The left side of the equal sign is exactly the same as the right side, so it has infinitely many solutions.
Unit price = price for one donut
if 12 donuts cost $8.50, then one donut would be:
$8.50/12 = 0.7083, or about $0.71
Answer:
Hey there!
1) To solve this, we want to know the volume of the first cylinder, which using the cylinder volume formula, we find is roughly 3079 cm^3. If the water is poured into the second cylinder, we find that the height is about 9.8 cm.
2) First, we should know that 1000 cm^3=1 liter. Volume of 1 cm tank height: 3848 cm^3, or 3.848 l. Volume for 20 cm tank height= 76.96 l. It takes about 7.7 hrs for the water level to fall 20 cm.
3) Cylinder volume formula gives us the answer to be 176 m^3 as the volume.
Hope this helps :)
