The manager of a laudromat ordered 250 bottles of laundry detergent from a supplier for $4,500. Which equation represents the proportional relationship between c, the total cost of the bottles, and n, the number of bottle purchased? A. c = 18 n c = 18 ⁢ n B. n = 18 c n = 18 ⁢ c C. c = 250 n c = 250 ⁢ n D. n = 250 c

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

step-by-step explanation:

if i remember correctly with perpendicular stuff you just take away the negative

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
