HELP PLEASE Ms. Grimes is grading student responses for the same math problem. Three student responses are shown.
Student A: 0 Student B: 1 / 2 Student C: 7
If Ms. Grimes' answer key says the correct answer should be 2 which student answer(s) is/are correct? Select the best
response below that represents the
O A Student A is the only student correct because you cannot have a negative sign in the numerator or denominator and Student A's
response closely matches the response of Ms. Grimes.
OB. None of the students were correct because Ms. Grimes did not have parentheses in her response and the negative sign was not in
the numerator or denominator.
OC All the students are correct because each response is equivalent.
O D. Student B and Student Care correct because the negative sign in Ms. Grimes' response means that the negative sign could only be
in the numerator or the denominator.

How many ordered pairs of positive integers satisfy xy=32?

Aflagpole broke in a storm. it was originally 8 1 81 feet tall. 2 8 28 feet are still sticking straight out of the ground, where it snapped, but the remaining piece has hinged over and touches the ground some distance away. how far away is the end of the pole from the base of the pole along the ground?

Acaterer knows he will need 60, 50, 80, 40 and 50 dinner napkins on five successive evenings. he can purchase new napkins initially at 25 cents each, after which he can have dirty napkins laundered by a fast one-day laundry service (i.e., dirty napkins given at the end of the day will be ready for use the following day) at 15 cents each, or by a slow two-day service at 8 cents each or both. the caterer wants to know how many napkins he should purchase initially and how many dirty napkins should be laundered by fast and slow service on each of the days in order to minimize his total costs. formulate the caterer’s problem as a linear program as follows (you must state any assumptions you make): a. define all variables clearly. how many are there? b. write out the constraints that must be satisfied, briefly explaining each. (do not simplify.) write out the objective function to be minimized. (do not simplify.)
