Answer:
3.04m
Step-by-step explanation:
Time taken to swing the rope = 3.5s
Length of the rope = L
T = 2π√(L / 9.8)
3.5 = 2π√(L / 9.8)
take the square of both sides
(3.5)² =[2π√(L/9.8)]²
12.25 = 39.48 × (L / 9.8)
12.25 = 39.48L / 9.8
39.48L = 12.25 × 9.8
39.48L = 120.05
L = 120.05 / 39.48
L = 3.04m
The length of the rope is 3.04m

Step-by-step explanation:
Answer: 3 x n -10 = n + 4
Step-by-step explanation:
n is your number,
3 times a number is 3 x n;
10 less than 3 times a number is 3 x n - 10
same means equality, we will use "="sign
3 x n - 10 = ...
n is your number
number plus 4 is (n + 4) --->
final expression is:
3 x n - 10 = n + 4
