The measurement of a pressure valve starts at 36 psi and falls to 30 psi. What is the approximate percent decrease in the reading on the pressure valve.
a.17%
b.20%
c.80%
d.83%

the answer is a 17psi

Step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
