# Math Help - got it I think

1. ## got it I think

if 1. How long does each node transmit for in every hour? Express your answer in seconds.

33 ms = 33 x 10-3 s = 0.033 s
So, the duty cycle is (0.033 s ÷ T s) x 100% = 3%
Transposing the formula gives T s =

if 0.033 equates to 3% of the time then how do I what 93% is

2. ## Re: got it I think

Hey fatherjack.

Hint: if you have 3# then getting 100% is gained by multiplying by 100%/3% or 1/0.03 = 100/3. To get 3% you take this and multiply by 0.93 = 93%/100% as expressed in fraction form.
