A=p+prt solve for r
Answer:
Step-by-step explanation:
The first step is to take p on both sides:
On the right hand side, cancel p and -p, since . The equation will be:
Then, divide both sides of the equation by p*t:
On the right hand side, p*t can be cancelled:
Answer:
r=A-p (the line is the bar so this is a-p over pt)
pt
Step-by-step explanation:
P+Prt=A
Prt=A−P isolate the term which contains r
Prt=A−P
divide pt by each side
Well, decreasing is the same as a negative slope which will always start at the bottom right and go towards the top right.
With this being said, A and C both fit this description, so your answers are A and C.
Hope this helps!
Answer:
The new volume is 1.63 L
Step-by-step explanation:
A tire pump has a volume of 1.5 L, while the temperature is 5 °C When the temperature changes to 30 °C, the volume will change as well.
The pressure remains constant.
Since the pressure is constant we can use the following formula:
V1/T1 = V2/T2
V1 = the initial volume = 1.5L
T1 = the initial temperature = 5 °C = 273.15 + 5 = 278.15 K
V2 = the final volume = TO BE DETERMINED
T2 = the final temperature = 30 °C = 273.15 + 30 = 303.15 K
1.5L/ 278.15 Kelvin = V2/303.15 K
V2 = (1.50L * 303.15 Kelvin) / 278.15 Kelvin = 1.63 L
When the temperature increased from 5°C to 30°C, the volume will change to 1.63 L
