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
Answer:
y = -7x
Explanation:
Take two points from table: (-4, 28), (-3, 21)
Find slope:
Now find equation:
The container is a cube with side length of 8 cm. If the crystals are also cubes with side length of 1 cm, then 8 crystals will fit along one side of the container. Since all the sides are the same length on a cube, we can take the 8 crystals and cube it to find the total amount of crystals in the container.
= 8·8·8 = 512
Each crystal costs 5 cents, so multiply 512 crystals by $0.05.
0.05(512) = $25.60
Each crystal costs 5 cents, so multiply 512 crystals by $0.05.
0.05(512) = $25.60
