(a) 4/(4+5)= 4/9

(b) Simply multiply 120 by 7, which makes 840. Reason: (1/7)*x=120

Anyone.....plz answer this:
Q. A sports club wishes to use 720 m of fencing to make six equal-sized rectangular courts placed adjacent to each other as shown in the diagram. Given that each court measures x m by y m, show that the total area of all six courts, A m^2, is given by A=3/4(720x-9x^2). Given that x and y may vary, find the dimensions of each court for which A is a maximum.

either you linked the wrong paper, or you seriously need to open the maths book

Time and Limits of Accuracy will be the chapters.

for the time question you have to multiply that number by sixty.

for the other.. you have to first find the upper bound .. which is 1.55kg then multiply it with 1000 to get the answer.
