The U. S. government spent nearly $10 billion planning and developing a nuclear waste facility at Yucca Mountain (Nevada), though the project was cancelled in 2011. The intent had been for the facility to store up to 77,000 metric tons of nuclear waste safely for at least 1 million years. Suppose it had been successful and stored the maximum amount of waste in the form of plutonium-239 with a half-life of 24,000 years. How much plutonium would have remained after 1 million years?

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
