Use the ideal gas law:

PV=nRT

(1.62\,\mathrm{atm})V=(2.50\,\mathrm{mol})\left(8.314\dfrac{\rm J}{\mathrm{mol}\cdot\mathrm K}\right)(295.2\,\mathrm K^\circ)

\implies V=37.34\,\mathrm L

Marigold Corp. took a physical inventory on December 31 and determined that goods costing $209,500 were on hand. Not included in
yaroslaw [1]

Answer:

Marigold should report an inventory amount of $265,000.

Explanation:

The term FOB (Free On Board) describes at what point the ownership of goods is transferred from the seller to the buyer. In case of FOB shipping point, the ownership of the goods is transferred to the buyer once the goods are shipped for transit. In case of FOB destination, the ownership of the goods is transferred to the buyer once the goods are received by the buyer.

Therefore, the goods in transit <em>purchased </em>by Marigold on FOB shipping point basis should be added to its inventory. The goods in transit <em>sold </em>by Marigold on FOB destination are also currently owned by Marigold so they shall also be added to its inventory.

The inventory amount to be reported by Marigold is computed as follows.

Physical inventory in hand                                          $209,500

Add: Purchases on FOB shipping point basis           $28,000

Add: Cost of goods sold on FOB destination basis  $27,500

Inventory amount to be reported                              $265,000

How long will each person take to run a total of 50 miles at the given rates?
forsale [732]
Problema Solution

Terrance and Jesse are training for a long-distance race. Terrance trains at a rate of 6 miles every half hour, and Jesse trains at a rate of 2 miles every 15 minutes.

How long will each person take to run a total of 50 miles at the given rates?

Answer provided by our tutors

d = 50 mi the distance
t1 = the time of Terrance
t2 = the time of Jesse
Terrance trains at a rate of 6 miles every half hour thus his rate is:
v1 = 6/0.5 = 12 mph
Jesse trains at a rate of 2 miles every 15 minutes thus his rate is:
v2 = 2/(15/60) = 8 mph
since speed = distance/time follows time = distance/speed:
t1 = d/v1
t1 = 50/12
t1 = 4 1/6 hr
t1 = 4 hr 10 min
t2 = d/v2
t2 = 50/8
t2 = 6 1/4 hr
t2 = 6 hr 15 min
Terrance will run 4 hours and 10 minutes.
Jesse will run 6 hours and 15 minutes.
