Answer and Explanation:
a) the advantage if using Nitrogen is that pure nitrogen does not leak out of tires as fast as oxygen do. Molecules of Nitrogen are much larger that those of Oxygen so nitrogen filled tires will remain inflates longer than air filled tires.
b) it is consistent with the ideal gas law (PV= nRT). Volume is inversely proportional to pressure and directly proportional to the temperature which mean that every 10 degree change in temperature will result in 1 psi change in tire-inflation pressure.
c) Yes there is another chemical reason. Air contains moisture which can build up within and corrode the wheels and tire pressure monitoring system resulting in tire rot from within but Nitrogen gas is much drier and allows a more steady pressure inside the tire.
d) No I will not pay extra for nitrogen filled tires because there's no huge difference between nitrogen and air filled tires. Nitrogen contains only about 93-95% nitrogen and the rest air ,while ordinary air-filled tire contains 78% nitrogen and the rest air. Besides nitrogen gas do not protect nor repairs faulty tires, you still have to check your tires from time to time and ordinary air is much cheaper than nitrogen and in some regions free. So I think its just a marketing strategy and do not have much use.
Answer:
B) 58.3%.
C) 87.5% y 12.5%.
D) $320.
Explanation:
B) Dado que José Luis trabajó 7 meses del año, para determinar qué porcentaje del año trabajó se debe realizar el siguiente cálculo:
12 = 100
7 = X
7 x 100 / 12 = X
700 / 12 = X
58.3 = X
Por lo tanto, José Luis trabajó 58.3% del año.
C) Dado que Lucero presentó un examen en el que 35 preguntas fueron correctas y 5 incorrectas, para qué porcentaje de las preguntas contesto correctamente y qué porcentaje fue incorrecto se debe realizar el siguiente cálculo:
40 = 100
35 = X
35 x 100 / 40 = X
3500 / 40 = X
87.50 = X
Por lo tanto, Lucero contesto un 87.5% de preguntas correctamente, y un 12.5% incorrectamente.
D) Dado que el costo de una camisa es $400 y tiene un descuento del 20%, para determinar cuál es el precio de la camisa con el descuento se debe realizar el siguiente cálculo:
1 - 0.2 = 0.8
400 x 0.8 = 320
Por lo tanto, el costo de la camisa fue $320.

Answer:
The answer is D) will raise disposable income and raise spending
Explanation:
When taxes are cut disposable income increases as there is less income used to pay taxes. If there is a higher amount of disposable income available then spending will increase as well as spending appetite.
Cutting taxes is a easy way to stimulate spending in an economy.
The correct answer is therefore D) will raise disposable income and raise spending.
Cutting taxes can also increase aggregate demand which can lead to higher economic growth as well.
