Step-by-step explanation:

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,

[tex]I_0=1\times10^{-12}[/tex]

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

[tex]B=10 log(\frac{I}{I_0} )[/tex]

So use the given value we get

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

B= 140.28 dB≈140 dB

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

Answer:

B for sure

Step-by-step explanation:

The amount of energy used decreases by a different amount each year.

Option B is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

From the table,

Amount of energy used.

First-year: 1,000,000

Second-year: 900,000

Third year: 810,000

Fourth-year: 792,000

The difference between the amount of energy between consecutive years.

1,000,000 - 900,000 = 100,000

900,000 - 810,000 = 90,000

810,000 - 792,000 = 18,000

We see that,

There is a different amount of energy decreasing each year.

Thus,

The amount of energy used decreases by a different amount each year.

Answer:

y=6. &. x = -10

Step-by-step explanation:

if 4x + 5y = -10

then 4x = -10 -5y. ---------->(1)

if 4x + 3y = -22

then 4x = -22 -3y. ------------>(2)

from equation (1) & (2) :

then -10 -5y = -22 -3y

then 22 -10 = 5y -3y

12 = 2y

then y=6

substituting in (1) or (2):

then. x= -10

Answer:

A 159.25 to the second power

Step-by-step explanation:

he simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Answer: y=7

Answer:

16

Step-by-step explanation:

each pound has 3.6 cups

1/4 of a pound can be multiplied

3.6 x 1/4 =  0.9

then we subtract 4 - 3.6 = 0.4 say if the question was for one pound

But we have to find  14.4 cups instead as;

3.6 x 4 = 14.4 = 4 pounds

We go back to 0.9 are first smaller serving = 1/4 cup

14.4/0.9 = 16

Answer:

60 minutes

Step-by-step explanation:

Time taken to rake 12ft² = 10 minutes

Area of Mindy's rectangular path :

Area of rectangle = Length * Width

Dimension of Mindy's rectangular path = 9ft by 8ft

Area = 9ft * 8ft

Area = 72ft²

Hence, it will take Mindy;

(Area of Mindy's path / 12 ft) * time taken

(72ft² / 12ft²) * 10 minutes

6 * 10 = 60 minutes

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - seven eighths minus four-fifths = three fortieths.

Exponentiation: the result of step No. 1 ^ 2 = 3/

In words - three-fortieths squared = nine one-thousand six-hundredths.

Answer: 30% or 3/10

Step-by-step explanation:

First you need to figure out how many balls are in the bag. There is 1 red, 3 blue, and 2x (x=# of blue balls) green balls. since there is 3 blue balls you double 3 to get how many green balls there are, which is 6. Then you do 1+3+6 to give you 10. Since there is 3 blue balls in a bag that consists of 10 balls, you have a probability of 3/10 or 30% or .3 to draw a blue ball.
