Answer:
36.23 kilograms of roasted beef
Step-by-step explanation:
If deli sliced 13.7 kilograms (kg) of roasted beef one week
He sliced 22.53 kilograms (kg) the next week
Total sliced kilograms of roasted beef=13.7 kg + 22.53 kg
=36.23 kg
The deli sliced a total of 36.23 kilograms of roasted beef in the two weeks.
The distance to the store is
.. (0.3 h)*(10 mi/h) = 3 mi
The time home is
.. (3 mi)/(30 mi/h) = 0.1 h
The average speed is the total distance divided by the total time
.. speed = (3 mi +3 mi)/(0.3 h +0.1 h) = (6 mi)/(0.4 h) = 15 mi/h
Ishaan's average speed was 15 mi/h.
Answer:
22
Step-by-step explanation:
Remark
Very nice little problem.
At first you think you need to go through the entire number system from 1 to 500. For example, you could do 12 as 1 2 3 4 6 12 So 12 does not add to the number of integers that have an odd number of factors.
But along the way if you check all the factors of the integers from 1 to 12, you notice something very odd. (No pun intended).
1 only has 1 factor which is odd (not even).
4 has 3 factors 1 2 4 which is odd.
9 has 3 factors 1 3 9 which is odd.
It turns out that there are 22 numbers from 1 to 500 that have an odd number of factors. They are the perfect squares between 1 and 500
Note
The factors of an integer include 1 and the integer itself
As a conclusion, try 36
1 2 3 4 6 9 12 18 36 There's 9 factors which is odd. So only the perfect squares have an odd number of factors.
