El boleto de entrada al palacio de la ciencias cuesta 5 pesos por niño y 10 pesos por adulto. al final del día 50 personas visitaron el palacio y el ingreso total de las entradas fue de 350 pesos. ¿cuántos adultos visitaron el palacio?

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

the radius is 2 times the diameter.

step-by-step explanation:

93-8=85

855=17

17*4=68
