Answer: Find the measures of an exterior angle and an interior angle given the number of sides of each regular polygon. Round to the nearest tenth, if necessary. 24 b 15, 345 24, 156 7.5, 172.5 15, 165​

Step-by-step explanation:  sum, S, of the measure of the interior angles of a polygon with n sides is: ... The sum of the interior angles of a 24 -gon is 3960. ... angles of a polygon is (n−2)⋅180 , where n is the number of sides. ... Each exterior angle measures 36024=15 . ... The sum of the 24 interior angles is then 24⋅165=3960 .

By applying Cramer's rule as solution method, the solution of the linear system 3 · x + 2 · y = 5 and x + 3 · y = 4 is equal to the set (x, y) = (1, 1).

Determinants are constructions studied in linear algebra and related to matrices, one of the most common applications of determinants is the solution of linear equations, whose simplest form is known as the Cramer's rule.

Now we proceed to use this rule to get the solution of the linear system:  

[tex]x = \frac{\left|\begin{array}{cc}5&2\\4&3\end{array}\right| }{\left|\begin{array}{cc}3&2\\1&3\end{array}\right|}[/tex]

[tex]x = \frac{(5)\cdot (3)-(4)\cdot (2)}{(3)\cdot (3) -(1)\cdot (2)}[/tex]

x = 1

[tex]y = \frac{\left|\begin{array}{cc}3&5\\1&4\end{array}\right| }{\left|\begin{array}{cc}3&2\\1&3\end{array}\right|}[/tex]

[tex]y = \frac{(3)\cdot (4) - (5)\cdot (1)}{(3)\cdot (3) - (1)\cdot (2)}[/tex]

y = 1

By applying Cramer's rule as solution method, the solution of the linear system 3 · x + 2 · y = 5 and x + 3 · y = 4 is equal to the set (x, y) = (1, 1).

Answer:

£268.8

Step-by-step explanation:

192 = 100%

19.2= 10%

19.2 x 4 = 76.8

76.8 = 10%

76.8 + 192 = 268.8

Answer:

The condensed log equation is: [tex]\log{\frac{x^4y}{z^5}}[/tex]

Step-by-step explanation:

We use these following logarithm properties to solve this question:

[tex]a\log{x} = \log{x^a}[/tex]

[tex]\log{a} + \log{b} = \log{ab}[/tex]

[tex]\log{a} - \log{b} = \log{\frac{a}{b}}[/tex]

In this question:

[tex]4\log{x} = \log{x^4}[/tex]

[tex]5\log{5} = \log{z^5}[/tex]

So

[tex]4\log{x} + \log{y} - 5\log{z}[/tex]

Becomes:

[tex]\log{x^4} + \log{y} - \log{z^5}[/tex]

Now applying the addition and subtraction properties, we have:

[tex]\log{\frac{x^4y}{z^5}}[/tex]

The condensed log equation is: [tex]\log{\frac{x^4y}{z^5}}[/tex]

Answer:

2

Step-by-step explanation:

Rearrange to same form:

2y = -5x + 10

y = -5/2x + 10

ay = -5x + 4

Parallel lines have no intersection and solution, thus a = 2

Answer:

Step-by-step explanation:

For there to be no solution the lines must be parallel and have different y intercepts. To be parallel they must have the same slope.

Solving each for y

y=(10-5x)/2 and y=(4-x)/a

So the slopes are

-5/2 and -1/a, if they are equal

-5/2=-1/a

-5a=-2

a=2/5

Step-by-step explanation:

Exponential equation for amount of substance:

The exponential equation for the amount of a substance is given by:

[tex]A(t) = A(0)(1-r)^t[/tex]

In which A(0) is the initial amount and r is the decay rate, as a decimal, and t is the time measure.

An element with mass 510 grams decays by 26.3% per minute.

This means that [tex]A(0) = 510, r = 0.263[/tex]

So

[tex]A(t) = A(0)(1-r)^t[/tex]

[tex]A(t) = 510(1-0.263)^t[/tex]

[tex]A(t) = 510(0.737)^t[/tex]

How much of the element is remaining after 7 minutes?

This is A(7). So

[tex]A(7) = 510(0.737)^7 = 60.2[/tex]

60.2 grams is remaining after 7 minutes.

A pair of complementary angles, when added, equal 90. So if <5 is 59 degrees, what do you do to find <6? You subtract 59 with 90.

90-59=31

So <6 is 31 degrees.

Bearing of the flight from Elgin to Canton is:

Answer:

235°

Step-by-step explanation:

Bearing: The angle (in degrees) measured clockwise from north.

The given scenario can be modeled as a triangle.

Given sides of the triangle:

As due north is at a right angle to due west, the angle in the right corner of the triangle is:

⇒ 90° - 44° = 46°

Use the Sine Rule to find angle y marked on the attached diagram (the angle opposite side b).

Sine Rule

[tex]\sf \dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

[tex]\implies \sf \dfrac{\sin 46^{\circ}}{680}=\dfrac{\sin y}{545}[/tex]

[tex]\implies \sf \sin y= \dfrac{545\sin 46^{\circ}}{680}[/tex]

[tex]\implies \sf y= \sin^{-1} \left(\dfrac{545\sin 46^{\circ}}{680}\right)[/tex]

[tex]\implies \sf y=35.20682806...^{\circ}[/tex]

Interior angles of a triangle sum to 180°

⇒ x° + y° + 46° = 180°

⇒ x° + 35.2068...° + 46° = 180°

⇒ x° = 98.79317194...°

Consecutive Interior Angles Theorem

When a straight line intersects two parallel straight lines, the consecutive interior angles formed sum to 180°.  Therefore the angle between due north and side a of the triangle is:

⇒ 180° - 44° = 136°

To find the bearing of the flight from Elgin to Canton, find the angle labelled green on the attached diagram:

[tex]\implies \sf Bearing =136^{\circ}+ 98.79317194...^{\circ}[/tex]

[tex]\implies \sf Bearing = 234.7931719...^{\circ}[/tex]

[tex]\implies \sf Bearing = 235^{\circ}[/tex]

As bearings are usually given as a three-figure bearings, the bearing of the flight from Elgin to Canton is 235°.
