A triangle has the side lengths 5,7 and 11
Assoli18 [71]

To solve this problem you use the "Triangle Inequality Theorem" it states that: any side of a triangle is always shorter than the sum of the other two sides. 

Using this theorem we check each side 

5+7=12: this is greater than the other side which is 11, so this works 

11+7= 18: this is greater than the other side which is 5, so this works 

5 + 11= 16: this is greater that the other side which is 7, so this works

a business owner pays $500 a week for rent.He also pays an employee $16 an hour.If his total weekly expenses are $1,172 ,how man
Ganezh [65]
42 hours

EXPLANATION:

To find the answer, we should start with the total and get rid of the amounts that we know.

So we know the total is 1,172 in a week, and that 500 dollars of it is for rent.

1,172 - 500 =672.

Now we have 672 left.

We know that it was all spent on employees.

we know it is $16 for each hour.

672 divided by 16 is 42 total hours.

Hope this helps!

Given:

Cost of fish dinner = $10.95

selling price of fish dinner = $13.95.

To find:

The percent markup.

Solution:

We know that,

\text{Percent Markup}=\dfrac{\text{Price - Cost}}{\text{Cost}}\times 100

Using this formula, we get

\text{Percent Markup}=\dfrac{13.95-10.95}{10.95}\times 100

\text{Percent Markup}=\dfrac{3}{10.95}\times 100

\text{Percent Markup}=\dfrac{300}{10.95}

\text{Percent Markup}=27.39726

Round to the one decimal place.

\text{Percent Markup}\approx 27.4

Therefore, the markup is 27.4%.
