Given:
All the edges of a cube are expanding at a rate of 4 in. per second.
To find:
The rate of change in volume when each edge is 10 in. long.
Solution:
Let a be the edge of the cube.
According to the question, we get
We know that, volume of a cube is
Differentiate with respect to t.
Putting the given values, we get
Therefore, the rate of change in volume 1200 cubic inches per second.
Answer:
300 Adults 555 Children
Step-by-step explanation:
What we know:
Firstly, at 5pm there were 36 more Children (C) than Adults (A)
So.....C = A + 36
Secondly, at 12pm there were 5 x more Children and 4 x more Adults and the total was 855
So 4A + 5C = 855
——-
Now use ‘C = A + 36’ and get rid of all ‘C’ in the second equation.....
4A + 5C = 855
becomes......
4A + 5 (A + 36) = 855
Multiply the brackets (5 x A) and (5 x 36):
4A + 5A + 180 = 855
Take off 180 from both sides:
4A + 5A = 675
Therefore 9A = 675
Divide by 9:
A = 75
We know C is A + 36
C = 111
At 5 pm - A = 75 and C = 111
Therefore at 12:
There were 5 x C = 555
And 4 x A = 300
