Answer: C 2.5%
Step-by-step explanation:
The "Rule of 72" is a easy way to calculate how much time an investment will take to double with a given fixed annual rate of interest.
Just we have to divide 72 by the annual rate of return(r), we can get a rough estimate of how many years it will take to double the initial investment .
Now, in given problem: Let 'r' be the rate of interest
Time to double the amount=29 years
Thus by rule 72 ,

Therefore, C is the right option.
Answer:

The answer must be

since the triangular pyramid has 4 faces and each has an area of 30

we should multiply that by 4 , so :
Answer:
p(a) = -3/20
Step-by-step explanation:
p ( a +b) = p(a)+p(b)
1/10= p(a) +1/4
1/10 - 1/4 = p(a)
p(a) = -3/20
