On the first day of camp, 5/6 of the skaters were beginners. of the beginners, 1/3 were girls. what fraction of the skaters were girls and beginners?

Our required fraction is

Step-by-step explanation:

Since we have given that

Part of the skaters were beginners is given by

Of the beginners, part of it were girls is given by

So, Fraction of the skaters were girls and beginners is given by

Hence, our required fraction is

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

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
