Answer:0.75 milligrams will be present in 24 hours
Step-by-step explanation:
Step 1
The formula for radioactive decay can be written as
N(t)=No (1/2)^(t/t 1/2)
where
No= The amount of the radioactive substance at time=0=milligrams
t 1/2= the half-life= 6 hours
t=24 hours
N(t) = the amount at time t
Step 2--- Solving
N(t)=No (1/2)^(t/t 1/2)
=N(t)=12 x ( 1/2) ^ (24/6)
= 12 x (1/2) ^4
= 12 x 0.0625
= 0.75 milligrams
Answer:
Yes.
Step-by-step explanation:
The two triangles are <em>similar</em> because they have:
- a common angle (90°)
- corresponding sides with lengths in a 3:1 ratio
All you need to do is to slide the smaller triangle into the larger one so that a small angle and one of its sides coincide.
Then the hypotenuses of each triangle will lie along the same line.
36/15 = 12/5
x^5 / x^5 = 1
y^8 / y^7 = y
z^10 / z^2 = z^8
Answer is 12yz^8/5
Answer:
384
Step-by-step explanation:
If 48 is 50% of something, that means
48 + 48 = 96. Now, what number is 96 25% of? well 96 • 4 = 384. Now let's do the math backwards!
25 % of 384 is 96. 50 % of 96 is 48! so your answer is 384! Hope this helps!!!
Answer:
32
Step-by-step explanation:
divide 1320 by 8 to see how many feet per minute and then divide that number by 5,280 ft to see your final answer.
