False, because it would no longer be 18 alone because of the disturbutive property.
62% because 200 silver coins out of 323 (total of all coins) is .619..., resulting in 62%
Answer:
The answer is below
Step-by-step explanation:
a) Let negative means the turtle position when descending and positive for going up. Therefore since the turtle was 850 meters below see level, it was at -850. It then moves 165 meters up, hence its new position is -685 meters (-850 + 165). Lastly it moves down 165 meters, hence its new position is -850 meters (-685 - 165)
b) The change in position is the sum of the movements = +165 - 165 = 0 meters.
You have the answer into the images.
Ok, to solve this, once again you need to fold this map back up into a 3d shape ( in your head).
What you should see is that the little overhanging sides that had no measurement, now have a measurement. They measure up to be the same as the 3m. sides.
so to find the area of all the rectangles, you need to multiply the base times height. (b)h
I will start from the left of your pic. and work my way to the right...not including the little overhanging ones.
The first one should measure out to be 3(15) =45
The second to be 6(15) =90
The third to be 3(15) =45
The fourth to be 6(15) =90 :)
So you have these, but now you need to get the little over hangers I call them...lol.
The width is 6, same as the rectangle they are attached to. And the picture in your mind should tell you that the height is 3, the same as the width of the skinny rectangles that they attach to in your mind.
Soooo now they measure out to be 3(6) =18. and you just multiply this by two because they are the same area, right? So that would be 36.
ok. Now add all of the areas of the surfaces 45+90+45+90+36 to get a total surface area of.... *drummel please* 306m^2
this means 306m. to the power of 2 if you didn't know.
well, I hope you understand better and I hope I helped! ;)
