A string is 148 cm long. It is cut into 3 pieces. The longest piece is 4 times as long as the middle sized piece and the shortest piece is 77 cm shorter than the longest piece. Find the length of the shortest piece (in cm).
23 cm . Lets set the middle string at length x. The longest string is then 4 * x. The shortest string is then 4 * x - 77. The total string = 148 = 4 * x + x + 4 * x - 77 = 9 * x - 77 x = (148 + 77) / 9 = 25. The shortest string is 4 * 25 - 77 = 23 cm.
A rope is 89 cm long. It is cut into 3 pieces. The longest piece is 3 times as long as the middle-sized piece and the shortest piece is 44 cm shorter than the longest piece. Find the length of the shortest piece (in cm).
A string is 94 cm long. It is cut into 3 pieces. The longest piece is 4 times as long as the middle sized piece and the shortest piece is 59 cm shorter than the longest piece. Find the length of the shortest piece (in cm).
Aanya had 20.80 m of cotton piece. She cut 7 smaller pieces, each of length 0.81 m from it. How many meters of cotton ( approx) were left?
I have a stick of length 3 cm and I select 2 random points on it and break it at those points to get 3 pieces.
If the probability that these pieces will form a triangle is m/n where m and n are coprime integers then what is the value of m × n?
