A caterer needs to buy 21 pounds of pasta to cater a wedding. At a store, 8 pounds of pasta cost $12. Hom much will the caterer pay for the pasta here? All I know is how to find the unit rate but I can't figure that out.

$31.50

Step-by-step explanation:

First you need to find out how much a single pound costs($12/8 lbs). That ends up equaling $1.50, so multiply that by 21 and you got the answer. :)

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

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
