Starting with N = N₀·(1+r)^(t/4)
where N is the number of bacteria at t hours, r is the growth rate, and N₀ is the initial number of bacteria
N₀ = 64
r = 50% = 0.5
So the formula is:
N = 64 · (1+0.5)^(t/4)
N = 64·(1.5)^(t/4)
So after 100 hours,
N = 64 · (1.5)²⁵ = 1.6×10⁶
There are 1.6×10⁶ bacteria at 100 hours.
Answer:
7 times
Step-by-step explanation:
5 times 5 is 25 so 5 times 7 is 35 and thats the answer
I’m pretty sure it’s x=40
Answer:
47 and 54
Step-by-step explanation:
101 - 7 = 94
94/2 = 47
47 + 7 = 54
ABC is an isosceles triangle so AB = AC
Plug in
8x - 4 = 5x + 11
3x = 15
x = 5
BC = 4x - 2 = 4(5) - 2 = 20 - 2 = 18
Answer
BC = 18 units
