Bentley is working two summer jobs, making $18 per hour lifeguarding and making $8 per hour clearing tables. In a given week, he
Mariulka [41]

Answer:

8 hours

Step-by-step explanation:

First, let's find how much Bentley gets from clearing tables.

5 hours • $8 per hour = $40 total

We can take $40 off his $180 total, leaving the rest for when we figure out how much he needs to work lifeguarding.

$180 needed - $40 earned = $140 left to earn

We know that Bentley makes $18 an hour lifeguarding, so in order to get the number of hours he would need to work in order to make $140, we can divide it by $18.

$140 needed ÷ $18 per hour = 7.77...

We need to convert this to a whole number because we're talking about hours worked, so Bentley would need to work 8 hours lifeguarding to make $140 more. He can only work 15 hours total, so let's check if this exceeds his limit.

5 hours clearing tables + 8 hours lifeguarding = 13 hours < 15 hours max

It is possible to make $180 total from this work schedule, so your answer would be 8 hours.

What is the volume of the figure?
tatyana61 [14]

Answer:

volume of a cone = \pi r^{2} h/3

                          \pi  = 22/7 or 3.14

              r (radius) = 8 ft

             h (height) = 16 ft

∴ volume = 22/7 * 8 * 8 * 16/3

                =  3.14 * 64 * 16/3

                = 1072.76190476 ft^{3}

hope this answer helps you.....
