Use rounding to estimate $6.79 - $3.95 to the nearest half dollar

$3.00

Step-by-step explanation:

$6.79-$3.95= 2.84

because 84 is closer to 100 then to 50, round to .00 instead of .50

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
