Answer:
4 units
Step-by-step explanation:
according to question:
perimeter of square = 16 units
4a = 16
where a is the side length
a = 16/4
= 4 units
Answer:
To figure out the total measure of the angles for a 27-gon, there is a formula.
n - 2 x 180* (n is the number of sides, which would be 27)
27 - 2 = 25
25 x 180* = 4500*
The total measure of the angles of a 27-gon is: 4500*
Step-by-step explanation:

Answer: = 240 mph.
Step-by-step explanation:
Let x = speed of the plane.
t= time taken
As per given, we have
[Time = distance / speed]
From (i) and (ii), we get
![\dfrac{450}{x+30}=\dfrac{350}{x-30}\\\\\Rightarrow\ 450(x-30)=350(x+30)\\\\\Rightarrow\ 450x-13500=350x+10500\\\\\Rightarrow\ 450x-350x=10500+13500\\\\\Rightarrow\ 100x=24000\\\\\Rightarrow\ x=240](https://tex.z-dn.net/?f=%5Cdfrac%7B450%7D%7Bx%2B30%7D%3D%5Cdfrac%7B350%7D%7Bx-30%7D%5C%5C%5C%5C%5CRightarrow%5C%20450%28x-30%29%3D350%28x%2B30%29%5C%5C%5C%5C%5CRightarrow%5C%20450x-13500%3D350x%2B10500%5C%5C%5C%5C%5CRightarrow%5C%20450x-350x%3D10500%2B13500%5C%5C%5C%5C%5CRightarrow%5C%20100x%3D24000%5C%5C%5C%5C%5CRightarrow%5C%20x%3D240)
Hence, the speed of the plane = 240 mph.
