To determine how many bacteria will be in 100 milliliters of coastal ocean water, given that there are about 1,500,000 bacteria per milliliter, we need to perform a simple multiplication:
1. Understand the given information:
- There are 1,500,000 bacteria in 1 milliliter of water.
2. Determine our goal:
- We want to find out how many bacteria will be in 100 milliliters of water.
3. Calculation:
- The number of bacteria in 1 milliliter is 1,500,000.
- We need to multiply this by the number of milliliters, which is 100.
[tex]\[
\text{Total bacteria} = \text{Bacteria per milliliter} \times \text{Number of milliliters}
\][/tex]
[tex]\[
\text{Total bacteria} = 1,500,000 \times 100
\][/tex]
4. Perform the multiplication:
[tex]\[
1,500,000 \times 100 = 150,000,000
\][/tex]
So, there are 150,000,000 bacteria in 100 milliliters of water.
The answer in scientific notation is:
[tex]\[
150,000,000 = 1.5 \times 10^8
\][/tex]
Thus, the correct answer is:
E. [tex]\(1.5 \times 10^8\)[/tex]
