Find the area of the composite figure.
Answer:
The Area of the composite figure would be 76.26 in^2
Step-by-step explanation:
According to the Figure Given:
Total Horizontal Distance = 14 in
Length = 6 in
To Find :
The Area of the composite figure
Solution:
Firstly we need to find the area of Rectangular part.
So We know that,
[tex]\boxed{ \rm \: Area \: of \: Rectangle = Length×Breadth}[/tex]
Here, Length is 6 in but the breadth is unknown.
To Find out the breadth, we’ll use this formula:
[tex] \boxed{\rm \: Breadth = total \: distance - Radius}[/tex]
According to the Figure, we can see one side of a rectangle and radius of the circle are common, hence,
[tex] \longrightarrow\rm \: Length \: of \: the \: circle = Radius[/tex]
Since Length = 6 in ;[tex]\longrightarrow \rm \: 6 \: in = radius[/tex]
Hence Radius is 6 in.
So Substitute the value of Total distance and Radius:
Total Horizontal Distance= 14 Radius = 6[tex] \longrightarrow\rm \: Breadth = 14-6[/tex]
[tex] \longrightarrow\rm \: Breadth = 8 \: in[/tex]
Hence, the Breadth is 8 in.
Then, Substitute the values of Length and Breadth in the formula of Rectangle :
Length = 6Breadth = 8[tex] \longrightarrow\rm \: Area \: of \: Rectangle = 6 \times 8[/tex]
[tex]\longrightarrow \rm \: Area \: of \: Rectangle = 48 \: in {}^{2} [/tex]
Then, We need to find the area of Quarter circle :
We know that,
[tex]\boxed{\rm Area_{(Quarter \; Circle) } = \cfrac{\pi{r} {}^{2} }{4}} [/tex]
Now Substitute their values:
r = radius = 6 π = 3.14[tex]\longrightarrow\rm Area_{(Quarter \; Circle) } = \cfrac{3.14 \times 6 {}^{2} }{4} [/tex]
Solve it.
[tex]\longrightarrow\rm Area_{(Quarter \; Circle) } = \cfrac{3.14 \times 36}{4} [/tex]
[tex]\longrightarrow\rm Area_{(Quarter \; Circle) } = \cfrac{3.14 \times \cancel{{36} } \: ^{9} }{ \cancel4} [/tex]
[tex]\longrightarrow\rm Area_{(Quarter \; Circle)} =3.14 \times 9[/tex]
[tex]\longrightarrow\rm Area_{(Quarter \; Circle) } = 28.26 \: {in}^{2} [/tex]
Now we can Find out the total Area of composite figure:
We know that,
[tex]\boxed{ \rm \: Area_{(Composite Figure)} =Area_{(rectangle)}+ Area_{ (Quarter Circle)}}[/tex]
So Substitute their values:
[tex]\rm Area_{(rectangle)}[/tex] = 48 [tex]\rm Area_{(Quarter Circle)}[/tex] = 28.26[tex]\longrightarrow \rm \: Area_{(Composite Figure)} =48 + 28 .26[/tex]
Solve it.
[tex]\longrightarrow \rm \: Area_{(Composite Figure)} =\boxed{\tt 76.26 \:\rm in {}^{2}} [/tex]
Hence, the area of the composite figure would be 76.26 in² or 76.26 sq. in.

Of 250 seventh grade students, 130 walk to school. What percent of seventh graders do not walk to school? % of seventh graders do not walk to school.
Answer:
48%
Step-by-step explanation:
I like to look at percentages as test grades. If you got a 130/250 on a test, you would simply need to view the dash line as a 'divided by'. So you would figure 130 divided by 250 is .52, or 52%... Then, you would need to subtract 52 from 100 to get 48% to get the percentage of people who do not walk to school.
48%
48% of 250 is 120
120+130=250

What is Pythagoras theorem?The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagorean theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
The length of the laser beams is the addition of the segments AD to segment CB (which are equal).
Using Pythagoras theorem in ECD
ED² = EC² + CD²
ED= √(12² + 35²)
ED = √144 + 1225
ED = 37 unit
Again In Triangle AED
AD² = EA² + ED²
AD=√15² + 37²
AD = 40 unit
Then, there are total of 80 ft of laser beams.

