Ayudaaaaa porfavor Convertir las unidades de medida 8 000 m = _______ km 4 000 g = _______ kg 3 000 m = ________ km 7 m = ______
jek_recluse [69]

Answer:

a) x = 8\,km, b) x = 4\,kg, c) x = 3\,km, d) x = 700\,cm, e) x = 3\,cm, f) x = 100\,mm, g) x = 7\,mm, h) x = 10000\,mL, i) x = 8\,m, j) x = 6000\,g

Step-by-step explanation:

a) 1 kilómetro equivale a 1000 metros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

x = 8000\,m \times \frac{1\,km}{1000\,m}

x = 8\,km

b) 1 kilogramo equivale a 1000 gramos, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

x = 4000\,g \times \frac{1\,kg}{1000\,g}

x = 4\,kg

c) 1 kilómetro equivale a 1000 metros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

x = 3000\,m \times \frac{1\,km}{1000\,m}

x = 3\,km

d) 1 metro equivale a 100 centímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

x = 7\,m \times \frac{100\,cm}{1\,m}

x = 700\,cm

e) 1 centímetro equivale a 10 milímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

x = 30\,mm \times \frac{1\,cm}{10\,mm}

x = 3\,cm

f) 1 centímetro equivale a 10 milímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

x = 10\,cm \times \frac{10\,mm}{1\,cm}

x = 100\,mm

g) 1 centímetro equivale a 10 milímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

x = 70\,mm\times \frac{1\,cm}{10\,mm}

x = 7\,mm

h) 1 litro equivale a 1000 mililitros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

x = 10\,L\times \frac{1000\,mL}{1\,L}

x = 10000\,mL

i) 1 metro equivale a 100 centímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

x = 800\,cm \times \frac{1\,m}{100\,cm}

x = 8\,m

j) 1 kilogramo equivale a 1000 gramos, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

x = 6\,kg\times \frac{1000\,g}{1\,kg}

x = 6000\,g

WILL MARK BRAINIEST!!1 PLZ HELP!25 points!!! The coordinate grid shows points A through K. What point is a solution to the syste
marishachu [46]

Answer:

A, C, D and K

Step-by-step explanation:

Inequalities:

y ≤ −2x + 10  and  y >1/2x-2

<u>Finding zeros for the first inequality:</u>

  • x=0 ⇒ y= 10, point (0, 10)
  • y=0 ⇒ x= 5, point (5, 0)
  • Locating these 2 points and connecting to get the first line.

Space to the left of this line (as y≤ ) is the solution for this inequality, any points on this line are inclusive.

<u>Finding zeros for the second inequality:</u>

  • x=0 ⇒ y= -2, point (0, -2)
  • y= 0 ⇒ x= 4, point (4, 0)
  • Locating these points and connecting to get the second line.

Space above this line (as y > sign) is the solution for this inequality, any points on this line are not inclusive.

Now we have the space of intersection of the above inequalities.

So the points in same section are the solution.

They are:

  • Points A, C, D and K
