The 6-digit number 789ABC is divisible by 7, 8, and 9, and all of its digits are distinct. What is the 3-digit number ABC?

264

Step-by-step explanation:

This is the answer because:

1) You have to know the divisibility rules of 7, 8, and 9:

2) Since 7+8+9 equals to 24, the last three digits have to add up to 24 to make 36 (divisible by 9).

3) The number also has to divisible by 7 and 8.

4) 264 adds up to 36 (the digits: 2,4, and 6), the number is divisible by 8, and finally, 789264 is divisible by 7.

Therefore, ABC = 264

Hope this helps! :)

ABC = 264.

Step-by-step explanation:

The number is divisible by 7*8*9 = 504.

504 * 1500 = 756000

Lets try a larger value:

`504 * 1580

= 796320

So we are close to the number required and the multiplier must be less than 1580.

504 * 1570 = 791280

504 * 1567 = 789768

We are close - the first 3 numbers are correct but it's not this one as some of last 3 digits are duplicated.

504 * 1566 = 789264 - That's the one

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
