The answer is 24. . The key to this answer is in the wording of the question - there are four different flavors of ice cream on the cone - meaning no flavor can appear more than once on the cone. . :-)

There are 4 possibilites for the top, 3 for the seod, two for the third and 1 for the last. that makes 4*3*2*1=24 possibilites.

3(2x + 4) -  2x   =  50

6x  +  12   - 2x   = 50

4x  + 12  = 50      subtract   12  from both sides

4x  = 38      divide both sides by  4

x  = 38/4 = 19/2  =   9. 5

The website you showed me has the chocolate on the bottom part while this one does not. Thanks, though!

Simplifying we get 6x+12-2x=50. Further we get 4x+12=50. SUbtract 12 on each side. 4x=38. x=9.5

x=18

Nice job!

since all even numbers (2,4,6) will come is the last position, it can be filled in 3 ways, then the first place can be filled by 3 odd numbers + 2 even numbers (since one even number is fixed in the last position), the second position can be filled by 4 digits + 0 that is 5 digits, the third place can be filled by 4 digits and last place by 3, 

best answer plz I need it 

Thanks!

There are 4 possibilities for the first digit and 4 possibilities for the second. 4*4=16

Thanks! You guys rock!

P.S. 1 one was the answer

1 is the first odd natural number. An odd number will be never found in the unit's place for even number. So the lowest single-digit odd is 1 and will never be in the unit's place for even number.

best answer plz

1. All even numbers end in either a 0, 2, 4, 6 or 8. so we have 1,3 ,5 ,7 and 9. One is the smallest of those.

0, because 0 is the smallest number never found in an EVEN NUMBER.

Nice job! Thanks!

7 is the unit digit :) best answer

THANKS! I needed the explanation.

22.5 and 67.5

From 5! and beyond, the units digit is always 0 since there is always a multiple of five in there. SO we only have to focus on 1! and 3!. 1! is 1, and 3!=3*2=6. 6+1=7.

7 is the units digit.

where are you getting this?

THX!

The numbers through 1-10 that are not divisible by 10 are 2, 3, 4, 6, 7, 8 and 9(the one doesn't matter.) Multiplying, we get 72576, so the units digit is 6.
