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. Choose the correct answer from below (note: 1 meter = 1,000 millimeters):
1.25 × 10⁻¹⁰ by 2.5 × 10⁻⁸
1.25 × 10⁻⁶ by 2.5 × 10⁻⁴
1.25 × 10⁻¹¹ by 2.5 × 10⁻⁹
1.25 × 10⁻⁵ by 2.5 × 10⁻³
To convert the dimensions from meters to millimeters, we multiply each dimension by 1,000.
Width: 1.25 × 10⁻⁸ meters × 1,000 = 1.25 × 10⁻⁸ × 1,000 = 1.25 × 10⁻⁸ × 10³ = 1.25 × 10⁻⁵ millimeters
Length: 2.5 × 10⁻⁶ meters × 1,000 = 2.5 × 10⁻⁶ × 1,000 = 2.5 × 10⁻⁶ × 10³ = 2.5 × 10⁻³ millimeters
So, the correct answer is 1.25 × 10⁻⁵ by 2.5 × 10⁻³.
To convert the dimensions from meters to millimeters, we need to multiply each dimension by 1,000 (since 1 meter = 1,000 millimeters).
The given dimensions are 1.25 × 10⁻⁸ meters wide and 2.5 × 10⁻⁶ meters long.
To convert 1.25 × 10⁻⁸ meters to millimeters, we multiply by 1,000:
1.25 × 10⁻⁸ meters = 1.25 × 10⁻⁸ × 1,000 = 1.25 × 10⁻⁸ × 10³ = 1.25 × 10⁻⁸+³ = 1.25 × 10⁻⁵ millimeters
To convert 2.5 × 10⁻⁶ meters to millimeters, we multiply by 1,000:
2.5 × 10⁻⁶ meters = 2.5 × 10⁻⁶ × 1,000 = 2.5 × 10⁻⁶ × 10³ = 2.5 × 10⁻⁶+³ = 2.5 × 10⁻³ millimeters
Therefore, the dimensions in millimeters are 1.25 × 10⁻⁵ by 2.5 × 10⁻³.
The correct answer is: 1.25 × 10⁻⁵ by 2.5 × 10⁻³.
To convert the dimensions from meters to millimeters, we need to multiply them by 1,000 (since 1 meter = 1,000 millimeters).
The given dimensions are:
Width: 1.25 × 10⁻⁸ meters
Length: 2.5 × 10⁻⁶ meters
To convert the width to millimeters, we can multiply it by 1,000:
1.25 × 10⁻⁸ meters × 1,000 millimeters/1 meter = 1.25 × 10⁻⁸ × 1,000 millimeters = 1.25 × 10⁻⁸ × 1,000 = 1.25 × 10⁻⁵ millimeters
Therefore, the width in millimeters is 1.25 × 10⁻⁵.
To convert the length to millimeters, we can also multiply it by 1,000:
2.5 × 10⁻⁶ meters × 1,000 millimeters/1 meter = 2.5 × 10⁻⁶ × 1,000 millimeters = 2.5 × 10⁻⁶ × 1,000 = 2.5 × 10⁻³ millimeters
Therefore, the length in millimeters is 2.5 × 10⁻³.
Thus, the dimensions of the sticky note in millimeters are 1.25 × 10⁻⁵ by 2.5 × 10⁻³.
So the correct answer is: 1.25 × 10⁻⁵ by 2.5 × 10⁻³.
