The right options are;
1. to reduce the amount of water dumped into the city’s sewer system
2. to replace water lost to evaporation in the office air-conditioning system
4. to irrigate the plants and trees throughout the building
5. building to humidify and chill the tower’s ten-story atrium.
The roof of the Hearst Tower has been designed to collect rainwater in order to reduce the amount of water dumped into the city’s sewer system during rainfall by 25percent. The rainwater obtained is conserved and used efficiently. The rain water is used to replace water lost to evaporation in the office air-conditioning system, to irrigate plants and trees within and outside of the building and it also serve to humidify and chill the tower's ten story atrium as required.

Answer:
15.625 g of a 500 gram sample of potassium-42 with 12.4 hours of Half -life is left after 62 hours.
The half-life is the time after which half of the initial quantity of a radioactive substance is left .
Given here,
The half-life of K-42 = 12.4 hours
The initial quantity of K-42 = 500 gm
The final quantity after 62 hours = ?
The number of half cycle
\bold { = 62\times \dfrac 1{12.4} = 5,}=62×
12.4
1
=5,
Thus the number of half life cycles in 62 hours is 5,
After 1 half life \bold {= \dfrac {500}{2} = 250}=
2
500
=250
After 2 half lives \bold {= \dfrac {250}{2} = 125}=
2
250
=125
After 3 half lives \bold {= \dfrac {125}{2} = 62.5}=
2
125
=62.5
After 4 half lives \begin{gathered}\bold {= \dfrac {62.5}{2} = 31.25}\\\end{gathered}
=
2
62.5
=31.25
After 5 half lives \begin{gathered}\bold {= \dfrac {31.25}{2} = 12.625}\\\end{gathered}
=
2
31.25
=12.625
15.625 g of a 500 gram sample of potassium-42 with 12.4 hours of Half -life is left after 62 hours.
