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 1

Hey Child.

The answer to this is 1 or 7:

To find the range for the number of measures played to satisfy our solution, we must solve for x using s = 80.

Next, we subtract 50 from both sides of the equation.

Next, we divide both sides of the equation by 10

Next, to eliminate the absolute value bars, we will add a ± sign in front of our s value, 3.

Finally, we add 4 to both sides of our equation giving us 4 ± 3 = x

Separating this into two equations, we get 4 - 3 = x and 4 + 3 = x

Therefore, x, the number of measures of music played, must be either 1 or 7.

The length y of a rectangle is four less than three times the width x. The perimeter of the rectangle is 16 cm.

Answers

Answer:

y = 1 cm

x = 7 cm

Step-by-step explanation:

x = 3y + 4

perimeter = 2 * ( y + x ) = 16

x + y = 8 by using x = 3y + 4

y + 3y + 4 = 8

4y = 4

y = 1

1 + x = 8

x = 7

y = 1 cm

x = 7 cm

1). y= 1/5x + 1

The perimeter of a rectangle is 54 feet. The width is 1 less
than the length. What are the dimensions of the rectangle?

Answers

Step-by-step explanation:

length=x

width=x-1

x + x + (x-1) + (x-1) = 54

4x - 2 = 54

4x = 56

x = 14 ft

x = 14 ft

x - 1 = 14 - 1 = 13 ft

x = 14 ft

x - 1 = 14 - 1 = 13 ft

Perimeter= x + x + (x-1) + (x-1)

54 ft = 14 + 14 + (14 - 1) + (14 - 1)

54 ft = 28 + (13 +13)

54 ft = 54 ft

A bacteria colony starts with 5 bacteria at the beginning and triples every hour. How would

you write an explicit equation to model this situation?

A. f(x) = 3.5*

B. f(x) = 3x + 5

C. f(x) = 5x + 3

D. f(x) = 5.3%

Answers

Answer:

B. f(x) = 3x + 5

Step-by-step explanation:

Initial amount of bacteria N0 = 5 bacteria's

If the triple every hour,

The increase in bacteria in the colony after x hour will be 3*x =3x

x is the amount of hour.

Total amount of bacteria in the colony after x hour will be N0 + 3x

Let f(x) be the total amount of bacteria in the colony after x hour

f(x) = N0+3x

Since N0 = 5

f(x) = 5+3x

Re-arrange

f(x) = 3x + 5

Hence an explicit formula to model the equation is f(x) = 3x + 5

There are 4 pints of green paint in a gallon bucket. The paint is made from equal amounts of yellow paint and blue paint. To create a different shade of green, the mixture needs to be 80% yellow. How many pints of yellow paint need to be added to the bucket to make the mixture 80% yellow? Brandon says to get that shade of green, 6 pints of yellow paint need to be added to the bucket. Bianca says that won't work. In two or more complete sentences, explain who is correct and why. In your explanation, include the calculations to support the correct answer.

Answers

Answer:

Brandon is correct.

Step-by-step explanation:

Initially, there id 4 pints of green paint in the bucket.

As the green paint is made from equal amounts of yellow paint and blue paint, so, the initial amount of yellow and blue paint in the bucket  is 2 pint each.

Let x pints of yellow paint to be added to the bucket to make the desired shade.

Total amount of the paint in the bucket, after addition of [tex]x[/tex] pints of yellow color become [tex]4 + x[/tex] pint, in which the ampunt of yellow color is [tex]2+x[/tex] pints.

As, the ampunt of yellow color is 80% of the total amount of the mixture, so

[tex](4+x)\times 80\%=2+x[/tex]

[tex]\Rightarrow (4+x)\times \frac{80}{100}=2+x[/tex]

[tex]\Rightarrow 4(4+x)=5(2+x)[/tex]

[tex]\Rightarrow x=6[/tex]

So, 6 pints of yellow paint to be added to the bucket to make the desired shade.

Hence, Brandon is correct.

Answer:

Brandon is correct that the mixture needs 6 more pints of yellow paint.

50%(4 pints) + 100%(x pints) = 80%(4 + x pints)

2 + x = 3.2 + 0.8x

0.2x = 1.2

x = 6

Bianca is correct because adding the 6 pints won't fit in the gallon bucket. Adding 6 pints of yellow to the original 4 pints of green is 10 pints, which will not fit in the 1-gallon bucket. (1 gallon = 8 pints)

C) Translated according to the rule (x, y) → (x + 2, y + 8) and reflected across the y-axis

D) Translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the x-axis​

Answers

Answer:

D) Translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the x-axis​

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and translation.

