The student would get an 80%.
Since 5 is 20% of 25, subtract 20 from 100 and you get 80%
so, you just use the x's from the table and plug them into the equation to find the y.
y=(1)+9
y=10
y=(2)+9
y=11
y=(3)+9
y=12
y=(4)+9
y=13
i hope this helps :)
Take the 4cm side and the 6cm side.
If you hook them together at one end, then there's no way they can reach the ends of the 11cm side. The farthest they can reach is 10cm.
That's what choice-B says.
