Answer is A)340


There are 3000 rhino. Population will grow by 10% so u will have =3,300 rhinos after 1 year.

Total acres reqd will be= 330,000 +10,000 (for water)= 340,000

Answer is 50%. Use 100 as original retail price After discount price= 80 cost*1.2=80 cost= 80/1.2= 200/3=66.6 If sold at 100 profit will be= 100-200/3= 100/3=33.3 Profit % if sold at original price= (33.3/66.6)*100= 50% I suggest in such case sstart with 100 and move from there onwards. makes it muc...

sides are: x, x, √2x where hyp=√2x perimeter= 2x+ √2x= √2x(√2+1) √2x (√2+1)= 16+16√2= 16(1+√2) √2x= 16(1+√2)/ (1+√2) = 16 hyp=√2x=16 You can also use POE to get the answer

aim-wsc, i don't get that how can we cancel E.

if I am paying less tax then my neighbor then doesn't it prove that some people are benefiting more from PP 13 than others. Hence, E seems logical.
