The average speed is:

Step-by-step explanation:
The average speed equation is given by:

Were:
- Δx is the displacement (225 miles)
- Δt is the change in time (3 hours)
Then we have:

Answer:
42 cm²
Step-by-step explanation:
The attachment shows a couple of ways the figure can be considered.
a) Left and Right rectangles that are 5 cm high and 3 cm wide, together with a central rectangle that is 3 cm high and 4 cm wide. Then the total area is ...
5×3 + 3×4 + 5×3 = 15 + 12 + 15 = 42 . . . . cm²
__
b) An enclosing rectangle that is 5 cm high and 10 cm wide with a cut-out that is 2 cm high and 4 cm wide. Then the total area is ...
5×10 -2×4 = 50 -8 = 42 . . . . cm²
__
The area of the irregular figure is 42 cm².
Parallelogram area = base * height
30 = 10 * height
height = 3
Sine Parallelogram Angle = height / side
Sine (Angle) = 3 / 6
Sine Angle = .5
Angle = 30 degrees
To find the decimal equivalent of the fraction, divide the top number by the bottom one.
7/8 = 0.875
That's bigger than 0.825 .
The standard form of a circle is:

Where
(h, k) is the center
r is the radius
Since the center is (1, 1), we can write:

EG (hypotenuse of the right triangle) is the radius of the circle. Thus, we can say >>>

The correct answer is
B
