Answer:
16
Step-by-step explanation:
use the formula (b/2)^2 to find what number to add to each side of the equation
-1.8, -1.7, -8/5, 1.5, -4/3, -6/5,
Answer:
The bacteria took 1 hour and 40 minutes to fill the first bottle and it took only 10 minutes to fill 3 more. This is because of the amount of bacteria, for the first bottle there were only a few so it took them time to grow and multiply but once there were a lot the process starts to get faster. Think of it like this if you have 1 bacteria it will multiply into 2 bacteria. The 2 will multiply into 4, then 8, 16, 32, 62, 124 and so on. Do you notice how the numbers are getting bigger every time? Each number is being multiplied by 2 so the growth rate speeds up very quickly, which is why it took the bacteria 1 hour and 40 minutes to fill the first bottle and only 10 minutes to fill the other 3.
(I'm not sure but this is my theory)
The opposite of his negative number would be a positive number.
For example, If he picked -7, the opposite would be 7.
I hope I helped!
Answer:
75 pi
Step-by-step explanation:
Volume of a cylinder is given by
V = pi r^2h
V = pi (5)^2 (3)
= pi (25)*3
= 75pi
