Answer: I have no Idea how your teacher got 75.4 but if you go on goo gle and search "lateral area of a cone" there is a type of calculator thing at the top. Just type 2 where it says r - radius and 12 where it says h - height. The answer should be 76.4 so I'm assuming it's A.
Mrs brown will need to pay off 55$ to have her credit card statement 0$
Part A. 250+45a=t
That's because 'a' is the variable in which we don't know how many appointments she will have. 'a' times the $45 would be in the equation. Then you would have to add the $250 for the tests and medicines.So 250+45a=t
Part B.(250+45a)-(25%*t).
That's because the first set in parentheses is the total cost. You would have to subtract that buy the discount times the total cost which represents the the second set of the equation.:)
Part C.25%*6 appointments equals 1.5. You have to solve (250+45) and then multiply 25%*6.That product plus (250+45) would be your final answer.U won't tell you the answer because it would help.U would need explanation.This is how I would answer the question.Hope this helped
