kendra finds the dimensions of a sticky note. she uses a meter stick to determine that the dimensions are 1.25 times 10^-8 meters wide by 2.5 times 10^-6 meters long. use scientific notation to write dimensions in millimeters
To convert the dimensions from meters to millimeters, we need to multiply them by 1000 since there are 1000 millimeters in 1 meter.
The width is 1.25 x 10^-8 meters, which is equal to 1.25 x 10^-8 x 1000 millimeters (since 1 meter = 1000 millimeters). This can be simplified as 1.25 x 10^-8 x 10^3 millimeters.
Simplifying further, we can add the exponents and compute the result: 1.25 x 10^-8 x 10^3 = 1.25 x 10^-8+3 = 1.25 x 10^-5 millimeters wide.
The length is 2.5 x 10^-6 meters, which is equal to 2.5 x 10^-6 x 1000 millimeters. Simplifying, 2.5 x 10^-6 x 10^3 = 2.5 x 10^-6+3 = 2.5 x 10^-3 millimeters long.
Thus, the dimensions in millimeters are approximately 1.25 x 10^-5 millimeters wide by 2.5 x 10^-3 millimeters long.
To convert the dimensions from meters to millimeters, we need to multiply by 1000 since there are 1000 millimeters in 1 meter.
The width of the sticky note is 1.25 times 10^-8 meters. To convert this to millimeters, we multiply by 1000:
1.25 times 10^-8 meters * 1000 = 1.25 times 10^-5 millimeters
The length of the sticky note is 2.5 times 10^-6 meters. To convert this to millimeters, we also multiply by 1000:
2.5 times 10^-6 meters * 1000 = 2.5 times 10^-3 millimeters
Therefore, the dimensions of the sticky note in millimeters are 1.25 times 10^-5 millimeters wide by 2.5 times 10^-3 millimeters long.
To convert the dimensions from meters to millimeters using scientific notation, follow these steps:
1. Convert 1.25 times 10^-8 meters to millimeters:
- 1 meter = 1000 millimeters (by definition)
- Multiply 1.25 by 1000 to convert it to millimeters: 1.25 * 1000 = 1250.
- Note that the exponent remains the same: 10^-8.
2. Convert 2.5 times 10^-6 meters to millimeters:
- Multiply 2.5 by 1000: 2.5 * 1000 = 2500.
- Again, the exponent remains the same: 10^-6.
Therefore, the dimensions in millimeters using scientific notation are:
- Width: 1.25 times 10^-8 meters = 1.25 times 10^-5 millimeters (in scientific notation)
- Length: 2.5 times 10^-6 meters = 2.5 times 10^-3 millimeters (in scientific notation)
