The size of a cell is typically found by capturing an image under a microscope then using software to measure its diameter. Two cells are measured using this method:

cell D: 8.39 x 10^-3 centimeters
Cell E: 4.4 x 10^-4
How much larger is the diameter of cell D than the diameter of cell E? Express your answer using scientific notation.

To find out how much larger the diameter of cell D is than the diameter of cell E, we need to calculate the ratio of their sizes:

Ratio = (8.39 x 10^-3) / (4.4 x 10^-4)

Simplifying this calculation gives:

Ratio = (8.39 / 4.4) x 10^-3 / 10^-4
Ratio = 1.89772727273 x 10^(3-(-4))
Ratio = 1.89772727273 x 10^7

Therefore, the diameter of cell D is approximately 18,977,272.73 times larger than the diameter of cell E. This can be expressed in scientific notation as 1.89772727273 x 10^7.

are you sure

I apologize for the mistake in my previous response. Let's recalculate the ratio correctly:

Ratio = (8.39 x 10^-3) / (4.4 x 10^-4)

Simplify this calculation:

Ratio = (8.39 / 4.4) x 10^(-3 - (-4))
Ratio = 1.89772727273 x 10^1
Ratio = 18.9772727273

Therefore, the diameter of cell D is approximately 18.98 times larger than the diameter of cell E. This can be expressed in scientific notation as 1.89772727273 x 10^1. Thank you for highlighting the error, and I appreciate your understanding.
