Answer:

M=1

Step-by-step explanation:

9-6m=3m

you need to get rid of the 6 so you:

9-6m = 3m

+6m +6m

9= 9m

$\frac{9}{9}$ $\frac{9m}{9}$

1=m

What is the approximate radius of a sphere with a volume of 34 cm3?

xz_007 [3.2K]

Answer:

Step-by-step explanation:

The formula of a volume of a sphere:

$V=\dfrac{4}{3}\pi R^3$

R - radius

We have

$V=34\ cm^3$

Substitute:

$\dfrac{4}{3}\pi R^3=34$ multiply both sides by 3

$3\!\!\!\!\diagup^1\cdot\dfrac{4}{3\!\!\!\!\diagup_1}\pi R^3=(3)(34)$

$4\pi R^3=102$ divide both sides by 4

$\dfrac{4\pi R^3}{4}=\dfrac{102}{4}$

$\pi R^3=\dfrac{51}{2}$ divide both sides by π

$\dfrac{\pi R^3}{\pi}=\dfrac{\frac{51}{2}}{\pi}$

$R^3=\dfrac{51}{2\pi}$ use π ≈ 3.14

$\R^3\approx\dfrac{51}{(2)(3.14)}$

$R^3\approx\dfrac{51}{6.28}\\\\R^3\approx8.121\to R\approx\sqrt[3]{8.121}\\\\R\approx2.01\ cm$

If you were asked to find the 87th term in a sequence, which formula would you want to be given?

koban [17]

To determine the nth term of sequence, first we need to know what type of sequence is it. It can be an arithmetic sequence or a geometric sequence. For an arithmetic sequence, the nth can be determined by the formula,

an = a1 + (n-1)d

For a geometric sequence,

an = a1r^n-1

Hope this answers the question.
