<span>Josh swims 5 more hours per week than David so his hours = 3x + 5
His </span><span>average speed is 4 laps per hour less than David's so it is = x - 4
</span>
Total distance = hours * speed
= (3x + 5)*(x - 4)
= 3x^2 - 7x - 20

E is midpoint of A and C, B and D
Answer:
513.95
Step-by-step explanation:
First you have to divide 7776 by 343. Then you raise the answer to the second power
Y=-1/4x
you can tell because the line is going down if you read it from left to right, so it is a negative slope, and if you looks at 2 points where the line crosses, it goes down one, and to the right four
rise over run
Answer: Total hours for the week: 42
Overtime Hours: 3 (anything over 8 hours per day in most places)
Step-by-step explanation:
For each shift, subtract the starting time from the ending time.
Then add the morning hours to the afternoon hours to get the daily total. Overtime is anything more than 8 hours.
Add all the daily totals to get the weekly total.
Add the overtime hours from any days with over 8 hours.
For example:
Tuesday: morning 11:00 - 7:00 = 4 hours. afternoon 17:00 - 12:00 = 5 hours
4 + 5 = 9 hours daily total. 9 - 8 = 1 hour overtime
<em>You can convert hours to minutes to figure times like 10:30 - 9:00</em>
<em>1 hour - 60 minutes, So from 9 to 10am is one hour 60-30 = 30. 30/60 =1/2</em>
<em>Then you can convert the fraction to a decimal 1/2 = .5 </em>
<em>So 10:30 - 9:00 is 1:30 changed to a decimal is 1.5 hours. </em>
