Hey there!
When we put a number in scientific notation, we want the first number to be at least 1 and less than 10. There must be a digit from 1-9 in the ones place.
With the number 0.000015, we can move the decimal place 5 places to the right and we have 1.5, which is more than one and less than ten.
Because we moved the decimal place 5 places to the right, 1.5 is multiplied by 10 to the power of -5.
The 5 is the number of places the decimal is moved, and the negative sign is because we moved it to the right.
10^(-5) is the same as 0.00001, just for context.
So, 0.000015 meters in scientific notation is 1.5 x 10^(5) meters.
Hope this helps!

B
Step-by-step explanation:
the first fish tank has 100 gallons of water and 1 gallon is removed every hour which makes 100-h
the second tank has 40 gallons in it and 2 gallons are added every hour which makes 40+2h
after 20 hours the second tank will have more gallons than the first tank
this means that 40+2h would be greater than 100-h since it's also asking you "After how many hours will the first tank have less water than the second?"
