For a science experiment, Mr. Barrows divided 1/2 cups of salt into small jars, each clothing 1/10 cup. If he has 1/9 cup of salt left over, how many jars dose he fill?

Number of jars filled is 3 (approximately 4).

Step-by-step explanation:

Initial amount of salt = 1/2 cup.

Amount of salt left = 1/9 cup.

Amount of salt used = 1/2 - 1/9

                                  =

                                  = 7/18

The size of each jar = 1/10 cup.

Amount of salt used = size of the each jar x number of jars filled

7/18 = 1/10 x number of jars filled

number of jars filled = 7/18 ÷ 1/10

                                  = 7/18 x 10/1

                                  = 70/18

                                  = 3

                                  = 3.9

The number of jars filled is approximately 4.

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
