Answer:

Pythagorean Theorem. The Pythagorean theorem states that in any right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the legs of the right triangle. This same relationship is often used in the construction industry and is referred to as the 3-4-5 Rule.

You roll a six sided die and pull a card from a standard deck of 52 cards what is the probability that you roll a five and draw

m_a_m_a [10]

Answer:

1/24

Step-by-step explanation:

The probability of the dice landing with a 5 up is 1/6; that of drawing a heart is 13/52, or 1/4.

The joint probability of these two events (events happening simultaneously) is

(1/4)(1/6) = 1/24

I need help with these 2 questions

k0ka [10]

#1 w=9 because:
2w+2(2w+3)=60
2*2w=4w and 2*3=6
2w+4w+6=60
Then: 2w+4w= 6w
6w+6=60
I just tried each answer I knew it had to be 8 or 9
So I tried 8 and it didnt work then I tried 9 and it did
6*9= 54+6=60
w=9
#2 I have a picture for this one I worked it out on paper. Check out the photo for the answer :)
Hope this helps!
