Answer:
The dimensions of the box are 38.48 x 14.48 x 5.26 in.
Step-by-step explanation:
We will have a piece of cardboard with squares of side x cut from the corners to make a open box.
The volume of the box can be written as:
To calculate the maximum volume, we derive and equal to zero
We apply the quadratic equation to know the roots of the equation
The first solution is physically impossible, as the side that is cut would be bigger than 25.
So the real solution is for x=5.26 in.
Then, the dimensions of the box are:
Answer:16/20
Step-by-step explanation:
if you divide the two numbers by 4 you have:
16/4=4
20/4=5
(if you divide or multiply both of the numbers with the same number, the ratio will remain the same)
So the two numbers are same

Answer:
A
Step-by-step explanation:
To find how much 3/4 of a number is, multiply 3.4 by the number. Since the book is 7/8 inches thick, Brenden read 3/4 * 7/8.
To multiply fractions, multiply straight across numerator and denominator.
3/4 * 7/8 = 3*7/ 4*8 = 21/32
1 m = 100 cm
Multiply:
100 * 400 = 40000
So she ran 40,000 centimeters.
