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)

Step-by-step explanation:
Answer: 565.48
Step-by-step explanation:
Lets calculate areas:
single area = (78)(27) = 2106 ft^2
doubles area = (78)(27 + 9) = (78)(36) = 2808<span> ft^2</span>
junior area = (36)(18) = 648 ft^2
10&under area = (78 - 18)(27) = (60)(27) = 1620 <span>ft^2
</span>
The doubles area is bigger than the singles by 2808 - <span>2106 = 702 ft^2</span>
The singles area is bigger than the juniors by 2106 - 648 = 1458 <span>ft^2
</span>The singles area is bigger than the 10&under by 2106 - 1620 = 486 <span>ft^2</span>
