A truck hauls wheat to a storage granary. It carries a total of 4,970 bushels of wheat in 14 trips. How much does the truck haul

Alex17521 [72]

Answer:

355 bushels.

Step-by-step explanation:

To know the amount of wheat the truck hauls each trip, we need to divide the total amount of bushels of wheat between the total of trips of the truck.

The total amount of bushels is 4970 and the total of trips is 14.

Then, the amount of bushels for each trip would be 4970/14 = 355.

Therefore, the truck hauls 355 bushels of wheat each trip.

Sodium-24 has a half-life of 15 hours. how many grams of a 900 g sample will remain after 90 hours

raketka [301]

Answer: Option 'B' is correct.

Step-by-step explanation:

Let the initial concentration be

$N_0=900\ g$

Let concentration after t= 90 hours be N

Since we have given that Sodium-24 has a half life of 15 hours i.e.

$t_{\frac{1}{2}}=15$

So, According to question,

$\text{ Number of half lives }=\frac{t}{t_{\frac{1}{2}}}\\\\\text{ Number of half lives }=\frac{90}{15}\\\\\text{ Number of half lives }=6$

As we know that

$\frac{N}{N_0}=(\frac{1}{2})^n\\\\N=N_0\times (\frac{1}{2})^n\\\\N=900\times (\frac{1}{2})^6\\\\N=\frac{900}{64}\\\\N=14.0625\ g$

Hence, Option 'B' is correct.
