Answer:

22 hens and 78 sheep

Step-by-step explanation:

Let the number of hens = x

Number of sheep = y

Total heads = 100

x +  y = 100      --------------------(I)

 x = 100 - y

Number of legs of 'x' hen = 2*x = 2x

Number of legs of 'y' sheep = 4*y = 4y

total legs = 356

2x + 4y =  356 -----------------------(II)

Substitute x = 100 -y in equation (II)

2(100 - y) + 4y = 356

2*100 - 2*y + 4y = 356

200 - 2y + 4y    = 356 {Combine like terms}

        200  + 2y = 356          {Subtract 200 from both sides}

                   2y = 356 - 200

                  2y = 156       {Divide both sides by 2}

                    y = 156/2

                  y = 78

Plugin  y = 78 in equation (I)

x + 78 = 100

       x = 100 - 78

       x = 22

22 hens and 78 sheep

Answer:

74 + 6x + 8 = 180

6x + 82 = 180

6x = 180 - 82

6x = 98

x = 98/6

x = 16.3

An equation for the pictured graph and the equation for the pictured graph in factored form is: y = rs - r - s + 1.

Let's assume the equation for the graph in factored form is: y = a(x - r)(x - s), where 'a' is a constant and 'r' and 's' are the roots of the equation (x-intercepts of the graph). Since we are given that the graph passes through the points (0, -2) and (1, 0), we can use this information to find the values of 'r' and 's.'

Using the point (0, -2):

When x = 0, y = -2.

We can substitute these values into the equation:

-2 = a(0 - r)(0 - s)

Simplifying, we get: -2 = a(-r)(-s) or -2 = ars.

Using the point (1, 0):

When x = 1, y = 0.

Substituting these values into the equation:

0 = a(1 - r)(1 - s)

Simplifying, we get: 0 = a(1 - r)(1 - s).

Now, we have two equations:

-2 = ars (Equation 1)

0 = a(1 - r)(1 - s) (Equation 2)

From Equation 1, we can solve for 'a' in terms of r and s:

a = -2 / rs.

Now, substitute this value of 'a' into Equation 2:

0 = (-2 / rs)(1 - r)(1 - s).

To make further progress, we can divide both sides by -2:

0 = (1 / rs)(1 - r)(1 - s).

Next, to eliminate the fractions, multiply both sides by rs:

0 = (1 - r)(1 - s).

Finally, expand the right side of the equation:

0 = 1 - s - r + rs.

The equation for the pictured graph in factored form is:

y = rs - r - s + 1.

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Shape A

has b = 9.6 and h = 5.8, then

A = 0.5 × 9.6 × 5.8 = 27.84 m²

Shape B

has b = 11.8 and h = 7.2 , then

A = 0.5 × 11.8 × 7.2 = 42.48 m²

Answer:

Shape A = 55.68

Answer:

2200 baseball cards

Step-by-step explanation:

Step-by-step explanation:

perimeter - 16cm

length - 5cm

find breadth,

perimeter of rectangle = l × b

16cm = 5 × b

b = 16/5

b = 3.2 cm

Step-by-step explanation:

Given

perimeter (P) = 16 cm

Length(L) = 5 cm

breadth (b) = ?

We know

P = 2 (L + b)

16 = 2 ( 5 + b)

16 = 10 + 2b

2b = 16 - 10

2b = 6

b = 6 / 2

b = 3 cm

Answer:

telephone pole height = 480ft

Step-by-step explanation:

Assume that the shadow that an object casts is proportional to the height of the object. Then one can form the ratio:

[tex](shadow : height)[/tex]

Making the assumption that this ratio is proportional for all objects in this given scenario, then one can say that the ratio of the height of the man and his shadow is equal to the ratio of the height of the telephone pole and its shadow:

(man's height) : (man's shadow) = (pole's height) : ( pole's shadow)

Substitute:

6ft : 4ft 6in = (telephone pole hiehgt) : 30ft

Convert to inches (since it is all in the same unit now, one's doesn't need to write the unit anymore):

72 : 54 = (telephone pole height) : 360

Simplify:

4 : 3 = (telephone pole height) : 360

Now solve, use cross products:

3(telephone pole height) = 1440

Inverse operations,

3(telephone pole height) = 1440
