Answer:

d = \sqrt{65}\text{ units}

Step-by-step explanation:

Let (x_1,x_2) and (y_1, y_2) be the two points.

We have to find the distance between the two points.

The distance Formula:

d = \sqrt{(x_1 - y_1)^2 + (x_2 - y_2)^2}

Here, we are given (x_1,x_2) = (5,1) and  (y_1, y_2)  = (9,-6)

Then, the distance between these two points is given by:

d = \sqrt{(5 - 9)^2 + (1- (-6))^2}

d = \sqrt{(-4)^2 + (7)^2}

d = \sqrt{16 + 49}

d = \sqrt{65}

Thus, the distance between the given point is \sqrt{65}\text{ units}.

So the distance formula: d = rad (x2 - x1)^2 + (y2 - y1)^2
it doesn't matter what order you do, you just have to make sure it's a y coordinate for y and an x coordinate for x.
rad (9-5)^2 + ((-6)-1)^2
rad 4^2 + (-7)^2
rad 16 + 49
rad 65

En una clase, 1/3 de los estudiantes eligieron estudiar español como segundo lenguaje vivo. 1/9 eligió italiano, el resto eligió
max2010maxim [7]

Answer:

5/9

12

Step-by-step explanation:

La clase entera es 1.

1/3 estudian español.

1/9 estudian italiano.

1 - 1/3 - 1/9 estudian alemán.

1 - 1/3 - 1/9 = 9/9 - 3/9 - 1/9 = 5/9

<em>5/9 de los estudiantes estudian alemán.</em>

n = numero total de estudiantes en la clase.

5/9 n = 15

9/5 * 5/9 * n = 15 * 9/5

n = 27

Hay 27 estudiantes en la clase.

27 - 15 = 12

<em>12 estudiantes no estudian alemán.</em>

Which is the better buy, 7 pounds for $8.47 or 9 pounds for $11.07?
wel
Let us take the case of 7 pounds for $8.47 first.
7 pounds of a product costs = 8.47 dollars
Then
1 pound of the same product will cost = (8.47/7) dollars
                                                             = 1.21 dollars
Now let us take the case of 9 pounds for $11.07
9 pounds of a product costs = 11.07 dollars
Then
1 pound of the same product will cost = (11.07/9) pounds
                                                             = 1.23 dollars
So from the above deductions we can see that 9 pounds for $11.07 is a better buy than 7 pounds for $8.47. I hope the procedure is clear enough for you to understand. In future you can use this method for solving similar problems.
