Say if the earth rotates 1.25 degrees in 5 mintues. but a classmate wants to find out how many degrees the earth can rotate in 2 minutes. she does a problem:   she  puts 1.25 over 5  and divides them both  by 2, and her answer was 0.625 over 2.5.    explain her error and give the correct rate.( ! )

Her error was dividing them by 2 she would place 1.25 over 5 then divide by 5 to get the unit rate per minute then multiply the quotient by 2 to get the rate of degrees moved for 2 minutes which is .5  or .50 degrees every two minutes.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

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
