I am trying to assess where I am in my current physics class but since his grading system is different than most, I am not sure where I stand.

My quiz cumulative grade is 72% and is worth 25% of my grade

My average test score is 60% and is worth 30% of my grade.

My homework average is 80% and is worth 5% of my grade.

I still have a final to take which is worth 40% of my grade.

Can you tell me what my current grade is and what I have to make on the final to get a 70%?

Thanks for any help.

This is a question given to me by an ex WWII engineer a few years back as a challenge to me. It took me quite some time to figure out. Thought it might be found an interesting question and challenge.

If you have a cylinder of radius r and with a drill of the same radius you drill it so that it JUST breaks in half. How much volume of material have you removed?

I understand this question partially, but i'm not sure where my teacher got A=x^2+xy

Here's the question:

A farmer wishes to build two enclosures using fencing. One enclosure must be a square, and the second must be a rectangle with the length of one side equal to the side length of
the square. The two enclosure are not connected. 1000 m of fencing is available for the project

1a. Let x represent the side length of the square and A(x) the total area of both enclosures as a function of x. Find a formula fot A(x).

1b. Find the dimensions of the square and rectangle which enclose the largest area possible. (The solution may appear obvious to you, but prove it using A(x) from part (a).)

Thank you!
