If you add all of the digits of a number, and it's divisible by 3, the entire number will be divisible by 3.
If the number is divisible by 2 and 3, it's divisible by 6 as well.
If the digits of a number add up to a number divisible by 9, the whole number will be divisible by 9.
Answer:
The growth rate he needs to achieve his goal is approximatelly 19.8%
Step-by-step explanation:
Since the sum will be compounded continuously we have to use the appropriate formula given below:
M = C*e^(r*t)
Where "M" is the final amount, C is the initial amount, r is the interest rate and t is the time elapsed. Since Sung Lee will invest that sum at 18 years old and he wants to recieve the return at 25, then the time elapsed is given by 25 -18 = 7 years. We can now apply the data to the formula:
16000 = 4000*e^(r*7)
4000*e^(7*r) = 16000
e^(7*r) = 16000/4000 = 4
ln[e^(7*r)] = ln(4)
7*r = ln(4)
r = ln(4)/7 = 0.198
The rate of interest is given by (r)*100%, so we have (0.198)*100% = 19.8%.
Answer: 59.04
Step-by-step explanation:
tan 16= x/200
tan16/1=x/200
200 tan 16=x
x=57.349077...
x=57.349077...
Add 1.69, the distance from the ground to her eye:
57.349077...+1.69=
59.039077...
≈ The skyscraper is 59.04 meters tall.
Answer:
The answer to your question is: x = - 14
Step-by-step explanation:
Solve 4 + x/7 = 2
Multiply by 7 7(4 + x/7 = 2)
expand 28 + x = 14
simplify x = 14 - 28
result x = - 14
Answer:
E. 0.23
Step-by-step explanation:
given that you are looking for a great person to spend your life with.
The prior probability that someone is a great matchi.e. event A is 0.1
Their probability of having a good job is 0.8,i.e. P(B/A)
whereas 30% of people who are not a great match also have a good job.
P(B/A')
On the first date you learn that the person has a good job.
Required probability = the probability that they are a great match/the person has a good job
=P(A/B) =
since A and A' are mutually exclusive and exhaustive.
=
After rounding off we find that
answre is option E) 0.23
