Length of largest piece is 4× 3.43 = 13.72 feet.
Step-by-step explanation:
Let the length of smallest piece be x
According to question, the middle piece is twice the length of the smallest piece.
So, length of middle piece be 2x
According to question, the largest piece is twice the length of the middle piece.
So, length of largest piece be 2(2x)=4x
Total length of pipe = 24 ft
So, it becomes,
Length of smallest piece is 3.43 feet.
Length of middle piece is 2× 3.43 = 6.86 feet
Length of largest piece is 4× 3.43 = 13.72 feet
Answer:
8.94 if no rounding is necessary.
Step-by-step explanation:
Pythagorean Theorem. What we know is only one leg and the hypotenuse, sooo...
8² + b² = 12²
64 + b² = 144
Subtract 64 from both sides...
64 - 64 + b² = 144 - 64
b² = 80
= 8.94 if you're not rounding.
