Allushta [10]

Answer:

67.5 degrees

Step-by-step explanation:

The piece that isn't marked with xs is 90 degrees marked by the square symbol representing a right angle.

Full circle = 360 degrees

360 degrees - 90 degrees = 270 degrees

Now, if we add all the like terms we have 4 x's in total. This is becauswe 3x + another x = 4x.

So, we need to divide 270 by 4. We get 67.5 degrees.

Hope this helps!

The graph shows the linear relationship between the height of a plant (in centimeters) and the time (in weeks) that the plant ha
Snezhnost [94]
You did not include the graph.

Searching on internet I found a graph with which I can help you. I will solve the question using and so you can understand the problem and solve with the real graph.

1) The slope of line given the graph is calculated as:

slope = run / rise = Δy / Δx = constant.

2) So, you can choose any two points to calculate the slope.

3) Uisng the points (50,20) and (30,10) you get:

slope = [ 20 - 10] / [50 - 30] = 10 / 20 = 1/2

4) Note that that means that the plant grows 1 cm in 2 days

5) The rate of change is 1cm / 2 weeks.

With this you know how to calculate the slope, which is the same rate of change, and the meaning of it, which permits to answer the question from the complete statement and graph.

  3. Determine the area of the square brick
  4. Multiply the cost of the brick by the area

1 yards = 3 foot

5 x 3 = 15 foot

Area of a rectangle = length x breadth

15 x 10 = 150 ft^2

Cost = 150 x 4 = $600
