As the pen is a triangle, the third side can either be the hypotenuse or a regular side. If the third side is the hypotenuse, it's length would be
feet. If the third side is a regular side, than it would be
≈12.689 feet. This means your third side can either be 17 feet long or 12.689 feet long.
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!
Answer:
$25
Step-by-step explanation:
Multiply $20 by 0.25 (which is 25% as a decimal)
$20 x 0.25 = $5

Answer and workings in the attachment below.
To find the mean (average), we first need to add up all the test scores (14 + 19 + 19 + 20 + 16 + 18 + 15 + 17 + 12 = 150). Then, we need to divide that number (150) by the number of numbers in the data set (9 in this case). So the mean of these test scores is about 16.6666666667.
