14 out of 20 students pack their lunches. what percent of students pack their lunches?

1 answer:

7 0

Think of it as a fraction (14/20). If you multiply 20 by 5, you get 100. Whatever you do to the bottom, you have to do to the top. So 14 x 5 would be 70. The entire fraction would be 70/100 or 70%.

The specifications for a new cardboard container require that the width for the container be 4 inches less than the length and t

Levart [38]

Answer:

c) Length = 12, width = 8 and height = 23.

Step-by-step explanation:

Let the length be x, then the width = x - 4 and the height = 2x - 1.

a) The polynomial is x(x - 4)(2x - 1)

b) x(x - 4)(2x - 1) = 2208

c) x(x - 4)(2x - 1) - 2280 = 0

2x^3 - 9x^2 + 4x - 2280 = 0

I'll use graphical software to find a solution for this. Its easily obtained online.

There is one real root and its x = 12.

So the dimensions of the box are L = 12, W = 8 and H = 23 inches.
