Answer:

a. 3/5 liters per hour

b .06 hours

Step-by-step explanation:

Change 40 minutes to a fraction of an hour

40 minutes/ 60 minutes = 2/3 hour

It takes 1 2/3 hours to fill the container

Changing to an improper fraction

(3*1+2)/3 = 5/3 hours

We want liters per hour

1 liter per 5/3 hours

1 ÷ 5/3

Copy dot flip

1 * 3/5 = 3/5 liters per hour

Change 100 ml to liters

We know 1000 ml = 1 lt

100 ml * 1 lt/1000 ml = .1 lt

So 100 ml = .1 lts

.1 lt * 3/5 lt per hour

Changing the fraction to a decimal

.1 lt * .6 lt per hour

.06 hours

Kisachek [45]

Answer:

A. 14x14x28

B. The maximum volume is 5488 cuibic inches

Step-by-step explanation:

The problem states that the box has square ends, so you can express volume with:

$v=x^{2} y$

Using the restriction stated in the problem to get another equation you can substitute in the one above:

$4x+y=84\\\\$

Substituting y whit this equation gives:

$v=x^{2} (84-4x)\\\\v=84x^{2} -4x^{3}$

Now find the limit of x:

$\frac{84x^{2}-4x^{3}}{dx}=168x-12x^{2}\\\\x=\frac{168}{12}=14$

Find the length:

$y=84-4(14)=28$

You can now calculate the maximum volume:

$v=(14)^{2}(28)= 5488$
