Question Kendra finds the dimensions of a sticky note. She uses a meter stick to determine that the dimensions are 1.25×10−8 meters wide by 2.5×10−6 meters long. Use scientific notation to write the dimensions in millimeters. Note: 1 meter is equal to 1,000 millimeters. (1 point)

Answer 1

To convert the dimensions from meters to millimeters, we need to multiply the dimensions by 1,000, since 1 meter is equal to 1,000 millimeters.

1. Width: \[ 1.25 \times 10^{-8} \text{ meters} \times 1000 \text{ mm/m} = 1.25 \times 10^{-8} \times 10^{3} \text{ mm} = 1.25 \times 10^{-5} \text{ mm} \]

2. Length: \[ 2.5 \times 10^{-6} \text{ meters} \times 1000 \text{ mm/m} = 2.5 \times 10^{-6} \times 10^{3} \text{ mm} = 2.5 \times 10^{-3} \text{ mm} \]

Thus, the dimensions of the sticky note in millimeters are:

• Width: \(1.25 \times 10^{-5}\) mm
• Length: \(2.5 \times 10^{-3}\) mm
