The surface area of what?
Answer:
20%
Step-by-step explanation:
1,9,11,19,21,29,31,39,41,49,51,59,61,69 this is that series of numbers .These are total 14 numbers out of 70 so 14/70×100 gives us 20 % occurrence of 1 or 9 at unit place.
The slope of the line is 4/11. to find this use, m=y2-y1/x2-x1 :)
Answer:
The possible length is greater than 29 meters.
Step-by-step explanation:
If the length is x then the width is x - 2 m.
So the perimeter is 2x + 2(x - 2) = 4x - 4 m.
4x - 4 > 112
4x > 116
x > 29 m.
A line is 180 degrees so write x+(4x-20)=180
