There are two black queens in a standard deck, so the probability is 2/52 or 1/26.

If instead you know you pulled a black card from the deck and you’re wondering what the probably is that it’s a queen, then it’s 2/26, since there are still 2 black queens, but only 26 black cards.

Using x as the variable, write a formula to find the perimeter of the figure. Use the formula to find the perimeter. a regular d

Mamont248 [21]

Answer:

c. 12x; 111 cm

Step-by-step explanation:

The regular dodecagon has 12 sides. Each side has a length of x=9.25 cm, and we know that the perimeter of the figure is the sum of the lengths of all the sides: Therefore, since we have 12 sides, the perimeter will be given by the product between the length of each side, x, and the number of sides, 12:

$p=12 \cdot x$

and if we substitute x = 9.25 cm, we find

$p=12 \cdot 9.25 cm=111 cm$

Suppose a, b, and c are all negative numbers. How do you find the distance between the points (a,b) and (a,c)?

Alex787 [66]

Answer:

Step-by-step explanation:

Let's say if b = -2 and c = -3

-2-(-3) = 1 that would be the distance between them. If it was D then you would need absolute value.

Answer:

Congruent and isometries.

Step-by-step explanation:

Congruent meaning the shape is still the same size and shape

(which is true because translations and rotations don't change size or shape)

And isometries because it is one way of mapping points to a different location.
