Answer:
Step-by-step explanation:
Perimeter = 2(l + w)
l = 8.5cm, perimeter = 24cm
24 = 2(8.5 + w)
Dividing through by 2
24/2 = 8.5 + w
12 = 8.5 + w
W = 12 - 8.5
W = 3.5cm
The answer would be B 21/4
Sorry I can't solve it.
Firstly, the equation is wrong. It is supposed to be <span>81 ≠ </span><span>30.25
Second of all, this is the best I got </span>81= <span><span>−<span>76 <span>(<span>cos<span>(r) </span></span></span></span></span>+ <span>106.25</span></span>
The problem deals with a division and the rest of it, that is dividing the total amount of pencils into 9 classrooms and the rest, lets express it as fraction:
935/9 = 103 + 8/9
that is, if we multiply 103*9 we get 927 and are 8 pencils left over, therefore, 8 pencils are donated to the library and each classroom gets 103 pencils, in total 935 pencils are donated.
