\bf \textit{circumference/perimeter of a circle}\\\\ C=\pi d~~ \begin{cases} d=diameter\\[-0.5em] \hrulefill\\ C=314 \end{cases}\implies 314=\pi d\implies \cfrac{314}{\pi }=d \\\\\\ \stackrel{\textit{using }\pi =3.14}{\cfrac{314}{3.14}=d}\implies \cfrac{314}{~~\frac{314}{100}~~}=d\implies \cfrac{\underline{314}}{1}\cdot \cfrac{100}{\underline{314}}=d\implies \boxed{100=d}

What is the equation of a line perpendicular to -x +2=y that intersects the line at (-1.5, 3.5)?​
Nina [5.8K]

Answer:

y=x+5

Step-by-step explanation:

y-y1=m(x-x1)

y=-x+2

slope of y=-x+2 is -1, perpendicular slope is 1

y-3.5=1(x-(-1.5))

y-3.5=x+1.5

y=x+5

Which of the following ratios is equivalent to 49:35?
Arte-miy333 [17]

The best way to find it is to reduce each ratio you work with to its
lowest terms,and see which ones are equal. To reduce a ratio to its
lowest terms, divide each number by their greatest common factor.

First, the one that you're trying to match:  <u>49:35</u> .
The greatest common factor of 49 and 35 is 7 .
Divide each number by 7 . . .  <em>7:5</em> . . . <u>that's</u> what you have to match.

<u>7:4</u>
Their greatest common factor is ' 1 '.
No help at all, and this one is not it.

<u>14:25</u>
Again, their greatest common factor is '1 '.
No help at all, and this one is not it.

<u>21:15</u>
Their greatest common factor is ' 3 '.
Divide both numbers by 3 . . . <em>7:5 </em>.
That's it !
