Answer:
Distance between the person and the plane is 12 miles
Step-by-step explanation:
From the figure attached,
An airplane is flying at an altitude AB = 6 miles.
An observer is standing at point C from where he observes the plane at an angle of elevation θ
Therefore, sinθ = 
sinθ = 
AC = 
AC = 6cosecθ
If angle θ = 30°
Then AC = 6cosec30
AC = 6×2
AC = 12 miles
Therefore, distance between the person and the plane is 12 miles.
Answer:
In this question the <em>y</em> is 3.
Step-by-step explanation:
3 x 3 is 9.
9 + 1.8 = 10.8
In the table it shows that 1 hour corresponds to $25. Or if you want to check it, simply take any value and divide it by its corresponding hour ( ex. 50/2 or 75/3) Hope this helps!
I believe it's 4. 1/2 = 1/4
so, 1/2 + 1/2 + 1/2 + 1/2 would be 4/4...
