The area of a compact disc is 452 4/7 square centimeters. What is the diameter of a compact disc ? Use 22/7 as an approximation
motikmotik

\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\ \cline{1-1} A=452\frac{4}{7} \end{cases}\implies 452\frac{4}{7}=\pi r^2\implies \cfrac{3168}{7}=\pi r^2 \implies \cfrac{3168}{7\pi }=r^2 \\\\\\ \stackrel{\pi =\frac{22}{7}}{\cfrac{3168}{7\cdot \frac{22}{7}}}=r^2\implies \cfrac{3168}{22}=r^2\implies 144=r^2\implies \sqrt{144}=r\implies 12=r \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill \stackrel{diameter=2r}{d=24}~\hfill

If P(x) = P<img src="https://tex.z-dn.net/?f=_%7Bn%7D" id="TexFormula1" title="_{n}" alt="_{n}" align="absmiddle" class="latex-f
seropon [69]

If P(x) = p_nx^n + p_{n-1}x^{n-1}+\ldots+p_0 is divided by (x-a), then P(x) = (x-a) \cdot Q(x) + R(x) for some polynomials Q,R. Moreover, \deg R < 1 (because \deg (x-a) = 1), so there exists  \alpha \in \mathbb{R} such that R(x) = \alpha for all x \in \mathbb{R}. But if we calculate P(a), it turns out that P(a) = (a-a)\cdot Q(a) + \alpha, so R(x) = \alpha = P(a). \blacksquare

The sum of two angles in a triangle totals 62.5 degrees. What is the other angles measure?
Advocard [28]
**All 3 angles of a triangle have a sum of 180°.**

So if 2 of those 3 angles are 62.5°, you would just subtract that by 180°.

180 - 62.5 = 117.5

The third angle would have to be 117.5°.
