Answer:

Step-by-step explanation:

Let $x$ be the height of the model. We have $\frac{180}{x} = \frac{3.5}{1.5}$ . Hence, we have $x=\frac{180}{3.5}\cdot 1.5 \approx 77.1$ .

Dos familias asisten a un sitio de comidas rápidas de la ciudad, una de ellas pide 4 perros calientes y 3 hamburguesas y pagan 4

natta225 [31]

Answer:

Cada perro caliente cuesta 5,500 pesos y cada hamburguesa cuesta 7,000 pesos.

Step-by-step explanation:

Sea x el precio de los perros calientes y y el precio de las hamburguesas.

Escribiendo los datos de la primera familia en forma de ecuación tenemos:

$4x+3y=43,000$ (4 perros calientes y 3 hamburguesas cuestan 43,000 pesos)

Escribiendo los datos de la segunda familia:

$5x+y=34500$ (5 perros calientes y 1 hamburguesa cuestan 34,500 pesos)

Vamos a resolver este sistema de ecuaciones por el método de suma y resta:

$4x+3y=43,000\\5x+y= 34,500$

Multiplicando la segunda ecuación por -3 y sumando ambas tenemos:

$4x+3y=43,000\\-15x-3y= -103,500\\\\-11x=-60,500\\x=-60,500/-11\\x= 5,500$

Por lo tanto, un perro caliente cuesta 5,500 pesos.

Ahora sustituimos este valor en nuestra segunda ecuación para encontrar el precio de las hamburguesas:

$5x+y=34500\\5(5,500)+y=34,500\\27,500 +y=34,500\\y=34,500-27,500\\y=7,000$

Por lo tanto, las hamburguesas cuestan 7,000 pesos cada una

I NEED HELP BRAINLIEST+POINTS!!!!!!!!

Marizza181 [45]

Answer:

Angles 1 and 2 are Complementary angles

Step-by-step explanation:

There is probably some vocabulary is your lesson, but from my knowledge, these angles would be complementary because they add up to 90 degrees total. Complementary angles are either of two angles that add up to 90 degrees, since it is shown that the other three angles besides these two are 90 degrees (thats what the square signifies), then these two angles have to add up to 90 degrees as well which will make them complementary.
