Answer:
EACH TIE COSTS 7.43
Step-by-step explanation:
If 13.35x13=173.55 then that means the ties total is 189.46 now devide that by 22 it equals 13.35
#9)
|360 - 380| = |-20| = 20
answer
Distance between 360 and 380 on the number line is 20
If you think about it, an octagon is made up of 8 triangles. So you first find the area of one triangle then multiply it by 8 for the total area:
A=1/2bh
A=1/2(9.9)(12)
A=59.4
59.4 x 8= 475.2
Therefore the total area for the octagon should be 475.2 units^2
