A particular isotope has a half-life of 77 77 days. If you start with 1 1 kilogram of this isotope, how much will remain after 150 150 days? after 300 300 days? The remaining amount after 150 150 days will be nothing kilogram(s). (Round to three decimal places as needed.) The remaining amount after 300 300 days will be nothing kilogram(s). (Round to three decimal places as needed.)
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance

Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
