During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. Explain in words each step to find the following question:



At what number(s) measures played would the sound level be at 80 decibels?

Answers

Answer:

The numbers of measure of music played are 1 and 7

Step-by-step explanation:

Given

[tex]s = 10|x - 4| + 50[/tex]

Required

Solve for x when s = 80

Substitute 80 for x

[tex]80 = 10|x - 4| + 50[/tex]

Subtract 50 from both sides

[tex]80 - 50= 10|x - 4| + 50 - 50[/tex]

[tex]30= 10|x - 4|[/tex]

Divide through by 10

[tex]\frac{30}{10}= \frac{10|x - 4| }{10}[/tex]

[tex]3= |x - 4|[/tex]

Reorder

[tex]|x - 4| = 3[/tex]

This can be split into

[tex]x - 4 = 3[/tex] or [tex]x - 4 = -3[/tex]

Solve for x

[tex]x = 4 + 3[/tex] or [tex]x = 4 - 3[/tex]

[tex]x = 7[/tex] or [tex]x = 1[/tex]

Hence:

The numbers of measure of music played are 1 and 7

The points of concurrency of a triangle include the following:

The circumcenter of an obtuse triangle lies outside the triangle.The incenter of a right triangle lies inside the triangle.The point of concurrency of the angle bisectors of an acute triangle lies inside the triangle.The point of concurrency that is equidistant from the vertices of a right triangle lies on the triangle.

What is a triangle?

A triangle can be defined as a two-dimensional shape that is typically made up of three (3) sides, three (3) vertices and three (3) angles. This ultimately implies that, a polygon that has three (3) lengths of sides is a triangle.

Types of triangle

In Geometry, there are different types of triangle based on the length of their sides, vertices and angle, these include;

Equilateral triangleScalene triangleIsosceles triangleObtuse triangleRight triangle

What is a point of concurrency?

A point of concurrency refers to a single point that is shared by three (3) or more lines, segments, rays, or planes. Thus, a triangle is considered to be concurrent when three (3) or more lines intersect at a single point.

Step-by-step explanation:

-6x + 10 = -104

-6x = -114

x = 19

Answer:

[tex]\boxed {x = 19}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

-[tex]6x + 10 = -104[/tex]

-Subtract [tex]10[/tex] to both sides:

-[tex]6x + 10 - 10 = -104 -10[/tex]

-[tex]6x = -114[/tex]

-Divide both sides by [tex]6[/tex]:

[tex]\frac{-6x}{-6} = \frac{-114}{-6}[/tex]

[tex]\boxed {x = 19}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]19[/tex].

Answer:

Measure 1 is 112º

You know that 112º is the closest answer because you can see the angle is obtuse. And obtuse is an angle less than 180 but more than 90º

Step-by-step explanation:

So a straight line is equal to 180º so just set the equations equal to 180. Your final equation should look like (3x + 22) + (2x + 8) = 180

Now all you have to do is solve for x.

3x + 22 + 2x + 8 = 180

Combine like factors

3x + 2x = 5x

22 + 8 = 30

Now your equation should look like 5x + 30 = 180

Subtract 30 from both sides.                   -30       -30  

                                                                            ----------

                                                                                150

So now the equation should look like 5x = 150

Divide both sides by 5, 150/5 = 30

SO x = 30

Plug 30 in to the equation to check your answer

(3*30 + 22) = 112

(2*30 + 8) = 68

112 + 68 = 180

Marc mixes blue and yellow paint to make his favorite shade of green, which he'll use to paint his house. He has 14 cans of blue paint and 20 cans of yellow paint when he starts. He wants the same green color every time he mixes, so the amounts of blue and yellow must always be proportional to the original mixture. On day 1, he mixes 4 cans of blue and 6 cans of yellow. On day 2, he mixes 6 cans of blue and 9 cans of yellow. 1. In simplest form, what is the ratio of blue paint to yellow paint in the mixture? Type your answer in the space below.

Answers

Answer:

The answer is 0,66

Step-by-step explanation:

Assuming he gets the exact same shade of green everyday, the ratio of blue to yellow for Marc's green color is 0,66 because 4 / 6 and 6 / 9 give the same results when calculated in decimal.

Satellites in low-Earth orbit circle around our planet at about 4.72 miles per second. A satellite that relayed a phone text message traveled 16.52 miles before the message reached the recipient. How long did it take the text to go from phone to phone? It took the text seconds to go from phone to phone.

Answers

Answer: 3.5

Step-by-step explanation:

Divide 16.52 by 4.72. It equals 3.5.

Using the speed - distance relationship, the time it'll take for the text to travel from phone to phone is 3.5 seconds.

Given the parameters :

Transmission speed = 4.72 miles per second

Distance traveled = 16.52 miles

Recall :

Time = Distance ÷ Speed

Time taken = (16.52 / 4.72) = 3.5 seconds.

The time it took the text to travel from phone to phone is 3.50 seconds.

What is the expression?

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

The expression is given in the question as follows:

6(-3w+1/3)

We have to expand the given expression by using the distributive property.

As per the question, we have

⇒ 6(-3w+1/3)

Apply the distributive property of multiplication,

⇒ 6 × (-3w)+ 6 × (1/3)

⇒ -18w + 6/3

⇒ -18w + 2

Therefore, the resultant expression is -18w + 2.
