Area is 360 meters squared Perimeter is 98 meters

Area:   split the shape into two, the top and the bottom.
 
the formula for area is length * width
so 9*10=90m^2
and 9*30= 270m^2
90+270= 360 meters squared

Perimeter: just add up all the sides

You can ignore a and b but can someone help me with c and d plz :)
katrin2010 [14]

Answer:

(below)

Step-by-step explanation:

c) the angles are in the interior on the same side of the transversal, making them supplementary

equation: 2x + 20 + 120=180 and then when solved you would get x =20

d) the angles are corresponding, which makes them congruent

equation: 3x + 10 = 100 and then when solved you would get x = 30

A contractor records all of the bedroom areas, in square feet, of a five-bedroom house as: 100, 100, 120, 120, 180 What is the v

The variance is the total of the squared distances of the given data from the mean. 

This can be calculated through the equation,
        
                            σ² = summation of X² / N  - μ²

where σ² is the variance X's are the data, N is the number of terms, and μ is the mean.

   summation of X² = 100² + 100² + 120² + 120² + 180² = 81200
                          N = 5
                                        μ = (100 + 100 + 120 + 120 + 180) / 5
                                         μ = 124

Substituting these values to the equation for variance,
                                 
                              σ² = (81200/5) - 124² = 864

Thus, the variance is equal to 864.

Three functions are given below: f(x), g(x), and h(x).
Rzqust [24]

Answer: The axis of symmetry is x=1.

Explanation:

The given function is,

g(x)=5x^2-10x+7

The degree of the equation is 2.  SInce it is a quadratic function therefore the graph of the function is a parabola.

The axis of symmetry of a parabolic function f(x)=ax^2+bx+c is a vertical line,

x=-\frac{b}{2a}

Since the value of a is 5m b is -10 and c is 7, So the axis of symmetry is,

x=-\frac{(-10)}{2(5)}

x=\frac{10}{10}

x=1

Therefore, the axis of symmetry is x=1.
