The answer is D 75% of the original volume is left.
Answer:
<em>15 people</em>
Step-by-step explanation:
since Raul and his friends each weigh 1/20 ton,
and the total weight reads 3/4 ton
The total number pf people on the scale will be:
<em>The total weight of Raul and his friends divided by their individual weight</em>
==> (3/4 ton) ÷ (1/20 ton)
= 3/4 X 20/1 = <em>15 people</em>
F'=(8,7)
G'=(1,1)
H'=(4,8)
**tips: 270 counterclockwise=90 clockwise
if the question is 90 or 270 (counter)clockwise, just exchange the original x and y coordinates and check which area the point is changed to then apply the right sign (+/-) to the coordinates, and if the question is 180 (counter)clockwise, no need to exchange the original coordinates, just check the sign is alright :)
P.S. i hope you could understand what i m saying, cuz i m not a native english speaker so my english may not be good, sorry for that :p
