Answer:
The parasailor height is 47ft
Step-by-step explanation:
We can think of the problem as a right triangle, the string would be the hypotenuse and the height of the parasailor would be a leg.
well to start we have to know the relationship between angles, legs and the hypotenuse
α = 36°
a: adjacent
o: opposite = ?
h: hypotenuse = 80ft
sin α = o/h
cos α= a/h
tan α = o/a
we see that it has (angle, hypotenuse, opposite)
is the sine
sin α = o/h
sin 36° = o/80
sin 36° * 80 = o
47.02 = o
if we round to the nearest tenth
47.02 = 47.0
The parasailor height is 47ft
Let the number of songs owned by Lou be = x.
Kelly has 4 times as many songs as Lou = 4x
Tiffany has 6 times as many songs as Lou = 6x
They all have total of 682 songs
= x + 4x + 6x = 682
11x = 682
x = 682 / 11 .
x =62.
How many songs Kelly has = 4x = 4*62 = 248 songs.
<span>Kelly = 248 songs.</span>
Answer:
First, let's write the problem.
4+3s-9s=22
Add like terms,
4-6s=22
Subtract 4 from both sides.
4-6s-4=22-4
-6s=18
Divide both sides by -6.
\frac{-6s}{-6}=\frac{18}{-6}
Our final answer would be,
s=-3
