Answer:
Step-by-step explanation:
Given
Number of service bays
Time taken by each bay to finish one oil change
Working capacity hours per day
Thus, in hours the total number of times one bay has changed the oil is equal to
If one service bay's capacity is equal to , capacity of two service bays is equal to
Thus, the design capacity is
$6.40
All beads and pendants = $19.20, and the beads equal $12.80, so 12.80 + ? = 19.20. So you would use the equation. 19.20 - 12.80, which equals 6.40.
The area is 50.24 cm.
The formula is π·r^2.
The radius is 4 cm, and you square it. 16 cm.
Then you multiply 16 by 3.14 (π). And you get 50.24 cm as the area.
