Answer:
the amount of time it takes for approximately 50% of a radioactive atom sample to undergo nuclear decay
Answer:
2000 cm^2/min
Step-by-step explanation:
According to the given question,
12 m^2/h = ? cm^2/min
We know,
1 h = 60 min and 1 m = 100 cm
So, by putting the values we get
- 12 m^2/h = 12 × (100)^2/60
Thus the answer of the given question is 2000 cm^2/min .
So here the denominator is 5 and the numerator is 3. If you double 3, you get 6 and to make the fraction equal to 1, you have to make the denominator 6. So we do 6-5 which is 1
Use proportions because we know that the triangles are similar.

Cross multiply.
20x=28×5
x=7
answer: 7
I think it’s 36, Are there options??
