What is the circumference of a circle with a radius of 2.5 m?

mixer [17]

The circumference of a circle is always calculated by 2 $\pi$ R
So if R=2.5 m this circumference is 2* $\pi$ *2.5 m
Which is 5 $\pi$ m (choice B)

Hope this helped!

Which factor do 64x^2 + 48x + 9 and 64x^2 - 9 have in common?

Ber [7]

Start with the second expression. That factors easily into (8x-3)(8x+3).
Since 64x^2 + 48x + 9 has no negative signs, I'd bet that the common factor is (8x+3). Divide <span>64x^2 + 48x + 9 by that to verify.

1/15.999=x/54.5<br> Does anyone know what to do? I keep getting the answer wrong.

kkurt [141]

Hello!

First, let's write the problem.
$\frac{1}{15.999}=\frac{x}{54.5}$
Let's switch sides now, otherwise, we are going to end up doing it later.
$\frac{x}{54.5}=\frac{1}{15.999}$
Multiply both sides by 54.5.
$\frac{x}{54.5} *54.5 =\frac{1}{15.999}*54.5$
We could also rewrite that as,
$\frac{54.5x}{54.5}=\frac{1\cdot \:54.5}{15.999}$
Simplify.
$\frac{54.5x}{54.5}=x$
$\frac{1\cdot \:54.5}{15.999}=\frac{54.5}{15.999}$
$x=3.40646\dots$
That would be our final answer, we could round it to.
x ≈ 3.40

You can feel free to let me know if you have any questions regarding this!
Thanks!
