Since no specific method was stipulated the combinations of three different regions from the 10 possible regions that would result inexactly 50 points is Zero.

The possible scores are given below:

10 10 10, 10 10 5, 10 5 5, 5 5 5, 10 10 1, 10 1  1, 10 5 1, 5 5 1, 5 1 1 and 1 1 1.

The sum of each group of possible scores are:

3, 7, 11, 16, 12, 21, 15, 20, 25, 30

Examples of rudimentary addition:

1. 3+7+30 =40

2. 7+11+30=48

3. 11 + 16 + 30= 57

4. 16+12+30 =58

5. 12+21+30=63 etc

Again, using a rudimentary count, we can prove that no three categories all summed up, will add up to exactly 50 points.

Answer:  Choice D

Fold the paper so that A is on top of B

Or vice versa

===========================================

Explanation:

M is the midpoint of segment AB.

This means that segments AM and MB are the same length, by definition of what it means to be a midpoint.

We have symmetry going on about point M. When we fold the paper, we're introducing symmetry. Point M will be on the folding line, and the folding line is the perpendicular bisector of AB.

Explanation:

Simplify the left hand side to get

[tex]\frac{2}{A}+\frac{1}{B} = \frac{13}{15}\\\\\frac{2B}{AB}+\frac{A}{AB} = \frac{13}{15}\\\\\frac{2B+A}{AB} = \frac{13}{15}\\\\[/tex]

Step-by-step explanation:

Talia needs to factor out a negative from one of the groups so the binomials will be the same.

Given

Talia grouped the terms and factored out the GCF of the groups of the polynomial 15x^2 – 3x – 20x + 4.

The GCF (Greatest Common Factor) of two or more numbers is the greatest number among all the common factors of the given numbers.

To find the GCF of the two terms, the continuous division must be done.

Talia needs to factor out a negative from one of the groups so the binomials will be the same.

She should do as follows:

[tex]\rm (15x^2- 3x) + (-20x + 4)\\\\3x(5x-– 1) + 4(-5x + 1)\\\\3x(5x - 1) - 4(5x - 1)[/tex]

Hence, Talia needs to factor out a negative from one of the groups so the binomials will be the same.

Answer:

Aubrey ran 3 1/3 miles further than what she walked.

Step-by-step explanation:

This would be your basic subtraction problem. So, 13 1/6 - 9 5/6.

Since you can't subtract 5/6 from 1/6, let's borrow from 13. Now, instead of 13, it would be 12. Adding the whole (1) or 6/6 to the 1/6, you'll get 7/6. Now you can subtract. 7/6 - 5/6 = 2/6. Moving on, 12 - 9 = 3.

Therefore, your answer is 3 2/6. In simplified terms, it would be 3 1/3.

======================================================

Explanation:

The x coordinate of the preimage point Q is x = 6.

The x coordinate of the image point Q' is x = 21.

The ratio of image over preimage is 21/6 = (3*7)/(3*2) = 7/2

You'll get this same value if you do the same steps with the y coordinates.

Therefore, the scale factor is 7/2 and the dilation rule is [tex](x,y) \to \left(\frac{7}{2}x, \frac{7}{2}y\right)[/tex]

Note: 7/2 = 3.5

Step-by-step explanation:

The angles that are marked are called "vertical angles" (I think of a pair of scissors) The two angles are equal to each other. (They get bigger or smaller together, like a pair of scissors)

So, set them equal to each other and solve.

3x + 50 = 6x - 10

SUBTRACT 3x from both sides.

50 = 3x - 10

ADD 10 to both sides.

60 = 3x

DIVIDE both sides by 3.

Answer:

6,6

There are 8 spaces in bettween  point a and b so 8/2 = 4 so 4 up from point a is 6,6

Step-by-step explanation:

Answer:

1. CD = 6√3

2. AD = 18

3. ΔABC is an enlargement of ΔCBD by a scale factor of 2

4. 4 : 1

Step-by-step explanation:

The altitude of a triangle is the perpendicular line segment drawn from the vertex of the triangle to the side opposite to it.  

Therefore, line CD is an altitude

If an altitude is drawn from the right angle of any right triangle, then the two triangles formed are similar to the original triangle and all three triangles are similar to each other.

If two objects are similar, their corresponding angles are congruent (the same) and their sides are proportional in length.

