Assuming you means 6.5% tax of a $42 purchase
0.065*42=2.73
tax is $2.73
The value of the pressure is 1 when the value of volume is 10 liters, the correct option is D.
<h3>What is the pressure?</h3>
Pressure is defined as the physical force exerted on an object.
The force applied is perpendicular to the surface of objects per unit area.
Given
The equation is

Where the v is the volume and p is the pressure.
The value of p when the value of volume v is 10 liters is;

Hence, the value of the pressure is 1.

Answer:
no value of X so no answer
Step-by-step explanation:
Length= 2*width
area=l*w=2*width*width=2*width^2
area+160=(2*width+1)*(width+1)
A+160=2w^2+2w+w+1
A+160=2w^2+3w+1
putting value of a
2w^2+160=2w^2+3w+1
160=3w+1
w=53m
l=106m
