<span>The pressure, P, of a gas, varies inversely with its volume, V
</span>
∴ PV = k where k is constant
<span>The pressure is 84 Pa at a volume of 36 L.
</span>
<span>∴ at P = 84 ⇒⇒⇒ V = 36
</span>
<span>∴ K = PV = 84 * 36 = 3,024 ⇒⇒(1)</span>
If the volume is expanded to 216 L, what will the new pressure be?
We need to find P at V = 216
From the equation (1) ⇒⇒⇒ PV = 3024
substitute with V = 216
∴ 216 P = 3024
∴ P = 3024/216 = 14
The correct answer is option <span>B. 14 Pa</span>
Answer:
0.42 ÷ 7
Step-by-step explanation:
There is a total of 42 squares out of 100 in the diagram.
It is broken into 7 equal parts.
This can be represented by 0.42 ÷ 7
Chocolate, Vanilla, and Strawberry with sprinkles marshmallows, and peanuts.
Answer:
X=560
Step-by-step explanation:
600-40=560 im not sure
Less than means minus so 7 less than means -7
-2 times a number x means -2 times x or -2x
is greater than or equal to means <u>></u>
41=41
so
-7+-2x<u>></u>41
-2x-7<u>></u>41
add 7 to both sides
-2x<u>></u>48
divide both sides by -2
remember to flip sign since divided by negative
x<u><</u>-96
