Answer: 1, 10
Step by step explanation:
Answer: 26.5cm2
Step-by-step explanation:
A) time = distance/speed
For the first half of the trip, the time used was
.. (1 mi)/(12 mi/h) = (1/12) h = 5 minutes
Then the last half of the trip took 10 minutes, 1/6 hour.
.. speed = distance/time
.. = (1 mi)/(1/6 h) = 6 mi/h
The speed for the last half of the trip was 6 mph.
b) The average speed was
.. (2 mi)/(1/4 h) = 8 mi/h
Ling's average speed was 8 mph.
Answer:
c) IS THE ANSWER
Step-by-step explanation:
Answer:
The maximum value of the feasible regions is P=500
Step-by-step explanation:
we know that
To find out the maximum value of the feasible regions, substitute the value of x and the value of y of each region in the objective function P and then compare the results
we have

Region 1 (0,5)
For x=0, y=5
substitute

Region 2 (0,4)
For x=0, y=4
substitute

Region 3 (4,0)
For x=4, y=0
substitute

Region 4 (3,0)
For x=3, y=0
substitute

Compare
The maximum value of the feasible regions is P=500
