1) La base de un pozo cilíndrico de cemento tiene una superficie de 45 metros cuadrados. El agua potable que contiene alcanza los 2,5 metros
de altura, y para vaciarlo se utiliza una motobomba que extrae 8 hl
(hectolitros) por minuto.
a) ¿Cuántas horas tardará la bomba en vaciarlo?
b) ¿Cuántos 3
le habrá faltado al pozo para que se llene
completamente si su altura máxima es de 3,4 metros?

no not all of them.

step-by-step explanation:

some of them have a square base.

20

step-by-step explanation:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
