Chang added some chlorine to the water in a pool. The chlorine evaporated at a fixed rate every week. The table below shows the amount of chlorine f(n), in ounces, that was left in the pool after n weeks: n f(n) 1 24 2 12 3 6 4 3 Which function best shows the relationship between n and f(n)? f(n) = 48(0.5)n − 1 f(n) = 24(0.5)n f(n) = 24(0.5)n − 1 f(n) = 48(0.5)n + 1

hi

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
