Answer:
The fraction of all shapes which are square in shape is .
Step-by-step explanation:
Given that , in a game , white and black shapes are used. Some of them are circle in shape and remains are square in shape.
The ratio of white to black shapes are 5:11.
Consider 5x= the number of shapes which are white in color.
11x= The number of shapes which are black in color.
There are (5x+11x)= 16x shapes in the game.
The white circle and white square are in the ratio 3:7.
The number of white square is
The black circles and black square are in the ratio 3:8
The number of black square is
=8x
Therefore the total number of shape which are square is
The fraction of all shape are square is
The table is missing, so i have attached it.
Also, the correct question is;
The surface area of the East China Sea is k times the surface area of the Baltic Sea.
Work out the value of k.
Give your answer to the nearest whole number
Answer:
k = 3
Step-by-step explanation:
From the attached table,
Surface area of east china = 1.25 × 10^(6) km²
Surface area of Baltic sea = 4.22 × 10^(5) km² = 0.422 × 10^(6) km²
We are told that the surface area of East China Sea is k times that of the surface area of the Baltic Sea.
Thus;
1.25 × 10^(6) = k × 0.422 × 10^(6)
k = 1.25/0.422
k = 2.96
Approximating to whole number gives;
k = 3
