the backyard if a new home is shaped like a trapezoid with a height of 46 ft and bases of 73 ft and 114 ft. what is the cost of
Doss [256]

Answer:

$989.23

Step-by-step explanation:

The cost will be the product of the area in square feet and the cost per square foot.

The area of a trapezoid is given by the formula ...

... A = (1/2)(b1 +b2)h . . . . . where b1 and b2 are the base lengths, h is the height

Filling in the given information, the area is ...

... A = (1/2)(73 ft +114 ft)(46 ft) = 4301 ft²

Since each square foot costs $0.23, this number of square feet will cost ...

... (4301 ft²)×$0.23/ft² = $989.23

The landscaper will charge $989.23 to put sod on the backyard.

Find the sum of the measures of the intereor angles of each convex polygon.
serious [3.7K]

Step-by-step explanation:

To find the sum of the measures of the intereor angles of each convex polygon

we using formula

  • (x - 2)180°
<h3>#4</h3>

we can put the value of x is 54

then,

  • \longrightarrow \:  (54 - 2) \times 180°

  • \longrightarrow \: 52 \times 180°
  • \longrightarrow \: 9360°
<h3>#5</h3>

we can put the value of x is 19

then,

  • \longrightarrow \: (19 - 2) \times 180°
  • \longrightarrow \: 17 \times 180°
  • \longrightarrow \: 3060°

#6

we can put the value of x is 292

then,

  • \longrightarrow \: (292 - 2) \times 180°
  • \longrightarrow \: 290 \times 180°
  • =》 52200°

#7

we can put the value of x is 5

then ,

  • \longrightarrow \: (5 - 2) \times 180°
  • \longrightarrow \: 3 \times 180°
  • =》 540°

A potter is creating a design for a red-colored urn. He starts with the design shown on the coordinate grid.
DaniilM [7]
Given:

the design is to be rotated about the line x = 1 to produce the shape of the urn. 

To generate a design for the urn, we need to draw a vertical line at x = 1, this will be our axis of rotation (or the basis for our mirror). We will use the mirror principle in making our design. So we will either draw half the shape of the urn at the left or right side of the axis of rotation.
