A 2-yard piece of ribbon costs $41.28. What is the price per foot?

$61.92

Step-by-step explanation:

a yard is 1/3 of a foot

2 yards = $41.28

which means that 1 yard = $20.64

3 yards = 1 foot

so 1 foot of ribbon =

$20.64 x 3 = $61.92

hope this helps :)

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
