Labron makes $100 per week and takes no vacation during the entire year. his friend, jordan, makes $4800 per year at the same weekly rate. jordan takes x vacation weeks per year.  note: there are 52 weeks in a year. this equation represents how to find jordan’s number of vacation weeks.   100(52 – x) = 4800 labron says that jordan takes 4 weeks of vacation each year. is he correct? check all that apply. yes, he is correct because substituting x = 4 into the equation yielded a true statement. yes, he is correct because substituting x = 4 into the equation yielded a false statement. no, he is incorrect because substituting x = 4 into the equation yielded a true statement. no, he is incorrect because substituting x = 4 into the equation yielded a false statement.

Which fraction below is equivalent to 10/12?

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60

Could somebody me with this radical simplification?
