Answer:
The distance flown
Step-by-step explanation:
The distance flown is dependent on the speed of the plane
Answer:
Speed of sound is 340 meter per second.
Step-by-step explanation:
Let the speed of sound = x meter per second.
It is given that,
The new mode of travel has the speed 170 meter per second, which is 50% less than the speed of sound.
So, we get,
x - 50%x = 170
i.e. x - 0.5x = 170
i.e. 0.5x = 170
i.e. x = 340 meter per second
Hence, the speed of sound is 340 meter per second.
Area of circle = Pi x r*2
If diameter is 18, radius is 9.
Area = pi (3.14) x r*2 (9*2 = 81) .. 3.14 x 81 = 254.34 sq cen = total area of circle.
A circle is 360 degrees, the shaded area is 270 degrees. the shaded area is 3/4 (270/360) of the area of the circle.
254.34 x 3/4 = 190.755 sq cen
Hope this helps
The One With Inifinetely Many Solutions is D. 3x-5=-5+3x are both the same.Meaning that no matter Which Value u Put For X u will get the same Answer On Both Side
