Harriet is cultivating a strain of bacteria in a petri dish. currently, she has 103 bacteria in the dish. the bacteria divide every two hours such that the number of bacteria has doubled by the end of every second hour. how many bacteria will harriet have in the dish at the end of 6 hours?

To find this, you have to solve 103(2^t)
Since there are 103 bacteria to begin with, you multiply this by how often the bacteria divides (every two hours) to the power of how many times they have divided in that time, or t. The bacteria has divided 3 times in 6 hours.

The final answer is 824 bacteria

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
