280. You add all the numbers up, and divide by how many numbers you have. (320+280+280+250+270)/5.
Essentially, what you are doing is taking each individual point and moving that point as specified.
So, for example, problem 1 has coordinates as follows: (be aware: I have terrible eyesight, so the points are being named based on what I think the letters are).
X: located at (2,0), move 1 unit left, new location: (1,0)
G: located at (4,0), move 1 unit left, new location: (3,0)
Q: located at (2,-2), move 1 unit left, new location: (1,-2)
C: located at (3,-4), move 1 unit left, new location: (2,-4)
Now, just plot the new shape.

Answer:
It will cost $256542 to prepare the field for next weeks match.
Step-by-step explanation:
The maximum dimensions of a field according to FIFA rules is 110 m by 75 m.
So, the maximum area of a field is (110 × 75) = 8250 square meters.
Now, 1 square meters is equivalent to 1.196 square yards.
So, the maximum area of a field is (8350 × 1.196) = 9867 square yards.
Now, given that it costs to make ready each square yard of a full-size FIFA field, $26 before each game.
Therefore, it will cost $(26 × 9867) = $256542 to prepare the field for next week's match. (Answer)
<u>7.1 cm long is the arc</u><u> intersected by a central angle .</u>
What is length of an arc?
- The arc length of a circle can be calculated with the radius and central angle using the arc length formula.
- Length of an Arc = θ × r, where θ is in radian. Length of an Arc = θ × (π/180) × r, where θ is in degree.
Given,
Central angle = π / 2
radius = 4.5 cm
we apply formula of length of arc.
length of the arc = angle × radius
= (π/2) × (4.5 cm)
Now put value of π = 3.14
length of the arc = (3.14 / 2) × (4.5) cm
= 7.065 cm ≈ 7.1 cm
Therefore, 7.1 cm long is the arc intersected by a central angle .

The area of a triangle can be calculated through the equation,
A = bh / 2
where A is area, b is base, and h is height.
Substituting the known values from the given above to the equation
A = (14 in)(6 in) / 2 = 42 in²
Since, there are five of these triangles, the total area is,
total area = 5(42 in²) = 210 in²
Thus, the total area of the plywood needed is 210 in².
