The quotient of that problem is 30
Answer:
There are 6 halves of the pizza
Step-by-step explanation:
3/0.5=6
The mass of cesium left afer 120 years if the original mass of cesium is 8640 with an half-life of 30 years, is 540 grams.
<h3>What is half-life?</h3>
This can be defined as the time taken for half the amount of a radioactive substance to decay.
To calculate the amount of cesium left after 120 years, we use the formua below.
Formula:
- R' = R/()............. Equation 1
Where:
- R = Original amount of Cesium
- R' = New amount of cesium
- T = Total time
- t = Half-life
From the question,
Given:
- R = 8640
- T = 120 years
- t = 30 years
Substitute these values into equation 1
- R' = 8640/()
- R' = 8640/
- R' = 8640/16
- R' = 540 grams.
Hence, The mass of cesium left afer 120 years is 540 grams.

Answer:
Step-by-step explanation:
scale factor of 10 is an enlargement
scale factor greater then 1 is an enlargement
scale factor between 0 and 1 is a reduction
scale factor of 1 , they stay the same
Hello!
I'm assuming that the values you gave are 18, 12 and 14, but there's a period before the 14, I think that's a mistake but if it's not please let me know, anyhow, the least common multiple of 12, 14 and 18 is 252.
Good luck!
