Answer:
10800
Step-by-step explanation:
The number of bacteria in a colony growing exponentially. At 4 pm yesterday the number of bacteria is 400.And at 6 pm yesterday it was 3600. How many bacteria in the colony at 7 pm?
Step-by-step explanation:
B = B₀ Kⁿ
At 4 pm yesterday the number of bacteria is 400
B₀ = 400
n = number of hrs
at 6 pm yesterday it was 3600 => n = 6- 4 = 2 hrs
B₂ = 3600
=> 3600 = 400 * k²
=> k² = 9
=> k = 3
At 7 Pm Yesterday
n = 7-4 = 3
B₃ = 400 * 3³
=> B₃ = 27 * 400
=> B₃ = 10800
bacteria in the colony at 7 pm = 10800
or B₂ = 3600 & n = 7-6 = 1
Then B₃ = 3600 * 3¹ = 10800
And boom here
Answer:
top right
Step-by-step explanation:
If you imagine yourself building with that model you can see its that one
Do cross-multiplication
<span>72/x = 60/100 </span>
<span>so </span>
<span>60 times x = 72 times 100 </span>
<span>so </span>
<span>60x = 7200 </span>
<span>then divide both sides by 60 </span>
<span>x = 120</span>
