8/1600 as a percentage is 0.5%
To determine the extent of how many times greater is the number of bacteria in petri dish A than petri dish B, we simply have to take the ratio of the two.
1.75 x 10^18 / 6.25 x 10^15 = 280
So the bacteria in petri dish A is 280 times larger.
In scientific notation:
2.8 x 10^2
Hope this helps :)
Step-by-step explanation:
In order to properly distribute, multiply the number on the outside of the parenthesis by the numbers on the inside.
Here is an example:
This simplifies to:
Answer:
180
Step-by-step explanation:
A negative by negative is positive. So, you can pretend that the numbers are 6 and 30. Product means the answer for multiplication. In this case, product of 6 and 30 is 180. The product of -6 and -30 is 180.
Therefore, the answer is 180.
