Answer:

105.12 ft²

Step-by-step explanation:

Area of the figure = area of the rectangle + area of half a circle

= L*W + ½(πr²)

Where,

L = 10 ft

W = 8 ft

r = ½ of 8 = 4 ft

π = 3.14

Plug in the values

Area = 10*8 + ½(3.14*4²*)

Area = 80 + 25.12

Area = 105.12 ft²

Answer:

(-60/11,111/11)

Step-by-step explanation:

Solving simultaneously, 4x - 3y=6   -3(6x + y=42)   then it becomes, 4x - 3y=6

-18x - 3y= 126 subtracting the two equations,   22x= -120, x= -60/11 and y = 111/11

.

Answer:

(-0.5, 1)

Step-by-step explanation:

4x - y = -3    ----------------------(I)

-6x + 3y = 6 -------------------(II)

Multiply equation (I) by 3 and then add. So, y will be eliminated and you can find the value of x.

(I) * 3         12x - 3y = -9

(II)             -6x + 3y = 6          {Now, add}

                6x          = -3

                          x = -3/6

                          x = - 0.5

Plug in x = -0.5 in equation(I)

4*(-0.5) - y = -3

- 2   - y = -3

     -y   = - 3 + 2

    -y   =  -1

     y = 1

Step-by-step explanation:

The line that divides the kite into two equal part is its line of symmetry, which is BD. Thus, the statement that must be true of the given kite is: OPtion A. AB ≅ CB

A line of symmetry when drawn through a shape divides it into two equal parts with the same characteristics. So that a kite always have 1 line of symmetry. A kite is a quadrilateral with a line of symmetry and the sum of its internal angles to be [tex]180^{o}[/tex].

Considering the kite in the question, its line of symmetry is BD.

So that:

ΔABD ≅ ΔCBD

In that case,

Therefore, the statement that must be true about the kite shown is:

Option A. AB ≅ CB (symmetrical property of a given shape)

D. 12, 15, 25

Step-by-step explanation:

The triangle leg rule states that the smaller two lengths must add up to be greater than the largest length.

This means that the first two values must add up to be greater than the final value.

12 + 15 = 27

27 > 25

So, your answer is D

choice #6)  2/3

Answer:

Step-by-step explanation:

12x<96. divide both sides by 12

x<8

So it would be a leftward arrow with a hollow dot at 8 because 8 is not included because x is ‘less tha’ 8

Answer:

x < 8

see attached image

Step-by-step explanation:

Start by dividing both sides by 12 (which is a positive number, so the inequality symbol stays as it is)

x < 96 / 12

x < 8

then graph it as the left side of the x-axis to the point 8,   NOT including this point (use an empty dot as shown in the attached image)
