Answer:
After 5 months
Step-by-step explanation:
Step one:
given data
LA Fitness charges a registration fee of $75 plus $35.75 per month for members
let the number of months be x
and the total charges be y
total is
y= 75+35.75x----------1
Gold's Gym charges a registration fee of $164 plus $17.95 for members
let the number of months be x
and the total charges be y
total is
y= 164+17.95x----------2
Step two:
equate 1 and 2
75+35.75x= 164+17.95x
solve for x
35.75x-17.95x=164-75
17.8x=89
divide both sides by 17.8
x=89/17.8
x=5 months
The area of any triangle = (1/2) x (length of the base) x (height)
2.5 centimeters = 0.025 meter
The area of the sail is (3.75) = (0.5) x (0.025) x (height)
Multiply each side by 2 : (7.5) = (0.025) x (height)
Divide each side by 0.025 : (7.5)/(0.025) = height =<em> 300 meters</em>
The situation is stupid, but the math is bullet-proof.
It depends on whether you have "Perpendicular" or "base"
If you have perpendicular then, you can use the formula:
sin Ф = P / H
If you have base then, you can use the formula:
cos Ф = B/ H
Hope this helps!
