Answer:
39,960 is divisible by all of the listed numbers.
Step-by-step explanation:
The sum of digits is 3+9+9+6+0 = 27, and the sum of those digits is 2+7=9.
This tells you the number is divisible by 3 and 9.
The number is even and ends in 0. Together with divisibility by 3, this tells you the number is divisible by 6. The 0-ending tells you the number is divisible by 2 and 5 and 10.
The last two digits are 60, a number that is divisible by 4, so the number is divisible by 4.
39,960 is divisible by all of the numbers listed: 2, 3, 4, 5, 6, 9, 10.
In order to solve this we need to know the quantity of the 18 inch pizza eaten and the fraction of the minute in which it was eaten.
Answer:
B = 31, C = 11
Step-by-step explanation:
Let B be the number of Black printer ink cartridges and C be the number of color printer ink cartridges.
42 were sold in total, hence,
B+C= 42 ------------(1)
Also, its given that
14.99 B+20.99C= 695.58 ------(2)
Multiplying (1) by 20.99,
14.99 B+14.99 C= 629.58 ------(3)
Now, subtracting (3) from (2),
14.99 B+20.99C= 695.58
14.99 B+14.99 C= 629.58
------------------------------------
6 C = 66
C= 66/6
C = 11
We know, B+ C= 49
Hence B = 42- 11 = 31
B = 31
Hence, number of Black printer ink cartridges = 31 and color printer ink cartridges = 11 .
