We would need to use 4 pipes to be sure to empty the chamber within 10 hours time.
Work:
5*5/3*4/10=3 1/3 pipes (but we must round since we cant have 1/3 of a pipe running. This means that we must have 4 pipes.
In order to find out what the blank of your expression is,, we must solve for y. We can start doing this by distributing -2 through the parenthesis.
y - 4 = -2x - 6
Now you need to move the constant to the right side and change its sign.
y = -2x - 6 + 4
Calculate the sum of -6 + 4.
y = -2x - 2
Since we cannot simplify this down any further,, y is going to equal -2x - 2.
Let me know if you have any further questions.

The space between the two spheres will be the volume of the larger sphere minus the volume of the smaller sphere. Given that the volume of any sphere is:
V=(4πr^3)/3 The space between to sphere of different radius and positioned about the same center is:
S=(4πR^3)/3-(4πr^3)/3 I used S=volume of space, R=larger radius and r=smaller radius...
S=(4π/3)(R^3-r^3), we are told that R=5 and r=4 so
S=(4π/3)(5^3-4^3)
S=(4π/3)(125-64)
S=(4π/3)(61)
S=244π/61
S=4π cm^3
S≈12.57 cm^3 (to nearest hundredth of a ml)