Therefore, if m∠B = 60°  then  m∠C of ΔADC = 60°

If m∠A = 30° then m∠C of ΔCBD = 30°

This means that all triangles are 30-60-90 triangles.  30-60-90 triangles are special right triangles as the angles of these triangles are in a unique ratio of 1:2:3.  This means that the lengths of the sides is always in the ratio of 1 : √3 : 2  ⇒  y : y√3 : 2y

1.  Using the 30-60-90 triangle formula for sides:

    For ΔCBD:  CD = y√3,  CB = 2y,  DB = y

    We are told CB = 12  ⇒  2y = 12  ⇒  y = 6

    Therefore, CD = y√3 = 6√3

2.  Using the 30-60-90 triangle formula for sides:

    For ΔADC:  CD = y,  AC = 2y,  AD = y√3

    We know that CD = 6√3  ⇒  y = 6√3

    Therefore, AD = y√3 = 6√3√3 = 18

3.  Using the 30-60-90 triangle formula for sides:

    For ΔABC:  CB = y,  AB = 2y,  AC = y√3

    We know that CB = 12  ⇒  y = 12

    Therefore, AB = 24  and  AC = 12√3

Therefore, ratio of ΔABC : ΔCBD using the lengths of their hypotenuse:

24 : 12  ⇒  2 : 1

Therefore, triangle ΔABC is an enlargement of triangle ΔCBD by a scale factor of 2

4.  Area of a triangle = 1/2 x base x height

   ⇒  Area ΔABC = 1/2 x BC x AC = 1/2 x 12 x 12√3 = 72√3

   ⇒  Area ΔCBD = 1/2 x DB x CD = 1/2 x 6 x 6√3 = 18√3

    Therefore,  Area ΔABC : Area ΔCBD  ⇒  72√3 : 18√3  ⇒  4 : 1

Plantearemos una ecuación cuadratica, y resolviendola veremos que Federico tiene 21 años.

Lo primero que debemos hacer es definir la variable que vamos a usar, en este caso usare:

F = edad de Federico.

Dentro de 11 años, la edad de Federico será:

F + 11

Hace 13 años, la edad de Federico era:

F - 13

Reemplazando eso en lo que el problema plantea, tenemos:

(F + 11) = 0.5*(F - 13)^2

Ahora podemos resolver esto para F.

F + 11  = 0.5*(F^2 - 26*F +169)

F + 11 = 0.5*F^2 - 13*F + 84.5

Movemos todo al mismo lado:

F + 11 - 0.5*F^2 + 13*F - 84.5 = 0

-0.5*F^2 + 14*F - 73.5 = 0

Ahora tenemos una ecuación cuadratica, la cual resolvemos usando la formula de Bhaskara:

[tex]F = \frac{-14 \pm \sqrt{(14)^2 - 4*(-0.5)*(-73.5)} }{2*(-0.5)} =\frac{-14 \pm 7}{-1}[/tex]

Esto nos da dos valores:

El problema con el primer valor, es que es inconsistente con el enunciado, ya que en ese caso, Federico hace 13 años tendría una edad negativa. Así que descartamos la primer solución y nos quedamos con la segunda.

F = 21

Federico tiene 21 años.

Answer:

Step-by-step explanation:

5a - 4b - c  = 8

4a + 2b - c = 2

3a + 4b + 3c = -16

by adding equation 1 and 2 we get

8a + 2c = -8

4a + c = -4

c = -4 - 4a

now substitute c in the 2nd equation

4a + 2b +4 + 4a = 2

8a + 2b = -2

4a + b = -1

b = -1 - 4a

we have b and c in terms of a, now let's find a

5a - 4(-4-4a) - (-1 - 4a) = 8

5a + 16 + 16a + 1 + 4a =8

25a = -9

a = -9/25

b = -1 - 4(-9/25)

b= -1+36/25=11/25

c=-4 -4a = -4 +36/25=-53/25

Logan's swimming average is 2.25 kilometers per hour.

Mila's swimming average swimming speed is 34.44 m/min.

The distance swam by Logan = 750 m

The distance swam by Mila =  of Logan's distance =   × 750 = 2 × 250 = 500.

Answer:

y=16.

Step-by-step explanation:

Using substitution requires us to substitute a value in place of another value. Luckily we are given the value of x and can use it in the second equation.

First, we substitute 4 for x.

y=2(4)+8

And then we simply solve.

y=2(4)+8

y=8+8

y=16
