Answer:

Braylee’s music is 3 times louder than Jessica's

Step-by-step explanation:

Given

[tex]L = 10\log\frac{I}{I_0}[/tex]

[tex]I_0 = 10^{-12}[/tex]

Required

Number of times Braylee's music is louder than Jessica's

First, we calculate the loudness of Jessica's music.

From the question;

[tex]I = 10^{-9}[/tex]

So, we have:

[tex]L = 10\log\frac{I}{I_0}[/tex]

[tex]L = 10\log\frac{10^{-9}}{10^{-12}}[/tex]

Apply law of indices

[tex]L = 10\log{10^{12-9}}[/tex]

[tex]L = 10\log{10^3[/tex]

Apply law of logarithm

[tex]L = 3*10\log{10[/tex]

[tex]\log10 = 1[/tex]

So:

[tex]L_1 = 3*10*1 = 30[/tex]

First, we calculate the loudness of Braylee's music.

From the question;

[tex]I = 10^{-3}[/tex]

So, we have:

[tex]L = 10\log\frac{I}{I_0}[/tex]

[tex]L = 10\log\frac{10^{-3}}{10^{-12}}[/tex]

Apply law of indices

[tex]L = 10\log{10^{12-3}}[/tex]

[tex]L = 10\log{10^9[/tex]

Apply law of logarithm

[tex]L = 9*10\log{10[/tex]

[tex]L_2 = 9*10*1 = 90[/tex]

At this point, we have:

[tex]L_1 = 30[/tex] --- Jessica's

[tex]L_2 = 90[/tex] --- Braylee's

Divide L2 by L1 to get the required number of times

[tex]n = \frac{L_2}{L_1}[/tex]

[tex]n = \frac{90}{30}[/tex]

[tex]n = 3[/tex]

Answer:

D.

Step-by-step explanation:

Step-by-step explanation:

Angle M = Angle R

47x - 17 = 32x + 28

15x = 45

x = 3

Angle M = 47(3) - 17 = 124°

Angle R = Angle M = 124°

Angle Q = 180 - Angle M = 56°

Angle N = Angle Q = 56°

The graph of inequality that represents the scenario is graph (b)

The given parameters are:

People signed up = 4

People needed = At least 9

Represent the number of people who are still needed with x.

So, we have the following inequality expression

[tex]x + 4 \ge 9[/tex]

Subtract 4 from both sides

[tex]x \ge 5[/tex]

The above means that, 5 or more people are still needed

The statements that are necessary and sufficient to prove that ABCD is a parallelogram are, (B), (C) and (D).

A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

The area of a parallelogram is base multiples by height as two triangles form a parallelogram.

From the properties of parallelograms the statements that are necessary and sufficient to prove that ABCD is a parallelogram are,

[tex]\overline{AE}[/tex] ≅ [tex]\overline{CE}[/tex] and [tex]\overline{BE}[/tex] ≅ [tex]\overline{DE}[/tex]  as diagonal of a parallelogram bisect each other.

[tex]\overline{AB}[/tex] ≅ [tex]\overline{CD}[/tex] and [tex]\overline{BE}[/tex] ≅ [tex]\overline{CE}[/tex] opposite sides of a parallelogram are equal.

m∠ABC + m∠BAD is 180° as the sum of the adjacent sides in a parallelogram are supplementary.

Step-by-step explanation:

Answer:

50°

Step-by-step explanation:

Let :

Let the angle = x

Second angle = x + 10

Third angle = x - 10

Sum of angles in a triangle = 180

x + (x + 10) + (x - 10) = 180

x + x + 10 + x - 10 = 180

3x = 180

x = 180 / 3

x = 60

Smallest angle :

x - 10 = 60 - 10 = 50°

Given:

The right angle triangle with legs 4 units and 7 units.

To find:

The length of hypotenuse.

Solution:

Pythagoras theorem: In a right angle triangle,

[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]

Let x be the length of the hypotenuse.

Using the Pythagoras theorem for the given triangle, we get

[tex]x^2=4^2+7^2[/tex]

[tex]x^2=16+49[/tex]

[tex]x^2=65[/tex]

Taking square root on both sides, we get

[tex]x=\sqrt{65}[/tex]                [∵Side length cannot be  negative]

[tex]x\approx 8.06[/tex]

Therefore, the length of the missing side for the given right angle triangle is 8.06 units.

Answer:

x = 11.2

Step-by-step explanation:

hypotenuse = 8.4 (radius) + 5.6 = 14  

using the Pythagorean theorem:

x² = 14² - 8.4² = 196 - 70.56 =125.44

x = √125.44 = 11.2
