Answer:
81
Step-by-step explanation:
9 x 9 = 81
So, 81 is the perfect square.
These are both independent events because 1 spin does not effect the other.
P(1st spin is 3) = 1/8
P(2nd spin is 7) = 1/8
P(both) = 1/8 * 1/8 = 1/64
Answer:
6.9
Step-by-step explanation:
Let x be the length of the remaining side.
By the Pythagorean theorem,
4² + x² = 8²
x² = 8² - 4² = 48
x = √48 = 4√3 ≅ 6.9
Answer:
