A particular isotope has a half-life of 67 67 days. If you start with 1 1 kilogram of this isotope, how much will remain after 140 140 days? after 280 280 days? The remaining amount after 140 140 days will be nothing kilogram(s). (Round to three decimal places as needed.) The remaining amount after 280 280 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

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
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.
