Answer:
2201.8348 ; 3 ; x / (1 + 0.01)
Step-by-step explanation:
1)
Final amount (A) = 2400 ; rate (r) = 6% = 0.06, time, t = 1.5 years
Sum = principal = p
Using the relation :
A = p(1 + rt)
2400 = p(1 + 0.06(1.5))
2400 = p(1 + 0.09)
2400 = p(1.09)
p = 2400 / 1.09
p = 2201.8348
2.)
12000 amount to 15600 at 10% simple interest
A = p(1 + rt)
15600 = 12000(1 + 0.1t)
15600 = 12000 + 1200t
15600 - 12000 = 1200t
3600 = 1200t
t = 3600 / 1200
t = 3 years
3.)
A = p(1 + rt)
x = p(1 + x/100 * 1/x)
x = p(1 + x /100x)
x = p(1 + 1 / 100)
x = p(1 + 0.01)
x = p(1.01)
x / 1.01 = p
x / (1 + 0.01)
Answer:
the EOQ cost function
Step-by-step explanation:
Given that:
Total cost = Purchase Cost + Ordering Cost + Holding Cost
i.e
T =
By differentiating with respect to Q and equating to zero, we have:
Now;
Therefore:
the EOQ cost function

Answer:
1086.3 cm²
Step-by-step explanation:
surface are of sphere = πD²
SA = (3.14)(18.6 cm)^2
SA = 1086.3 cm²
Answer:
26 mph
Step-by-step explanation:
First find the time Adrian takes to get to school
I found it easiesT to use the method of ratio and proportion
40:60
16:x
x= 16 x 60 / 40 = 24 minutes
So, he has 60-24 minutes to return home, that is 36
What is his speed if his time is 36 minutes= 0.6 hours
Speed = Distance divided by time = 16/0.6 = 26.6 miles per hour.
Hope this helps
Good Luck
