Here is my theory. I did not use the Pythagorean Theorem. I used basic cross multiplication.
z = 25
t = 24
Answer:
Here
Step-by-step explanation:
length = x
width = 2x - 3
Perimeter = 2length + 2 width
2x + 2(2x - 3) = 42
2x + 4x - 6 =42
6x - 6 = 42
Add 6 to both sides
6x = 48
Divide both sides by 6
x = 8
Length = 8 inches
Width = 2(8) - 3 = 16-3 = 13 inches
Answer:
Step-by-step explanation:
given that two cards are drawn, without replacement, from a standard 52-card deck.
a) Both cards are red
Here there are 26 red cards and 52 total cards.
Probability =
b) Both cards are the same color
i.e. either both are red or both are black
Hence probability = twice of part a
=
c) The second card is a queen, given that the first card is an ace.
If first card is an ace remaining are 51 cards with 4 queens\
So prob = 4/51
Answer:
none
