Answer:
Step-by-step explanation:
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

Answer:
8.71 x 10^3N - C
Step-by-step explanation:
Force = mass x acceleration
mass = 1.7 x 10^3 and acceleration = 4.75m/s^2
Force = 1.7 x 10^3 x 4.75 = 8075N = 8.71 x 10^3N
Answer:
It can never be a prime number.
Step-by-step explanation:
This is because the product of the two prime numbers are divisible by those two numbers, therefore going against the definition of a prime number. For example 3 and 5 are prime numbers and their product is 15. 15 can be divided by 3 and 5 so it is not a prime number.
Hope this helps.
