Answer:
0.6625
Step-by-step explanation:
To find the surface area, calculate the area of each shape and add it together, A pyramid has 1 square and 4 triangles in its net,
Area of square is A=s*s=0.25*0.25=0.0625.
Area of a triangle is A= 1/2 b*h = 1/2 (0.25)(1.2) = 0.15.
There are four equal triangles so together there area is 4*0.15 = 0.60.
Add the square to it and you have the surface area of the pyramid.
0.0625 + 0.60 = 0.6625
I think you do 550 x .16(16%)=88 and each CD sells for 44 so 88/44
Answer= He needs to sell 2 CD's
<span>the line over the 28 means the 28 repeats forever.
1.282828.... and so on
let x be the rational number 1.28...
we can use this trick:
100*1.282828....= 128.282828...
(the decimal 28 part repeats)
100x = 128.28...
next:
100x - x = 128.282828... - 1.282828...
the .282828... part will be subtracted away
99x = 127
divide both sides by 99 to get
x= 127/99</span>
