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.
The slope is -3 and the y-intercept is -1
If line r is parallel to line q, they have the same slope which is -2. You can use the point-slope formula <span>y-y₁=m(x-x₁) and plug in 8 for y and -8 for x. Solve for y to get the equation in slope-intercept form (y = mx + b). "M" is the slope.</span>
Answer:
9
Step-by-step explanation:
All you have to do is subtract the temperatures once you get the final answer for them.
4 days, -7°C, = 43<em>°C</em>
5 days, -6°C, = 34<em>°C</em>
<em>43 - 34 = 9</em>
<em>9°C</em> = 9

You start from 0 and then you go to the left 2 units and then 3 down the y axis.
