Answer:

5 units apart.

Step-by-step explanation:

You can figure this out by:

a- You can count the squares in between the two points.

                                               OR

b- You would find the absolute value of both the x  values and add them together to see the overall length from each other that they are.

So when you complete either one of these tactics you would get an answer of  5 units apart.

Answer:

1/2

Step-by-step explanation:

Here you utilize the formula of slope which is  m  = y2-y1/x2 -x1

Step-by-step explanation:

well we use the distance formula

[tex]\sqrt{(4^{2}+(-4)^2 )+(3^2+(-3)^2)}\\ =\sqrt{32+18} \\=\sqrt{50}\\ =5\sqrt{2}[/tex]

so that's the length of the radius

The length of the radius of a circle whose center is at (3,4) and passes through (-3,-4) is given by 10 units.

Radius of circle is the fixed distance between center and any point lies on the circumference of the circle.

Two distance between two points (a,b) and (c,d) is given by [tex]=\sqrt{(c-a)^2+(d-b)^2}[/tex]

Here in the given problen we have to find the length of the radius of a circle whose center is at the point (3,4) and passes through the point (-3,-4).

So basically we have to find the length between the points (3,4) and (-3,-4).

The radius of circle is given by

[tex]=\sqrt{(-3-3)^2+(-4-4)^2}[/tex]

[tex]=\sqrt{(-6)^2+(-8)^2}[/tex]

[tex]=\sqrt{36+64}=\sqrt{100}=10[/tex]

Hence the length of the radius of the circle is given by 10 units.

Answer:

The answer is below

Step-by-step explanation:

From the diagram attached, to find the length of side AB, we need to use Pythagoras theorem on the right triangles. We can see that AB is the base of the two right triangle.

For the first right triangle with hypotenuse of 13 and height of 12, let x be the base, therefore using hypotenuse:

13² = 12² + x²

169 = 144 + x²

x² = 169 - 144

x² = 25

x = √25 = 5

For the second right triangle with hypotenuse of 15 and height of 12, let y be the base, therefore using hypotenuse:

15² = 12² + y²

225 = 144 + y²

y² = 225 - 144

y² = 81

y = √81 = 9

The length of AB = x + y = 9 + 5 = 14 unit

Since for a square all the sides are equal, therefore the length of each side of the square ABCD is 14 units.

In triangle ADC, the hypotenuse = AC, AD = DC = 14 unit. Using Pythagoras:

AC² = AD² + DC²

AC² = 14² + 14²

AC² = 196 + 196 = 392

AC = √392 = 19.8

The length of its diagonal is about 19.8 units

Step-by-step explanation:

Para calcular de cuántas maneras se puede seleccionar x elementos de un grupo de n elementos podemos usar la siguiente fórmula:

[tex]nCx=\frac{n!}{x!(n-x)!}[/tex]

Si vas a elegir 3 personas de entre 6 matrimonios y dos miembros de la misma pareja no pueden ser elegidos, entonces podemos decir que se está eligiendo 3 matrimonios y en cada matrimonio se está eligiendo un representante.

Entonces, podemos calcular de cuántas maneras se puede escoger 3 matrimonios de los 6, así:

The first unit price ($0.30/balloon) beats the second ($0.32/balloon).

Step-by-step explanation:

4 packages of 15 balloons for $18 works out to 1 package of 15 balloons for $18/4, or $4.50.  That'd be

$4.50

---------------- = $0.30/balloon.

15 balloons

Next:  5 packages of 10 for $16 works out to 1 package of 10 for $16/5, or

1 package of 10 for $3.20.  That'd be

  $3.20

----------------- = $0.32/balloon

10 balloons

The first unit price ($0.30/balloon) beats the second ($0.32/balloon).

If Bella understands the math involved in finding unit costs and actually does the work prior to buying anything, then I'm comfortable with her buying habits.

Both deals are almost same.

We have a girl Bella who is buying balloons for a back to school celebration. She sees there are 4 packages of 15 balloons for $18 and 5 packages of 10 balloons for $16.

We want to know which is a better deal with appropriate reason. We have to morally investigate on the basis of our thinking whether or not Bella's buying habits are good or not.

The cost of 1 balloon will be =  [tex]\frac{x}{n}[/tex]  (in dollars)

Now, according to question -

Case 1 :

The total number of balloons are 15 x 4 = 60 balloons.

The cost of these 60 balloons is $ 18.

Cost of 1 balloon = [tex]\frac{18}{60}[/tex] = $ 0.3

Case 2 :

The total number of balloons are 10 x 5 = 50 balloons.

The cost of these 60 balloons is $ 16.

Cost of 1 balloon = [tex]\frac{16}{50}[/tex] = $ 0.32

It can be concluded that the both deals are almost same and i think that it is okay to spend a bit amount of money for a back to school party.

Answer:

Step-by-step explanation:

Let the three numbers be a-d, a, a+d being a series in AP.

The sum of the three numbers is 24 = a-d+ a+ a+d = 3a

Thus a = 8.

Now a-d-1, a-2, a+d form a GP. It means, the common ratios should be equal or the middle term should be the Geometric Mean of the first and third terms, or

(a-d-1)(a+d) = (a-2)^2 or

(8-d-1)(8+d) = (8-2)^2, or

(7-d)(8+d) = 36, or

56 -8d +7d -d^2 = 36, or

56 -8d +7d -d^2 - 36 = 0, or

d^2 +d -20 = 0

(d+5)(d-4) = 0

Thus d = -5 or 4

So the AP is 13,8,3 or 4,8,12

Check: 13,8,3 in AP becomes (13–1), (8–2), 3 = 12, 6, 3 which is a GP with r = (1/2)

4,8,12 in AP becomes (4–1), (8–2), 12 = 3, 6, 12 which is a GP with r =2

Step-by-step explanation:

Just took the test and did calculations. 100% correct

After solving for both variables, you find that each bus can hold 59 students and each van can hold 18 students.

Step-by-step explanation:

You can find the amount of students each vehicle can carry by representing the two scenarios in equations.

You are trying to find how many students will fit in each bus or van, so the two variables used will be "b" to represent how many students can fit in a bus and "v" to represent how many students can fit in a van.

High school A used 1 van and 6 buses, so there will be 1"v" and 6"b" for 372 students.

High school B used 4 vans and 12 buses, so there will be 4"v" and 12"b" for 780 students.

Now, represent these in equations:

[tex]v+6b = 372\\4v + 12b = 780[/tex]

We can use substitution to solve this system:

[tex]v + 6b = 372[/tex] can be rewritten as [tex]v = 372 - 6b[/tex] after subtracting 6b from both sides. You can then substitute this new value of "v" into the other equation to solve for "b":

[tex]4(372-6b) + 12b = 780\\1488 - 24b + 12b = 780\\1488 - 12b = 780\\-12b = -708\\b = 59[/tex]

After solving for b, you can then substitute the new value of b into the other equation to find the value of v:

[tex]v + 6(59) = 372\\v + 354 = 372\\v = 18[/tex]

After solving for both variables, you find that each bus can hold 59 students and each van can hold 18 students.

Answer:

             Van: 18,  Bus: 59

Step-by-step explanation:

b   - number of students that bus can carry

v   - number of students that van can carry

6•b + 1•v = 372     -  students from A

6b + v = 372    ⇒  v = 372 - 6b

12•b + 4•v = 780     -   students from B

12b + 4(372 - 6b) = 780

12b + 1488 - 24b = 780

- 12x = - 708

   b = 59    

v = 372 - 6•59 = 372 - 354 = 18
