Answer:
y = 187
Step-by-step explanation:
248=61-y
248 - 61 = 61 - y - 61
y = 187
The answer is -10! Glade I could help!!
0.10c + 0.12b = 2.18
c = 4b + 1
0.10(4b + 1) + 0.12b = 2.18
0.40b + 0.10 + 0.12b = 2.18
0.40b + 0.12b = 2.18 - 0.10
0.52b = 2.08
b = 2.08 / 0.52
b = 4 <==== she had 4 bottles
c = 4b + 1
c = 4(4) + 1
c = 16 + 1
c = 17 <=== she had 17 cans
<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>
