The probability of getting a 2 and 3 in two cubes is \frac{1}{36}

<u><em>Explanation</em></u>

Total face values in each number cube is  6.

In first cube, probability of  getting a 2 is = \frac{1}{6}

and also in the second cube, probability of getting a 3 is = \frac{1}{6}  

So, the probability of getting a 2 and 3 in two cubes = \frac{1}{6}*\frac{1}{6}= \frac{1}{36}

Each side of a square is increased 3 inches. When this happens, the area is multiplied by 25. How many inches in the side of the
grin007 [14]

Answer:

s = 0.75 inches

Step-by-step explanation:

Let s = side length of the original square

s + 3 = side length of the new square

Area of a square = s²

A = s²

A = (s+3)²

A = s² + 6s + 9

Area multiplied by 25 = 25 * s²

So,

s² + 6s + 9 = 25s²

25s² - s² - 6s - 9 = 0

24s² - 6s - 9 = 0

8s² - 2s - 3 = 0

a = 8

b = -2

c = -3

s = -b ± √b² - 4ac / 2a

= -(-2) ± √(-2)² - 4(8)(-3) / 2(8)

= 2 ± √4 - (-96) / 16

= 2 ± √100 / 16

= 2 ± 10/16

s = 2 + 10/16 or 2-10/16

= 12/16 or -8/16

= 0.75 or -0.5

side length can not be negative

Therefore, s = 0.75

A = s²

A = (0.75)²

= 0.5625

A = (s+3)²

= (0.75+3)²

= 3.75²

= 13.95

How many triangles exist with the given side lengths? 7 in, 7 in, 7 in A. No triangle exists with the given side lengths. B. Mor
Kazeer [188]

C. Exactly one unique triangle exists with the given side lengths.

<u>Step-by-step explanation:</u>

A triangle consists of three sides, depending on the measurement of the sides, naming of the triangles can be varied.

If all the three sides are equal in length, it is said to be an equilateral triangle. Only one triangle can be formed using the measures of 7 in, 7 in, 7 in, that is all the three sides are same in measurement of 7 inches.

So, Exactly one unique triangle can be produced with the given side lengths.
