Answer:
When there are 108 presents, there are 60 candy canes
Step-by-step explanation:
candy canes : presents = 5:9
5/9 = x/108
cross multiply:
(5) (108) = 9x
540 = 9x, divide both sides by 9
x = 60
14.7 mm is the height.
Use the volume equation for a cylinder which is
volume=(PI/4)*(diameter^2)*(height)
And you have volume, and diameter (which is just radius times 2) so solve for height.
5588=(PI/4)*(22^2)*Height
Height = 14.7 mm
Take the average, which always lies in the middle of any two numbers:
(1413/5689 + 1838/7370) / 2 = 5217548/20963965
To get another number, take the average of this number with any of the first two. For example,
(1413/5689 + 5217548/20963965)/2 = 10424453/41927930
Notice that
1413/5689 ≈ 0.248<u>374</u>
10424453/41927930 ≈ 0.248<u>628</u> … … … (the second average, between the first number and the first average)
5217548/20963965 ≈ 0.248<u>882</u> … … … (the first average of the given two numbers)
1838/7370 ≈ 0.24<u>9389</u>
