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
