Un alumno multiplica un número por 32 en lugar de multiplicarlo por 23, obteniendo un producto mayor en 54 al producto original.
romanna [79]

Answer:

La suma de cifras del producto original es igual a 12.

Step-by-step explanation:

De acuerdo a la información proporcionada, si multiplicas un número "x" por 32 su resultado sería igual al producto original "y" más 54 dado que dice que se obtiene un producto mayor en 54 al producto original, lo que se puede expresar de la siguiente forma:

32x=y+54

Además, se puede inferir a partir del enunciado que si el número x se hubiera multiplicado por 23 el resultado habría sido el producto original que lo denominamos como "y", por lo que puedes decir que:

y=23x

Ahora puedes reemplazar y=23x en 32x=y+54 y despejar x:

32x=23x+54

32x-23x=54

9x=54

x=54/9

x=6

Finalmente, puedes reemplazar el valor de x en y=23x:

y=23x

y=23*6

y=138

Suma de cifras: 1+3+8 = 12

De acuerdo a esto, la respuesta es que la suma de cifras es igual a 12.

9. What is the tan(90-x)?
Aleonysh [2.5K]

\\ \sf\longmapsto tanx=\dfrac{Perpendicular}{Base}

\\ \sf\longmapsto tanx=\dfrac{4}{3}

\\ \sf\longmapsto x=tan^{-1}(4/3)

\\ \sf\longmapsto x=53°

\\ \sf\longmapsto tan(90-x)

\\ \sf\longmapsto cotx

\\ \sf\longmapsto cot53

\\ \sf\longmapsto \dfrac{3}{4}

\\ \sf\longmapsto 0.75
