B) Use the formula v= u + at to find the velocity, when
the initial velocity is 3 m/s
• the acceleration is 1.5 m/s2
• the time is 7 seconds

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

answer: b.36 feet

step-by-step explanation:

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
