Answer:

1000 of the coins weigh about 5.1 pounds.

Explanation:

Consider the provided information.

A coin weighs about 14^−2pounds.

This can be written as:

14^(-2)=(1)/(14^2)=(1)/(196)

Now we need to find the weight of 1000 coins.

To find this simply multiply the weight of one coin with 1000.

$(1)/(196)* 1000=5.10\approx 5.1$

Hence, 1000 of the coins weigh about 5.1 pounds.
