Answer:
Part 1) 
Part 2) 
Part 3) 
Part 4) 
Part 5) 
Part 6) 
Step-by-step explanation:
Part 1) we know that
The shaded region is equal to the area of the complete rectangle minus the area of the interior rectangle
The area of rectangle is equal to

where
b is the base of rectangle
h is the height of rectangle
so



Part 2) we know that
The shaded region is equal to the area of the complete rectangle minus the area of the interior square
The area of square is equal to

where
b is the length side of the square
so



Part 3) we know that
The area of the shaded region is equal to the area of four rectangles plus the area of one square
so



Part 4) we know that
The shaded region is equal to the area of the complete square minus the area of the interior square
so



Part 5) we know that
The area of the shaded region is equal to the area of triangle minus the area of rectangle
The area of triangle is equal to

where
b is the base of triangle
h is the height of triangle
so



Part 6) we know that
The area of the shaded region is equal to the area of the circle minus the area of rectangle
The area of the circle is equal to

where
r is the radius of the circle
so


The correct answer is 50:1 I got that one right!
The pie must stay for 60 - x more minutes must the pie bake
<h3>For how many more minutes must the pie bake?</h3>
Let the amount of time spent in the oven be x
So, we have
Total amount of time = 60 minutes
This means that
Remaining time + Amount of time spent = 60
This gives
Remaining time + x = 60
Evaluate
Remaining time = 60 - x
Hence, the pie must stay for 60 - x more minutes must the pie bake
