Usando proporciones, hay que se debe hornear un pavo de 7 y 1/2 libras en 4.5 horas.

<h3>Lo que es una proporción?</h3>
  • Una proporción es una fracción de la cantidad total, y las medidas se relacionan usando una regla de tres.
  • En este problema, para cada libra y quarto de peso, o sea 1\frac{1}{4} = 1 + \frac{1}{4} = \frac{5}{4} de libras, el tiempo en horas es de \frac{3}{4}. Qual el tiempo para un peso en libras de 7\frac{1}{2} = 7 + \frac{1}{2} = \frac{15}{2}?

La <em>regla de tres</em> es:

Peso(libras) - Tiempo(horas)

\frac{5}{4} - \frac{3}{4}

\frac{15}{2} - x

Aplicando multiplicación cruzada:

\frac{5}{4}x = \frac{45}{8}

x = \frac{45 \times 4}{5 \times 8}

x = \frac{9}{2}

x = 4.5

Se debe hornear un pavo de 7 y 1/2 libras en 4.5 horas.

babunello [35]

Answer: The expression representing the amount of money spent is 5x+60 by Emily.

Step-by-step explanation:

Since we have given that

Let the cost price of per pair of sandals be 's'

Let the cost price of per pair of  boots be 's+30'.

Number of pairs of boots = 2

Number of pairs of sandals = 3

Total cost would be

2(s+30)+3s\\\\=2s+60+3s\\\\=5s+60

Hence, the expression representing the amount of money spent is 5x+60 by Emily.
