Answer:
Step-by-step explanation:
orange part: 0.8 x 4 = 3.2
purple part: 0.8 x 0.6= 0.48
11/12 because 1/6= 2/12 and 3/4= 9/12 and when u add them u get 11/12
You have to move your variables around.<span />
The population triples ( P × 3 ) every ten minutes...
So if ten minutes is reached there will be 1,200 bacteria.
Edited - missed the question
** The units for time should be in minutes.
P = 400 × 3^(t/10)
at t = 0 ; P = 400
at t = 10 ; P = 1,200
When P = 600
600 = 400 × 3^(t/10)
6/4 = 3^(t/10)
Log(3/2) = Log(3^(t/10))
power rule
Log(3/2) = (t/10) Log(3)
10 × Log(3/2)/Log(3) = t
3.69 minutes the population will be at 600 bacteria
Unites for time are in minutes.
Answer:
99°
Step-by-step explanation:
<8 = 99° [Since, corresponding angles of parallel lines]
