7 0

Answer:

\frac{ {x}^{2} }{y(x - y)}  +  \frac{ {y}^{2} }{ - x(x - y)}

\frac{ {x}^{2} }{y(x - y)}  -  \frac{ {y}^{2} }{x(x - y)}

\frac{ {x}^{2}  \times x  -  {y}^{2}  \times y}{xy(x -y)}

\frac{(x - y)( {x}^{2}  + xy +  {y}^{2}) }{xy(x - y)}

\frac{ {x}^{2} + xy +  {y}^{2}  }{xy}

Two number cubes are rolled. What is the probability of rolling a sum of 9 or a sum that is even?
Murljashka [212]

Well I don't know !
Let's figure it out together.

Each cube can land in 6 different ways, so the total number
of possible results with two cubes is (6 x 6) = 36 .

Now we need to figure out how many of those 36 possibilities
meet your specifications ... either 9 or any even number.

Ways to make 9 :

3 . . . 6
6 . . . 3
4 . . . 5
5 . . . 4

Four ways to make 9.
____________________________

Ways to make an even number:

1 . . . 1
3 . . . 1
1 . . . 3
2 . . . 2
5 . . . 1
1 . . . 5
6 . . . 2
2 . . . 6
6 . . . 4
4 . . . 6
6 . . . 6

Eleven ways to make an even number.
_____________________

Total number of ways to succeed = (4 + 11) = 15 ways

So the probability of succeeding (rolling 9 or an even number)
is

               15 / 36  =  5 / 12  =  0.41666... =  (41 and 2/3) % .

They are congruent. I believe it is ASA because both triangles have two angles identical to the other triangle with shows it had equal angles so using process of elimination I’m assuming it’s ASA because it includes two angles lol

Distance
Slav-nsk [51]

Answer: 28 km

Step-by-step explanation: For the first 25 minutes, he drove 60 km/h. Since there is 60 minutes in an hour, we know that he drove 25 km. The rest of the journey is 15 minutes. 15 minutes is 1/4 of an hour, so get 1/4 of 12 km/h. This would be 3 km. Add 25 km and 3 km. The distance between the 2 malls is 28 km.
