1 oz = 0.0625 lb
Ratio of the hiker an backpack in the first row = 152.25 lb : 14.5 lb
= 21 : 2
Hiker's weight Backpack weight Total weight (in lb)
1). 152 lb 4 oz 14 lb 8 oz (152+14) lb (4+8) oz = 164lb 12oz
= 16.75 lb
2). 107 lb 10 oz 10 lb 4 oz (107+10) lb (10+4) oz = 117 lb 14 oz
= 117.875 lb
3). 129 lb 15 oz
(129+12) lb (15+6)oz = 141 lb 21 oz
x = 12.375 lb = 142.3125lb
x = 12 lb 6 oz
4).
8 lb 12 oz (8 + 91) lb (14+12) oz = 99 lb 26 lb
x = 91.875 lb = 100.625 lb
x = 91 lb 14 oz
5).
10 lb (105 + 10) lb = 115 lb
x = 105 lb

Step-by-step explanation:
I hope that the answer is clear
Fidn volume
V=hpir^2
d/2=r
1.4/2=0.7=r
height=3.5
V=3.5*3.14*0.7^2
V=5.3851
1.5 times t=5.3851
divide both sides by 1.5
t=3.59
round
t=4
