A balloon rises vertically from point p on level ground. From point a, on level ground 28ft from point p, the angle of elevation to the balloon is 79\deg . How high is the balloon?
Answer: Balloon is 27.5 ft high.
Step-by-step explanation:
As per the give , we made a diagram (in attachment).
To find the vertical distance from the growth we consider entire triangle as right triangle , where height is making right angle with ground.
in right triangle,
[tex]\sin \theta=\dfrac{Hypoteuse}{height}\\\\\Rightarrow\ \sin 79^{\circ}=\dfrac{28}{height}\\\\\Rightarrow\ 0.98162718344=\dfrac{28}{height}\\\\\Rightarrow\ height = 0.98162718344\times28\\\\\Rightarrow\ height = 0.98162718344\times28\approx27.5[/tex]
hence, balloon is 27.5 ft high.
On the Guardian lines a and B
Answer:
2 and - 1
Step-by-step explanation:
Calculate the gradients using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, -3) and (x₂, y₂ ) = (3, 7) ← 2 points on line A
[tex]m_{A}[/tex] = [tex]\frac{7+3}{3+2}[/tex] = [tex]\frac{10}{5}[/tex] = 2
with (x₁, y₁ ) = (- 2, 7) and (x₂, y₂ ) = (7, - 2) ← 2 points on line B
[tex]m_{B}[/tex] = [tex]\frac{-2-7}{7+2}[/tex] = [tex]\frac{-9}{9}[/tex] = - 1

At the end of a snow storm, Allison saw there was a lot of snow on her front lawn. The temperature increased and the snow began to melt at a steady rate. There was a depth of 20 inches of snow on the lawn when the storm ended and then it started melting at a rate of 1.25 inches per hour. Write an equation for S , S, in terms of t , t, representing the depth of snow on Allison's lawn, in inches, t t hours after the snow stopped falling.
Answer:
S=20-1.25t
Step-by-step explanation:
I got this answer welcome.
The equation for depth of snow after t hours is, S = 20 - 1.25 t.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
The initial depth of snow = 20 inches,
Rate of melting = 1.25 inches per hour.
After t hours, the snow melt = 1.25 t
The equation of the S in terms of t can be written as,
S= 20 - 1.25 t.
The required equation is S = 20 - 1.25 t.

An independent study commissioned by the stadium showed that running a cable TV ad 5 times daily for a week generated 1,200 ticket sales. The stadium wants to sell out an upcoming show, which requires the sale of 13,200 tickets. How long should the stadium run the cable ad in order to reach this target?
Answer
I think 55 times
Step-by-step explanation:
13,200/1,200 = 11
5/1200 = x/13,200
so if 1,200*11=13, 200 then 5*11= 55.
btw , could u give me the brainliest if i am right?
The total time the stadium runs the cable ad in order to reach this target is 11 days and this can be determined by using the unitary method.
Given :
Running a cable TV ad 5 times daily for a week generated 1,200 ticket sales. The stadium wants to sell out an upcoming show, which requires the sale of 13,200 tickets.The following steps can be used in order to determine the total times the stadium run the cable ad in order to reach this target:
Step 1 - The unitary method can be used in order to determine the total times the stadium runs the cable ad in order to reach this target.
Step 2 - According to the given data, running a cable TV ad 5 times daily for a week generated 1,200 ticket sales.
Step 3 - If running TV ad 5 times daily sales 1200 tickets then to sell 13200 tickets the total times the ad is running is:
[tex]=\dfrac{13200}{1200}\times 5[/tex]
= 55 times
Step 4 - Now, if 5 times ad running in one day then 55 times ad running in:
[tex]=\dfrac{55}{5}\times 1[/tex]
= 11 days

Answer:
[tex]\frac{4}{5}[/tex]
Step-by-step explanation:
A fraction is in simplest form when no other factor but 1 will divide into the numerator/ denominator
[tex]\frac{5}{10}[/tex] ← divide numerator/ denominator by 5
=[tex]\frac{1}{2}[/tex]
[tex]\frac{4}{5}[/tex] ← is in simplest form
[tex]\frac{6}{10}[/tex] ← divide numerator/denominator by 2
= [tex]\frac{3}{5}[/tex]
[tex]\frac{8}{12}[/tex] ← divide numerator/denominator by 4
= [tex]\frac{2}{3}[/tex]
[tex]\frac{4}{5}[/tex] is the only fraction given in simplest form
Line m contains the points (−3, 2) and (5 , 1). Line n contains the points (2 , 7) and (1, −1) . Which statement is TRUE about lines m and n?
A. The lines are parallel.
B. The lines are coincident.
C. Both lines intersect but are neither parallel nor perpendicular.
D. The lines are perpendicular.
9514 1404 393
Answer:
D. The lines are perpendicular
Step-by-step explanation:
The first line has a rise of (1-2) = -1 for a run of (5-(-3)) = 8.
The second line has a rise of (-1-7) = -8 for a run of (1-2) = -1.
Then the slopes are -1/8 and -8/-1 = 8, which are negative reciprocals of each other. Lines with slopes having that relationship are perpendicular.

What is proportion?The ratio of two numbers a and b is given by a divided by b and represented by a/b or a:b. While the proportion is the relation between two ratios of a/b and c/d is represented by a:b::c:d or a/b=c/d.
Given that, there are 8 big fish for every 10 small fish, we need to find how many are there for 4 big fish for every.
We will solve this by using proportion,
Let the number of small fishes be x
Therefore,
8 / 10 = 4 / x
x = 5
Hence, there are 5 small fish for every 4 big fishes.

The only triangle with the base being bisected perpendicularly is an isosceles triangle or an equilateral triangle. Therefore, [tex]KJ = KL[/tex]
[tex]KJ = 4x + 9\\KL = 11x - 61\\[/tex]
Since the sides are equal, we can equate the expressions to get the equation:
[tex]4x + 9 = 11x - 61\\11x - 4x = 70\\x = 10[/tex]
[tex]x[/tex] is equal to [tex]10[/tex].
Plug that in [tex]11x - 61[/tex] and you get [tex]110 - 61[/tex] which is [tex]49[/tex]. So, Option B is correct :D
