A garden is 12 yards long. assuming the snail moves at a constant speed, how many minutes does it take the snail to travel the l
ength of the garden? Speed: 5^(-5)feet per second
1 answer:
15 minutes, first you need to convert everything to feet, 3yards in a foot so multiply 12 by 3 and you get 36ft, 5^-2 is 0.04, so the snail goes 0.04ft every second. Divide 36 by 0.04 to get 900, that’s the distance and if he moves like that every second then that’s also the time, divide 900 by 60 to get minutes.

Given:
The sets are and
.
To find:
Whether A and B are disjoint sets or not.
Solution:
Two sets are called disjoint sets if there are no common elements between them.
We have,
Clearly, there is not common elements between the set A and set B.
Therefore, the sets A and B are disjoint sets.
