Answer:
its going well hbu
have a good day :)
Step-by-step explanation:
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.
Answer:
3
Step-by-step explanation:
B2,4 : 9
B3,2 : 6
9 - 6 = 3
Step-by-step explanation:
Original height is the initial value, burn down rate is 0.5 inches per hour
<u>This would be represented by a function:</u>
<h3>Part A</h3>
<u>Ordered pairs:</u>
- (0, 9), (1, 8.5), (2, 8), (3, 7.5), (4, 7), (5, 6.5), (6, 6)
<h3>Part B</h3>
- Rate of burn down is stable at 0.5 inches, this is a function
<h3>Part C</h3>
If the rate at which the candle burned was 0.45 inches per hour instead of 0.5 inches per hour, the relation would still be a function. The output values would have same difference of 0.45 inches and the function would be:
