Please help me.. I'm failing math. :") Maurice is cutting out shapes for a class project. He has a scrap of green poster board in the shape of a triangle, shown below. He wants to trim the large green triangle into a smaller triangle by cutting along the dotted line shown. If the red segment along the left side of the triangle measures 30 cm and the blue segment along the bottom of the triangle measures 54 cm, what is the length of poster board that Maurice cut? (ATTACHED IMAGE IS THE GIVEN TRIANGLE) A) 10 cm

B) 12 cm

C) 20 cm

D) 18 cm

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

In triangle opq right angled at p op=7cm,oq-pq=1 determine the values of sinq and cosq

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.
