1% of a number is that number divided by 100. So 60% of a number is 60 times that number divided by 100.In this case, we want 60% of 70. So, we do (7060)/100. This is a rather big fraction, but we can...
a) on the y axis, x=0. sub x=0 into y=A^xtherefore y=A^0 = 1 so A is at (0,1)15) WILL USE DIAGRAMso firstly, we need an equation linking the area of the trian...
With equations, e.g. 4x = 12, the 4x variable has a given value. This means you can apply the same changes to both sides (at the same time). For example, both sides can be divided by 4 to give x=3 H...
