Answers
Let S=the amount of radium you start with
Let t=the amount of time in years
Let h=the half-life time
Then A=S(1/2)^(t/h)
So,
A=80(1/2)^(430/1690)
A=approx. 67g

Answers
Answer:
take out the a with an equation
The solution of x is y+4b/9a for equation y=9ax-4b
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is y=9ax-4b
y equal to nine times of and x minus four times of b.
We need to solve for x
Add 4b on both sides
y+4b=9ax-4b+4b
y+4b=9ax
Divide both sides by 9a to separate x on RHS
y+4b/9a=x
Hence the solution of x is y+4b/9a for equation y=9ax-4b

Cheddar cheese cost 4.25 per pound. Which equation best represents y, the cost of x pound of cheddar cheese
Answers
Answer:
y = 4.25x
Step-by-step explanation:
Cheddar cheese cost 4.25 per pound . This means the cost of cheddar cheese is 4.25 for every pound in weight. Assuming we put a currency to the value we can say 1 pound of cheddar cheese is equals to 4.25 dollars($4.25). Mathematically, it can be represented as
4.25 is the cost for 1 pound of Cheddar cheese
Let the cost of the equation be y as required from the question.
y = cost of the cheddar cheese
x is the weight value in pounds of the Cheddar cheese.
The equation can be best represented as
y = 4.25x
In the equation above if the amount in pounds is 3 pound . the value will be inputted for x and the cost will be gotten which is y.

Given:
Number of sides = 7
Apothem = 8 meters
Side length = 7.7 meters
To find:
The area of the regular polygon.
Solution:
We know that,
Area of a regular polygon is
[tex]A=\dfrac{1}{2}pa[/tex] ...(i)
where, p is perimeter and a is apothem.
Perimeter of a regular polygon is the product of number of sides and side length.
[tex]p=7\times 7.7[/tex]
[tex]p=53.9[/tex]
Substituting p=53.9 and a=8 in (i), we get
[tex]A=\dfrac{1}{2}(53.9)(8)[/tex]
[tex]A=(53.9)(4)[/tex]
[tex]A=215.6[/tex]
Therefore, the area of the regular polygon is 215.6 m².
