11
A diagonal connects a vertex to another vertex without being a side of the polygon. There are 14 vertices in a 14-gon. This leaves 13 vertices left to connect to (since we cannot connect the vertex to itself). However, two of these vertices will form the sides of the 14-gon. This leaves us with 11 possible diagonals we can draw.
Answer:
47.13
Step-by-step explanation:
15inch is the diameter so do
3.142 x 15 = 47.13
M^3 is the square root of m6
To solve the problem we will use this equation where,
d will be distance.
<span>x is the speed of the plane without tailwind. </span>
<span>y is the speed of the wind affecting the plane.</span>
Going to Philadelphia the speed of the plane affected by wind will be x-y=220 miles/hr
Coming back with a tailwind, the speed of the plane will be x+y= 280 miles/hr.
since time = distance / speed, t1 =d/220 and t2 = d/280
and since the total time traveled is 6.5hrs
d/220 + d/ 280 = 6.5hrs
d = 800.8 miles x 2 (back and forth trip) the answer is 1601.6 miles
Answer:
2x+2y
Step-by-step explanation:
Use the distributive property:
2(x+y)=2x+2y
Have a nice day :-)
