Answer:
N(t)=N∗.5t/h where n(t) is amount of substance left, N = initial amount, t = current time, and h = half-life time.h = 24 hours t= 45 hours, N = 130mg
therefore, N(t)=130∗.545/24=35.44mg
Step-by-step explanation:

Answer:
4km/h
Step-by-step explanation:
the speed is equals to distance/time
distance/time=10km/2.5h
=4kh/h
All I can say is that your equation is wrong
Answer:
<u>0.952</u>
Step-by-step explanation:
<u>Given</u> :
- opposite side of 80 inches
- adjacent side of 84 inches
- hypotenuse of 116 inches
<u>Solving</u> :
- tan(θ) = opposite / adjacent
- tan(θ) = 80/84 = 20/21
- tan(θ) = <u>0.952</u>
