The demand for subassembly S is 100 units in week 7. Each unit of S requires 1 unit of T and 2 units of U. Each unit of T requires 2 units of V, 1 unit of W, and 1 unit of X. Finally, each unit of U requires 1 unitof Y and 3 units of Z. One firm manufactures all items. It takes 2 weeks to make S, 1 week to make T, 2 weeks to make U, 1 week to make V, 3 weeks to make W, 1 week to make X, 2 weeks to make Y, and 1week to make Z.a) Choose the correct product structure.○ A.Level0S1○ C.U(2)2 T (1) W (1) X(1) Y(1) Z(3)Level0S1T(1)2 V(2) Y(1) Z (3) W (1) X (1)☑B.Level0ST(1)U(2)12 V(2)W (1) X(1) Y(1) Z(3)→Level0SV(2)☑b) Choose the correct time-phased product structure.○ A.B.ZVUYWT☑Π☑STWYUZ○ C.12 Y(1)W (1) X (1)U(2) Z(3)VW T☑SYUZ☑☑○ D.W T☑SYUZ1 2 3 4 5 6 712 3 4 5671 2 3 4 571 2 3 4 5 67Time in weeksTime in weeksTime in weeksTime in weeks☑

Consider the following approach: At an animal shelter, three types of food are provided for three species of freshwater turtles. Each turtle of species 1 consumes an average of 1 unit of food A, 1 of B and 2 of C per week. Species 2 consumes 1 unit of food A, 4 of B and 5 of C. Species 3 requires 2 units of food A 1 of B and 5 of C. It is known that the shelter can supply weekly 99 units of food A, 181 units B and 320 units of C. If we assume that the turtles consume all the food, indicate the number of turtles of each species that the shelter can maintain. a.

A King in ancient times agreed to reward the inventor of chess with one grain of wheat on the first of the 64 squares of a chessboard. On the second square, the King would place two grains of wheat, on the third square, four grains of wheat, and on the fourth square eight grains of wheat. If the amount of wheat is doubled in this way on each of the remaining squares, how many grains of wheat should be placed on a square 16? Also, find the total number of grains of wheat on the board at this time and their total weight in pounds. (Assume that each grain of wheat weighs 1/7000 pounds.)
1. Two well-mixed tanks are hooked up so that water with 2 pounds of salt per gallon flows into the first tank, well - mixed water flows out of the second tank, water flows from the first tank to the second tank, and water flows from the second tank to the first tank. All flows are constant. Determine how much water is in each of the two tanks, given if x is the amount of salt in the first tank and y is the amount of salt in the second tank then 3x = -x + y + 30 and 6y' 2x - 3y. The answer should be 45 gallons in the first tank and 30 gallons in the second tank. =
