Answer: 219.94\ cm^2

Step-by-step explanation:

Given

The central angle of a sector measures 175^{\circ}

The radius of the circle is r=12\ cm

The area of the sector is given by

\Rightarrow A=\dfrac{\theta }{360^{\circ}}\pi r^2

Insert the values

\Rightarrow A=\dfrac{175^{\circ}}{360^{\circ}}\cdot \pi \times 12^2\\\\\Rightarrow A=219.94\ cm^2

Ollie Drank 3/4 of a 16 oz bottle of juice. How many oz of juice is left in the bottle?
Alenkinab [10]
3/4th of the bottle of juice would be splitting up the 16 oz bottle into 4th, so 16 divided by 4 equals 4. Then because he only drank 3/4th of the bottle multiply the 4 by 3 equaling 12. Then subtract 12 from 16 and you get a total of 4 oz left!!!

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by
IrinaK [193]

Answer:

<em>The sound level would be at 80 decibels at 1 or 7 number of measures played</em>

Step-by-step explanation:

<u>Equations with Absolute Values</u>

We have the function s to represent the sound level in decibels:

s = 10|x - 4|+ 50

Where x is the number of measures of the music played.

We are required to find the value of x that makes s=80 decibels. We have to find the equation:

10|x - 4|+ 50 =80

Subtracting 50:

10|x - 4| =80-50

10|x - 4| =30

Dividing by 10:

|x - 4| =30/10=3

|x - 4| =3

For the absolute value be equal to 3, its argument could be positive or negative:

x-4=3

Or

x-4=-3

This leads us to two solutions:

x=3+4=7

x=7

Or

x-4=-3

x=4-3=1

x=1

The sound level would be at 80 decibels at 1 or 7 number of measures played
