The members of the gardening group plan to build a walkway through the garden as formed by the hypotenuse of each of the four triangles in the drawing. That way, the gardeners will be able to access all sections of the garden. Calculate the length of the entire walkway to the nearest hundredth of a yard. Show your work. (4 points—1 point for each length calculation and 1 point for the total distance)
Is the value you just wrote for the total length of the walkway a rational or irrational number? Explain. (2 points)
Answers
Answer:
1) The length of the entire walkway to the nearest hundredth of a yard is 50.24 yds
2) 50.24 is a rational number
Step-by-step explanation:
1) To calculate the length of the walkway, you need to find "b"
the value of b using the Pythagoras theorem can be written as,
D²=12²+b²
15²=12²+b²
225=144+b²
b²=81
b=9
the value of each of the four hypotenuses can be written as,
A = [tex]\sqrt{12^2+8^2}[/tex] = [tex]\sqrt{208}[/tex] = 14.422
B = [tex]\sqrt{6^{2} +8^{2} }[/tex] = [tex]\sqrt{100}[/tex] = 10
C = [tex]\sqrt{6^2+9^2}[/tex] = [tex]\sqrt{117}[/tex] = 10.82
D = 15
Adding the value of all the hypotenuse to get the length of the walkway, therefore, the length will be,
14.422 + 10 + 10.82 + 15 = 50.24
So, the entire walkway to the nearest hundredth is 50.24
2) Because Irrational numbers are ones that never end.
50.24 is a nice, round number, even though its a decimal.
Answer:
50.24 - rational number

What is the area and circumference of the circle (3.14 for pi)
Answers
We will use the proper formula and solve.
-> A diameter of 48 / 2 = 24 feet as our radius
Area:
A = πr²
A = (3.14)(24)²
A = 1,808.64 ft²
The circle has an area of about 1,808.64 ft²
Circumference:
C = 2πr
C = 2(3.14)(24)
C = 150.72 ft
The circle has a circumference of about 150.72 ft
Answer:
Circumference = 150.72
Area = 1808.64

What is the interquartile range of this data set?
{18, 17, 10, 25, 20, 20, 30, 18, 18, 30, 25}
Enter the answer in the box.
Answers
The interquartile range of the data set is 7.
Step-by-step explanation:
The given set of data is {18 , 17 , 10 , 25 , 20 , 20 , 30 , 18 , 18 , 30 , 25}
Arrange the data in ascending order:
10 , 17 , 18 , 18 , 18 , 20 , 20 , 25 , 25 , 30 , 30
Divide the data in two equal parts:
(10 , 17 , 18 , 18 , 18), 20 ,(20 , 25 , 25 , 30 , 30)
Divide each parenthesis in 2 equal parts:
(10 , 17), 18 ,(18 , 18), 20 ,(20 , 25), 25 ,(30 , 30)
Now we can say that,
Q₁ = 18 , Median = 20 , Q3 = 25
Interquartile rage of a data is :
I.Q.R. = Q3 - Q1
I.Q.R. = 25-18 = 7
Therefore the interquartile range of the data set is 7.
