The scuba diver must descend 3 feet in the fifth minute to meet the goal.
Why?
To find how many feet does the scuba diver need to descend to reach the goal of 35 feet in 5 minutes, we need to calculate how many feet he did descend on the first 4 minutes.
So, calculating we have:
Hence, we can see that at the 4 minute, he has only descended 32ft. It means that he need to descend 3 feet more in the fifth minute.
Have a nice day!
Using proportions, considering original measures of 10 feet, we have that:
A proportion is a fraction of total amount.
In this problem, the total amount is the original measures of 10 feet.
The horizontal measurement has a scale factor of 75%, hence:
The vertical measurement has a scale factor of 150%, hence:

Answer:
80 square units
536.6
Step-by-step explanation:
First one.
2 Trapezoids
A = x h
A = x 2
A = 16
One rectangle
A = b x h
A = 6 x 8
A = 48
Total Area = 16 + 16 + 48 = 80
Second one:
Two triangles:
A =
A =
A =
A = 43.3
One large rectangle
A = b x h
A = 30 x 15
A = 450
Total Area = 450 + 43.3 + 43.3 = 536.6
