = 31
6x + 31 = 31
6x = 0
x = 0
3. 2(3y - 2(y + 5) + 3) = -4

2y = 30
y = 15
4. 20 - 2(2x -(2 - x) + 10) = -44
20 - 2(2x - 2 + x + 10) = -44
20 - 2(3x + 8) = -44
20 - 6x - 16 = -44
4 - 6x = -44
-6x = -44 - 4
-6x = -48
x = -48/-6
x = 8
5. 5(3x - 4(x + 2) + 5(2x + 1)) = 60
5(3x - 4x - 8 + 10x + 5) = 60
5(3x - 4x + 10x - 8 + 5) = 60
5(9x - 3) = 60

kendra revived a bonus that was 30%of her monthly earnings is her monthly earnings were 930 how much was kendras bonus
Answers
Hey there! I'm happy to help!
30% is the same thing as 0.3 because 0.3 is 30% of 1. If you multiply something by 1, it will just stay the same, so you need that percent of 1.
To convert a decimal to a percent, you move the decimal to the left two spaces.
Now, we simply multiply this by 930.
0.3×930=279
So, Kendra will receive a bonus of $279.

Pythagoras for right-angled triangles :
c² = a² + b²
c is the Hypotenuse, the line opposite of the 90 degree angle.
a and b are the other 2 sides.
the distance between 2 points is the Hypotenuse of a right-angled triangle of the coordinate differences in x and y.
so, we have (-2, -3) and (3, 2)
distance² = (x1 - x2)² + (y1 - y2)² = (-2 - 3)² + (-3 - 2)² =
= (-5)² + (-5)² = 25 + 25 = 2×25 = 50
distance = sqrt(50) = sqrt(2×25) = 5×sqrt(2)

Rebecca bought a square rug for her office. If the area of the rug is 65ft estimate the side length of the rug to the nearest tenth.
Answers
Answer:16.3 ft
Step-by-step explanation:
The estimated value of the side length of the square rug is : 8.062 feets
Given that the area of the square rug = 65 ft²
Recall :
Area of a square = s²
Where, s = side length
Therefore,
Area of rug = s²
65 ft² = s²
65 = s²
Square both sides
√65 = s
8.062 = s
The estimated side length of the rug is 8.062 feets.

The ratio of boys to girls in a college marching band is 5:6. If there are 121 total students in this band, how many boys are in the band?
Answers
Answer:
Step-by-step explanation:
The ratio of boys to girls in the band is 5:6 and there are a total of 121 people.
We can call each bit of the ratio 'parts'.
So, there are a total of 5+6=11 parts in total, and there are a total of 121 people.
Therefore, each part of the ratio is equal to 121 ÷ 11 = 11.
Since there are 5 parts assigned to the number of boys in the band, then the total number of boys in the band is equal to 11 × 5, which is equal to 55 boys.
How would I get the answers to 9-14?
Answers
Answer:
9. 38
10. 19
11. 91
12. 89
13. 110
14. 109
Step-by-step explanation:
A line (PT) is always a total of 180 degrees and QVR = RVS (given) so let x = QVR then
PVQ + QVR + RVS + SVT = 180
72 + x + x + 70 = 180
72 + 2x + 70 = 180
2x = 180 - 72 - 70
2x = 180 - 142
2x = 38
x = 19
so
9. QVS = QVR + RVS = 2x = 19 + 19 = 38
10. QVR = x = 19
11. PVR = PVQ + QVR = 72 + 19 = 91
12. TVR = TVS + SVR = 70 + 19 = 89
13. PVS = PVQ + QVR + RVS = 72 + 19 + 19 = 110
14. TVQ = TVS + SVR + RVQ = 70 + 19 + 19 = 109
