Answer:
it took the remaining two builders five days to finish
Answer:
3√58/58.
Step-by-step explanation:
The sine is the opposite side / hypotenuse so we need to find its length.
By Pythagoras h^2 = 3^2 + 7^2
= 58.
So the hypotenuse h = √58.
So sine theta = 3 / √58.
Now multiply the top and the bottom of this fraction by √58, we get:
3√58/58.
1. The fastest way to produce the tables is to have the person in-charge of finishing and packaging help with the preparation. Then, the person in-charge of preparation and packaging can help with the assembly. The finishing can also be done by three people. Finally, the packaging step can be helped by assembly and finishing people. This would produce more tables per day.
2. No. It would be better if the backup person can help with the task.
3. Tom could do the packaging since he'd be free after doing his step.
4. The scheme in No. 1 can be used.
