In a circle the measure of a CENTRAL angle = measure of the arc intercepted.
mes Angle ACB = mes Arc AB:
3x+20 = 65x-4
24 = 65x -3x
62x = 24
x = 24/62 = 12/31 = 0.3871
Answer:
Step-by-step explanation:
distance between -3/7 and 2/8
Answer:
a) 12 points
b) A: 3 questions; B: 2 questions
Step-by-step explanation:
The least number of points each section may have is the least common multiple of 4 and 6. That is a number that will have all of the factors of 4 and all of the factors of 6: 2×2×3 = 12.
<h3>a)</h3>
Each part is worth 12 points.
<h3>b)</h3>
Part A has 12/4 = 3 questions.
Part B has 12/6 = 2 questions.
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.
