Please help find the perimeter
Usimov [2.4K]

Answer:

Perimeter of the given figure = 28 units

Step-by-step explanation:

Perimeter of the given figure = Length of AB + Length of BC + Length of CD + Length of DE + Length of EF + Length of FG + Length of GH + Length of AH

Length of AB = 4.5 units

Length of BC = 2 units

Length of CD = 2 units

Length of DE = 4 units

Length of EF = 5.5 units

Length of FG = 1.5 units

Length of HG = 1 units

Length of AH = 7.5 units

Perimeter of ABCDEFGH = 4.5 + 2 + 2 + 4 + 5.5 + 1.5 + 1 + 7.5

                                          = 28 units

padilas [110]

Answer:

Respondió mal 64 preguntas.

Step-by-step explanation:

De acuerdo a la información proporcionada puedes plantear las siguientes ecuaciones:

x+y=120 (1)

2x-0,5y=80 (2)

x es el número de preguntas correctas

y es el numero de preguntas incorrectas

Primero debes despejar "x" en (1):

x=120-y (3)

Después, debes reemplazar (3) en (2):

2(120-y)-0,5y=80

240-2y-0,5y=80

240-80=2,5y

160=2,5y

y=160/2,5

y=64

Ahora puedes reemplazar el valor de "y" en (3) para encontrar el valor de "x":

x=120-y

x=120-64

x=56

De acuerdo a esto, la respuesta es que el postulante respondió mal 64 preguntas.
