There are 25 students in Laura's class, and 21 of the students went on the class trip to the zoo. What percentage of students went on the class trip? (Explain for brainlist)

84%

Step-by-step explanation:

A percentage is really a fraction with the denominator of 100. That means we can take the fraction of the students that went to the field trip (21/25) and make the denominator to 100. Since 25x4 is 100 we can do that but we also must do 21x4 because what you do to the top of the fraction you must do to the bottom. So you'd get 84/100 which is 84%

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
