<h2>Answer:</h2><h2>When the volume is 60 cubic centimeters, the pressure is 4.26 pounds</h2>

Step-by-step explanation:

Let V be the volume of the gas and P be its pressure.  

The volume of a gas in a container varies inversely with the pressure on the gas:  

    V = k/P

VP = k, where k represents constant temperature

Given the volume is 32 cubic centimeters at a pressure of 8 pounds

where V1 = 32, P1 = 8 ... (1)

The pressure when the volume is 60 cubic centimeters,

V2 = 60, P2 = ?  ... (2)

Comparing eq (1) and (2)

V1 P1 = V2 P2

32 (8) = 60 (P2)

256 = 60 (P2)

P2 = \frac{256}{60}

P2 = 4.26 pounds

Gia got some books from Library yesterday she got five books today Gia returned three books Gia has six books how many books did
makvit [3.9K]

Answer: 4


Explanation:


You can write an algebraic expression to represent the sequence with the books in this way:

  • yesterday she got five books: 5
  • today returned three books: - 3
  • how many books did Gia have to begin: n
  • At the end she has six books, which means that you can set an equality:

       n + 5 - 3 = 6

Now you follow these steps to clear the unknown:

  • do the operations in the left side: n + 2 = 6
  • use subtraction property of equality: n = 6 - 2
  • do the operations: n = 4

And that is the number of books whith which Gina started: 4

Find the value of x.
Shalnov [3]

Answer:

74 degrees

Step-by-step explanation:

The arc degree measurement of the arc that is colored in orange is given as 254 degrees.

The remaining part is the part in green.

The green part plus the orange part should equal 360 degrees because that would make a full rotation around the circle.

360-254=106.

The green arc has measurement 106 degrees.

We can find x by computing half the difference of the arcs there.

That is,

x=\frac{1}{2}(254-106)

x=\frac{1}{2}(148)

x=74
