<span>Answer:
I assume you're looking for a time-weighed average rather than just the [H(0) + H(60)]/2 average.
Havg = (1/60)â«[20+980e^(-0.1t)]dt (evaluated from 0 to 60)
Havg = (1/60)[20t - 98e^(-0.1t)] evaluated from 0 to 60
Havg = (1/60)[20(60) - 98e^(-6) - 20(0) + 98e^(0)] = 1297.76/60 = 21.629 °C</span>

hope this helps
Step-by-step explanation:
3*2 * 1 = 24 ways . It is called arrangement or permutations, while if you need to group some objects it is called combination and there we need to consider unique groups only.
Should be the fourth answer.
I think it is 555??
355+200=555
Answer:
You divide what you got by how many questions there are. For example, if you got 18/20, you'd divide 18 by 20 with a calculator. Which would be 0.9, then you move the decimal over 2 times making it 90, so you got 90%
