well to get decimal notation you would just multiply that out. so if you took 1.01x10^4 and multiply it out, it would equal 10,100.

[Right Triangles Only] SOHCAHTOA

[Right Triangles Only] sinθ = opposite over hypotenuse

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

Angle θ = 23°

Opposite Leg = <em>x</em>

Hypotenuse = 21

<u>Step 2: Solve for </u><em><u>x</u></em>

Substitute in variables [sine]: $\displaystyle sin(23^\circ) = \frac{x}{21}$
[Multiplication Property of Equality] Isolate <em>x</em>: $\displaystyle 21sin(23^\circ) = x$
Rewrite: $\displaystyle x = 21sin(23^\circ)$
Evaluate: $\displaystyle x = 8.20535$
Round: $\displaystyle x \approx 8.2$

Of 734 students, 442 are taking mathematics. What angle (in degrees) of a circle would show the percent of students taking mathe

Anestetic [448]

We need to find the angle (rounded to the nearest whole degree) of a circle that would represent the percent of students taking mathematics.

Since a complete turn around the circle has 360º, we have the following proportion:

<em>Number of students Angle</em>

734 360º

442 x

Then, cross multiplying the above values, we obtain:

$\begin{gathered} 734x=442\cdot360\degree \\ \\ x=\frac{442\cdot360\degree}{734} \\ \\ x\cong217\degree \end{gathered}$

<em>Answer</em>: 217º
