This problem is an inverse proportion case. Having two variables: number of workers and time (in days); when we increase the number of workers, the time needed decreases; vice versa. Therefore, we can use the multiplication method: (workers * time) will always stay constant.
Let's say the time (in days) needed by the eleven workers is t,
5*20 = (3*10) + (14*t)
100 = 30+14t
70 = 14t
5 = t
It will take the eleven-workers 5 more days to finish the road.
franklin's population is growing by 1000 people per year(5% of 20000 is 1000) and Chester is growing by 500 per year so at year 13 franklin will be at 32000 while Chester is at 31500
To find the length of the ladder, you need to do Pythagorean theorem. 50^2 + 30^2 = x^2 2500 + 900 = x^2 x^2 =3400 x= square root of 3400 58.31 OR 10 root34
To find the angle: tan theta = opposite/adjacent 50/30 = 5/3 theta = tan inverse of 5/3 = 59.04
