What is the smallest multiple of 18 of the form 2A945B, where A and B are digits?

musickatia [10]

Answer:

$219456$

Step-by-step explanation:

It must end in $0,2,4,6,8$ (divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).

The digit sum is $2+A+9+4+5+B=20+A+B$ .

We want to make $A$ as low as possible because it's a higher digit than $B$ .

If $A$ is as low as possible, we have that the sum is $20+0+7=27$ . Uh-oh. $B$ has to be even! So $A=0$ doesn't work.

If $A=1$ , we have that the sum is $20+1+6=27$ . Yay!

So, the answer is $\boxed{219456}$

A n-faced regular polyhedron consists of 2n edges and (2n-4) vertices. Find n .

ira [324]

We could use Euler's polyhedron formula:

$F=n\qquad\qquad\text{(Faces)}\\\\E=2n\qquad\qquad\text{(Edges)}\\\\V=2n-4\qquad\qquad\text{(Vertices)}\\\\\\V-E+F=2\\\\2n-4-2n+n=2\\\\-4+n=2\qquad|+4\\\\\boxed{n=6}$

PilotLPTM [1.2K]

Answer:

$9C6 / 25C6$ = 84/177100

Step-by-step explanation:

Here 9 mid sized

16 compact cars

selected = 6

$9C6 / 25C6$ = 84/177100

for 3 mid sized

3 compact cars

then

3Cx/9Cx

divide by 3 we get

Cx/3Cxtaking Cx coomon

it become Cx =1/3 hence the probability is 1/3
