<span>So we wan't to know what is one third of 36. Lets say the number we are looking for is x. Then we can write this this way: x=36*(1/3). So now we get: x=36/3 and the result is: x=12. We can also do it another way: if we wan't to divide 36 into three equal parts we would get: 12 + 12 + 12 so one third of 36 is again 12.</span>
Answer:
2 - n
Step-by-step explanation:
2 decreased by n means n less than 2.
i think it would be 2 degrees every hour for 10 to 11 hours i think it would be 2 degrees

Answer:
t ≈ 0.590 s (ascent); 5.532 s (descent)
Step-by-step explanation:
We are interested in the values of t when s=16.
s = 30t -4.9t²
4.9t^2 -30t +16 = 0 . . . . . substitute 16 for s; put in standard form
The quadratic formula can be used to find the solutions:
t = (-(-30) ±√((-30)² -4(4.9)(16)))/(2(4.9))
t = (30 ±√586.4)/9.8 ≈ 0.59023, 5.53221 . . . . seconds after launch
a) It will take 0.590 seconds to reach 16 m height initially.
b) It will take 5.532 seconds to return to 16 m height on descent.
