Answer:
a) To find the other missing length we must be given an area and a length
We then divide the total area by the given length
so
6534/99 = 66 is the missing width
2.356194 I think that’s what the answer is
The nearest ten is 400 and the hundred is 300
I think a is (8,-8)
B) (0,8)
If your number is quite large, like 3 digit or higher than that, then calculate the sum of their digits, if they will be divisible by 3, then the number is divisible, otherwise not.
For example. - "11055"
Here, sum of digits = 1 + 1 + 0 + 5 + 5 = 12
As 12/3 = 4 (Divisible)
In short, This number would be divisible.
Hope this helps!
