The total amount that Staci had in hand is $200.00.
The ticket at that time costs $87.96.
One Tshirt costs, $30.00.
Now that she has paid ticket, she will deduct the ticket from the cash she has in hand, so as to know the amount she is remaining with.
Tha is, $200-$87.96 = $112.04.
∴ In hand Staci has $112.04 extra cash whereby she can purchase more t shirts.
To get the number of tshirt she can buy, she will divide the amount she has in hand by the amount per piece of t shirt.
For example, $112.04 / $30 = $3.73.
∴ Staci can only purchase threet shirts only at a total cost of $90 for all the t shirts which is $30 × 3 = $90.
Staci has excess of 22.04 after deducting ticket and the other amount she has used to purchase the extra t shirts.
That is, $112.04 - $90 = $22.04.
Answer:
D.Geologists use data from three or more data stations to determine the location of the epicenter.
Earthquakes release seismic waves which can move along a sea.
Considering the Charles' law, the gas would have a temperature of -109.2 C.
<h3>Charles' law</h3>
Finally, Charles' law establishes the relationship between the volume and temperature of a gas sample at constant pressure. This law says that the volume is directly proportional to the temperature of the gas. That is, if the temperature increases, the volume of the gas increases, while if the temperature of the gas decreases, the volume decreases.
Charles' law is expressed mathematically as:
If you want to study two different states, an initial state 1 and a final state 2, the following is true:
<h3>Temperature of the gas in this case</h3>
In this case, you know:
- P1= 1800 psi
- V1= 10 L
- T1= 20 C= 293 K (being 0 C= 273 K)
- P2= 1800 psi
- V2= 6 L
- T2= ?
You can see that the pressure remains constant, so you can apply Charles's law.
Replacing in the Charles's law:
Solving:
<u><em>T2=163.8 K= -109.2 C</em></u>
The gas would have a temperature of -109.2 C.
