Pentagon abcde is shown on the coordinate plane below.
if pentagon abcde is rotated 180° around the origin to create pentagon a’b’c’d’e’, what is the ordered pair of point a’?
(2, -4)
(-4, -2)
(-2, -4)
(4, 2)

(2, −4)

Step-by-step explanation:

Just took the test :)

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
