Answer:
10/4 <em>per</em> day (2.5 words simplified)
10/3 <em>days </em>he wrote so far (around 3 days simplified)

2.5 x 3 = around 7.5 or 8 words
The K-team can paint a whole house in 60 minutes (super fast!!!). How much of a house can the team paint in 1 minute? The K-team can paint 1/60 of a house per minute.
The C-team can paint a whole hose in 80 minutes. How much of a house can the team paint in 1 minute? The C-team can paint 1/80 of a house per minute.
Suppose both teams paint for the same amount of time -- call the time t (minutes).
Combine the work they do to paint 1 whole house:

Multiply all the terms by the Least Common Denominator, LCD = 240.

Now, can you finish it? By the way, the answer is not a whole number! Hint: it will be between 30 and 40 minutes.

It is a good idea to check to see if your answer is reasonable because a. if your answer is reasonable, you have probably done the problem correctly.
Answer:
Perpendicular(p)=21
base(b)=20
hypotenuse(h)=29
Step-by-step explanation:
Now by using the formula:
cos A=b/h
i.e 20 by 29
