Answer:
20
Step-by-step explanation:
617/28= 22 (rounded too)
617/32= 19 ( rounded too)
19-22 is teh amount of classes that can be filled with 28 to 32 students.
20 is correct because it is around the amount of classes that there can be. !4 is too little so the number of students should be smaller.
30 and 60 classes are to big. there would only be about 10 or 20 kids per class
2/3 cause you are not changing the number itself so the opposite would just change the negative to a positive.
Answer:
the answer is B
Step-by-step explanation:
it's the right answer
The position equatioin is: s(t) = –16t2<span> + </span>v0t<span> + </span>h0<span>, where </span>v<span>0 </span> represents the initial velocity of the object and h0<span> represents the initial height of the object </span>. So, since the position function represents the height of an object in t seconds, s(t)= h(t). Therefor, v0= intial velocity= 60t. Double 60t and then replace that answer with 60t from Justin's rocket's equation in order to find Pedro's rocket's equation.
