In this question a simple task is required to be done and that is increase 160 km by 30%
Then
Amount of increase in km = 160 * (30/100)
= 48 km
Then the km after increase = (160 + 48)
= 208 km.
In this problem the only thing that needs to be done
correctly is the calculation. Otherwise there is nothing tough in this problem.
I hope it helps you to understand the procedure for solving the problem.

Answer:
Tn=12n(n+1)
Step-by-step explanation:
Explanation:
These are the triangular numbers - each term in the sequence being the sum of the first n positive integers:
T1=1=1
T2=3=1+2
T3=6=1+2+3
etc.
Notice that:
2Tn=(0)+1+(0)+2+...+(n−1)+(0)+n
2Tn+(0)+n+(n−1)+...+(0)+2+(0)+1
2Tn=(n+1)+(n+1)+...+(n+1)+(n+1)
2Tn=n(n+1)
So:
Tn=12n(n+1)
Answer:
1.91 Ohms
Step-by-step explanation:
It is given that the resistance of the conductor is 3.18 Ohms/1000 feet.
It means that the resistance of the 1000-foot conductor is 3.18 Ohms.
So, the resistance of the 600-foot #12 (solid) aluminium conductor is
= 6 × 0.318
= 1.908
= 1.91 Ohms (rounded to two decimal places)
