Answer:
- 4/15
Step-by-step explanation:
Just take 4 and 15 make that a fraction make the fraction a negative not the 15 because they will be the same thing no matter where you place it
After 1 hour, 360 g decays to 180 g.
After another hour (total 2 hours), 180 g decays to 90 g.
After another hour (total 3), 90 g decays to 45 g.
After one more (total 4), 45 g decays to 22.5 g.
More quickly, with a half-life of 1 hour, the 360 g of starting material decays to
(360 g) / 2⁴ = 22.5 g
In general, if the half-life is 1 hour, then after <em>n</em> hours, an initial amount <em>A</em> of this substance decays according to
<em>A</em> / 2<em>ⁿ</em>
I got you- The answer is (B. 4) hope this helps, if you need me to explain ask in the comments. Have a good day/night:)
Answer:
e ^1/2
Step-by-step explanation:
All you do is take the fraction (4/8) and just simplify that part
4 divided by 2 = 2
8 divided by 2 =4
I got 2/4 but I can simplify more
2 divided by 2= 1
4 divided by 2 = 2
Now I got 1/2
And I would just leave e alone so my answer is e ^1/2
Do you kinda get what im saying?
The factors of 25 and 60 would be 5. 25 divided by 5 is 5 and 60 divided by 5 is 12.
So here is what the distributive property looks like.
a(b+c)=a*b+a*c but we are going to rewrite a*b and a*c as 5*5 and 12* 5
a(b+c)=5*5+12*5
So i'd say its 5*5+5*12 i hope this helps
