The shaded part is four little blocks, and its area is ' 1 '.
So the area of each little block is 1/4 .
The part with crosses covers two little blocks.
So its area is (2 x 1/4) = 1/2 .
Let the relative speed will be given by:
38/4=9.5 km/h
Let the speed of the first tourist be x km/h
the speed of the second one is (9.5-x) km/h
distance covered by the first one is:
4*x+2=4x+2 km
distance covered by the second one is:
(9.5-x)4 km
=(38+4x) km
total distance will be given by:
(38+4x)+(4x+2)=38
40+8x=38
8x=-2
x=-1/4 km/h
this mean that he was traveling in the opposite direct thus the speed was 1/4 km/k
The speed of the second one will be:
9.5-1/4=9.25 km/h
The answer is B. use parchment paper and place it over the graph draw the shape and x and y axis on the parchment paper and rotate it. the first rotation us 90° the second is 180° the third is 270° and the fourth is 360°.
The possible values that a probability can have ranges from 0 to 1 inclusive.
Area = side length²
Because it's a square, all of the side lengths are equal.
15 = s²
s = √(15)
s = √(15) inches
Hope this helps!
