Step-by-step explanation:
A = A₀ ½^(t / T)
where A is the amount left, A₀ is the original amount, t is time, and T is the half life.
4 days is 96 hours, so the amount left is:
A = 600 ½^(96 / 15)
Answer:
do i round to the nearest hundredth?if so it would be 0.11
Step-by-step explanation:
2x - 3y = -2 ⇒ 4x - 6y = -4
4x + y = 24 ⇒ <u>4x + y = 24</u>
<u>-7y</u> = <u>-28</u>
-7 -7
y = 4
2x - 3(4) = -2
2x - 12 = -2
<u> +12 +12</u>
<u>2x</u> = <u>12</u>
2 2
x = 6
(x, y) = (6, 4)
Answer: Internet
Step-by-step explanation:
I don’t know exactly how to do this but I could probably help you try looking on the Internet maybe that would help so I guess I’ll just help you you’re welcome
It would be 6:24 but simplify it to 1:4. I do not understand about what you mean by fraction and decimal. Maybe you could rephrase your question?
