Kendra finds the dimensions of a sticky note. She uses a meter stick to determine that the dimensions are 1.25 x 10^-8 meters wide by 2.5 x 10^-6 meters long. Use scientific notation to write the dimensions in millimeters.
Note: 1 meter is equal to 1,000 millimeters
(1 point)
1.25 x 10^-11 by 2.5 x 10^-9
1.25 x 10^-5 by 2.5 x 10^-3
1.25 x 10^-10 by 2.5 x 10^-8
1.25 x 10^-6 by 2.5 x 10^-4
To convert meters to millimeters, we need to multiply by the conversion factor: 1 meter = 1,000 millimeters.
The width is 1.25 x 10^-8 meters
1.25 x 10^-8 meters * 1,000 millimeters/1 meter = 1.25 x 10^-8 * 1,000 = 1.25 x 10^-5 millimeters
The length is 2.5 x 10^-6 meters
2.5 x 10^-6 meters * 1,000 millimeters/1 meter = 2.5 x 10^-6 * 1,000 = 2.5 x 10^-3 millimeters
Therefore, the dimensions in millimeters are 1.25 x 10^-5 by 2.5 x 10^-3 (option 2).
