Cuando María afirma que si unen sus dos cuartos de cartulina obtendrán el medio pliego que necesitan, esto es:

Step-by-step explanation:

Para entender mejor el ejercicio vamos a utilizar números cada vez que se habla de cantidades de cartulina, por lo tanto, María y Juan tienen 1/4 de cartulina cada uno, es decir, 1/4 * 2, y necesitan 1/2 pliego para poder realizar su tarea, por lo tanto, con la afirmación de María sobre unir los dos cuartos de cartulina, en caso de que sea verdadero, ocurrirá que la suma de los dos cuartos dará el medio pliego, como se muestra a continuación:

Procedemos a simplificar el fraccionario obtenido, sacando mitad tanto en el numerador como en el denominador:

Como puedes ver al final, la cantidad de cartulina de ambos, al ser sumada, da como resultado el 1/2 (medio) pliego que necesitan para su tarea de sociales, por lo cual la afirmación de María es correcta.

Answer:

6.9 cm

Step-by-step explanation:

hyp² = adj² + opp²

Answer:

x = 6.93 cm

Step-by-step explanation:

Pythagorean theorem: c = [tex]\sqrt{a^2 + b^2}[/tex]

C is the hypothenuse, the longest side of a right angled triangle.

Here c = 8, 4 =a, b = x.

[tex]8 = \sqrt{(4)^2+(b)^2}[/tex]

[tex]64 = (4)^2 + (b)^2[/tex]

[tex]64 = 16 + (b)^2[/tex]

[tex]b^2 = 48\\b = \sqrt{48} = 6.93 cm[/tex]

Answer:

62 sq units

Step-by-step explanation:

Area of top and bottom rectangles =

2(5x3) = 15 x 2 = 30

Area of front facing and back facing rectangle =

2(2x5) = 2 x 10 = 20

Area of side facing rectangles =

2(2x3) = 2 x 6 = 12

Total surface area = 30+20+12 = 62

Answer:

x = 36º

Step-by-step explanation:

The sum of the angles in a triangle is 180º

x + 2x + 72 = 180

Combine like terms

3x + 72 = 180

Subtract 72 from both sides

3x = 108

Divide both sides by 3

x = 36º

Answer:

4ft

Step-by-step explanation:

to get the area of a square you multiply the sides together so you just find the square root of the area

Answer:

4 feet would be the legth of the squares side

Step-by-step explanation:

t16 is the squares area and the area of a square is length X width, since all the sides of a square are equal, we can just take the square root of  16 which is 4 feet.

Answer: 30.2

Explanation:

The mean is calculated by taking the sum of the values and dividing by the count.

For instance, for the 6 women, with the mean being 31, we can see that the ages summed to 186:

186

6

=

31

And we can do the same for the men:

116

4

=

29

And now we can combine the sum and count of the men and women to find the mean for the office:

186

+

116

10

=

302

10

=

30.2

Step-by-step explanation:

9514 1404 393

Answer:

  30

Step-by-step explanation:

The total of the ages of the 11 women is 11·31 = 341. The total of the ages of the 6 men is 6·29 = 174. Then the total of the ages of all 17 people in the office is ...

  341 + 174 = 515

and their average age is ...

  515/17 ≈ 30.294 ≈ 30

The mean age of the people in the office, to the nearest year, is 30.

_____

The mean is the total divided by the number of contributors. Then the total is the mean times the number of contributors.

Answer:

This is the edmentum simple answer

Step-by-step explanation:

Answer:

(-2, -1).

Step-by-step explanation:

y = x² + 4x + 3

Completing the square:

y = (x + 4/2)^2 - (4/2)^2 + 3

y = (x + 2)^2 - 4 + 3

y = (x + 2)^2 - 1.

This is vertex form and the coordinates of the vertex are (-2, -1).

Step-by-step explanation:

Answer:

D.0

Step-by-step explanation:

If you graph the equation you can see that it doesn't cross the x-axis. It doesn't go lower than y=1. If you don't have a graphing calculator use Desmos. Also the +1 at the end of the equation tells you that it won't go lower than y=1.

Answer:

Never your answer is 0

Step-by-step explanation:

The equation creates what's called a parabola the line curves up the 1 represents the y axis so the line curves up from the y axis point 1 never touching the x axis

Answer:

2.65secs

Step-by-step explanation:

Give:

The function h(t)=−16t(t−7) models

the object will hit the ground at h= 0

h(t)=−16t(t−7)

0= -16t(t−7)

0= -16t^2 + 112

16t^2 = 112

t^2 = 7

t= √7

t=2.65secs

Hence, the object object hit the ground at 2.65secs

[tex]\sqrt{5}[/tex] + 8

Step-by-step explanation:

To rationalise the denominator, multiply the numerator and denominator by the conjugate of the denominator.

The conjugate of [tex]\sqrt{5}[/tex] - 8 is [tex]\sqrt{5}[/tex] + 8 , then

[tex]\frac{\sqrt{2}(\sqrt{5}+8) }{(\sqrt{5}-8)(\sqrt{5}+8) }[/tex]
