Answer:

Bonnie needs 67.8\ in of ribbon

Step-by-step explanation:

A Kite is a quadrilateral that has two pairs of equal sides

To find out how much ribbon Bonnie needs calculate the perimeter of the kite

P=2(L1+L2)

where

L1 is the length of one side

L2 is the length of the other side

P=2(13.2+20.7)=67.8\ in

Barry is 8 years older than his sister. In 3 years, he will be twice as old as she will be then. How old is each now?
Colt1911 [192]

Answer:

Step-by-step explanation:

Present age of Barry = b

Present age of sister = s

Barry is 8 years older than his sister means if we subtract 8 from present age of Barry both will be of equal age

s=b-8 ............(1)

In 3 years means we have to add 3 in their present age

s+3=b+3

then

he will be twice as old as

2(s+3)=(b+3

2s+6=b+3

2s=b+3-6

2s=b-3...............(2)

Put the value of s from (1) to (2), we have

2(b-8)=b-3

2b-16=b-3

2b-b=-3+16

b=13

Put the value of b in (1)

s=13-8

s=5

Present age of Barry = b = 13

Present age of sister = s = 5
