Answer:
volume = 502.4 cm³
Step-by-step explanation:
volume = 4²π(10) = 160π = 502.4 cm³
N = 10(2)^t where N = number of bacteria and t = time in multiples of 3 hours
So when t = 24/3 we have
N = 10 (2)^8 = 2560 answer
Answer:
A. 3.6 kilometers
Step-by-step explanation:
1000 meters = 1 km
3600 meters = x km
Set as a ratio:
1000 : 1 = 3600 : x
Then divide:
![\frac{3600}{1000} = \frac{x}{1} = x](https://tex.z-dn.net/?f=%5Cfrac%7B3600%7D%7B1000%7D%20%3D%20%5Cfrac%7Bx%7D%7B1%7D%20%3D%20x)
so 3600/1000 = 3.6 = x
3.6 km
Answer:
20 m
Step-by-step explanation:
The width is half the length, and the perimeter is the sum of the lengths of all sides. We can write the equation of the perimeter as ...
... 60 m = L + L/2 + L + L/2
... 60 m = 3L . . . . . collect terms
... 20 m = L . . . . . . divide by 3
