Law Incorporation [45]
Gordon gets £72

Explanation:
Sarah gets twice as much as Gordon and Gordon gets three times as much as Malachy, which means that Malachy gets 1 part of the money, Gordon gets 3 parts because he has three times as much as Malachy, and Sarah gets 6 because she gets twice as much as Gordon. As a ratio from Sarah to Gordon to Malachy its 6:3:1. All of that adds up to £240. If u add 6+3+1 it gives you 10. 240/10 is £24. And Gordon has 3 parts so you do 3x24 which gives you £72

kari74 [83]

Answer:

1131 pounds.

Step-by-step explanation:

We have been given that an unloaded truck and trailer, with the driver aboard, weighs 30,000 pounds. When fully loaded, the truck holds 26 pallets of cargo, and each of the 18 tires of the fully loaded semi-truck bears approximately 3,300 pounds.

First of all, we will find weight of 18 tires by multiplying 18 by 3,300 as:

\text{Weight of tires of the fully loaded semi-truck}=18\times 3,300

\text{Weight of tires of the fully loaded semi-truck}=59,400

The weight of 26 pallets would be weight of 18 tires minus weight of unloaded truck.

\text{Weight of 26 pallets of cargo}=59,400-30,000

\text{Weight of 26 pallets of cargo}=29,400

Now, we will divide 29,400 by 26 to find average weight of one pallet of cargo.

\text{Average weight of one pallet of cargo}=\frac{29,400}{26}

\text{Average weight of one pallet of cargo}=1130.769230769

\text{Average weight of one pallet of cargo}\approx 1131

Therefore, the average weight of one pallet of cargo is approximately 1131 pounds.
