Answer: 9 L
Step-by-step explanation:
Given
The dimension of the rectangular container is 
It is filled with 
of the height
Water present in the container
Also, 
Now, half of the water is poured out
So, half is left
Thus, 9 L of water is left in the container
I think the answer ia A that what i think
OB. The digits in the millions period are 41, the digits in the thousands period are 000, and the digits in the ones period are 138.
The digits of a number can be classified into into 3 groups and each such group is called a period.
Here, we are give a number 41,000,138.
In this number, the million period consists of
ten millions - 4
and millions - 1
Hence the digits in the million periods are 41
The thousand period consists of all zeroes, hence the digits in thousand periods are 000.
The ones period contains-
hundreds - 1
tens - 3
and ones - 8
Thus, the digits in the ones period are 138
Hence, option B is the correct answer.

Ok, so I'll make an example problem to show.
There's a forest in town and it's recorded that there are 5 bears and 100 squirrels in it.
First, you would make this a ratio so that would be 5:100. 5 being the bears and 100 being the squirrels.
To simplify it, just make it into a fraction. The first number, going from left to right, would be the numerator and 100 would be the denominator.
5
-----
100
To simplify, just divide by the greatest common factor which would be 5 in this case.
5 1
----- / 5 = ----
100 20
Answer:
2x^2 + 100x +800
1350 ft^2
Step-by-step explanation:
The length of the pool and walkway is x+40
The width of the pool and walkway is x +20+x = 2x+20
Area is length times width
A = (x+40) *(2x+20)
We can FOIL to find the area
first x*2x = 2x^2
outer x*20 =20x
inner 2x*40 = 80x
last = 40*20 = 800
Add these together
2x^2 +20x+80x+800
2x^2+100x+800
b. x=5
2x^2 + 100x +800
2(5)^2 +100(5) +80
2*25 +500+800
50+1300
1350 ft^2
