Answer:
1.) [B]
2.) [C]
(3.) [D]
Step-by-step explanation:
1.) Initial amount = $3168
Annual percentage rate = 12.75
per month percentage rate = 1.06%
Interest after 3 months = P*R*T/100
= 3168*1.06*3/100
= 100.74 (aprox)
Balance after 3 months = 3168-100.74
= $3270.06 (aprox) (B.)
2.) Gross pay = $2759
Total interest rate = 7.65%+12%+7% = 26.65%
interest amount= 26.65% *2759 =$728.24 (aprox)
Housing and fixing expenses= $728.54 (C.)
3.) 1 hour = $8.25
1 week= 35 hours
3 weeks = 35*3 hours = 105 hours
Total income= 105 hours = $8.25*105= $866.25
Total interest to be deducted = 7.65+13+9 = 29.65 %
Income after deducting interest = $866.25-256.843 = $609.407
(D.)

Step-by-step explanation:
The doubling period of a bacterial population is 15 minutes.
At time t = 90 minutes, the bacterial population was 50000.
Round your answers to at least 1 decimal place.
:
We can use the formula:
A = Ao*2^(t/d); where:
A = amt after t time
Ao = initial amt (t=0)
t = time period in question
d = doubling time of substance
In our problem
d = 15 min
t = 90 min
A = 50000
What was the initial population at time t = 0
Ao * 2^(90/15) = 50000
Ao * 2^6 = 50000
We know 2^6 = 64
64(Ao) = 50000
Ao = 50000/64
Ao = 781.25 is the initial population
:
Find the size of the bacterial population after 4 hours
Change 4 hr to 240 min
A = 781.25 * 2^(240/15
A = 781.25 * 2^16
A= 781.25 * 65536
A = 51,199,218.75 after 4 hrs
Both 15 and 20 can be divided evenly by 5, so 5 is the greatest common monomial: 5(3x^2 + 4x) or 5x(3x + 4)
Answer: the answer is 2.5
