Answer:

The decibel level of this second sound is 48.021 decibels.

Step-by-step explanation:

The acoustic intensity ([tex]B_{dB}[/tex]), measured in decibels, is defined by the following formula:

[tex]B_{dB} = 10\cdot \log_{10}\left(\frac{I}{I_{o}} \right)[/tex] (1)

Where:

[tex]I_{o}[/tex] - Reference sound intensity, measured in watts per square meter.

[tex]I[/tex] - Real sound intensity, measured in watts per square meter.

If we know that [tex]B_{dB} = 42\,dB[/tex] and [tex]I_{o} = 10^{-12}\,\frac{W}{m^{2}}[/tex], then the real sound intensity of the first sound is:

[tex]\frac{B_{dB}}{10} = \log_{10}\left(\frac{I}{I_{o}} \right)[/tex]

[tex]\frac{I}{I_{o}} = 10^{\frac{B_{dB}}{10} }[/tex]

[tex]I = I_{o}\cdot 10^{\frac{B_{dB}}{10} }[/tex]

[tex]I = \left(10^{-12}\,\frac{W}{m^{2}} \right)\cdot 10^{\frac{42\,dB}{10} }[/tex]

[tex]I = 1.585\times 10^{-8}\,\frac{W}{m^{2}}[/tex]

The real sound intensity of the second sound is four times greater, that is:

[tex]I' = 6.340\times 10^{-8}\,\frac{W}{m^{2}}[/tex]

If we know that [tex]I_{o} = 10^{-12}\,\frac{W}{m^{2}}[/tex] and [tex]I' = 6.340\times 10^{-8}\,\frac{W}{m^{2}}[/tex], then the acoustic intensity of the second sound is:

[tex]B_{dB} = 10\cdot \log_{10}\left(\frac{I'}{I_{o}} \right)[/tex]

[tex]B_{dB} = 10\cdot \log_{10}\left(\frac{6.340\times 10^{-8}\,\frac{W}{m^{2}} }{10^{-12}\,\frac{W}{m^{2}} } \right)[/tex]

[tex]B_{dB} = 48.021\,dB[/tex]

The decibel level of this second sound is 48.021 decibels.

Answer:

5) we get a=6

6) we get c=8

Step-by-step explanation:

The triangles given are similar.

When the triangles are similar, the ratio of corresponding sides are also similar.

5) If c = 12, find a

We will use the ratio

[tex]\frac{30}{12}=\frac{15}{a}[/tex]

Now cross multiply to find value of a

[tex]30*a=12*15\\a=\frac{180}{30}\\a=6\\[/tex]

So, we get a=6

6. If b = 6.4, find c

We will use the ratio

[tex]\frac{30}{c}=\frac{24}{6.4}[/tex]

Now cross multiply to find value of b

[tex]30*6.4=24*c\\c=\frac{192}{24}\\c=8\\[/tex]

So, we get c=8

Answer:

The formula for the gray squirrel population is [tex]n = 3125\cdot 2^{\frac{t}{6} }[/tex].

Step-by-step explanation:

The statement indicates that gray squirrel population increases geometrically, population is doubled every 6 years. That is:

[tex]\frac{n_{t+6}}{n_{t}} = 2[/tex] (1)

If the population after 30 years is 100000, then we construct the following relationship:

[tex]\frac{n_{6}}{n_{o}} \cdot \frac{n_{12}}{n_{6}}\cdot \frac{n_{18}}{n_{12}}\cdot \frac{n_{24}}{n_{18}}\cdot \frac{n_{30}}{n_{24}} = 2^{5}[/tex]

[tex]n_{30} = 2^{5}\cdot n_{o}[/tex]

[tex]n_{o} = \frac{n_{30}}{2^{5}}[/tex] (2)

[tex]n_{o} = \frac{100000}{2^{5}}[/tex]

[tex]n_{o} = 3125[/tex]

A geometric progression for the grey squirrel population is defined by the following formula:

[tex]n = 3125\cdot 2^{\frac{t}{6} }[/tex] (3)

Where:

[tex]t[/tex] - Time, measured in years.

[tex]n[/tex] - Population of gray squirrels.

Answer:

[tex]\sqrt{106}[/tex] units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 9, 5)

d = [tex]\sqrt{(-9-0)^2+(5-0)^2}[/tex]

   = [tex]\sqrt{(-9)^2+5^2}[/tex]

   = [tex]\sqrt{81+25}[/tex]

    = [tex]\sqrt{106}[/tex]

Answer:

x = 43000/9 or 4777.7 (i'm not 100% sure on this, so i apologize if i'm incorrect)

Step-by-step explanation:

The equation you were given was:

amount of solution • rate of concentration = amount of pure acid

By looking at the question, you can conclude that the amount of solution being used is 18%. You need to turn that into a decimal, therefore it'd be 0.18.

You can also conclude that the amount of pure acid being used is 860 milliliters. So, from this, you're able to fill in 2 parts of the equation:

0.18 • x = 860 mL

Now, all there's left to do is solve for x! To do this ,you'll need to rearrange the multiplication problem into a division problem.

860 / 0.18 = x

x = 43000/9 or 4777.7

x=1200

Answer:

i think its 32 pints

Step-by-step explanation:

im pretty sure but sorry if im wrong ❤️

The remaining honey in the beehive is 4 gallons and 2 quarts, or 4 quarts and 2 ounces.

we need to convert the given measurements to quarts and ounces and then subtract them from the original 5 gallons.

1 gallon is equal to 4 quarts, and 1 quart is equal to 32 ounces.

4 gallons can be converted to quarts by multiplying by 4:

4 gallons × 4 quarts/gallon = 16 quarts

1 pint is equal to 2 cups, and 1 cup is equal to 8 fluid ounces.

1 pint and 2 ounces can be converted to ounces:

1 pint × 2 cups/pint × 8 ounces/cup = 16 ounces

2 ounces (already in ounces) = 2 ounces

Now, let's add up the converted measurements:

16 quarts + 16 ounces + 2 ounces = 16 quarts and 18 ounces

To find the remaining honey, we subtract the converted measurements from the original 5 gallons:

5 gallons - 16 quarts - 18 ounces = 4 gallons and 2 quarts
