the pressure, p. of a gas varies inversely with its volume, v. Pressure is measured in units of Pa. Suppose that a particular am
LekaFEV [45]

I think I know how to do it


Your equation is:

P₁V₁ = P₂V₂


You Know:

Initial:

P₁ = 84 Pa

V₁ = 336 L


New:

P₂ = ?

V₂ = 216L


Plug this into the equation:

P₁V₁ = P₂V₂

(84 Pa)(336 L) = P₂(216 L)     Divide 216 on both sides

\frac{(84Pa)(336L)}{216L}=\frac{(P_{2})(216L)}{216L}

130.6666666 = P₂    

(if your doing significant figures, you have 2 sig figs)

130 Pa = P₂

I need help with these math questions
ss7ja [257]
A) m=months passed
f(m)=2*1.05^m

b) 8 weeks=2 months
f(2)=2*1.05^2=2.205
so essentially still 2

c)100=2*1.05^m
50=1.05^m
log1.05(50)=m
log(50)/log(1.05)=m=80.18

so after 80 months she will have nearly 100 cats (99.12), but will only break through the 100 with her 81st month

3.9 times 10 to the seventh power
ra1l [238]

Hey there!

3.9 times 10 to the seventh power is equivalent to the equation 3.9 × 10^{7}

The seventh power indicates the amount of times the decimal moves to the right of 3.9, so that expression would be equivalent to 39,000,000.

Hope this helps!
