Answer:

The correct option is 4.

Step-by-step explanation:

Let the number of sheep be x and the number of chickens be y.

It is given that there are total 16 animals.

x+y=16           .... (1)

The number of chickens, y, is 4 less than the number of sheep, x.

y=x-4            .... (2)

Using (1) and (2), we get

x+(x-4)=16

2x-4=16

Add 4 on both the sides.

2x=16+4

2x=20

Divide both sides by 2.

x=10

Put x=10 in equation (1).

10+y=16

Subtract 10 from both the sides.

y=16-10

y=6

The ordered pair (10,6) represents the number of chickens and sheep. Therefore the correct option is 4.

Answer:

Area=76.56 square feet

Step-by-step explanation:

area of a rectangle =base*height = 5ft*8ft= 40 square feet

area of a triangle=(base*height)/2 =(4ft*4ft)/2= 8 square feet

area of a square=base*height =4ft*4ft= 16 square feet

area of a circle =\pi* r^{2}[/tex]=3.14*2^{2}= 12.56 square feet

r = radius

Total area=(40+8+16+12.56)square feet

Total area=76.56square feet
