A feather weighs 0.0082 g. How many feathers would you need to make a way of 4.1*10³ g? Write the answers in scientific notation.

1 answer

To find out how many feathers you would need to weigh 4.1 × 10³ g, you can use the following formula:

\[ \text{Number of feathers} = \frac{\text{Total weight}}{\text{Weight of one feather}} \]

Given that the weight of one feather is 0.0082 g, you can substitute the values into the formula:

\[ \text{Number of feathers} = \frac{4.1 \times 10^3 , \text{g}}{0.0082 , \text{g}} \]

Now, perform the division:

  1. First, convert 0.0082 g to scientific notation: \[ 0.0082 , \text{g} = 8.2 \times 10^{-3} , \text{g} \]

  2. Now, substitute this back into the equation: \[ \text{Number of feathers} = \frac{4.1 \times 10^3}{8.2 \times 10^{-3}} \]

  3. Perform the division: \[ \text{Number of feathers} = \frac{4.1}{8.2} \times \frac{10^3}{10^{-3}} = 0.5 \times 10^6 \]

  4. Convert \(0.5 \times 10^6\) to proper scientific notation: \[ 0.5 \times 10^6 = 5.0 \times 10^5 \]

Thus, you would need approximately \(5.0 \times 10^5\) feathers to weigh 4.1 × 10³ g.
