Mary went up the Old Tower taking 3 steps per second. Then she carefully came down from the tower taking 2 steps per second. It

Gre4nikov [31]

Answer:

The old tower has 150 steps

Step-by-step explanation:

Let the number of steps in the old tower be m

Mathematically, time = distance/speed

In this case, the distance is the number of steps while the speed is the rate of climbing or descending

For climbing, time spent = m/3

For descending time spent = m/2

Since it took her 25 longer when descending;

This means that;

m/2 - m/3 = 25

(3m-2m)/6 = 25

m/6 = 25

m = 6 * 25

m = 150 steps

From a 28-inch by 28-inch piece of metal, squares are cut out of the four corners so that the sides can then be folded up to mak

elixir [45]

Answer:t The volume of the box as a function of x is given by

$Volume=(28-2x)^2x$

Step-by-step explanation:

Since we have given that

Length of metal = 28 inch

Width of metal = 28 inch

Since squares are cut out of the four corners so that the sides can then be folded up to make a box.

Let the length of the sides of the squares that are cut out be 'x'.

So, Length of box would be

$28-2x$

Width of the box would be

$28-2x$

Height of the box would be x.

As we know the formula for "Volume of box":

$Volume=(28-2x)(28-2x)x\\\\Volume=(28-2x)^2x$

Hence, the volume of the box as a function of x is given by

$Volume=(28-2x)^2x$
