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.

Solve the given inequality. Describe the solution set using the set builder or interval notation. Then graph the solution set on

Sophie [7]

Answer: THIRD OPTION.

Step-by-step explanation:

Given the following inequality:

$3(x-5)\geq 6$

You can follow these steps in order to solve it:

1. Apply Distributive property on the left side:

$3(x-5)\geq 6\\\\(3)(x)+(3)(-5)\geq 6\\\\3x-15\geq 6$

2. Add 15 to both sides of the inequality:

$3x-15+(15)\geq 6+(15)\\\\3x\geq 21$

3. Finally, divide both sides of the inequality by 3:

$\frac{3x}{3}\geq \frac{21}{3}\\\\x\geq 7$

The symbol is $\geq$ means "Greater than or equal to", and indicates that 7 is include in the solution.

Therefore, the solution can be expressed as:

$[7, \infty)$

Now you must mark this point with a closed dot on the number line and shade everything to the right.
