Answer:
The height of the hot air balloon is 1514.54 feet approximately.
Step-by-step explanation:
Consider the provided information.
The angle of elevation from the top of a 95-foot tall building to a hot air balloon in the sky is 76. If the horizontal distance between the building and the hot air balloon is 354 feet, find the height of the hot air balloon
The figure is shown below:
Let the height of the balloon is AD, the height of the building is BC.
Draw a line BE parallel to CD.
Therefore, AD=x+95, BC=95 and BE=CD=354 ft
Now in triangle [tex]ABE[/tex].
[tex]\tan\theta=\dfrac{\text{Opp}}{\text{Adj}}[/tex]
[tex]\tan76^{\circ}=\dfrac{AE}{BE}[/tex]
[tex]AE\approx 4.01\times 354[/tex]
[tex]AE\approx 1419.54[/tex]
The height air balloon is 1419.54+95 =1514.54 ft
Hence, the height of the hot air balloon is 1514.54 feet approximately.

Population density is the number of people per unit of area. The population density of a certain region is 50 people per square kilometer. If the region covers 25 square kilometers, what is the population of the region?
Answer:
1250 people
Step-by-step explanation:
Population density = total population / land area
Population density = 50
total population = x
land area 25
50 = x / 25
x = total population = 50 x 25 = 1250 people
what expression is equivalent to h + 5 + 3 - 2h
The equivalent expression of h + 5 + 3 - 2h is -h+8.
What are the equivalent expressions?Expressions that are equivalent to the same thing, even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).
We have the expression:
h + 5 + 3 - 2h
To find the equivalent expression:
We simplify the expression,
h + 5 + 3 - 2h
= h -2h +5+ 3
= -h +8
-h+8 is the equivalent expression of h + 5 + 3 - 2h.
Therefore, -h +8 is the equivalent expression.

Colin invests £1100 into his bank account. He receives 5% per year simple interest. How much will Colin have after 6 years?
Answer:
£1430
Step-by-step explanation:
Given data
Principal =£1100
Rate= 5%
time = 6 years
The simple interest formula is
A=P(1+rt)
substitute
A=1100(1+0.05*6)
A=1100(1+0.3)
A=1100(1.3)
A=1100*1.3
A=£1430
Hence the balance is £1430

Answer:
112º
Step-by-step explanation:
(you may need a calculator for this)
first let's start with what we know, we know a triangle has 180º. We also know a line has 180º. if you know the line has 180º, then ? + 126 º = 180º. so if you subtract 126 from 180, you get 54. now lets look at the triangle, we know the triangle has 180º in total. we already know one angle is 58º, and we just figured out the other is 54º. if you do 54+58, you get 112. remember, the triangle has 180 degrees in total, and two of them equal 112º, so 180 - 112 is 68. almost there! now we have to do the line trick again, because on the line, 68 + x = 180. 180- 68 is 112, so the answer is 112º. Hope this helps :D

Step-by-step explanation:
Summer (starting from rest) runs from the 20 m mark to the 35 m mark with an acceleration of .5 m/s2. What is her final velocity?
If Summer (starting from rest) runs from the 20 m mark to the 35 m mark with an acceleration of 5 m/s². then 12.25 m/s is the final velocity.
What is Velocity?Velocity is the distance covered by an object in unit time.
Given that,
Summer (starting from rest) runs from the 20 m mark to the 35 m mark with an acceleration of 5 m/s²
a=0.5 m/s²
s is distance=35-20=15
We have a formula with velocity, acceleration and distance
Now v²=2as
Here v is velocity=2
a is acceleration=5
s is the distance.=15
v²=2×5×15
The multiplication value of 2×5×15 is 150.
v²=150
Take square root on both sides
v=√150
v=12.25 m/s
Therefore final velocity is 12.25m/s.

. A flagpole is standing in front of City Hall. Percy, who is standing near the flagpole is 5' tall and casts a shadow 3' long. If the flagpole casts a shadow 36' long, how tall is the flagpole
Answer:
The flagpole is 60'(60 inches) tall
Step-by-step explanation:
A flagpole is standing in front of City Hall. Percy, who is standing near the flagpole is 5' tall and casts a shadow 3' long. If the flagpole casts a shadow 36' long, how tall is the flagpole
The formula is given as:
Height of percy/ Shadow of percy = Height of flagpole/Shadow of flagpole
Height of percy = 5 inches
Shadow of percy = 3 inches
Height of flagpole = ??
Shadow of flagpole =36 inches
= 5/3 = x/36
Cross Multiply
3 × x = 36 × 5
3x = 36 × 5
x = 36 × 5/3
x = 60 inches
Therefore, the flagpole is 60'(60 inches) tall.

What is the parabola?It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.
The general equation is given below.
y = ax²
If the value of a is negative then downward parabola and if the value of a is positive then upward parabola.
If the value of a is less than one then parabola shrinks and if the value of a is more than one then parabola spreads.
Graph A is upward and shrinks parabolas so the equation will be y = x⁸.
Graph B is downward parabolas so the equation will be y = -3x⁸.
Graph C is upward and wider parabolas so the equation will be y = 0.25x⁸.
Then the correct matching will be given as A-1, B-3, and C-2.
