A cup of hot water is left out to cool. The water is currently 80c if the heat decreases by 7.4% every minute. What will the temperature be in 6 minute? Round to the nearest degree.

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
