Answer: A minimum of 5 people will be needed.
Step-by-step explanation:
150/32 = 4.6875
You can't have a partial person, so round up to 5.
It may be possible to have 4 employees working 32 hours and another working 22 hours, but that is not what the question asks exactly. That is still 5 people.
Using compound interest, it is found that he must deposit $56,389.
Compound interest:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
- t is the time in years for which the money is invested or borrowed.
In this problem:
- Hopes to have $80,000 in 20 years, thus
. - Interest rate of 1.75%, thus
. - Compounding monthly, thus
![n = 12](https://tex.z-dn.net/?f=n%20%3D%2012)
- The investment is of P, for which we have to solve.
Then:
![A(t) = P(1 + \frac{r}{n})^{nt}](https://tex.z-dn.net/?f=A%28t%29%20%3D%20P%281%20%2B%20%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D)
![80000 = P(1 + \frac{0.0175}{12})^{12(20)}](https://tex.z-dn.net/?f=80000%20%3D%20P%281%20%2B%20%5Cfrac%7B0.0175%7D%7B12%7D%29%5E%7B12%2820%29%7D)
![P = \frac{80000}{(1 + \frac{0.0175}{12})^{12(20)}}](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7B80000%7D%7B%281%20%2B%20%5Cfrac%7B0.0175%7D%7B12%7D%29%5E%7B12%2820%29%7D%7D)
![P = 56389](https://tex.z-dn.net/?f=P%20%3D%2056389)
He must deposit $56,389.

Answer:
$3.70 honestly just divide lol
It is B. Point 8, 4 is on the graph. B is the only one that give 8, 4 as an option.
IF the estimates are 100% accurate, then the maximum volume of concrete is the product of the maximum dimensions, namely
Vmax=18.32*12.22*0.55=123.13 m^3
and the minimum volume of concrete is the product of the minimum dimensions
Vmin=18.28*12.18*0.45=100.19 m^3
the uncertainty is therefore 123.13-100.19=22.94 m^3
On the practical side, to this uncertainty must be added to
- squareness of the formwork
- evenness of the surface of the crushed stones on which the foundation sits on
- excess of concrete delivered by the truck
- volume of air bubbles trapped in the the concrete, ...
