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:
6/7
Step-by-step explanation:
P(yellow or even) = 3/7 + 3/7 = 6/7
6^2/2(3)+4
Follow the order of operations, (GEMDAS) which goes like this:
<em>grouping, exponents, multiplication/divison, addition/subtraction
</em>
First up is our grouping, specifically parentheses. While we do have parentheses in our expression there isn't anything going on <em>inside</em> of them that we'd have to do first. (The 2(3) is another way of writing 2×3.)
Next we have exponents, which would be our 6^2. (6 squared)
When something is squared, that means it is multiplied by itself. 6^2 = 6×6 = 36.
Now our expression is 36/2(3)+4.
Next we need to handle the multiplication and division. (order doesn't matter)
The best way to do this is from left to right. The 36/2 = 18...
Then 18(3) = 54.
If we took 36(3) then divided by 2 we would get the same answer.
However, what you <em>cannot</em> do is multiply the 2(3), simply because the 2 is a denominator of a fraction. If you don't know what this is or why, it's okay--just always do it left to right and you'll never have to worry about it.
Now our expression is 54+4.
Finally, we can handle the addition/subtraction. 54+4 leaves us with 58.
1 kg = 1 * 10 ^ 3 g
kilo = 10^3
