Answer:
39 mg
Step-by-step explanation:
To get the number of milligrams, all we have to do is to find 130% of the RDA
mathematically, we have this as;
130% of 30
= 130/100 * 30 = 39 mg
Answer:3×x=15

Step-by-step explanation:
Answer:
Step-by-step explanation: the area of the circle is A=r%5E2%2Api
if x is the radius of the large circle, then r=x and the area of the larger circle is
A=x%5E2%2Api
and if x is the diameter of the small circle,then r=x%2F2 and the area of the smaller circle is
A=%28x%2F2%29%5E2%2Api->A=%28x%5E2%2F4%29%2Api
The number of fish decreases by x% each year. x% can also be written as 0.01x.
If the total number of fish in a lake is A, after one year the number of fish will be:

After two years the number of fish will be:

So, the general formula for the number of fish after n years can be written as:

It is given that after 8 years, the number of fish is reduced to half. So we can write:
This means the value of x is 8.3%. So, the number of fish in a lake decreases by 8.3% each year
