How can you decompose the composite figure to determine its area? as three triangles and a circle as two triangles, a rectangle, and a circle as a triangle, a pentagon, and a semicircle as a triangle, a rectangle, and a semicircle
We can decompose the composite figure into a triangle, a rectangle, and a semicircle in order to find the area of the composite figure.
What is the area?The space filled by a flat form or the surface of an item is known as the area.
The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.
The area of the composite figure is equal to the sum of area 1, area 2, and area 3
Area 1 - triangle
Area 2 - rectangle
Area 3 - semicircle
We can decompose the composite figure into a triangle, a rectangle, and a semicircle in order to find the area of the composite figure.
Hence option d is correct.

No, They are complementary
Step-by-step explanation:
Supplementary is when the angles add up to 180 degrees.
Complementary is when the angles add up to 90 degrees.
Answer:
No it isn’t a supplementary angle because supplementary angles add up to 180 degrees. 81+9=90

74. The mean of 50 test scores was calculated as 88.
But, it turned out that one of the scores was
misread at 94 but it was 69. What is the mean?
85
87
87.5
88.5
The mean if the scores was misread at 94 but it was 69 is 87.5
How to find the mean of a number?Mean is also known as average. It is mathematically represented as:
Mean = Sum of data/Sample space
Given the following parameters
Mean = 88
Sample size = 50
Substitute
88 = Sum/50
Sum = 88(50)
Sum = 4400
If one of the scores was misread at 94 but it was 69, hence;
Sum + (94-69) = 4400
Sum + 25 = 4400
Sum = 4400 - 25
Sum = 4331
New mean = 4375/50
New mean = 87.5
Hence the mean if the scores was misread at 94 but it was 69 is 87.5

The error is in step 2 in step 2 Susu forgot to divide 8 by 4 for finding the solution of a quadratic equation.
What is a quadratic equation?The name Quadratic comes from "quad" meaning square, because the variable gets squared (like x2). It is also called an "Equation of Degree 2"
Susu is solving the quadratic equation [tex]4x^2-8x-13=0[/tex] by completing the square
To apply to completing the square method we need to get x^2 alone
Susu added 13 on both sides. So step 1 is correct
When we factor out 4, we divide both terms by 4
[tex]4(\dfrac{4x^2}{4}-\dfrac{8x}{2})=13[/tex]
[tex]4(x^2-2x)=13[/tex]
Susu forgot to divide 8 by 4

In the given circle with the centre O,
angle ABC = 100° angleACD = 40° and CT is a tangent to the circle at C. Find Angle ADC and Angle DCT.
Step-by-step explanation:
As the points A, B, C and D lie on a circle, So, ABCD is a cyclic quadrilateral...
As, Sum of opp. ∠s in a cyclic quadrilateral = 180°
∴ ∠ADC + ∠ABC = 180°
=> ∠ADC + 100° = 180° => ∠ADC = 80°
Now,
Sum, of all angles in a traingle = 180°
In ΔACD, ∠CAD + ∠ADC + ∠ACD = 180°
=> ∠CAD + 80° + 40° = 180°
=> ∠CAD = 180° - 80° - 40° = 60°
As CT is tangent to the circle at the point C and CD is a chord of the circle, So
∠DCT = ∠CAD........(∠s in alternate segments are equal,,So ∠CAD = 60°)
=> ∠DCT = 60°
Hope it helps you!!Answer:
See below ~
Step-by-step explanation:
∠ADC
∠ABC + ∠ADC = 180° (Angles in a cyclic quadrilateral)∠ADC = 180° - 100° = 80°∠DCT
∠DCT = ∠CAD (ANGLES IN ALTERNATE SEGMENTS EQUAL)∠CAD = 180° - 80° - 40° = 60°∠DCT = 60°HELP NO HURRY TAKE YO TIME FOR MY SISTERRR

A 40-pound case of bananas costs $23.60. How much would a 70-pound case cost?
Answer:
$41.30
Step-by-step explanation:
First, divide 23.60 by 40
23.60/40 = 0.59
0.59 is the unit price, (or the worth of one {1} pound case)
0.59 * 70 = 41.3
$41.30 is the cost of a 70-pound case of bananas

Find the perimeter of each figure in feet, 48 in 3yd 5ft 1yd .
Answer:
Step-by-step explanation:
Remark
First of all, all the units must be the same. Inches is probably the best unit to use.
Second the base line at the bottom must be completed. How long is it
Givens
Left side = 48 inches
Top = 3 yards
1 yard is 36 inches.3 yard is 3* 36 = 108 inches.Right side = 5 feet.
1 foot = 12 inches5 feet = 12 * 5 = 60 inchesBottom = 1 yard + top
Bottom = 1 yard + 3 yards
Bottom = 4 yards
1 yard = 36 inches4 yards = 144 inchesPerimeter = 144 + 60 + 108 + 48
Perimeter = 360 Inches.
Answer
Perimeter = 360 inches
Perimeter = 360 / 12 = 30 feet There are 12 inches in a foot
Perimeter = 360 / 36 = 10 yards. There are 36 inches in a yard
The question does not specify the units. Probably inches would work, but if a computer is marking your answer and you get it wrong, you are going to have to try the other two answers in turn.
