Answer:
S/2πr-r = h
Step-by-step explanation:
S = 2πr(h + r)
S/2πr = h+r
S/2πr - r = h
0.59 = (1 - 0.000125)^^x where x = number of years of decay
ln 0.59 = x ln(0.999875)
x = 4221 to nearest year
First you would need to add up all of the data given, then divide the sum by 9 because there is 9 pieces of data. So it would be 229/9=25.4444444 repeating.
Answer:
$199.89
Step-by-step explanation:
The bike costs 266.52
The parents are contributing one fourth of this (1/4)
We need to find 1/4th of 266.52
Divide 266.52 by 4 to find out how much Justin's parents are contributing to the bike
The answer is 66.63
Now subtract 66.63 from 266.52
Justin has to pay a total of 199.89
