A water trough is in the shape of a prism. 30 cm
20 cm
120 cm
20 cm
40 cm
40 cm
80 cm
Hamish fills the trough completely.
Water leaks from the bottom of the trough at a constant rate.
2 hours later, the level of the water has fallen by 20 cm.
Water continues to leak from the trough at the same rate.
How many more minutes will it take for the trough to empty completely?

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
