The second term in a geometric sequence is 20. the fourth term in the same sequence is 45/4, or 11.25. what is the common ratio in the sequence?

11.25 = 20 x r^(3-1)

11.25 = 20 x r^2

11.25/ r^2

0.5625 = r^2

square root 0.5625 = r

0.75 = r

r= 0.75 or 3/4

Step-by-step explanation:

the answer is a

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
