What is the length of PR?

d.9 is the length

The reason is because as we have 2 triangles and 21 is divided by 3 we have proof that 27/3=9.

Hope I helped!

You can use deductive reasoning for this. The angle measures are the same so they are similar triangles. This means that they are proportionate. Because the smaller left side is 1/3 the amount of the bigger one, you can assume that the other side follows the same pattern. The smaller side would be 1/3 the size of the bigger side and 1/3 of 27 is 9.

Answer:10%= 310

5%= 155

15%=465

Step-by-step explanation: Solution for what is 15% of 3100

3100/x=100/15

(3100/x)*x=(100/15)*x - we multiply both sides of the equation by x

3100=6.66666666667*x - we divide both sides of the equation by (6.66666666667) to get x

3100/6.66666666667=x

465=x

x=465

What is the sum of the arithmetic series: s10 = -20, d = 4, a1 =?

Otrada [13]

<h2>Step-by-step explanation:</h2><h3> $\green\star$ Given</h3>

$\blue\star$ s10 = -20

$\blue\star$ n = 10

$\blue\star$ an = -20

$\green\star$ solution

$\green\star$ s10 = n\2 [a+(n-1)d]

$\green\star$ -20 = 10a2[a+(10-1)4]

$\green\star$ -4 = a +36

$\green\star$ a1 = -40

$\small\boxed{a = -40}$

steposvetlana [31]

---------------------------------------------
Find slope :
---------------------------------------------
$\text {Slope = } \dfrac{-4 - (-4)}{-7-2} = \dfrac{0}{-9} = 0$

When the slope is 0, the graph is a horizontal line.

Equation of the graph is y = -4