If a point X(x, y) is translated a units right and b units down, it new location is X'(x + a, y + b)

If a point X(x, y) is reflected across x axis, it new location is X'(x, -y)

Pentagon ABCDE is at A(-4, 5), B(-6, 4), C(-5, 1), D(-2, 2), E(-2, 4) while pentagon A"B"C"D"E" is at A"(4, -7), B"(2, -6), C"(3, -3), D"(6, -4), E"(6, -6)

If pentagon ABCDE is Translated according to the rule (x, y) → (x + 8, y + 2), the new points would be A'(4, 7), B'(2, 6), C'(3, 3), D'(6, 4), E'(6, 6). If a reflection across the x axis is the done, the new points are A"(4, -7), B"(2, -6), C"(3, -3), D"(6, -4), E"(6, -6)

Find the x- and y-intercepts of the graph of the linear equation 3x+6y=24.

Answers

Answer:

y=0,4 and x=8,0

The x and y-intercept of the linear equation 3x + 6y = 24 will be (8,0) and (0,4) respectively.

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given linear function,

3x+6y=24

At x-intercept, y = 0

3x = 24

x = 8 thus it will be (8,0).

At y-intercept , x = 0

6y = 24

y = 4 thus it will be (0,4)

Hence "The linear equation 3x + 6y = 24 will have x-intercepts of (8, 0) and (0, 4) correspondingly".

Answer: B) 6 servings

====================================================

Explanation:

5 & 1/3 is the mixed number with 5 as the whole part and 1/3 as the fractional part

Let's convert to an improper fraction

5 & 1/3 = 5 + 1/3

5 & 1/3 = 5*(3/3) + 1/3

5 & 1/3 = 15/3 + 1/3

5 & 1/3 = (15+1)/3

5 & 1/3 = 16/13

The mixed number 5 & 1/3 is equivalent to the improper fraction 16/3

-------------------

Each serving is 7/8 cup

x of these servings is (7/8)x

x is the number of servings in a full container, so

(7/8)x = 16/3

x = (16/3)*(8/7)

x = (16*8)/(3*7)

x = 128/21

x = 6.0952 approximately

x = 6 when rounding to the nearest whole number

So the container is about 6 servings.

The measure of the angles will be ∠1 = 78°, ∠2 = 102°, ∠3 = 78°, ∠4 = 102°, ∠5 = 38°, ∠6 = 142°, ∠7 = 38°, ∠8 = 142°, ∠9 = 78°, ∠10 = 102°, ∠11 = 78°, ∠12 = 102°, ∠13 = 38°, ∠14 = 142°, ∠15 = 38°, and ∠16 = 142°

What is an angle?

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

The type of angles is given below.

Two angles are said to be supplementary angles if their sum is 180 degrees.If two lines are parallel then the third line. The corresponding angles are equal angles.When two lines intersect, then their opposite angles are equal.

The measure of angle 7 is 38°. Angles 7 and 8 are supplementary angles.

∠7 + ∠8 = 180°

38° + ∠8 = 180°

∠8 = 142°

The measure of angle 10 is 102°. Angles 9 and 10 are supplementary angles.

∠9 + ∠10 = 180°

102° + ∠9 = 180°

∠9 = 78°

Then the measure of the remaining angles will be

∠1 = 78°

∠2 = 102°

∠3 = 78°

∠4 = 102°

∠5 = 38°

∠6 = 142°

∠7 = 38°

∠8 = 142°

∠9 = 78°

∠10 = 102°

∠11 = 78°

∠12 = 102°

∠13 = 38°

∠14 = 142°

∠15 = 38°

∠16 = 142°

Elion received the Nobel prize for medicine in 1988 along with George H. Hitchings and Sir James W. Black. The three were awarded the prize for their development of drugs used to treat several major diseases.Gertrude Belle Elion was born on Jan. 23, 1918, in New York City. She graduated from Hunter College in New York City with a degree in biochemistry in 1937. Unable to obtain a graduate research position because she was a woman, she took a series of jobs, including lab assistant, chemistry and physics teacher in New York City high schools, and research chemist. During this time she also took classes at New York University, where she earned a master's degree in 1941. Because she could not devote herself to full-time studies, Elion never received a doctorate.In 1944 Elion joined the Burroughs Wellcome Laboratories (now part of GlaxoSmithKline (a company that makes prescription medicines)). There she was first the assistant and then the colleague of Hitchings, with whom she worked for the next four decades. Elion and Hitchings developed an array (variety) of new drugs that were effective against leukemia, autoimmune disorders, urinary-tract infections, gout, malaria, and viral herpes. Their success was due primarily to their innovative (characterized by new or unique) research methods. Rather than using the trial-and-error approach used by previous pharmacologists, Elion and Hitchings examined the difference between the biochemistry of normal human cells and that of cancer cells, bacteria, viruses, and other pathogens (disease-causing agents). They used this information to create drugs that could target a particular pathogen without harming the human host's normal cells. Their methods enabled them to eliminate much of the guesswork and wasted effort typical in previous drug research.Although Elion officially retired in 1983, she helped oversee the development of azidothymidine (AZT), the first drug used in the treatment of AIDS. In 1991 she was awarded a National Medal of Science and was inducted into the National Women's Hall of Fame. She died on Feb. 21, 1999, in Chapel Hill, N.C.Student J.
