The shadow of a vertical tower is 52.5 meters long when the angle of elevation of the sun is x degrees. The height of the tower is 41 meters. Find the angle of elevation rounded to the nearest degree.
Answer:
Angle of Elevation = 38°
Step-by-step explanation:
Angle of Elevation formula is given as
tan x = Opposite /Adjacent
Where
x = Angle of Elevation
Opposite = Height of the tower = 41 meters
Adjacent = Shadow of the vertical tower = 52.5 meters
Hence:
tan x = 41 m/52.5m
x = arc tan (41 m/52.5m)
x = 37.988141726°
Approximately to the nearest degree x = 38°

To the nearest hundredth, which is the value of x in the solution of the following system? 3.5x - 2.8 = -4.67x + 12.5 Select one: a. -3.75 b. -1.87 c. 1.87 d. 3.75
Answer:
C. 1.87
Step-by-step explanation:
3.5x - 2.8 = -4.67x + 12.5
3.5x + 4.67x = 12.5 + 2.5
8.17x = 15.3
x = 15.3 ÷ 8.17
x = 1.87270501836
So, the closest choice to 1.87270501836 is 1.87, so the answer is C.
Hence, the answer would be C. 1.87. I am 100% sure on this, for I am a pro.

Step-by-step explanation:
2. y is inversely proportional to cube of x.
When x = 2, y = 4.
Find y when x = 4
(3 Points)
Answer:
y = 0.5 at x = 4
Step-by-step explanation:
According to question,
y is inversely proportional to cube of x i.e.
[tex]y\propto \dfrac{1}{x^3}\\\\y=\dfrac{k}{x^3}[/tex]
or
[tex]k=yx^3[/tex]
Put x = 2 and y = 4 in above expression to find k.
[tex]k=4\times (2)^3\\\\=32[/tex]
Now put x = 4 to given equation to find y.
[tex]y=\dfrac{32}{4^3}[/tex]
y = 0.5 or 1/2
So, the value of y is 0.5 when x = 4.
What is the solution to the system of equations? y = 12x + 2 2y = x + 4
Answer:
(x,y)=(-28/11,16/11)
Step-by-step explanation:
hope this helps!
Answer:
x=0, y=2. (0, 2).
Step-by-step explanation:
y=12x+2
2y=x+4
------------
2(12x+2)=x+4
24x+4=x+4
24x-x=4-4
23x=0
x=0/23
x=0
y=12(0)+2
y=0+2
y=2

In a survey, patients are asked how long they sat in their doctor's waiting area. The results for two doctors are shown below.
Doctor #1 (waiting time in minutes): 5, 10, 10, 15, 20, 20, 20, 100
Doctor #2 (waiting time in minutes): 10, 10, 10, 20, 20, 20, 25, 25
Based on the results, what is the best measure of center to compare the data, and how do the measures compare?
The median is the best measure. The median waiting time for Doctor #1 is 7.5 minutes longer than for Doctor #2.
The mean is the best measure. The mean waiting time for Doctor #2 is 2.5 minutes longer than for Doctor #1.
The mean is the best measure. The mean waiting time for Doctor #1 is 7.5 minutes longer than for Doctor #2.
The median is the best measure. The median waiting time for Doctor #2 is 2.5 minutes longer than for Doctor #1.
Answer: The mean is the best measure. The mean waiting time for doctor #2 is 2.5 minutes longer than for doctor #1
