Answer:
Step-by-step explanation:
1) point slope form is:
y-y1=m(x-x1)
y1=8
x1=4
m=(slope)
to find m: y2-y1/x2-x1
hence
-2-8/2-4=-10/-2=5
m=5:
y-8=5(x+4)

Answer:
14.1% to 1 decimal place.
Step-by-step explanation:
The amount left over = 320 - 275 = 45.
As a percentage of the original 320 this is 45 * 100 / 320
= 14.0625 %.
We know that total surface area is the area of of the base + area of all the walls + area of the top
here we are working with a pyramid whose base is a square but the wall are four triangles
as triangles are connected on the top , there would be no top area ( as the top would be a point ( where all four triangles are being join )
so total area is = area of base + area of four walls ( triangles here )
