Answer:
0, 1, 4, 5, 6, and 9 can be the last digits of the squares of natural numbers.
Step-by-step explanation:
When looking at a list of the perfect squares, the last digits continuously follow this pattern: 1, 4, 9, 6, 5, 6, 9, 4, 1, 0. After this it repeats. This means that these are the only numbers that can be the last digits. When you take out the repeated numbers you get: 1, 4, 5, 6, 9, 0 which when written in order is:
0, 1, 4, 5, 6, and 9
Answer:
Step-by-step explanation:
Ron and Pam each have 20 pennies.
Ron will put his pennies into 4 groups.
In each group of Ron the number of pennies =
= 5 pennies
Pam will put her pennies into 5 groups.
In each group of Pam the number of pennies =
= 4 pennies
Ron will have 5 pennies in each group and Pam will have 4 pennies in each group, because Ron will make less groups of pennies than Pam.
Hence Ron will have more pennies in each group than Pam.
temperatures x in January?
Answer:
x≥7°F
Step-by-step explanation:
This is because 7°F is the lowest temperature and so all other temperatures of the day were greater than that one.
Answer: 45
Step-by-step explanation:
Given: The total number of lettered tiles in a board game =105
The number of tiles chosen (R, A, I, L, M, B, E) = 7
the number of vowels chosen (A,I,E)=3
Now, the fraction or probability of choosing of vowels out of 7 given letters is given by :-
Now, the number of vowels we can expect to be vowels out of 105 letters is given by :-
Hence, the number of vowels we can expect to be vowels out of 105 letters is 45.
