Ruth began filing an empty water tank at a constant rate of 3 hours the tank has 147 times pi, m^3 liters of water. Approximately what percent of the tank would be full of water after 9 hours.

5.8%

Step-by-step explanation:

Proportions

If we know the constant rate at which a quantity is changing over time, we can set an equation to model the current quantity as a function of time.

We know Ruth began filling an empty water tank at a constant rate of 3 per hour (assuming that unit, not specified in the question).

The tank has a capacity of of water, thus at 9 hours, it has been filled with of water.

To compute the percentage of filling, we compare this volume with the total capacity of the tank

u what ?

step-by-step explanation:

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
