Answer:
126
Step-by-step explanation:
Total volume of sand = pi/3*(6^2)*(15) + pi*(6)^2*(30) = 1260*pi mm^3
So it will therefore take 1260*pi/10*pi = 126 seconds for all of the sand from the top hourglass to drip down to the bottom hourglass.
Answer:
y^3 + 5y + 8
Step-by-step explanation:
Collect like terms
4y^3 - 3y^3 + 2y + 2y + y + 4 + 4
= 1y^3 + 5y + 8 OR y^3 + 5y + 8

Answer:
x = 8
Step-by-step explanation:
3(x-5)+6x = 3x-15+7x
