A watercolor painting is 24 inches long by 11 inches wide. Ramon makes a border around the watercolor painting by making a mat t

sergeinik [125]

Given: It is given that the length of the painting is 24 inches and the width is 11 inches.

To find: Area of the mat

Solution:

The watercolor painting is 24 inches long by 11 inches wide.

So, the area of the painting is:

$\text{Area of painting}=l\times b$

$\text{Area of painting}=24\times 11$

$\text{Area of painting}=264 \text{ in}^2$

The length of painting with mat is = 24 in + 3 in + 3 in = 30 in

The width of painting with mat = 11 in + 3 in + 3 in = 17 in

$\text{Area of painting with mat}=30\times 17$

$\text{Area of painting with mat}=510 \text{ in}^2$

Now to calculate the area of mat subtracts the area of painting from the area of the mat.

$\text{Area of mat}=\text{Area of painting with mat}-\text{Area of painting}\\$

$\text{Area of mat}=510-264$

$\text{Area of mat}=246 \text{ in}^2$

Hence, the area of the mat is 246 in².

If you have 100 entries out of 1200 what are your chances

swat32

100/1200= x/100
cross multiply

(1200 * x)= (100 * 100)

1200x= 10000
divide both sides by 1200

x= 8.333% winning chance

LOSING CHANCE
100% - 8.333%= 91.667%

RATIO OF WINNING TO LOSING
100 tickets= winning chance
1200 total - 100= 1100 losing chance

100:1100
simplify by 100

1:11 odds of winning to losing

ANSWER: The chance of winning is 8.333% and the chance of losing is 91.667% or 1:11.

Hope this helps! :)
