Answer:
We conclude that its value change for 277.8$.
Step-by-step explanation:
We know that a perpetuity pays $50 per year and interest rates are 9 percent. We calculate how much would its value change if interest rates decreased to 6 percent. We know that
9%=0.09
6%=0.06
We get
\frac{50}{0.09}=555.5
\frac{50}{0.06}=833.3
Therefore, we get 833.3-555.5=277.8
We conclude that its value change for 277.8$.
The length of the shortest piece is 5cm.
Given that the length of the board = 62cm
Let the length of the first piece be x cm.
Hence, according to the question,
Length of the second piece = 2x cm
Length of the third piece = (2x + 7) cm
We have to find the length of the shortest piece.
Hence, we can write,
62 = x + 2x + (2x + 7)
62 = 5x + 7
5x = 62 - 7 =55
x = 55/11 = 5 cm
Hence, the shortest side is the first side of 5 cm.
