Speed = dis / time
let plane speed in still air is X and air speed Y
so, X-Y = 2280/4 = 570 km/h
and X+Y = 6650/7 = 950 km/h
so, X = (570 + 950) / 2 = 760 km/h
and Y = 950- 760 = 190 km/h

Answer:
317°
Step-by-step explanation:
The total measure of the angles around the center of the circle is 360°. The sum of angles in each half (above AB or below AB) is half that, or 180°. So, the sum of angles below the line is 180°. We can use that fact to find x, then the measures of all of the angles.
(7x +1)° +90° +(9x -7)° = 180°
16x = 96 . . . . . divide by °, subtract 84
x = 6 . . . . . . . . divide by 16
Then angle AOD is ...
(7·6 +1)° = 43°
Short arc AD is 43°, so long arc ACD is 360° -43° = 317°.
arc ACD = 317°
The volume that is left to be filled is approximately: 3,332.6 in.³
<h3>What is the Volume of a Box?</h3>
Volume of a box = (length)(width)(height)
Given the following:
Volume of the bat = 82 cubic in.
Length of box = 30 in.
Width = 18.97 in.
Height = 6 in.
The remaining volume to be filled = volume of box - volume of bat
= (30)(18.97)(6) - 82
= 3,332.6 in.³

Hello!
If this square pyramid originally had a volume of 180 in³, and it is multiplied by ten, we add a zero and get 1800 in³.
I hope this helps!
