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
milimeters.
Note: 1 meter is equal to 1,000 millimeters.
(1 point)
O 1.25 × 10 10 by 2.5 × 10 8 millimeters
O 1.25 × 10 5 by 2.5 × 10 3 millimeters
O 1.25 x 10 € by 2.5 × 10 1 millimeters
O 1.25 x 10 11 by 2.5 x 10 9 millimeters
To convert the dimensions from meters to millimeters, we need to multiply them by 1000 since 1 meter is equal to 1000 millimeters.
The width of the sticky note is 1.25 x 10^-8 meters. Multiplying this by 1000, we get:
1.25 x 10^-8 m * 1000 = 1.25 x 10^-5 millimeters
The length of the sticky note is 2.5 x 10^-6 meters. Multiplying this by 1000, we get:
2.5 x 10^-6 m * 1000 = 2.5 x 10^-3 millimeters
Therefore, the dimensions of the sticky note in millimeters are 1.25 x 10^-5 by 2.5 x 10^-3.
The correct answer is:
1.25 x 10^-5 by 2.5 x 10^-3 millimeters.
To convert the dimensions from meters to millimeters, we need to multiply each dimension by 1,000.
Given:
Width = 1.25 x 10^-8 meters
Length = 2.5 x 10^-6 meters
To convert the width:
1.25 x 10^-8 meters * 1000 millimeters/1 meter = 1.25 x 10^-8 * 1000 = 1.25 x 10^-8 * 10^3 = 1.25 x 10^-5 millimeters
To convert the length:
2.5 x 10^-6 meters * 1000 millimeters/1 meter = 2.5 x 10^-6 * 1000 = 2.5 x 10^-6 * 10^3 = 2.5 x 10^-3 millimeters
Therefore, the dimensions in millimeters are:
Width = 1.25 x 10^-5 millimeters
Length = 2.5 x 10^-3 millimeters
In scientific notation, this can be written as:
1.25 x 10^-5 by 2.5 x 10^-3 millimeters.
So the correct answer is:
1.25 x 10^-5 by 2.5 x 10^-3 millimeters.
To convert the dimensions from meters to millimeters, we need to multiply by 1,000 because there are 1,000 millimeters in one meter.
Width: 1.25 x 10^-8 meters
1.25 x 10^-8 meters * 1,000 millimeters/meter = 1.25 x 10^-8 * 1,000 millimeters = 1.25 x 10^-5 millimeters
Length: 2.5 x 10^-6 meters
2.5 x 10^-6 meters * 1,000 millimeters/meter = 2.5 x 10^-6 * 1,000 millimeters = 2.5 x 10^-3 millimeters
So, the dimensions of the sticky note in millimeters is:
1.25 x 10^-5 by 2.5 x 10^-3 millimeters
Therefore, the correct answer is:
1.25 x 10^-5 by 2.5 x 10^-3 millimeters
