So -3 is -(-3) and the opposite of -3 is 3.
so 3 is your anwser.
Answer:
18×18×36
Step-by-step explanation:
According to the Question
108≥ 4h + w
Volume V is given by
V = wh^2
⇒V= (108-4h)h^2
⇒V= 108h^2 - 4h^3
Now differentiating and keeping = 0 we get
V' = 216h - 12h^2 = 0
h = 216/12 = 18
w = 108 - 4×18 = 36
V = 36×18^2 = 11664 from a box of 18×18×36.
40% of 400 would be 160.
40% is 0.4
so
0.4*400 = 160
to prove my work
400/160 = 0.4 = 40%
#1: 15%
#2: 1/10 = 10%
There are 6 girls who have blonde hair out of 40 students; 6/40 = 15%.
There are 4 boys that have black hair out of 40 students; 4/40 = 1/10 = 10%.
