The ideal gas law relates the pressure P , volume V , and temperature T of a fixed number of molecules of a gas in a container v

ia: PV= nRT where R =.082 is constant, using pressure units atm , volume units L , and temperature units K . Suppose there are a fixed amount n =12 moles of oxygen in a container. Determine the rate at which the pressure is changing when the pressure is 4.1 atm and the temperature is 22.5K , if the volume is being decreased by 0.3 L/s and the temperature is being increased by 0.06 K/s.

Francis went to the sporting goods store and spent $75.15 on 6 items.
MArishka [77]

Answer:

$6.03

Step-by-step explanation:

The question is asking us how much each pair of socks cost. With the information we are given, we know that there are 5 pairs and that they all cost the same amount. If the total were just the 5 socks, we could easily divide the total by 5 to get the price of each pair but that's not the case. The soccer ball is included in the final cost. To overcome this, we just have to subtract the soccer ball's cost ($45) from the total.

So we subtract $45 from $75.15, giving us $30.15, the total amount of all the socks. However we need to find out how much each pair costs and there are 5 of them, so we divide 30.15 by 5. This gives us the answer, $6.03.

Each pair of socks cost $6.03.

Simpler Explanation:

  • $75.15 - $45 = $30.15
  • $30.15 / 5 = $6.03

The answer is $6.03

1) 2m + 3m2 - 4m
Lilit [14]

Answer:

1) 2m + 3m2 - 4m=7

7) 3m2 – 2m + 4m= 11

8) 20 + 109 + 39 - 4= 164

3) 2m + 4m - 3m2= -3

9) 4xy + x + 2xy= 0

4) 2y + 14x - 7x + 9y= 18

10) 6m2 - 6m - 9m2= -51

What’s the answer to this problem???
Snowcat [4.5K]
Rewrite the equation into slope intercept form:
8y = -5x+16

divide everything by 8 to get just y
y = -5/8x+2

 the slope = -5/8

Connor rolled a die 6 times. A 2 occurred three times. Why isn't the theoretical probability 3/6 instead of 1/6?​
Cerrena [4.2K]

2 occurred 3times

\\ \sf\longmapsto S=6\times 3=18

\\ \sf\longmapsto |S|=18

Now

\\ \sf\longmapsto E=No\:of\:times\: 2\:occured

\\ \sf\longmapsto |E|=3

we know

\boxed{\sf P(E)=\dfrac{|E|}{|S|}}

\\ \sf\longmapsto P(E)=\dfrac{3}{18}

\\ \sf\longmapsto P(E)=\dfrac{1}{6}
