Answer:
11.10 or 11.1 :)
Step-by-step explanation:
a² + b² = c²
6.5² + 9² = c²
42.25 + 81 = c²
42.25 + 81 = 123.25
123.25 = c²
√123.25 = c
√123.25 = 11.10 rounded :)
c= 11.10, if rounding to one decimal place, then 11.1 :)
On a coordinate grid, a trapezoid has vertices at (−6, 9), (−6, 6), (3, −9), and (3, 12). Each square on the grid represents 1 square foot. Explain how to find the area of the trapezoid.
Answer:
The area of the trapezoid is 108 square feet
Step-by-step explanation:
The given vertices of the trapezoid are;
(-6, 9), (-6, 6), (3, -9, and (3, 12)
Let the letters A, B, C, and D represent the vertices of the trapezoid, we have;
A(-6, 9), B(-6, 6), C(3, -9) and D(3, 12)
The drawing of the trapezoid on the coordinate plane created with MS Excel is attached
The area of a trapezoid, [tex]A_T[/tex] = (a + b)×h/2
Where;
'a', and 'b' = The length of the bases (parallel sides)
h = The height of the trapezoid (The distance between the bases)
Let 'a' represent the length of the long base CD and let 'b' represent the length of the short base AB
a = √((-9 - 12)² + (3 - 3)²) = 21
∴ a = 21 feet
Similarly, we have;
b = √((9 - 6)² + (-6 - (-6))² = 3
The height, h = The distance between AB and CD = AE
We note that sides AB and CD are parallel to the y-axis, therefore, the height which is the perpendicular distance to the between AB and CD will be parallel to the x-axis
Therefore, the t-coordinates of the points A and E are both equal to 9 and the length of AE = √((3 - (-6))² + (9 - 9)²) = 9
The height of the trapezoid, AE = 9 feet
∴ The area of the trapezoid, A = (21 + 3) × 9/2 = 108
The area of the trapezoid, [tex]A_T[/tex] = 108 ft.²

About how many feet of fencing are needed to go around the pool path? Use 3.14 for Pi. 88 ft 100 ft 176 ft 201 ft
Complete question :
A circular swimming pool has a radius of 28 ft. There is a path all around the pool that is 4 ft wide. A fence is going to be built around the outside edge of the pool path.
About how many feet of fencing are needed to go around the pool path
Answer:
201 feets
Step-by-step explanation:
The Circumference of a circle, C :
C = 2 * pi * r
r = Radius ; pi = 3.14
The entire Radius = pool radius + pathnaroind the pool = 28 + 4 = 32
Hence, the Circumference, which gives the value of fencing required is :
C = 2 * 3.14 * 32
C = 200.96 ft
C = 201 feets

What are trigonometric relations?
Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the triangle be represented as CDE
Now , the length of the side CE = 19m
The measure of the angle ∠DCE = 64°
So , the length of the side CD is given by the trigonometric relations is
cos θ = adjacent / hypotenuse
Substituting the values in the equation , we get
cos 64° = x/19
Multiply by 19 on both sides of the equation , we get
x = 19 x cos 64°
On simplifying the equation , we get
x = 19 x 0.4384
x = 8.3296 m
x = 8.3 m
Therefore , the value of x is 8.3 m
Hence , the length of the side CD is 8.3 m

"ATTICUS_SWEETLOVER"A stack of one dozen cookies of diameter 5 in. exactly fits in a cylindrical container of volume
176.715 in.^3 . What is the thickness of each cookie?
Answer:
The thickness of each cookie is 9.00 inches.
Step-by-step explanation:
The volume of the cookies is given by the volume of a cylinder:
[tex] V = \pi r^{2}h [/tex] (1)
Where:
V: is the volume = 176.715 in³
r: is the radius
h: is the height = thickness of the cookies
The radius can be calculated by dividing the diameter by 2:
[tex] r = \frac{d}{2} = \frac{5}{2} = 2.5 in [/tex]
Now, by solving equation (1) for "h" we have:
[tex] h = \frac{V}{\pi r^{2}} = \frac{176.715}{\pi (2.5)^{2}} = 9.00 in [/tex]
Therefore, the thickness of each cookie is 9.00 inches.

A helicopter flies from the airport on a course with a bearing of 21 degrees. After flying for 99 miles, the helicopter flies due east for some time. The helicopter flies back to the airport with a bearing of 227 degrees. How far did the helicopter fly on the final leg of its journey?
Answer:
Step-by-step explanation:
From the question we are told that:
Initial bearing [tex]\angle _1=21 \textdegree[/tex]
Initial distance [tex]d_1=99miles[/tex]
Final bearing [tex]\angle _2=227 \textdegree[/tex]
Let [tex]\triangle OAB[/tex] be the perimeter travailed
[tex]\angle OAB=90+21=111 \textdegree\\\angle ABO=270-227=43 \textdegree[/tex]
Generally the equation for OB using sine rule is mathematically given by
[tex]OB=99*\frac{sin111}{sin43}[/tex]
[tex]OB=135.52miles[/tex]
Therefore the helicopter flight on the final leg of its journey is
[tex]OB=135.52miles[/tex]
