Answer: 
12.5
Step-by-step explanation: The triangle ABC and its altitude 
is represented in the figure below.
<u>Altitude</u> is a segment of line that link a vertex and the opposite side, forming a right angle.
So, because of , now we have two similar triangles, which means that ratios of corresponding sides are equal:
(1)
This is always true for a right triangle and a altitude drawn to the hypotenuse.
Triangle BDC is also right triangle. So, we can use Pythagorean theorem to determine the missing side.
(2)
Substituting (2) into (1):
We want to find f, so:
f = 7.5
The length of 
is
The length of the hypotenuse of triangle ABC is 12.5 units.

Answer:
24 picture frames
Step-by-step explanation:
Since a student takes 1/6 hour to paint a picture frame, so in an hour, the student will paint a total of 6 picture frames. So to find the number of picture frames in 4 hours, you just need to multiply 4*6 to get 24 picture frames.
There are three friends and 4 cups. Each friend can have a whole cup each and need to split the last cup 3 ways (1/3)
Each friend would get 1 cup and 1/3 of a cup
(I hope I’m right~)
Answer:
790 units^2
Step-by-step explanation:
Take the area of each side and add them all up. Remember each side is there twice.
Formula: SA = 2(15*5 + 15*16 + 5*16)
SA = 2(75 + 240 + 80)
SA = 2(395)
SA = 790
