Andrei Has a glass tank first he wants to put in some marbles each of which has the volume of 0.04 L then he wants to fill the tank with water until it is completely full if he uses 50 marbles he will have to add 33 L of water if Andre has exactly 20 L of water how many marbles does he need so the tank is full?

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
