Answer:
It should be the third bubble, because all integers are whole numbers
The solution would be like this for this specific problem:
Volume of a cylinder = pi * r^2 * h
Volume of a cone = 1/3 * pi * r^2 * h
Total Height = 47
Height of the cone = 12
Height of the cylinder = 35
If the top half is filled with sand, then:
volume (sand) = pi * 4^2 * 36
volume (cone) = 1/3 * pi * 4^2 * 12
Total volume = 1960.353816 cubic millimeters
353816 / (10 * pi) = 62.4 seconds.
It will take 62.4 seconds until all of the sand has dripped to the bottom of the hourglass.

<span>two consecutive even integers are x and x + 2
3(x + 2) - x = 42
3x + 6 -x = 42
2x = 36
x = 18
answer
smaller number: 18
bigger number: 18 + 2 = 20

For Nina: 117.60 / 1414 = 0.083168317 For Ty: 148.50 / 1818 = 0.081683168 For Kim: 137.60 / 1616 = 0.085148515 Then Kim has the highest pay rate in dollars per hour with a total of 0.085148515 $ / h.
