The picture shows a circle divided into 8 equal wedges which are rearranged. The radius of the circle is r and its circumference is 2 $$2\pi r$$ . How does the picture help to explain why the area of the circle is $$\pi r^2$$ ?

By showing that the rearranged wedges form a shape similar to a parallelogram with base $$\pi r$$ and height $$r$$ , whose area is $$\pi r^2$$ .

By showing that the rearranged wedges form a square with side $$r$$ , whose area is $$r^2$$ .

By showing that the rearranged wedges form a triangle with base $$2\pi r$$ and height $$r$$ , whose area is $$\pi r^2$$ .

By showing that the rearranged wedges form a rectangle with base $$r$$ and height $$2\pi r$$ , whose area is $$2\pi r^2$$ .

Select all the statements that must be true for any scaled copy Q of Polygon P.

If the scale factor between P and Q is 1/5, then each side length of P is multiplied by 1/5 to get the corresponding side length of Q.

If the scale factor is 2, each angle in P is multiplied by 2 to get the corresponding angle in Q.

The side lengths are all whole numbers.

The angle measures are all whole numbers.

Both equations represent the same story.

Neither equation represents any story.

37. (7.6.5 PP3) Here are two stories: - A family buys 6 tickets to a show. They also each spend $3 on a snack. They spend $24 on the show. - Diego has 24 ounces of juice. He pours equal amounts for each of his 3 friends, and then adds 6 more ounces for each. Here are two equations: - 3(x + 6) = 24 - 6(x + 3) = 24 c. What is the solution to each equation? A) x = 2 for 3(x + 6) = 24 and x = 1 for 6(x + 3) = 24 B) x = 2 for 6(x + 3) = 24 and x = 1 for 3(x + 6) = 24 C) x = 3 for both equations D) x = 4 for both equations

x = 2 for 3(x + 6) = 24 and x = 1 for 6(x + 3) = 24

x = 2 for 6(x + 3) = 24 and x = 1 for 3(x + 6) = 24

37. (7.6.5 PP3) Here are two stories: - A family buys 6 tickets to a show. They also each spend $$3 on a snack. They spend $$ 24 on the show. - Diego has 24 ounces of juice. He pours equal amounts for each of his 3 friends, and then adds 6 more ounces for each. Here are two equations: - 3(x + 6) = 24 - 6(x + 3) = 24 Which equation matches the family's situation, and which matches Diego's situation?

6(x + 3) = 24 matches the family; 3(x + 6) = 24 matches Diego.

3(x + 6) = 24 matches the family; 6(x + 3) = 24 matches Diego.

Both equations match the family.
