58.50 dollars because 13.50 is 30% of $45 dollars so then you add $13.50 to $45.

Which sequence of transformations performed on shape I confirms the congruence of shape II and shape I?

vampirchik [111]

Answer:

Option D. a 180° rotation about the origin and then a translation left 8 units.

Step-by-step explanation:

See the attached figure_1

From the graph: Point A'(-12,-6) is the image of point A(4,6)

We will check which sequence of transformations is true:

A. a reflection across the y-axis and then a translation down 16 units

A(4,6) ⇒(-4,6)⇒(-4,-10) (Wrong sequence)

B. a 90° counterclockwise rotation about the origin and then a translation down 8 units

A(4,6) ⇒(-6,4)⇒(-6,-4) (Wrong sequence)

C. a 90° clockwise rotation about the origin and then a translation left 16 units

A(4,6) ⇒(6,-4)⇒(-10,-4) (Wrong sequence)

D. a 180° rotation about the origin and then a translation left 8 units

A(4,6) ⇒(-4,-6)⇒(-12,-6)A' (True sequence)

Note: the rules is the attached figure_2

The surface area formula for any sphere is 4(pi)(radius)^2

The radius is half of the diameter.

18.6 / 2 = 9.3

So, plug into the formula and solve.

4(3.14)(9.3)^2 = 1086.3 mm^2

Is the ratio 50 yards to 18 seconds a rate? Explain.

Anna11 [10]

Answer:50:18

Step-by-step explanation:

I think that this is the answer because 50 yards can be ran in 18 seconds so for every 18 seconds you get 50 yards
