Answer:
1 hour and 42.85 minutes.
Step-by-step explanation:
It is found from the process of reviewing that experience survey a roadbed in 3 hours.
Hence, in 1 hour the experience survey 
of the roadbed.
Again, it is found that the apprentice survey needs 4 hours to survey the same stretch of road.
So, in 1 hour the apprentice survey does 
of the roadbed survey.
If they work together then in 1 hour, the survey work will be done by (
)= 
parts.
Therefore, the total survey they will complete working together in 
hours i.e. 1 hour and 42.85 minutes. (Answer)

Step-by-step explanation:
The perimeter of the figure to the nearest tenth is 44.6 units
<h3>Perimeter of a figure?</h3>
The perimeter of a figure is the sum of the whole sides.
Therefore,
A parallelogram has opposite sides equal to each other.
Therefore, the perimeter of the figure is as follows;
The figure combines a parallelogram and a semi circle.
Therefore,
perimeter of the figure = 4 + 14 + 14 + πr
perimeter of the figure = 32 + 3.14 × 4
perimeter of the figure = 32 + 12.56
perimeter of the figure = 44.56
perimeter of the figure ≈ 44.6 units

Well, the form
gives the maximum (if a<0) at coordinates
, where
. If a>0, the same formula gives the minimum (there's no maximum)
