The sum of the measures of all the interior angles of the pentagon is 540°. Option B
<h3>How to determine the sum</h3>
Note that
Sum of Interior Angles in a Pentagon = 540°
A pentagon is formed from three triangles, so the sum of angles in a pentagon = 3 × 180° = 540°
If one of the interior angles = 108°, then the other two angles = 2 * 108° = 216°
The sum of the interior angles = 108° + 216° = 540°
Therefore, the sum of the measures of all the interior angles of the pentagon is 540°

Answer:
230 mph
Step-by-step explanation:
Let speed of plane in still air be x. Therefore, when against the wind speed, the resultant speed is x-40 mph. Equally, when with the wind speed, the resultant speed is x+40 mph. The time is the same hence we can express these as
By cross multiplication
675(x-40)=475(x+40)
675x-27000=475x+19000
200x=46000
X=46000/200=230 mph
- <em>combined mass in scientific notation can be written as</em> 97.2× kg
- Scientific notation can be regarded as a way of writing very large as well as very small numbers.
Mars of mass= (6.42x kg )
Mercury= (3.3x kilograms)
Then we add together
(6.42x )+ (3.3x) kilograms.
= 9.45 × kilograms
Therefore, combined mass in scientific notation can be written as 97.2× kg

Both the equation show a graph of a parabola. The equation y=-x^2+1 is a parabola opening downward since the x variable has a negative sign. While the equation y=x^2 is also a parabola opening upward since x^2 is positive. Both parabola have axis of symmetry on the y-axis. Vertex for the first parabola is on (0,1) while the second parabola is at the origin.
