Answer:
yes
Step-by-step explanation:
because area of sphere equals =
![4\pi \: r{2}](https://tex.z-dn.net/?f=4%5Cpi%20%5C%3A%20r%7B2%7D%20)
so if we doubled the radius the surface area will be doubled
Answer:
the answer is 6
Step-by-step explanation:
because 33 minutes to 5pm is 76 min so you divide 76 by 12 so its 6
Answer:
After 16 hours bacterial count will be 11600.
Step-by-step explanation:
Bacterial growth is always an exponential growth in a given culture.So the formula for the growth will be
Final counts of bacteria = Initial counts × ![(rate of growth)^{time}](https://tex.z-dn.net/?f=%28rate%20of%20growth%29%5E%7Btime%7D)
Given from first part Initial counts = 5000
Final counts= 6500 and time of growth = 5 hours
Then we will get the value of rate of growth of bacteria from the bacteria
⇒ 6500 = 5000×![(rate)^{5}](https://tex.z-dn.net/?f=%28rate%29%5E%7B5%7D)
![(rate)^{5}= \frac{6500}{5000} = 1.3](https://tex.z-dn.net/?f=%28rate%29%5E%7B5%7D%3D%20%5Cfrac%7B6500%7D%7B5000%7D%20%3D%201.3)
![Rate = \sqrt[5]{1.3} = 1.05](https://tex.z-dn.net/?f=Rate%20%3D%20%5Csqrt%5B5%5D%7B1.3%7D%20%3D%201.05)
Now again to get the value of bacteria after 16 hours
Final Count = 5000×![(1.05)^{16}](https://tex.z-dn.net/?f=%281.05%29%5E%7B16%7D)
= 5000×2.32
= 11600
There's a website called desmos.com. That website can tell you the answer
Answer: 5
Step-by-step explanation: There are 2.5 cm per in, so its just 2.5*2
