Answer:

The length of the shortest side of the triangle is 10 units.

Step-by-step explanation:

Let <em>a</em> be the shortest side of the isosceles triangle and <em>b</em> be the two congruent sides.

The congruent sides <em>b</em> are each one unit longer than the shortest side. Hence:

b=a+1

The perimeter of the isosceles triangle is given by:

\displaystyle P_{\Delta}=b+b+a=2b+a

This is equivalent to the perimeter of a square whose side lengths are two units shorter than the shortest side of the triangle. Let the side length of the square be <em>s</em>. Hence:

s=a-2

The perimeter of the square is:

\displaystyle P_{\text{square}}=4s=4(a-2)

Since the two perimeters are equivalent:

2b+a=4(a-2)

Substitute for <em>b: </em>

<em />2(a+1)+a=4(a-2)<em />

Solve for <em>a</em>. Distribute:

2a+2+a=4a-8

Simplify:

3a+2=4a-8

Hence:

a=10

The length of the shortest side of the triangle is 10 units.

In a game the player wins if you roll a six on a number cube is the number cube is rolled 18 times then what is a reasonable pre
skad [1K]

Answer:

14 rolls

Step-by-step explanation:

Each result 1-6 has an equal chance. The probability is the number of chances divided by the total number. The total number of options is 6 since it is a six sided cube. Rolling a 6 which is represented once is a 1 out 6 likelihood.

1 out of 6 is 1/6 = 0.17 = 17%.

This means that 83% of the time will be unsuccessful of 18 rolls.

0.83(17)= 14.11
