Joan has 2 silimar rectangular-shaped pieces that she is using for her quilt. one has width 4 inches and length 6 inches and the other has a width of 6 inches. what is the perimeter of the larger rectangular piece?

The answer to your question is: 30 in

Step-by-step explanation:

Data

1 piece

Width = 4 in

Length = 6 in

2 piece

Width = 6 inches

Proportions

                               4 : 6 :: 6 : x

                                x = (6 x 6) / 4

                               x = 9

Perimeter = 2(base) + 2(height)

                 = 2(9) + 2(6)

                 = 18 + 12

                 = 30 in

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
