Question

kareems mother measured his height each school year. use the rulers to answer the questions. write each answer as a whole number or decimal (not a fraction). (a) how much taller did kareem grow from one year to the next? cm (b) at this rate, how tall will kareem be in 11th grade? cm

Explanation:

Step1: Find the growth per year

From 5th to 6th grade: \(134 - 128=6\) cm. From 6th to 7th grade: \(140 - 134 = 6\) cm. So the growth per year is \(6\) cm.

Step2: Calculate height in 11th grade

From 7th to 11th grade is \(11 - 7=4\) years. Current height (7th grade) is \(140\) cm. Height in 11th grade: \(140+4\times6=140 + 24=164\) cm.

Answer:

(a) \(6\) cm
(b) \(164\) cm
