Ahostel having strength of 300 students requires on an average 36000 l of water per day. it has a tank measuring 10 m × 8 m × 9 m. for how many days will the water in the tank filled to capacity last?

The water in the tank filled to capacity lasts 20 days.

Step-by-step explanation:

Total number of students in the hostel = 300

The average need of water  per day = 36,000 L

The dimensions of the tank =   10 m  ×   8 m   ×   9 m

Now, the capacity of the tank = LENGTH X WIGHT X HEIGHT

     = 10 m   ×   8 m   ×   9 m =  720 cubic meters

Now,

⇒

So, the capacity of the tank = 720,000 L

and the average usage of water by 300 students =

⇒

or, number of days = 20

Hence,  the water in the tank filled to capacity lasts 20 days.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
