Answer:

Step-by-step explanation:

First start by simplifying each expression.

To simplify \frac{4}{5} ÷ \frac{1}{12} you can use the method: Keep Change Flip to get \frac{4}{5} × \frac{12}{1}. Now you can simplify to get \frac{48}{5}. Then divide to get the decimal form of 9.6

For the expression: 1\frac{9}{13} ÷ \frac{1}{8}. First you must get both into improper fractions: \frac{22}{13} ÷ \frac{1}{8}. Now you can Keep Change Flip: \frac{22}{13} × \frac{8}{1}. Now multiply: \frac{176}{13}. Now you can divide to get the decimal form of about 13.54

Repeat the steps for the next expression. 1\frac{9}{13} ÷ \frac{1}{12}. Reduce both fractions to improper fractions: \frac{22}{13} ÷ \frac{1}{12}. Not Keep Change Flip: \frac{22}{13} × \frac{12}{1}. Now multiply: \frac{264}{13}. Next divide to get the decimal form of about 20.31.

For the last expression: \frac{4}{5} ÷ \frac{1}{8}. First start by Keep Change Flip: \frac{4}{5} × \frac{8}{1}. Now multiply to get: \frac{32}{5}.  Lastly divide to get the decimal form of 6.4.

Now that you have all decimal forms, you can now put them in order:

1. Least - \frac{4}{5} ÷ \frac{1}{8}

2. \frac{4}{5} ÷ \frac{1}{12}

3. 1\frac{9}{13} ÷ \frac{1}{8}

4. Greatest - 1\frac{9}{13} ÷ \frac{1}{12}

Lines K and N are perpendicular If the slope of line K is -6, what is the slope of Line N
djverab [1.8K]

line N has slope m = \frac{1}{6}

given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m}


thus line N has slope - \frac{1}{- 6} = \frac{1}{6}

Triangle ABC has AB=5, BC=7, and AC=9. D is on AC with BD=5. Find the length of DC
e-lub [12.9K]

Answer:

DC=\frac{8}{3}\ units

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The triangle ABD is an isosceles triangle

because

AB=BD

The segment BM is a perpendicular bisector segment AD

so

<em>In the right triangle ABM</em>

Applying the Pythagorean Theorem

BM^2=AB^2-AM^2

we have

AB=5\ units\\AM=x\ units

substitute

BM^2=5^2-x^2

BM^2=25-x^2 -----> equation A

<em>In the right triangle BMC</em>

Applying the Pythagorean Theorem

BM^2=BC^2-MC^2

we have

BC=7\ units\\MC=AC-AM=(9-x)\ units

substitute

BM^2=7^2-(9-x)^2

BM^2=49-(81-18x+x^2)  

BM^2=49-81+18x-x^2

BM^2=-x^2+18x-32 ----> equation B

equate equation A and equation B

-x^2+18x-32=25-x^2

solve for x

18x=25+32\\18x=57\\\\x=\frac{57}{18}

Simplify

x=\frac{19}{6}

<em>Find the length of DC</em>

DC=AC-2x

substitute the given values

DC=9-2(\frac{19}{6})

DC=9-\frac{19}{3}\\\\DC=\frac{8}{3}\ units

He paid $5.83 to make each shirt and sold each shirt at a marked-up price.
Naddika [18.5K]

we know he made a profit of 1834 for 200 shirts, let's divide those to see how much profit per shirt

\cfrac{1834}{200}\implies \cfrac{917}{100}\implies 9.17

so he made a profit of 9.17 per shirt, now profit is surplus value, value beyond the cost, we know its cost was 5.83 per shirt, so if we take 5.83 to be 100%, how much is 9.17 off of it in percentage?

\begin{array}{ccll} amount&\%\\ \cline{1-2} 5.83&100\\ 9.17&x \end{array}\implies \cfrac{5.83}{9.17}=\cfrac{100}{x}\implies 5.83x=917 \\\\\\ x=\cfrac{917}{5.83}\implies x \approx 157.29
