Answer:

t2 = 52.8 hours

it will take 52.8 hours if its flow is reduced to 5 litres per minute.

Step-by-step explanation:

The volume of the swimming pool can be written as;

Volume V = flow rate × time

V = R×t

V = R1×t1 = R2×t2

R1×t1 = R2×t2

t2 = R1×t1/R2 ........1

Given;

Flow rate R1 = 12 litres per minute

Flow rate R2 = 5 litres per minute

time t1 = 22 hours

Substituting the given values into equation 1;

t2 = R1×t1/R2 = 12×22/5

t2 = 52.8 hours

it will take 52.8 hours if its flow is reduced to 5 litres per minute.

Trevor plans on buying a car. Four banks offer the annual interest rates shown.
mote1985 [20]

Solution

In order to find  greatest to least number, we have to convert the given fractions into decimals.

3 \frac{1}{10} % = 3 + 1/10 = 3 + 0.10 = 3.10%

3 \frac{2}{5}% = 3 + 2/5 = 3 + 0.40 = 3.40%

3 \frac{1}{4} %= 3 + 0.25 = 3.25%

3 \frac{1}{3}% = 3 + 0.33 = 3.33%

Now we can easily, compare the numbers and write from greatest to least.

3.40%, 3.33%, 3.25%, 3.10%

Greatest to least  = 3 2/5%, 3 1/3%3, 3 1/4%,  1/10%,

Thank you :)
