Type a digit that makes this statement true.<br> 7,176,260 is divisible by 3.<br> Submit
Margarita [4]

Answer:

1, 4 or 7

Step-by-step explanation:

The divisibility rule/shortcut for 3 is that the sum of its digits is divisible by 3. So, you currently have 29 (7+1+7+6+2+6+0), and you have to make that number divisible by 3.

adding 1 gets you 30, which we know is divisible by 3.

then, instead of trying every digit, we can note that

30 , 33 , 36 , 39 ....

are divisible by 3.

But the most we can add to the sum of 29 is 9 (because that is the highest digit possible)--so numbers above 38 are irrelevant

so, we want to find out if we can make 29 into 30, 33, or 36

adding 1 to 29 = 30

adding 4 to 29 = 33

adding 7 to 29 = 36

So, by making the first digit 1 , 4 , or 7, you make the number divisible by 3 (making the sentence true)

so you would multiply the dimensions of the tower by 50 get the actual dimensions.

height: 2.25 ft x 50 = 112.50 feet high = 113 feet ( rounded)

width: 1.25 x 50 = 62.5 feet wide = 63 feet (rounded)
