Answer:
It will take 30 days to reach the top of the 30-foot deep pipe.
Step-by-step explanation:
Let's track Sam Snail's movement each day:
Day 1 -
0 + 3 - 2 = 1
Day 2 -
1 + 3 - 2 = 2
Day 3 -
2 + 3 - 2 = 3
Day 4 -
3 + 3 - 2 = 4
Day ...
We can see that the day always matches up with the height on the pipe. This means for the snail to have traveled 30 feet, he needs to have spent 30 days with a constant rate of movement.
Hope this helps!
Answer:
44
Step-by-step explanation:
Given that Avi used 11 toothpicks to form a row of 5 attached triangles.
Total number of toothpicks used = 89
Let the total number of triangles formed be represented by x, so that:
11 toothpicks = 5 triangles
It would be observed that only the first triangle starting the pattern has 3 toothpicks. So that;
the average number of toothpicks for 1 triangle = 
= 2.2
The number of toothpicks per triangle = 2.0
Thus,
x = 
= 44.5
x = 44
The total number of triangles formed is 44.
