Ava is in a hot air balloon that has just taken off and is floating above its launching point. Mary is standing on the ground 4 meter away from the launching point. If ava and mary are 5 meters apart, how high up is ava ?
Answer:
Ava's altitude is 3 meters.
Step-by-step explanation:
The position of Ava and Mary can be described by the sides of a right angled triangle. Let Ava's altitude be represented by x.
So that applying the Pythagoras theorem, we have;
[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]5^{2}[/tex] = [tex]4^{2}[/tex] + [tex]x^{2}[/tex]
25 = 16 + [tex]x^{2}[/tex]
[tex]x^{2}[/tex] = 25 - 16
= 9
x = [tex]\sqrt{9}[/tex]
= 3
x = 3 meters
Thus, Ava's altitude is 3 meters.

Hey mate.....
Step-by-step explanation:
This is ur answer.....
Measure angle 2 = 125M.A 1 = 180 - 125 ( Supplementary angle)
M.A 1 = 55
M.A 3 = 125 (Vertically Opposite Angles)
M.A 4 = 55 (Vertically Opposite Angles)
M.A 5 = 55 ( Corresponding Angle)
M.A 6 = 125 ( Corresponding Angle)
M.A 7 = 125 ( Vertically Opposite Angle)
M.A 8 = 55 ( Vertically Opposite Angle)
Hope it helps!

Answer:
∠1 = 55°
∠3 = 125°
∠4 = 55°
∠5 = 55°
∠6 = 125°
∠7 = 125°
∠8 = 55°
Step-by-step explanation:
This is the detective case for vertical angles!!(dun-dun-dun!!!!)
Ok the info we have is that Angle 2 is 125°
Ok, quick, take ten seconds, the other group might take the victory coin. What is the vertical angle for angle 2?
-----
3! Correct
3 is the vertical angle because it is one part of the pair of opposite angles made by two intersecting lines.
3 is now 125°
The sum of all angles 1,2,3,4 is 360°
360° - 125° - 125° = 110°
110° / 2 (because 1 and 4 are vertical, they are equal) = 55°
1 = 55° and 4 = 55°
Lets do this for 5,6,7, and 8
Angle 1 = angle 5 because it is the law of same side interior(corresponding) angles, or they are the same because the lines are parallel to each other.
So angle 5= 55°
then angle 8 = 55°
6 = 125° and 7 = 125°
Yay you beat the other team. Great job you win a victory coin(which basically is something that is absolutely nothing)
Determine the surface area from the folllowing nets. Type the answer in the space provided (no units needed). If the answer is correct a mystery picture will appear. (Zo om in for bigger picture of dimensions)
Answer:
1.) 138
2.) 55
Step-by-step explanation:
1.) 8 x 6 = 48 x 2 = 96
(middle) 8 x 3 = 24
(triangles) 6 x 3 = 18 divided by 2 = 9 x 2 = 18
96 + 24 + 18 = 138
2.) (middle) 5 x 5 = 25
(triangles) 5 x 3 = 15 divided by 2 = 7.5 x 4 = 30
30 + 25 = 55

A sandbox in the shape of a trapezoid is show below. If a cover is to be made for the sandbox, what if the minimum amount of fabric needed?
The minimum amount of fabric needed for a sandbox is,
⇒ 72 feet²
We have to given that;
A sandbox in the shape of a trapezoid is show below.
And, a cover is to be made for the sandbox.
Hence,
The minimum amount of fabric needed for a sandbox is,
⇒ Area of fabric = 9 × 7 + (1/2 × 9 × 2)
= 63 + 9
= 72 feet²
Thus, The minimum amount of fabric needed for a sandbox is,
⇒ 72 feet²

[tex](10x + 9 {)}^{2} [/tex]
Step-by-step explanation:
1) Rewrite it in the form a² + 2ab + b², where a = 10x and b = 9.
[tex](10x) ^{2} + 2(10x)(9) + {9}^{2} [/tex]
2) Use square sum: ( a + b )² = a² + 2ab + b².
[tex](10x + 9 {)}^{2} [/tex]
Hence, the answer is (10x + 9)².

An advertising flyer shows address labels as 4.3 cm by 1.2 cm. The ratio of the flyer label to the actual label is 2:3. What are the dimensions of the actual address labels?
Answer:
6.45 cm by 1.8 cm
Step-by-step explanation:
Ratio of label to actual measurement ; 2 : 3
For a flyer label size of 4.3
Actual label size equals :
(Flyer ratio / total ratio) * total size = flyer size
2/5 * x = 4.3
2x / 5 = 4.3
2x = 21.5
x = 21.5 / 2
x = 10.75
Actual size =. 10.75 - 4.3 = 6.45 cm
2/5 * x = 1.2
2x / 5 = 1.2
2x = 6
x = 6 / 2
x = 3
Actual size = 3 - 1.2 = 1.8 cm
6.45 cm by 1.8 cm

Betty wants to put new cabinets in her kitchen. She measures one side of her kitchen and finds it measures 18 meters. Which measurement did Betty find?
Answer:
A. Length
Step-by-step explanation:
Betty wants to put new cabinets in her kitchen. She measures one side of her kitchen and finds it measures 18 meters.
Which measurement did Betty find?
A. Length
B. Perimeter
C. Area
The measurements Betty found is the length of the cabinet
A side of the cabinet is equivalent to the length of such cabinet
To find the perimeter of the cabinet, it requires the addition of all the sides of the cabinet.
To find the area of the cabinet, it requires the multiplication of two different sides of the cabinet.
Therefore, Betty has only measured the length of the cabinet

Answer:
Burgers - $8.29 and fries - $4.39Step-by-step explanation:
Let burgers - b, fries - f
8b + 3f = 79.4912b + 6f = 125.82Double the first equation and subtract the second equation:
16b + 6f - 12b - 6f = 2(79.49) - 125.824b = 33.16b = 33.16/4b = 8.29Find f:

Answer:
a = 4
Step-by-step explanation:
a² = 5² - 3²
a² = 25 - 9 = 16
√16 = 4
a = 4
Answer:
a = 4
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 3² = 5²
a² + 9 = 25 ( subtract 9 from both sides )
a² = 16 ( take the square root of both sides )
a = [tex]\sqrt{16}[/tex] = 4
