The area of the garden is 74 square feet
<h3>How to determine the area of the garden?</h3>The complete question is added as an attachment
From the attached figure, we have the following shapes and dimensions:
- Rectangle: 10 by 5 feet
- Trapezoid: Bases = 10 and 6; Height = 3
The rectangular area is
A1 = 10 * 5
Evaluate
A1 = 50
The area of the trapezoid is
A2 = 0.5 * Sum of parallel bases * height
This gives
A2 = 0.5 * (10 + 6) * 3
Evaluate
A2 = 24
The total area is
Total = A1 + A2
This gives
Total = 50 + 24
Evaluate
Total = 74
Hence, the area of the garden is 74 square feet

The expected waiting time in system for typical truck is 2 hours.
Step-by-step explanation:
Data Given are as follows.
Truck arrival rate is given by, α = 36 / day
Truck operation departure rate is given, β= 48 / day
A constructed queuing model is such that so that queue lengths and waiting time can be predicted.
In queuing theory, we have to achieve economic balance between number of customers arriving into system and that of leaving the system whether referring to people or things, in correlating such variables as how customers arrive, how service meets their requirements, average service time and extent of variations, and idle time.
This problem is solved by using concept of Single Channel Arrival with exponential service infinite populate model.
Waiting time in system is given by,
where is waiting time in system
is arrival rate described Poission distribution
is service rate described by Exponential distribution
...it is due to 1 day = 24 hours
Therefore, time required for waiting in system is 2 hours.
Answer:
Rational, Rational, Rational, Irrational, Irrational
Step-by-step explanation:
The first question:
- -√49
- -7
This number is rational
Second:
- -70.8888....
This number is rational. It wouldn't be rational if the digits won't repeat.
Third:
- 15.91
This number is rational
Fourth:
- 17π
This is irrational. The digits of pi do not repeat, making it irrational.
Fifth:
- -√14
Irrational. The square root of a non-perfect square is irrational.
