The scientists found that there were 5÷10^5 protozoa and 1×10^6 phytoplankton in the simple. how many times greater was the number of phytoplankton than the number of protozoa that were found in the sea water sample? ​

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

won't that be plagrisim thought?

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
