Answer:
(8 / x) + (21 / y)
Step-by-step explanation:
Given that:
Average driving speed = x mph
Miles driven to work = 8 mile
Miles by train to work = 21 miles
Average train speed = y
Total time taken to get to work. :
Recall : time taken = distance / speed
Hence,
Time taken =) total distance / average driving speed)
Total time taken = (8 / x) + (21 / y) hours
Total time taken = (8 / x) + (21 / y) hours

Step-by-step explanation:
Answer:
156.5375 cm
Step-by-step explanation:
The function used to estimate the height is F(x)
F(x) = 2.75x + 71.48
The humerus is xcm long. When x = 30.93cm, we put x = 30.93 into the function F(x)
F(30.93) = 2.75(30.93) + 71.48
= 85.0575 + 71.48
= 156.5375 cm(4 decimal places)
