Activity Trey made a scale drawing of a microchip using a scale of 2 inches to 1 centimeter. His drawing was an enlargement that
depicted the chip as 6 inches long and 4 Inches wide. However, the drawing Isn't big enough to clearly show all of the chip's
components. So he wants to make the drawing larger.
Complete the steps below to figure the dimensions of the scale drawing if Trey changes the scale to 3 inches to 1 centimeter.
Part A
What is the actual length of the microchip?

Nine more than four times a number is the same as one less than twice the number. find the number?

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.)

In the diagram, ab is tangent to c, ab = 4 inches, and ad = 2 inches. find the radius of the circle.
