Answer:
The answer to your question is shortest ladder = 6 ft, middle ladder = 12 ft, longest ladder = 24 ft.
Step-by-step explanation:
Data
Ladder 1 = x/2
Ladder 2 = x
Ladder 3 = 2x
Total length = 42 ft
Process
1.- Sum the length of all ladders and solve for x
x/2 + x + 2x = 42
Least common factor = 2
(x + 2x + 4x)/2 = 42
Simplify
7x/2 = 42
7x = 42(2)
7x = 84
x = 84/7
x = 12
2.- Find the length of the ladders
Ladder 1 = 12/2 = 6
Ladder 2 = 12
Ladder 3 = 24

12 rows of 15 squares = 12 × 15 = 180 squares
5 rows of 8 squares = 5 × 8 = 40 squares
180 squares - 40 squares = 140 squares

X is the first number
Y is the second number
X+6 = 1/2Y
X+Y = 21
solving both equations will give you
X= 3 and Y =18
Answer:
About 90%
Step-by-step explanation:
If the cup was filled at a constant rate, then the cup fills at 70/2=35 cubic centimeters per second. The formula for the volume of a cone is , or in this case cubic centimeters. After 3 seconds, the cup would have 35*3=105 cubic centimeters of water inside of it, or about 89.52% which rounds to 90%. Hope this helps!
