Answer:
MISSING LENGTH IS 12 M
Step-by-step explanation:
9+9+ ? + ? = 42m
18+ X + X = 42m
2X=42-18
2X=24
X=12
The key concept you must have to remember is that, the rate is kept constant, as what is specified in the problem. Our basis for the rate is the first situation.
Rate = 20 facts/ 1 min.
Let's equate this to the second situation using x as the time unknown.
20/1 = 35/x
Solving for x,
<em>x = 1.75 minutes</em>
X=40 the right angle is 90 degrees and 90-10 = 80, 80 = 2x, so x = 40
3.375 because 9 is 3/4th of the 12 so you would divide 4.5 by 4 and multiply by 3 and it gives you 3.375
