Answer:

First, we need to know how to transform a figure when we want to rotate it.

  • If we rotate 90° clockwise, the transformation is from (x,y) to (y,-x), and counter clockwise is from (x,y) to (-y,x).
  • If we rotate 180° in any direction, the transformation is from (x,y) to (-x.-y).
  • If we rotate 270° clockwise, the transformation is from (x,y) to (-y,x). And counter clockwise is from (x,y) to (y,-x).

Now, we use these rules to match each statement with its right answer.

<h3>First statement: </h3>

The coordinates of D', if polygon ABCD rotates 90° counter clockwise to create A'B'C'D', would be (-2,2).

<h3>Second statement: </h3>

The coordinates of C'' , if polygon ABCD rotates 90° clockwise to create A''B''C''D'', would be (3,-1).

<h3>Third statement: </h3>

The coordinates of A''', if polygon ABCD rotates 180° clockwise to create polygon A'''B'''C'''D''', would be (4,-2).

<h3>Fourth statement: </h3>

The coordinates of B'', if polygon ABCD rotates 270° counterclockwise to create polygon A''B''C''D'', would be (4,2).

The answer is that if polygon ABCD rotates 90 counterclockwise to create a'b'c'd', then the coordinates of d will be at the location (-2, 2) and if the polygon ABCD rotates 180 clockwise to create a'b'c'd' the coordinate of A will become (3,-1).

lubasha [3.4K]

Answer:

Using the Pythagorean Theorem:

distance^2 = 72^2 + 65^2

distance^2 = 5,184 + 4,225

distance^2 = 9,409

distance = 97 yards

"round-trip" distance = 97 * 2 = 194 yards

Your little cousin will have a big animal-themed birthday party and you will help with the goody bags. Each bag will have a penc
Bas_tet [7]

Using the least common factor, it is found that:

  • a) 60 packages should be bought.
  • b) There will be 5 filled goody bags.

<h3>Least Common Factor:</h3>
  • The sizes of the packages are: 10, 6, 15 and 12.
  • To fill each bag and have no left-overs, the number of packages is the <u>least common factor</u> of these amounts.
  • The least common factor is found factoring the numbers into prime factors.

Item a:

10 - 6 - 15 - 12|2

5 - 3 - 15 - 6|2

5 - 3 - 15 - 3|3

5 - 1 - 5 - 1|5

1 - 1 - 1 - 1

Hence, lcf(10,6,15,2) = 2 x 2 x 3 x 5 = 60.

60 packages should be bought.

Item b:

Goody bags are in packages of 12, hence:

60/12 = 5.

There will be 5 filled goody bags.
