Answer: 4 litres of air is held in Braydon’s tank.
Step-by-step explanation:
The law relating pressure to volume is the Boyle's law. It states that the volume of a given mass of gas is inversely proportional to its pressure as long as temperature remains constant. It is expressed as
P1V1 = P2V2
Where
P1 and P2 are the initial and final pressures of the gas.
V1 and V2 are the initial and final volumes of the gas.
From the information given,
V1 = 6 litres
P = 220 psi
P2 = 330 psi
Therefore,
6 × 220 = 330V2
V2 = 1320/330 = 4 litres
You have to multiply 5x times + 2 for all of them
Answer:
x = 15, Angles are both 130!
Step-by-step explanation:
Since this is an example of Alternate Exterior Angles, you could set these equal to eachother!
9x-5 = 7x + 25
-7x -7x
Subtract 7x from both sides.
2x - 5 = 25
+5 +5
Add 5 to both sides.
2x = 30
Divide by two to get x by itself .
x = 15, now you can plug this in for X and get the angle
9(15) - 5 = 130
Answer: D. 5 - x^4
Step-by-step explanation: We can see that the blue function is translated three units up, and inverted, so its leading coefficient is negative. The blue function can be rewritten as -x^4 + 3 to reflect these transformations. The only difference between the blue and the red function is that the red is two units higher, or five units total from the origin. Since they are the same shape, it will have a -x^4 in the formula, but since it is translated five units up its formula will be -x^4 + 5, which is also equal to 5 - x^4.
Because all you do is times that number by itself then when you divide you have to take half of the number then divide it
