On her birthday, Sonia distributed chocolates in an orphanage. She gave 5 chocolates to each child and 20 chocolates to adults.
1 answer:
Answer with explanation:
Total number of Children = x Children
Total number of chocolates distributed = y Chocolates
If there are x children, then total number of chocolate got by children= 5 x Chocolate
Number of chocolate got by Adults= 20
Let total number of adults be z.
Expressing the statement in terms of Equation
y = 5 x + 20 z
⇒Number of Adults =z

<h2>Dimension of box is 2 m x 2 m x 1.33 m</h2>
Step-by-step explanation:
Let a be base side and h be the height.
Volume of box, V = a²h
The sides of the box will cost $3 per m² and the base will cost $4 per m². Cost for making is $48.
That is
4a² + 3 x 4 x a x h = 48
4a² + 12 a x h = 48
a² + 3 ah = 12
So volume is
At maximum volume we have derivative is zero,
Negative side is not possible, hence side of square base is 2m.
Substituting in a² + 3 ah = 12
2² + 3 x 2 x h = 12
h = 1.33 m
Dimension of box is 2 m x 2 m x 1.33 m
