1. The problem says that the stone covers 29.26 square inches. So, the first thing you must do, is to convert 29.26 square inches (in²) to square feet (ft²):
1 in²=0.00694 ft², then:
29.26x0.00694= 0.20 ft²
2. The triangular area has the following surface:
A=bxh/2
A=(6 ft)(8 ft)/2
A=24.0 ft²
3. <span> Finally, the number of stones (N) that cover the triangular area is:
</span>
N= 24.0 ft²/0.20 ft²
N=120 stones
Answer: <span>Kiana should buy 120 stones to cover the triangular area in her backyard.</span>
The area depends on whether the 8dm path runs top to bottom or left to right
the followin solution will be for left to right
we need to draw a picture (see first attachment)
to simplify it, we can push the paths to the side (see second attachment)
now we can easily see that the usable area is the part not used by the paths
the width is 20-0.7=19.3
the height is 30-0.8=29.2
area=19.3*29.2=563.56 square meters
if it was frmo top to bottom
20-0.8=19.2
30-0.7=29.3
19.2*29.3=562.56 square meters
if the path is like in the attachments, then the usable area is 563.56 square meters
if the 7dm path and the 8dm path are switched, then the usable area is 562.56 square meters
C.) Is 4 to the 8 power.
D.) Is 6 to the 9 power.
F.) Is 3 to the 9 power.
G.) Is 173 to the 11 power over 1000 to the 11 power.
H.) Is 7569 over 10000.
I.) Is 25 over 4.
Pythagorean stack i believe its 23 on the side
