Question

You use a microscope to look at bacteria that is 0.0034 millimeter long. The microscope magnifies the bacteria 430 times. How long does the bacteria appear to be when you look at it through the microscope?

Answer 1

ANSWER: 1.562
move the decimal point of 0.0034 to the right to make it a whole number which is 34. Then multiply 34 times 430 which is 15,620.
move the decimal point (which is at the end) 4 times to the left
the answer will be 1.562

Answer 2

1.462 millimeters.

Explanation:

You use a microscope to look at bacteria that is 0.0034 millimeter long.

The microscope magnifies the bacteria 430 times.

So the bacteria appears 430 times long through the microscope.

We will multiply the length of bacteria by 430.

The size of bacteria appear = 430 × 0.0034

= 1.462 millimeters

The length of the bacteria would appear 1.462 millimeters through microscope.
