Lisa [10]

area of OAB = 72 = (1/2) sin (AOB) * OA * OB solve the above for sin(AOB) to find sin(AOB) = 1/2 area of ODC = 288 = (1/2) sin (DOC) * OD * OD Note that sin(DOC) = sin(AOB) = 1/2, OD = 18 + y and OC = 16 + x and substitute in the above to obtain the first equation in x and y 1152 = (18 + y)(16 + x)...

An auto service center that specializes in oil changes has two service bays that serve, on average, a total of 24 cars per eight
inysia [295]

Answer:

32

Step-by-step explanation:

Given

Number of service bays = 2

Time taken by each bay to finish one oil change = 30 minutes

Working capacity = 8 hours per day

Thus, in 8 hours the total number of times one bay has changed the oil is equal to

\frac{8 * 2 * 30}{30} \\= 16

If one service bay's capacity is equal to 16, capacity of two service bays is equal to

16 * 2 \\= 32

Thus, the design capacity is 32
