Answer:

28 times

Step-by-step explanation:

On a fair die, the probability of rolling a 6, the only number greater than 5, is 1/6. So in 168 rolls of this die, Malachy can expect a 6 on 1/6 × 168, or 28 times.

In isosceles ΔABC, AC = BC, AB = 6 in, CD ⊥ AB, and CD = 3 in. Find the perimeter of the isosceles triangle.

Hoochie [10]

Answer:

Step-by-step explanation:

Consider the given triangle ABC, we have AC = BC, AB = 6 in, CD ⊥ AB, and CD = 3 in. Using ΔCDB, we have

$(CB)^{2}=(CD)^{2}+(DB)^{2}$

$(CB)^{2}=(3)^{2}+(3)^{2}$

$CB=\sqrt{9+9}$

$CB=\sqrt{18}in$

Therefore, $CB=CA=\sqrt{18}in$ (Given)

Now, Perimeter of an isosceles triangle is given By: 2a+b

⇒ $2(\sqrt{18})+6=2(4.24)+6=8.48+6=14.48in$

which is the required perimeter of isosceles triangle.
