4 significant figures.
we can start counting the numbers after all the zeros in front. the zeros in front doesn't count in. but the zeros after the first number that is 1 or larger counts.
therefore we only need to look at 3010

Answer:
Step-by-step explanation:
Given that:
all coins are same;
The same implies that the number of the non-negative integral solution of the equation:


Thus, the number of the non-negative integral solution is:

(b)
Here all coins are distinct.
So; the number of distribution appears to be an equal number of ways in arranging 35 different objects as well as 5 - 1 - 4 identical objects
i.e.


(c)
Here; provided that the coins are the same and each grandchild gets the same.
Then;




Thus, each child will get 7 coins
(d)
Here; we need to divide the 35 coins into 5 groups, this process will be followed by distributing the coin.
The number of ways to group them into 5 groups = 
Now, distributing them, we have:

Answer:
x=5
Step-by-step explanation:
-3x+7=-8
Bring 7 to the other side, it becomes negative
-3x=-8-7
Signs are same on rhs so u add
-3x = -8+-7= -15
Bring -3 to the other side n divide
therefore,
x=-15/-3
= +5 (two negatives become positive)
Hope it helps!
