I NEED HELPPP<br><br> Whats the length of LN?
andre [41]

Answer:

LN = 66 cm

Step-by-step explanation:

The 3 parallel lines divide the 2 sides they intersect in proportion, that is

\frac{DE}{EF} = \frac{LM}{MN} , substitute values

\frac{7}{15} = \frac{LM}{45} ( cross- multiply )

15LM = 315 ( divide both sides by 15 )

LM = 21

Hence

LN = LM + MN =  21 + 45 = 66 cm

Choose the linear inequality that describes the graph. The gray area represents the shaded region.
jek_recluse [69]

Answer:

2x + 3y ≥ 5

Step-by-step explanation:

See the graph attached.

The bold straight line passes through the points (1,1) and (4,-1).

Therefore, the equation of the straight line will be  

\frac{y + 1}{- 1 - 1} = \frac{x - 4}{4 - 1}

⇒ 3(y + 1) = - 2(x - 4)

⇒ 3y + 3 = - 2x + 8

⇒ 2x + 3y = 5 ............. (1)

Now, the shaded region i.e. the solution to the inequality does not include the origin(0,0).

So, putting x = 0 and y = 0 in the equation (1) we get, 0 < 5

Therefore, the inequality equation is 2x + 3y ≥ 5 (Answer)

The amount of workers varies inversely with the time, in days, to complete a project. Five workers can complete a certain projec
Feliz [49]

9514 1404 393

Answer:

  8

Step-by-step explanation:

The number of days has gone down by a factor of 15/24. The number of workers is inversely proportional, so must increase by a factor of 24/15 = 8/5.

  (5 workers) × (8/5) = 8 workers

8 workers are needed to complete the project in 15 days.

El jefe de ventas comenta con tu padre que los 9.000 vehículos del mes pasado suponen unos buenos resultados, pero que este mes
Alja [10]

Answer:

900

Step-by-step explanation:

10% de 9000 es 900

Trabajando el 10% de 9000

Escribe 10% como 10100

Dado que, encontrar la fracción de un número es lo mismo que multiplicar la fracción por el número, tenemos

10100 de 9000 = 10100 × 9000

Por tanto, la respuesta es 900

Si está utilizando una calculadora, simplemente ingrese 10 ÷ 100 × 9000, lo que le dará 900 como respuesta.
