Find an equivalent expression using the Distributive Property. x(4+y)

Answer:

140 db

Step-by-step explanation:

I have succesfully finished tihs

The value is closest to the sound level of the vocalizations of a blue whale is 140dB.

We have given that,

Intensity(I)= 106.8 watts/meter^2

The intensity of sound hair by the human ear is,

\(I_0=1\times10^{-12}\)

Sound intensity is defined as the power carried by sound waves per unit area in a direction perpendicular to that area.

We have to find which value is closest to the sound level, in decibels, of the vocalizations of a blue whale

So we have given the formula

\(B=10 log(\frac{I}{I_0} )\)

So use the given value we get

\(B=10 log(\frac{106.8}{1\times 10^{-12}} )\)

B= 140.28 dB≈140 dB

Therefore the value is closest to the sound level of the vocalizations of a blue whale is 140dB.

Volume of 19.6 g of a liquid that has a density of 0.967 g/ml is 20.3

Volume and density are connected by a particular substance's mass. The relationship between mass and volume can be easily determined using density; for example, the mass of a body is equal to its volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d).

Density decreases when volume increases without accompanying increases in mass.

here,

Density = mass/volume

or, Volume = mass/density

or, volume = 1.96g/0.967 g/ml

or, volume = 20.268 ml (nearly equal to 20.3)

so, Volume of 19.6 g of a liquid that has a density of 0.967 g/ml is 20.3

For each cup of sugar, we need 5/3 cups of milk.

A fraction is used to express a portion of a whole or a ratio of two values. It is represented by a numerator and a denominator separated by a horizontal line, with the numerator above and the denominator below.

To find : how much milk is needed for each cup of sugar

we need to use the given ratio of sugar to milk and invert it:

1/5 cup of sugar per 1/3 cup of milk

To find how much milk is needed for each cup of sugar, we need to divide the amount of milk by the amount of sugar:

(1/3 cup of milk) ÷ (1/5 cup of sugar) = (1/3) × (5/1) = 5/3 cup of milk per cup of sugar

Therefore, for each cup of sugar, we need 5/3 cups of milk.

The rate of change of the top of the ladder with respect to x is -x/y

Step-by-step explanation:

The given parameters are;

The length of the ladder = 10 ft.

The horizontal distance of the bottom of the ladder from the wall = x

The distance of the top of the ladder from the floor = y

By Pythagoras's theorem, we have;

10 = y² + x²

Therefore, we have;

x² = 10 - y²

d(x²)/dx = 2·x =  d(10 - y²)/dx = -2·y·dy/dx

∴ 2·x = -2·y·dy/dx

dy/dx = 2·x/(-2·y) = -x/y

Therefore, the rate of change of the top of the ladder with respect to x, dy/dx = -x/y.

The relationship between two integers a and b, where a is a divisor of b, can be expressed using the existential quantifier. We can say that "a divides b" if and only if there exists an integer k such that:

b = ak

In other words, a divides b if and only if there exists an integer k such that b can be expressed as the product of a and k.

We can also express this relationship using the universal quantifier by saying that for all integers a, b, and k:

a divides b if and only if b = ak for some integer k

Both the existential and universal quantifier definitions of divisibility are equivalent and can be used interchangeably. The use of quantifiers allows us to make precise mathematical statements about the relationships between integers and the properties of the integers themselves.

The ratios of (a) square kens to square meters (1 ken² / 1 m²) is 3.88

For given question,

We have been given the unit conversion.

A traditional unit of length in Japan is the ken

and 1 ken = 1.97 m

We need to find the the ratios of (a) square kens to square meters.

First we find the square of 1 ken.

⇒ 1 square kens = (1.97 m)²

⇒ 1 square kens = 1.97 × 1.97 m²

⇒ 1 square kens = 3.88 m²                  ..................(1)

And 1 square meters = 1 m²                 ................. (2)

Now we take the ratio of square kens to square meters.

From (1) and (2),

⇒ 1 ken² / 1 m² = 3.88 / 1

⇒ 1 ken² / 1 m² = 3.88

Therefore, the ratios of (a) square kens to square meters (1 ken² / 1 m²) is 3.88

Rs 11115.5

Step-by-step explanation:

Selling price =Rs 9600

%loss = cost price - selling price. ×100

cost price.

5 = cost price - Rs 9600 ×100

cost price

Let Cp = cost price

5Cp = 100Cp - Rs 960000

5Cp - 100Cp = - Rs 960000

-95Cp = -Rs 960000

Cp = 960000/95

Cp = Rs 10105

%profit = Sp - Cp ×100

Cp

10 = Sp - 10105 ×100

10105

(10105×10)/100 = Sp - 10105

1010.5 = Sp -10105

Sp = 1010.5 +10105

Sp = Rs 11115.5

Answer:

  D)  Hungary

Step-by-step explanation:

You are being asked to compare 4 pairs of numbers. The population will have decreased if the number in the 2005 column is less than the number in the 1985 column.

Whenever you compare numbers, you start with the most-significant digit. If the most-significant digit has a higher place value, the number is larger. If the digits have the same place value, the number with the larger digit is larger. If no determination can be made by these comparisons, then the digits to the immediate right are compared.

  27,... > 19,...  2 > 1 in the 10-millions place

  10,... > 9,...  1 has a greater place value

  29... > 24...  comparison shifts to the 10-thousands place: 9 > 4

  10,058,... < 10,649,... . . . . the population decreased (0 < 6)

The "population decreased" result is found on the last line of the table, identified by the Country name "Hungary."

Hungary's population decreased from 1985 to 2005.

People often draw hypothesis in research.  Based on executing the test  We reject the null hypothesis; the mean delivery time is different for every day of the week.

Why do we reject the null hypothesis?

Note that if the p-value of an experiment (Like the one above) is less than or found to be equal to the significance level of your test, one can reject the null hypothesis.

a radio station has accepted 26 as the mean age of its listeners. one radio station executive claims that the mean age of its listeners is different from 26

By that, we known that the data is in favors the alternative hypothesis. Hence the results gotten by you are statistically significant. If your p-value is found to be greater than your significance level, you then fail to reject the null hypothesis.

The first step in correct of Luis’s, because he flipped the inequality sign when he subtracted.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

Given inequality is 7.2b + 6.5 > 4.8b – 8.1.

We can solve this inequality in many ways.

As Amelia, we can subtract 7.2b from both sides and get 6.5 > –2.4b – 8.1.

As Shauna after subtracting 6.5 from both sides, we get 7.2b > 4.8b – 14.6.

As Clarence, after adding 8.1 to both sides, we get, 7.2b + 14.6 > 4.8b.

Luis started by subtracting 4.8b from both sides to get 2.4b + 6.5 < – 8.1.

This is incorrect because the inequality symbol is flipped. It is not needed to flip the inequality symbol in subtraction.

Hence the incorrect first step is Luis’s, because he flipped the inequality sign when he subtracted.

Answer:

Step-by-step explanation:

We can defined the amplitude of a wave as the height of it, because it's the distance from the maxium point to the minimum point. In other words, it's the longest vertical displacement along the wave.

Additionally, amplitude represents power, when we apply waves to real phenomenons like the sound. So, greater grade of amplitude would represent louder sounds.

Therefore, the increase of amplitude would increase distance between the maximum and minimun point of the wave.