An airplane flies into the wind for 5 hours, traveling 900 miles. The airplane then
turns around and flies with the wind, returning to its starting place in 4 hours.
This can be modeled by the following system of equations, where (s) is the speed
of the plane with no wind and (w) is the speed of the wind.
5(s-w)=900
4(s+w) = 900
What is the speed of the wind in miles per hour?
Answer:
22.5 miles per hour
Step-by-step explanation:
Given system of equations
5(s-w)=900
4(s+w)=900
Set equations equal to each other
5(s-w)=4(s+w)
5s-5w=4s+4w
s-5w=4w
s=9w
Solve for w using the substitution s=9w
4(s+w)=900
4(9w+w)=900
4(10w)=900
40w=900
w=22.5
Therefore, the speed of the wind is 22.5 miles per hour

Rebecca Hut a circular cake into six slices of equal size each cake slice has an area of 13 in.² what is the radius of Rebecca‘s cake to the nearest whole inch
The cakes radius is ______ inches
Answer:
5 inches
Step-by-step explanation:
Area of the cake:
1 slice = 13 in²6 slices = 13 in² * 6 = 78 in²Area circle: πr²
Solve for r:
78 = πr²r² ≈ 24.84 r ≈ 5-Chetan K
Answer:
The cakes radius is 5 inches.
Explanation:
cake has a circular area. Therefore we will use, area of circle: πr²Here given the cake is cut in six equal size.The area of the slice will be [tex]\frac{1}{6}[/tex](πr²)Steps:
→ [tex]\frac{1}{6}[/tex]πr² = 13
→ πr² = 13(6)
→ πr² = 78
→ r² = [tex]\frac{78}{\pi }[/tex]
→ r = [tex]\sqrt{\frac{78}{\pi }}[/tex]
→ r = 4.982787485
→ r = 5
Therefore the cake has a radius of 5 inches. Do not misunderstand that we are taking slice radius, its the radius of the cake all along.
An artist designs a sculpture in the shape of a rectangular prism.
The sculpture has a width of x feet. The depth of the sculpture is 6 feet more than the width. The length of the sculpture is 12 feet less than twice the width.
Given the sculpture's volume in cubic feet is 26 times its width in linear feet, what is the length of the sculpture?
Answer: 2
Step-by-step explanation:
took the quiz
The length of the sculpture is 2 feet.
Given information about the sculpture:
Width of the sculpture = x feet
Depth of the sculpture = x + 6 feet
Length of the sculpture = 2x - 12 feet
The volume of a rectangular prism is given by the formula:
Volume = length × width × depth
According to the given information, the volume of the sculpture is 26 times its width in linear feet. Therefore, write the equation as:
Volume = 26 × Width
Volume = 26x
Write the expression for the volume of the sculpture using the dimensions:
Volume = (2x - 12) × x × (x + 6)
Set up the equation:
26x = (2x - 12) × x × (x + 6)
26x = (2x² - 12x) × (x + 6)
26x = 2x³ + 12x² - 12x² - 72x
26x = 2x³ - 72x
Now, rearrange the equation to set it equal to zero:
2x³ - 72x - 26x = 0
2x³ - 98x = 0
2x(x² - 49) = 0
2x = 0
x = 0
And, the value of x is calculated as:
x² - 49 = 0
x² = 49
x = ±√49
x = ±7
Since dealing with dimensions, have a negative value for x.
Therefore, x = 7.
The value of x is 7, find the length of the sculpture:
Length = 2x - 12
Length = 2 × 7 - 12
Length = 14 - 12
Length = 2 feet
So, the length of the sculpture is 2 feet.

Bill's chocolate bar is 69% cocoa. If the weight of the chocolate bar is 83 grams, how many grams of cocoa does it contain? Round your answer to the nearest tenth.
Answer:
Bill's bar has 57.3 grams of cocoa.
Step-by-step explanation:
The math part that your question is asking is: What is 69% of 83?
In order to use the percent 69% in a calculation, you need to change it to a decimal.
69% is 0.69
You move the decimal to the left, two places.
69% is 69.% If you don't see a decimal to start with and it is a whole number, then the decimal is starting on the right.
Move it two places to the left, you get
.69
Now MULTIPLY.
.69 × 83
= 57.27
ROUND your answer to the nearest tenth. That means only one digit to the right of the decimal.
57.27 rounds to 57.3
