Answer:
A - 5 square root of 3
Step-by-step explanation:
Take one of the triangles and use the pythagorean theorem. A^2 + B^2 = C^2
Hence,
5^2 + x^2 = 10^2
25 +x^2 = 100
25 +x^2 -25 = 100-25
x^2 = 75
Take the square root of both sides. . .
x = 5 square root of 3
so about 53 kids didn't have costumes.
Answer:
2/13 or 15.38%
Step-by-step explanation:
Number of Aces in a deck = 4
Number of 7s in a deck = 4
Number of cards in a deck = 52
Probability of A or 7 = (4 Aces + 4 Sevens) / 52 cards 8 cards / 52 cards
This simplifies to 2/13 or 15.38%
