Answer:
B. 72
Step-by-step explanation:
The rule of 72 is used as a rough estimate of the number of years required for an investment to double.
According to this rule, the number of years 'n' necessary to double an investment at an annual rate 'r' is:
![n=\frac{72}{r}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B72%7D%7Br%7D)
Therefore, the number that when divided by the interest rate gives the number of years required to double an investment is 72.
The answer is B. 72.

Answer:
B
Step-by-step explanation:
A triple a, b, c is a Pythagorean triple if
![a^2+b^2=c^2.](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2.)
Check all options:
A.
![2^2+3^2=4+9=13\neq 6^2.](https://tex.z-dn.net/?f=2%5E2%2B3%5E2%3D4%2B9%3D13%5Cneq%206%5E2.)
B.
![3^2+4^2=9+16=25=5^2.](https://tex.z-dn.net/?f=3%5E2%2B4%5E2%3D9%2B16%3D25%3D5%5E2.)
C.
![4^2+5^2=16+25=41\neq 9^2.](https://tex.z-dn.net/?f=4%5E2%2B5%5E2%3D16%2B25%3D41%5Cneq%209%5E2.)
D.
![5^7^2=25+49=74\neq 12^2.](https://tex.z-dn.net/?f=5%5E7%5E2%3D25%2B49%3D74%5Cneq%2012%5E2.)

Answer:
5, 13, 10, 8
Step-by-step explanation:
hello, so for this question keep in mind the triangle inequality theorem which states- a side must be smaller than the sum of the other two sides.
go through each of the choices.
a. 5+7=12 12>9
b.2+7=9 9>9 this cant be the answer since 9 is equal to nine, not greater than,
c. 13+7=20 20>9
d.10+7=17 17>9
e.8+7=15 15>9
f.22+7=29 29>9 although 29 is greater than 9, we also have to keep in mind that the other 2 sides must also be greater than the other side. so try 7+9= 16. 16 isnt greater than 22 so it can’t be one of the answers.
hope this helped :)
