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?

Answer:

The expression is (m/3 + 2) inches

Step-by-step explanation:

Quotient simply is the result of division.

Thus, the quotient we are dealing with is m/3

So, since George’s height is 2 in taller than this quotient, we have his height as;

(m/3 + 2) inches

Answer:

126

Step-by-step explanation:

Dale spends 12 hours on the internet, 75% on messages and 25% on games.

To make this easier, we can just convert the percentages into fractions and then continue.

To turn a percentage into a fraction, take the percentage number and put it into the numeriator, and add 100 to the denominator.

75% = 75/100  

25% = 25/100

Simplify!

75% = 75/100 = 3/4

25% = 25/100 = 1/4

So, now we know how to convert the percentages into a fraction. Now! We must use the fractions to find out how to find the time he uses to play games.

We know now that he spends 1/4 of his time working on games, and 3/4 of his 12 hours working on messages. However, we want to know how much 1/4 is. Divide 12 by the denominator, 4, and this will determine how long 1/4 is.

12 / 4 = 3  

So, that means that of his 12 hours he spends on the internet, he spends 3 hours doing games.

Now, subtract the time he spends doing the games by the time he spends on the internet to find the time on he spends messaging.

12 - 3 = 9

Which means that:

9 = Hours Spent Doing Messaging

3 = Hours Spent Playing Games

Answer:

56 deceased by 14% is 48.16

262 decreased by 39% is 159.82

Answer:

B

Step-by-step explanation:

Solution,

here,

slope(m)=-5

passing point;(-1 , -8)=(x1 , y1)

Using the formula:y-y1=m(x-x1)

or,y-(-8)= -5[x-(-1)]

or,y+8=-5x-5

.°.y= -5x-13

If L || M. Then the value of the variable 'x' will be 17.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees.

The side of the rectangle is L and M. If L || M.

L = 8x + 20

M = 11x - 31

Then the value of 'x' is given as,

M = L

11x - 31 = 8x + 20

11x - 8x = 20 + 31

3x = 51

x = 17

If L || M. Then the value of the variable 'x' will be 17.

Answer:

8 more men are needed to complete the job

Step-by-step explanation:

Proportions

This problem can be solved by step-by-step reasoning applying proportions:

The above statement stands because the fewer hours of work, the more time the job needs to be completed. Let's continue.

The same reasoning applies here, fewer men=more days.

Now for the second condition. Increase the hours/day:

More hours/day=less days to complete the job

We know this last time is 12 days, thus:

[tex]\displaystyle 12=\frac{14*9*16}{7*x}[/tex]

Solving for x:

[tex]\displaystyle x=\frac{14*9*16}{7*12}=\frac{2016}{84}=24[/tex]

24 men are needed now, this is an increase of 24-16=8 more men

8 more men are needed to complete the job

Step-by-step explanation:

The number expression 5⁻¹⁵ rewritten using a positive exponent as -5¹⁵ option (A) -5¹⁵ is correct.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that:

The number expression is:

= 5⁻¹⁵

By the property of the integer exponent we can write the above number exponent as follows:

= (5¹⁵)(-1)¹⁵

(-1)¹⁵ = -1   (because 15 is the odd number)

= -5¹⁵

Thus, the number expression 5⁻¹⁵ rewritten using a positive exponent as -5¹⁵ option (A) -5¹⁵ is correct.

Step-by-step explanation:

You can solve this with kinematics or with energy.

Using kinematics, given:

v₀ = 600 m/s

v = 200 m/s

Δx = 0.05 m

Find: a

v² = v₀² + 2aΔx

(200 m/s)² = (600 m/s)² + 2a (0.05 m)

a = -3,200,000 m/s²

Given:

v₀ = 600 m/s

v = 0 m/s

a = -3,200,000 m/s²

Find: Δx

v² = v₀² + 2aΔx

(0 m/s)² = (600 m/s)² + 2(-3,200,000 m/s²) Δx

Δx = 0.05625 m

So the bullet needs to travel an additional 0.00625 m, or 0.625 cm.

Using energy, the work done on the bullet equals the change in kinetic energy.

ΔKE = W

½ mv² − ½ mv₀² = Fd

½ m (200 m/s)² − ½ m (600 m/s)² = F (0.05 m)

(-160,000 m²/s²) m = F (0.05 m)

F/m = -3,200,000 m/s²

½ mv² − ½ mv₀² = Fd

½ v² − ½ v₀² = (F/m) d

½ (0 m/s)² − ½ (600 m/s)² = (-3,200,000 m/s²) d

d = 0.05625 m
