Answer:

Step-by-step explanation:
Use KCF method for fraction division.
- Keep the first fraction.
- Change the division operation to multiplication.
- Flip the second fraction.


You can use trigonometry and the tangent to get:
tan(11°)=150/x
so x=772 ft
We have the perimeter of first dimension 2(8 + 4) = 24;
The perimeter of the second dimension is 2( 8 + 54 + 4 + 54 ) = 240
We calculate p/100 = 24/240;
Then p/100 = 1/10;
p = 100/10;
p = 10;
Finally, 10% is the answer.
There is a formula for that;
Total time = (Worker 1 * Worker 2) / (Worker 1 + Worker 2)
Total time = (80 * 120) / (80 + 120)
Total time = 9,600 / 200
Total time = 48 minutes
