August hosted two dinner parties for his friends. twenty-five guests attended the first party, and thirty-three guests attended the
second party. what is the percentage increase of the number of guests from the first party to the second party?

32%

Step-by-step explanation:

To find percentage increase, we use the formula change/original x 100. In this case, the change is 8 while the original is 25. 8/25 x 100 = 32

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)
