Answer:
9 cm.
Step-by-step explanation:
Let the height of the pyramid be h cm, then the height of the cuboid is (15 - h) cm.
Volume of the pyramid:
= 1/3 * h * s^2 where s is the length of a side of the square base.
= hs^2/3 cm^3
Volume of the cuboid:
= s^2(15 - h).
So we have:
hs^2/ 3 = 300.......................(1)
s^2(15 - h) = 600..................(2)
From equation (1) :
h s^2 = 900
s^2 = 900/h
Now substitute for s^2 in equation (2) :
(900/h)(15 - h) = 600
Multiply through by h:
900(15 - h) = 600h
13500 - 900h = 600h
1500h = 13500
h = 9 cm (answer). brainliest?

Answer:
The total calories in the food is 50.
Step-by-step explanation:
Given,
Calories coming from fat = 20
In percentile calories coming from fat = 40%
Solution,
Let the total calories in the food be 'x'.
And given that 40% of the total calories are coming from fat, which is 20.
That means x multiplied with 40% is equal to 20.
So framing the above sentence in equation form, we get;
Now we have to remove the percentile.
For this we have to divide 40 by 100, then we get;
Multiplying by 100 on both side, we get;
Hence The total calories in the food is 50.

Step-by-step explanation:
404 Error it occurs when a question is INPROPER like if it is not related to subjects it will be get deleted.
Then if a question is INCOMPLETE it will be deleted mostly it will be deleted in asking question paper this sorts of one because While asking a question paper one mention all detail like which class which board for which exam you needed question paper.
