Forgive me if im wrong but its what I choose on the exam
Hi there!
#1 Washing you’re hands after touching anything that may be dirty, or even just using the restroom.
#2 Disinfecting door nobs, handles, desks and things you may touch on a daily basis.
#3 Stay away from those you may think are sick.
#4 Having those around you remember to cover their mouths and noses while sneezing.
Remember to do this using the pit of you’re elbows NOT you’re hands. This can spread germs more easily.
Hope this helps you!
Answer:
There are 64 fish, 8 ducks and 4 turtles.
Explanation:
From the question, there can be from 2 to 99 fish in the pond. However, there cannot be fractions in the number of fish, ducks or turtles. Hence, the number of fish must have both of a perfect square and perfect cube. The perfect squares from 2 to 99 are 4, 9, 16, 25, 36, 49, 64 and 81. The perfect cubes from 2 to 99 are 8, 27 and 64. Since only 64 fits both criteria, the number of fish is 64. The number of ducks is the square root of number of fish, which is the square root of 64. The square root of 64 can be either positive 8 or negative 8. However, there cannot be negative numbers, so there are 8 ducks in total. The number of turtles is the cube root of the number of fish, which is the cube root of 64 and it is 4.
