Marie 2,480 windows Marie washed 4 times as many windows as Elizabeth Elizabeth washed the same number of windows each day over

vlada-n [284]

Answer:

Elizabeth washes 99 windows each day.

Step-by-step explanation:

Given:

Total number of windows (N) = 2480

Marie washes windows = 4 times Elizabeth washes.

Elizabeth washes same number of windows for 5 days.

Let the number of windows washed by Elizabeth each day = 'x'.

Therefore, over the 5 days, the windows washed by Elizabeth = $5x$

Now, as per question:

Marie washes windows = 4 times Elizabeth washes.

So, number of windows washed by Marie = $4(5x)=20x$

Now, total number of windows = Windows washed by Marie + Windows washed by Elizabeth

So,

$2480=20x+5x\\\\2480=25x\\\\x=\frac{2480}{25}\approx99$

Therefore, Elizabeth washes 99 windows each day.

The length of a rectangular storage room is 3 feet longer than its width. if the area of the room is 40 square feet, find the wi

xenn [34]

Answer:

Width of rectangular storage room= 5 feet.

Step-by-step explanation:

Let x be the width of storage room.

We have been given that the length of a rectangular storage room is 3 feet longer than its width. So the length of storage room will be x+3.

We are also given that the area of the room is 40 square feet.

Since the area of a rectangle is length times width.

$\text{Area of rectangle}=\text{Length* Width}$

Let us substitute our given values in area formula.

$40=x*(x+3)$

Upon distributing x we will get,

$40=x^2+3x$

$x^2+3x-40=0$

Now let us factor out our quadratic equation using splitting the middle term.

$x^2+8x-5x-40=0$

$x(x+8)-5(x+8)=0$

$(x+8)(x-5)=0$

$x+8=0$ or $x-5=0$

$x=-8$ or $x=5$

Since width can not be negative, therefore, the width of rectangle will be 5 feet.

Let us verify our answer.

Length of rectangular storage room is 3 feet longer than its width. So length will be 5+3=8.

Given: Area=40 square feet.

5*8=40.

Hence, width of rectangular storage room is 5 feet.
