Answer:
it takes longer for the boat to get back because it's moving against the current. to see how fast the boat is moving, you divide the amount of miles traveled, by how long it took.
240/20 = 12
in still water the boat travels it's 12 miles per hour
240/ 60 = 4
against the current, the boat travels 4 miles per hour
if you need to find the speed of the current, you need to find the resistance that's going against the boat making it slow down. you do that by doing 12 - 4 = 8 miles per hour is the speed of the current.

Answer: 5.18 pounds
Step-by-step explanation:
Given: The pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the gas.
Let 'p' denote the pressure exerted on the walls and 't' denotes temperature of the gas.
Then the equation is given by :-
, where c is the proportionality constant.
Also, the pressure is 6 pounds per square inch when the temperature is 440° F.

Then, the final equation to calculate pressure becomes :-

Now, the pressure exerted when the temperature of the gas is 380°F is given by :-

Answer:
The width of the carpet is 12 inches and the length of the carpet is 120 inches.
Step-by-step explanation:

^We can distribute first^
Distributing would result in:

Then we would combine like terms, which would result in:

Then we solve the equation.

Since the width of the carpet is 12 (as we figured out). The statement said that "The length of the carpet is 108 inches more than the width."
So now we add 108 to 12 to figure out the length.

The length of the carpet is 120 inches.
21a + 9 = 0 that is the answer good luck
