How much of a radioactive kind of antimony will be left after 120 days if you start with 904 grams and the half-life is 60 days?
==========================================
Explanation:
1/2 = 0.5
Every 60 days, the amount cuts in half.
We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.
After another 60 days, we have 452*0.5 = 226 grams left over.
-------------
Alternative Method:
We can apply the half-life formula.
y = a*(0.5)^(x/H)
where,
y = final amount after x daysa = initial amountx = number of days that elapseH = number of days in a half-lifeIn this case,
a = 904 is the starting amountH = 60 is the number of days until another half-life occursWhen x = 120 days go by, we have....
y = a*(0.5)^(x/H)
y = 904*(0.5)^(x/60)
y = 904*(0.5)^(120/60)
y = 904*(0.5)^(2)
y = 904*(0.25)
y = 226 grams of antimony left over.
This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.

what is the range of the following numbers
12, 20, 18, 25, 6
Answer:
The answer is 19
Step-by-step explanation:
Range is the difference between the largest and smallest number, so in this case the largest number is 25 and the smallest number is 6. Subtract 25 and 6 to get the range. So the answer would be, The range of the following numbers is 19.

Answer:
[tex]y=\frac{1}{2}[/tex]
Step-by-step explanation:
[tex]4(y+1)= \frac{3}{1-y}[/tex]
[tex]4y+4= \frac{3}{1-y}[/tex]
[tex](4y+4)(1-y)= 3[/tex]
[tex]4y(1-y)+4(1-y)=3[/tex]
[tex]4y-4y^{2} +4-4y=3[/tex]
[tex]-4y^{2}=3-4[/tex]
[tex]4y^{2}=1[/tex]
[tex]y^{2} = \frac{1}{4}[/tex]
[tex]y=\sqrt{\frac{1}{4} }[/tex]

Answer:
15x^2-14x-4
Step-by-step explanation:
(8x^2 * x-7x+2)+(7x^2 -7x-6)
you take out the parentheses
you add the common ones so -7x+-7x= -14x
8x^2 +7x^2 = 15x^2
and 2-6= -4
so in total it's 15x^2-14x-4
Answer: 11x^2 -16x-3
Step-by-step explanation:
Solution:
Your problem → (8x^2-7x+2) + (3x^2-9x-5)
(8x2-7x+2)+(3x2-9x-5)
=8x2-7x+2+3x2-9x-5
=8x2+3x2-7x-9x+2-5
=11x2-16x-3
Solve for h.
h/10 + 5 = 25
so what’s h ??
Answer:
h=200
Step-by-step explanation:
h/10+5=25
h/10=20
h=200
h/10 + 5 = 25
Subtract 5 from each side to get h/10 alone.
h/10 + 5 - 5 = 25 - 5
h/10 = 20
Multiply both sides by 10 to get h alone.
h/10 • 10 = 20 • 10
h = 200
h = 200. I hope this helps!
