Position in the sequence triangular number relation
1 1 1 = 1*(1+1)/2
2 3 3 = 2(2+1)/2
3 6 6 = 3(3+1)/2
4 10 10 = 4(4+1)/2
5 15 15= 5(5+1)/2
Call n the position in the sequence, then the triangular number is: n(n+1)/2
Volume of the wrapper = pi * 0.7^2 * 10 = 4.9pi cm^2
Volume of one tablet = 0.7^2 * 0.5 pi = 0.245pi
Number of tablets in the wrappe = 4.9pi / 0.245pi = 20 (answer)
The fifth root of 32 is 2
In other words,
![\sqrt[5]{32} = 2](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B32%7D%20%3D%202)
It's similar to stating that 7^2 = 49 can be transformed into saying sqrt(49) = 7 where "sqrt" is shorthand for "square root"
The general rule is
![x^n = b \ \ \longleftrightarrow \ \ \sqrt[n]{b} = x](https://tex.z-dn.net/?f=x%5En%20%3D%20b%20%5C%20%5C%20%20%5Clongleftrightarrow%20%5C%20%5C%20%20%5Csqrt%5Bn%5D%7Bb%7D%20%3D%20x)
Answer:
24
Step-by-step explanation:
Your max is 49 and your min is 25; 49-25 = 24
