—the graph shows how fast a strand of human hair grows. how many inches would the hair have grown in 5 months

2 and a half @ 2.5 inches (sorry i can't type the fraction)

Step-by-step explanation:

(1/2, 1/4)=(x,y)

based on the graph shown that each grid on the y axis represents 1/4, that is the smallest scale stood in the y axis.

this means 2 grid= 1/4 x 2 = 1/2 @ 0.5 inches.

since the '5 months-hair-length' is above about 2 grid above 2 inch:

2 inch + 0.5 inch= 2.5 inch

there will be 35 boys in each team. : )
