Si colocan en 16 pisos, 16 ladrillos. ¿Cuántos ladrillos pusieron en total?. (expresarlo en forma de potencia)
inn [45]

Answer:

Númer total de ladrillos= 256

Step-by-step explanation:

<u>Dada la siguiente información:</u>

Total de pisos= 16

Total de ladrillos por piso= 16

<u>Para calcular cantidad de ladrillos en total, tenemos que usar la siguiente formula:</u>

Número total de ladrillos= total de ladrillos^2

Número total de ladrillos= 16^2

Númer total de ladrillos= 256

En este caso lo hace al cuadrado por que la cantidad de pisos y ladrillos por piso es la misma. Sino, es mejor expresarlo como una multiplicación.

Whats the slope and the equation
vichka [17]
You can find the slope of a line by having two points. In this case we have 5 different point so we pick two.

so for the first one I will pick (2,17) and (7,37)

we use (y2-y1) / (x2-x1)  this is rise over run

plug and chug to get slope.
(37-17)/(7-2)= 4 

now use point slope using one of the point that we used to find the slope
y−b=m(x−a<span>) or y-y1 = m (x-x1)

plug and chug again
m=4 ............ point (2,17)

y- 17 = 4 (x- 2)
y= 4x +10 

hope this helps
