I need to find the measure of angle LMN.

sergiy2304 [10]

Notice the circle, the radius NM or ML is 5, and the arc the angle makes is 14.3 cm, thus

$\bf \textit{arc's legnth}\\\\
s=\cfrac{\pi \theta r}{180}\quad 
\begin{cases}
r=5\\
s=14.3\\
\theta =angle~in\\
\qquad degrees
\end{cases}\implies 14.3=\cfrac{\pi \theta 5}{180}\implies \cfrac{14.3\cdot 180}{5\pi }=\theta$

4. Which of the following expressions represents the perimeter of the figure below?

Alexxx [7]

<h2>Explanation:</h2><h2 />

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll help you assuming some things. First of all, for a two dimensional shape, the perimeter is defined as the distance around it. Suppose we have a rectangle whose dimensions are:

$l=4x+9 \\ \\ w=2x-19 \\ \\ \\ l:Length \\ \\ w:Width \\ \\ \\ \text{So the perimeter is:} \\ \\ P=2l+2w \\ \\ P=2(4x+9)+2(x-19) \\ \\ P=8x+18+2x-38 \\ \\ P=(8x+2x)+(18-38) \\ \\ \boxed{P=10x-20}$

So in this context:

Correct option is D. 10x - 20

Change the mixed number to percentage<br><br> 7 7/8

ludmilkaskok [199]

Well, the idea being, that 1 is the 100% unit, so say 0.5 is 50% and so on.

so, let's convert 7 and 7/8 from mixed to improper first.

$\bf 7\frac{7}{8}\implies \cfrac{7\cdot 8+7}{8}\implies \cfrac{63}{8}\implies 7.875\\\\
-------------------------------\\\\
\begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1&100\\
7.875&p
\end{array}\implies \cfrac{1}{7.875}=\cfrac{100}{p}\implies p=\cfrac{7.875\cdot 100}{1}$

Answer:

Step-by-step explanation:

For this, you want to find the greatest common factor

This basically means what number can be divided out of all of these.

So, you can find the factors for all of them and find which one appears in all three numbers and which is the greatest number

for 12:

1, 2, 3, 4, 6, 12

For 20:

1, 2, 4, 5, 10, 20

For 56:

1, 2, 4, 7, 8, 14, 28, 56

The numbers that appear in all of there are:

1, 2, and 4

And since we want to find the greatest amount she can charge for bracelet, the answer is:
