Answer:

13.89%

Step-by-step explanation:

First you list the ways you can roll a die to get 6 and count how many combinations there are.

1 + 5

2 + 4

3 + 3

4 + 2

5 + 1

(5 Combinations)

Now you divide the number of desired outcomes (5) by the total number of outcomes (36)

5 ÷ 36 = 0.138888888888

Then you convert it to a percentage by moving the decimal over 2 times. Example: 13.88888888

Then I rounded it to the nearest hundredth. Ex: 13.89%.

Answer:

$\text{Average rate}=\frac{\text{40 laps}}{\text{ hour}}$

Step-by-step explanation:

Please consider the complete question.

Sebastian swan laps every day in the community swimming pool. He swam 45 minutes each day, 5 days each week, for 12 weeks. In that time, he swam 1800 laps. What was his average rate in laps per hour?

Let us convert time taken into hours as:

$\text{Days}=5\times 12=60$

$\text{Minutes}=60\times 45$

1 hour = 60 minutes. To convert minutes into hours, we will divide total minutes by 60.

$\text{Hours}=\frac{60\times 45}{60}=45$

Now, we will divide 1800 by 45 to find average rate in laps per hour as:

$\text{Average rate}=\frac{\text{1800 laps}}{\text{45 hours}}$

$\text{Average rate}=\frac{\text{40 laps}}{\text{ hour}}$

Therefore, Sebastian's average rate is 40 laps per hour.
