The field Archie will cover with grass seed is rectangular and measures 100 yards long by 60 yards wide.
B. Write an equation that describes the relationship between the number of
square yards (x) of ground to be covered and the number of scoops () of
grass seed needed. Use the equation to determine the number of scoops
of grass seed Archie needs to cover the entire field. Show or explain all
your work.

Which rational number could be graphed between -4 and -5

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

Are the corresponding angles congruent? explain why or why not.
