The length of a table is 8 times longer then it’s width. If the perimeter is 72, how wide is the table?
Andrews [41]

Answer:

4 units wide

Step-by-step explanation:

Let the width of the table be 'w'

Given:

Perimeter of the table is, P=72

The perimeter of the rectangular table is given as the sum of all the sides of the rectangle. The sides include two lengths and two widths.

Length of the table is 8 times longer than its width. Therefore,

Length,L=8w

Now, perimeter is given as:

P=2L +2w\\P=2(8w)+2w\\P=16w+2w\\P=18w\\w=\frac{P}{18}

Now, plug in 72 for 'P' and solve for 'w'. This gives,

w=\frac{P}{18}\\\\w=\frac{72}{18}\\\\w=4

So, the table is 4 units wide.

15 POINTS!!!!!! PLEASE HELP!!The length of a rectangle is four times its width. If the perimeter is at most 130 centimeters, wha
marin [14]
Here is the information we have:

1. The perimeter is at most 130 cm.
2. The length of the rectangle is 4 times the width.
    We can let l stand for length and w for width.

The formula for the perimeter of a rectangle is 2l + 2w.
We have to change the formula a bit.
The length of this rectangle is going to be 4 times the width
So, replace 2l with 2(4w).

Then make this equation equal to 130.

2(4w) + 2w = 130 ; Start
8w + 2w = 130      ; Distribute the 2 across the 4w
10w = 130             ; Combine the like terms 8w and 2w
w = 13                   ; Divide both sides by the coefficient of w. Which is 10

Every day, the Scott Pet Store uses 3 bags of dog food to feed the dogs. For how many days will 1/2 of a bag of dog food last?
nadezda [96]
If you would like to know for how many days will 1/2 of a bag of dog food last, you can calculate this using the following steps:

1 day ... 3 bags of dog food
x days = ? ... 1/2 of a bag of dog food

1 * 1/2 = 3 * x
1/2 = 3 * x         /3
x = 1/2 * 1/3
x = 1/6 of a day

The correct result would be 1/6 of a day.
