Answer:
$ 67.15 tax
Step-by-step explanation:
the tax would be 7.9% of 850
turn ur percent to a decimal....and " of " means multiply
0.079 * 850 = 67.15 <==
By adding 3 to both sides and dividing both sides of the equation by 4 you end up with x=6
answer is x =6
Hope this helps!!
The answer is 4.5 l
To calculate this, we will use the Boyle's law using constant k, pressure P, and volume V:
PV = k
We can forget temperature since it is constant.
We have:
P1V1 = k
P2V2 = k
So, P1V1 = P2V2
P1 = 3 atm
V1 = 1.5 l
P2 = 1 atm
V2 = ?
_____
P1V1 = P2V2
3 atm * 1.5 l = 1 atm * V2
4.5 atm/l = 1 atm * V2
V2 = 4.5 atm l / 1 atm
V2 = 4.5 l
