The question says “The image shows the front of Bob’s barn.Bob plans on painting the front of his barn,not including the doors o

AleksandrR [38]

Bob need to paint 205 square feet.

Solution:

Length of the door = 7 ft

Breadth of the door = 5 ft

Area of the door = length × breadth

= 7 × 5

= 35

Area of the door = 35 ft²

The given image is a trapezoid.

Top base = 12 ft

Bottom base = 20 ft

Area of the trapezoid = $\frac{1}{2} \times\text{sum of the parallel sides}\times\text{height}$

$$=\frac{1}{2}\times(12+20)}\times15$

$$=\frac{1}{2}\times 32\times15$

= 240

Area of the trapezoid = 240 ft²

Surface area to paint = Area of the trapezoid – Area of the door

= 240 ft² – 35 ft²

= 205 ft²

Hence Bob need to paint 205 square feet.

-6, -6) and (-2, -2)<br> Find the rate of change of the line that passes through the points.

Kamila [148]

Rate of change of line that passes through the given points is 1

Step-by-step explanation:

The ratio of vertical and horiontal changes is called the rate of change of a line. It is called slope which is denoted by m.

The formula for slope when (x1,y1) and (x2,y2) are the points on line is given by:

$m = \frac{y_2-y_1}{x_2-x_1}\\$

Given

(x1,y1) = (-6,-6)

(x2,y2) = (-2,-2)

Putting the values in the formula

$m = \frac{-2-(-6)}{-2-(-6)}\\=\frac{-2+6}{-2+6}\\=\frac{4}{4}\\= 1$

Rate of change of line that passes through the given points is 1
