Question

A coin weighs about 14^−2 pounds. Find the weight of 1000 of the coins. Round your answer to the nearest tenth.

Answer 1

1000 of the coins weigh about 5 pounds

Answer 2

Answer:

1000 of the coins weigh about 5.1 pounds.

Step-by-step explanation:

Consider the provided information.

A coin weighs about 14^−2pounds.

This can be written as:

$14^{-2}=\frac{1}{14^2}=\frac{1}{196}$

Now we need to find the weight of 1000 coins.

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

$\frac{1}{196}\times 1000=5.10\approx 5.1$

Hence, 1000 of the coins weigh about 5.1 pounds.
