Circumference of circle=<span>2πr</span>

Where <span>r=radius</span>

<span>2r=d</span>

<span>d=diameter</span>

So,<span>2πr=πd</span>

Note,<span>π=<span>227</span></span>

In this statement,<span>c=ci</span><span>rcumference</span>

<span>→c=πd</span>

<span>→c=π<span>(30)</span></span>

<span>→c=π30=<span>227</span><span>(30)</span></span>

<span>→c=<span>6607</span>=94.28...</span>

Circumference is <span>94.28...cm<span>s</span></span>

Stan's, marks, and wayne's ages are consecutive whole numbers. stan is the youngest, and wayne is the oldest. the sum of their a
White raven [17]

Stan's, Mark's and Wayne's ages are 35 , 36 and 37 years respectively.

<em><u>Explanation</u></em>

Stan's, Mark's and Wayne's ages are <u>consecutive whole numbers</u> and Stan is the youngest and Wayne is the oldest.

So, lets assume that Stan's, Mark's and Wayne's ages are  n, n+1 and n+2

Given that, the sum of their ages is 108. So, the equation will be.....

n+(n+1)+(n+2)=108\\ \\ 3n+3=108\\ \\ 3n=108-3=105\\ \\ n=\frac{105}{3}=35

So, Stan's age is 35 years , Mark's age is (35+1)= 36 years and Wayne's age is (35+2)= 37 years.

Answer:

D. y = { -x + 2 x ≥ 1}

          { x + 1  x < 1}

Step-by-step explanation:

First is to eliminate A and C, why?

This is because of the end points shown on the graph.

As shown, if you look at the point of (2,1) it is black, this means that not only is it closed but it is also means ≤ or ≥ symbol.

You are now left with B and D

The difference between these two is the symbols; they are facing the opposite directions.

While B says x ≤ 1, and x > 1

While D says x ≥ 1, and x < 1

The direction of the symbols depends on the direction of the lines and what is part of it (some what like a shaded area)

So you answer would be D

Rename fraction 2/5 so you can add it to 11/25. Find the sum.
Slav-nsk [51]
\frac{2}{5}+ \frac{11}{25}=x \\  \\  \frac{(5)2}{(5)5} + \frac{11}{25}  \\  \\  \frac{10}{25} + \frac{11}{25} \\  \\  \frac{10+11}{25} \\  \\ \boxed { \frac{21}{25}}
