From one vertex of an octagon you can draw 5 diagonals.
There are 8 vertices in an octagon, and we are choosing one as our starting vertex. There are then 7 vertices left to draw a line to, but 2 of the vertices are already connected to our main vertex (because they are connected along the side of the octagon). That leaves 5 vertices to draw a diagonal to from our original vertex.
Answer:
35,45,55 is not a triangle
Step-by-step explanation:
The three angles of a triangle add to 180
30+60+90 = 180
true
45+55+80 = 180
true
30+45+105 =180
true
35+45+55 =180
135 does not =180
false
Answer:
Mr. Chang will have 15714.90 dollars.
Step-by-step explanation:
p = 650
r = 
Number of periods or n = 
Future value formula is : ![p[\frac{(1+r)^{n}-1}{r} ]](https://tex.z-dn.net/?f=p%5B%5Cfrac%7B%281%2Br%29%5E%7Bn%7D-1%7D%7Br%7D%20%5D)
Putting the values in formula we get;
![650[\frac{(1+0.0195)^{20}-1}{0.0195} ]](https://tex.z-dn.net/?f=650%5B%5Cfrac%7B%281%2B0.0195%29%5E%7B20%7D-1%7D%7B0.0195%7D%20%5D)
= $15714.90
Hence, Mr. Chang will have 15714.90 dollars.
Answer:
The fraction 58/60 is equal to 29/30 when reduced to lowest terms. To find equivalent fractions, just multiply the numerator and denominator of that reduced fraction (29/30) by any interger number, ie, multiply by 2, 3, 10, 30... 58/60 is equivalent to 29/30 because 29 x 2 = 58 and 30 x 2 = 60
Step-by-step explanation:
Dont know if this helps but i hope it does!
The formula for finding circumference is Pi multiplied by diameter.
3.14 x 25ft = 78.5 feet
This would round up to 79 feet in circumference.
