A square of the side lenght of 6cm has the same area as this rectangle . find the perimeter of the rectangle.
Aleksandr-060686 [28]

Answer:

The perimeter of the rectangle is 26 cm

Step-by-step explanation:

First find the area of the square by multiplying 6 by itself

A = 6 cm * 6 cm = 36 sq cm

Since the rectangle has the same area as the square, we can say that w * 9 = 36 sq cm

w * 9 = 36

Divide both sides by 9 to isolate the variable, w

w * 9 / 9 = 36 / 9

w = 4 cm

The width of the rectangle is 4 cm so now we just use that to find the perimeter of the rectangle

P = 2(9) + 2(4) = 26 cm

What is the probability of drawing two aces in a row from a deck of 52 cards, replacing the first card and reshuffling the deck?
sineoko [7]

Answer:

1/169

Step-by-step explanation:

There are 4 aces in a deck of 52.

The probability that the first card is an ace is 4/52.

Since the card is replaced, the probability that the second card is an ace is also 4/52.

The total probability is (4/52) (4/52) = 1/169.
